1. SAFETY INFORMATION

• This product is not waterproof. It is designed to be used indoors, or outdoors temporarily without

rain or water ingress. Except for the Fortress Solar Generator which is waterproof and designed

to be used indoors or outdoors.

• Some wires may be supplied in parallel sets. Do not separate them. Doing so will void the Solar

Generator warranty.

• Note: when connecting the charge controller to batteries, a small initialization spark is typical.

• Follow the directions for the charge controller and the inverter. Manuals are included in your

package.

• Please check the output voltage specifications “Voc”: of the solar panels. It must be the same

or less input voltage of the charge controller. Not following these guidelines could result in

damage to the charge controller.

• Keep away from any combustible material.

• Allow adequate ventilation. This unit generates heat; without proper ventilation it may overheat,

potentially causing a fire hazard. Think of it like a small space heater; just leave a few inches of

cleareance all around and avoid enviroments over 86°F (30°C)

• Leave the inverter power switch “off” whenever the box is not in use to help prevent draining the battery.

• Switch any device to be powered “off” before plugging into this device.

• Keep away from children.

• Use as intended only.

2. GENERAL INFORMATION

A solar generator is merely a battery or a bank of batteries being charged by solar panels. All

batteries must use a charge controller, and typically an inverter is required for using the power

stored in the battery bank.

Cutting Edge Power Solar Generators always include the charge controller, and depending

on the user’s choices: the batteries, the inverter and the solar panels.

2.1 COMMON PARTS AMONG THE DESIGNS

2

12V Socket:

- Input and Output.

- Plug a Cutting Edge Power Mini Wind Turbine, and/or a car charger,

to charge your battery or batteries.

- Power any device up to 30A (360W max output)

30A Circuit Breaker:

- Protects the socket(s): It automatically disconnects the 12V sockets

when current AMP exceeds 30A (Total combined including all 12V

sockets). To turn them back on, wait a couple of minutes until the

Circuit Breaker cools down, then press the button. (No need to take

the cap off)

Terminal Posts:

- Input/Output

- Meant for connecting extra batteries, powering external inverters,

connecting battery chargers, others devices, etc.

- To connect additional battery in Parallel: Remove the caps, connect

negative wire to black post, and positive to red. We highly recommend

using a Cutting Edge Power Series/Parallel Kit.

- Use 6 AWG 90°C Wire. Ideally larger wire size. If in doubt, use larger

size wire or additional Parallel sets.

Series/Parallel Kit

- For wiring extra batteries.

2.2 QUICK START

1.Connect the red cable(s) to the positive terminal of the

battery bank. Then, connect the black cable(s) to the

negative terminal of the battery bank.

• When connecting the charge controller to batteries, a

small initialization spark is typical.

• Battery connection types may vary. As long as the ring

terminals are fastened tight (snug) and cannot

accidentally be pulled off the battery, the connection is

acceptable.

• Solar generators equipped with battery switches (Rebel,

Trailblazer, Scout and Fortress): turn the black knob

clockwise. Tighten as much as possible by hand. Not

tightening this switch may cause intermittent issues with

solar generator output. If you are experiencing

connection issues, check this switch first. Do not use a

hand tool to tighten the battery switch as overtightening

could damage it.

2. Plug the solar panel(s).

3. Plug devices to the inverter and turn the

inverter on.

3. ABOUT THE CHARGE CONTROLLER

Cutting Edge Power Solar Generators use two different MPPT charge controllers. They are

always prewired, and preset for 12V Lead Acid Batteries (Blue Charge Controller) , or

Lithium ion batteries if equipped (CEP200 Black MPPT charge controller)

Please refer to the manuals respectively for further information. Manuals are supplied with

the solar generators, and published in the Drawings and Instructions page on our website:

4. ABOUT THE SOLAR PANELS

When using the Blue MPPT Charge Controller:

First, make sure your Voc Solar Panel Voltavge is under 23V DC. If so, use any size solar panel,

(ex: 100W, 200W), up to 100A (0-1200W) whichever limitation comes first. If using multiple solar

panels, please wire them in parallel (++ --). Wiring the solar panels in series will void your warranty

and most likely damage the solar charge controller.

When using the CEP200 Black MPPT Charge Controller:

Use any size solar panel, any combination, up to 520W of solar panel input (520W @ 12V DC) If

using multiple solar panels, wiring in series or in parallel is fine as long as the maximum voltage

input is 92V DC.

Parallel Series

• Best for beginners when dealing with solar

power and wind power.

• Allows wiring to remain at a safe, low voltage.

Typically we consider anything under about

30V DC to be “safe”. Of course all electricity

should be respected but the risk of getting hurt

is lower when your voltage is under 30V.

• Requires larger gauge wiring due to low

voltage, which can get expensive.

• Requires longer “parallel” runs of wire which

can be costly and labor intensive.

• Less risk of damaging components due to

lower voltage

• Generally more compatible with mainstream

components.

• For advanced users that are familiar with

Ohm’s Law (see below)

• May be less safe when the resultant voltage

is over 30V DC. 30V DC is widely regarded

as the point at which you will be able to be

shocked at a dangerous level. Especially

high voltages (60+ V DC) can be even more

dangerous.

• Can save time and money by consolidating

all wiring into one single circuit (basically one

wire for all panels)

• Higher risk of damaging

components. Generally as a rule of thumb,

components that can withstand higher

voltages are more expensive.

• Can be a huge advantage because you can

use smaller gauge wire. An easy way to

calculate this is with Ohm’s law

Power (P) = Voltage (V) x Current (A)

5. BATTERY RECOMMENDATIONS

• Battery connection types may vary. As long as the ring terminals are fastened tight (snug)

and cannot accidentally be pulled off the battery, the connection is acceptable.

• Solar generator equipped with battery switches (Rebel, Trailblazer, Scout and Fortress):

turn the knob clockwise. Tighten as much as possible by hand. Not tightening this switch

may cause intermittent issues with solar generator output. If you are experiencing

connection issues, check this switch first. Do not use a hand tool to tighten the battery

switch as overtightening could damage it.

• When wiring batteries in parallel, be sure to use a cutting edge power parallel kit, or

minimum 6AWG wire. If in doubt, it never hurts to add more (or thicker) wires. Adding

more and thicker wires will increase the overall efficiency of your system because the

lower resistance in the wires will produce less waste heat.

• Do not wire batteries in series unless your product specifically instructs you to do so. The

only Cutting Edge Power products that may be wired in series are clearly marked by the

factory at Cutting edge power.

• When connecting the charge controller to batteries, a small initialization spark is typical.

6.2 SAFETY PRECAUTIONS

1. Make sure your battery has enough voltage to register on the charge

controller (8V DC minimum).

2. Make sure you have the right size wire. Wire sizing typically includes 2

considerations:

A. NEC minimum wire size to avoid overheating the wire, based on

insulation material.

The following is an excerpt from the National Electrical Code . It can be used as

a general guideline for wire sizes. Take note of the materials listed

(copper/aluminum) and temperature rating. Many of Cutting Edge Power’s wire

is not included in this table because we use very special, high

temperature/current rated 200°C silicone insulated tinned copper wire.

B. Voltage drop, to avoid low voltage / high current issues.

Voltage drop is a phenomenon that can affect low voltage (under 60V) systems

quite a bit. We recommend checking with the voltage drop calculator from

calculator.net found here. One of the biggest problems with having a voltage

drop too low, is that it proportionally increases the current of the system,

which can have a tendency to overheat wiring or components. You can read

more about this on our blog. As a general rule of thumb, 2% voltage drop is

considered good, and 3% voltage drop is considered acceptable.

When in doubt, bigger wire is better.

Note: the largest practical size wire that can be used in this charge controller’s

terminals is 10AWG. 10AWG silicone insulat- ed tinned copper wire is rated for

140.6A maximum.

3. This charge controller is suitable for charging lead acid 13.7V nominal

batteries (deep cycle, AGM, Gel, SLA) as well as Lithi- um Iron Phosphate

(LiFePO4) 4S 12.8V nominal batteries.

It can be used to charge Nickel Oxide based lithium batteries, but it isn't

recommended because you won’t be able to use the full voltage range of these

batteries.

6.3 How does it work?

MPPT is a fascinating technology. MPPT stands for Maximum power point

tracking. Basically, it is a charging control technique that determines the point

at which a solar panel’s maximum voltage and current (thus, power) can be

used to charge your battery. A visual graph of a typical solar panel is shown

below. The line which follows the “knee” of the curves indicates the maximum

power point. As you can see, the maximum power point will change depending

on the amount of sunlight. The abil- ity of this charge controller to adapt and

harvest the maximum amount of power with any given amount of sunlight is

what makes it almost 99% efficient.

6.6 BUTTON GUIDE

Menu button: short press to scroll through settings. Long press to

modify settings.

Up button: Short and long press does nothing from home

screen. Use to adjust settings after long pressing the

menu button.

Down button: Short press turns on/off the “load” output.

Use to adjust settings after long pressing the menu button.

Long press at home screen to engage or disengage the

“load” function.

6.7 “LOAD” OUTPUT FUNCTION

The load function is typically used for lighting applications, hence the light bulb

icon. It can commonly be set to turn on a load out- put after dusk (when the

charge controller detects 8V or less, it assumes it’s night time). The time aspect

(24h, 1-15h, 0h) is the time the load output will remain engaged. After this time

is elapsed, the load output will be disengaged.

Important: The load voltage settings and time settings must be satisfied in order

for the load output to engage.

6.8 SCREEN GUIDE

Settings that are adjusted will be automatically saved, even if power is

removed.

17

Home Screen:

Default display which shows the battery voltage,

if the solar panels are charging, and if the load

output is engaged.

From the home screen, short press “menu” to view the status of all parameters.

When you get to a setting you want to change, long press “menu” for 3 seconds

to enter “edit mode”. After the setting is adjusted, to save: short press “menu” or

just wait for the screen to time out.

PV OFF:

The voltage at which solar charging will be

disconnected. PV OFF should be the maxi- mum

voltage you want your battery/ batteries to be

charged. (Typ.

Note: this MUST be modified for LiFePO4

batteries!! Refer to your battery specifica- tions!

LOAD ON (Voltage):

The voltage at which the load output will

be engaged (if allowed by time setting).

LOAD OFF:

The voltage at which the load output will be

disconnected. This is a protective setting to

prevent the battery from over- discharging.

LOAD ON (Time):

The time at which the load output can be

engaged. 24h means the load will always be on as

long as the voltage doesn't drop below “LOAD

OFF”. 1-15h means the load output will be

engaged for this many hours after the charge

controller no long- er detects the solar panel

(sunset). 0h activates the “dusk to dawn” setting;

load will be set to engage at dusk and disen- gage

at dawn.

These are preset settings and can be dis- b1, b2, b3, b4

regarded.

The other displays are status indicators/parameters.

7.1 Overview

7.2 Instructions for Use

Cu

rren

t

MPPT (Maximum Power Point Tracking) is an advanced charging method. The MPPT

controller detects the generation power of solar panel in real time and tracks the highest

voltage and current value (VI), allowing the system to charge the battery with maximum

efficiency. Compared to traditional PWM controller, the MPPT controller can maximize the

power of solar panel and thus can provide a larger charging current. In general, the MPPT

controller can improve the energy utilization by 15% -20% compared with the PWM

controller.

Peak voltage (Vpp) of the solar panel is about 17V, while the battery voltage is about 12V.

In general, when the controller is charging the battery, the voltage of solar panel is about

12V and does not fully reach its maximum power. But, MPPT controller can overcome this

problem. It constantly adjusts the input voltage and current of the solar panel to achieve

the maximum input power.

Also, the maximum power point often changes due to different ambient temperature and

lighting conditions. The MPPT controller adjusts the parameters from time to time

according to different conditions, so that the system is always near the maximum

operating point.

MPPT cannot be used alone as a stage of charging. It is usually used to combine boost

charge, floating charge, equalizing charge and other charging methods to charge the

battery.

When the controller starts working, it will make a judgment of the battery voltage. If the

battery voltage is higher than 13.2 V (×2 / 24V), the controller will consider that the

battery is fully charged and will directly enter the floating charge stage without equalizing

charge or boost charge.

When the initial charging voltage of the battery is lower than 13.2V (×2 / 24V), the

charging process is:

MPPT charge – boost charge (equalizing charge) – floating charge, where the equalizing

charge interval is 30 days.

7.2.2 Sleep and wake-up:

Enter sleep:

Press the [OFF] button on the CU remote control or mini remote control. The controller will

turn off all external control devices, and then enters the sleep state of very low power

consumption, to avoid the lithium battery feed caused by not use for a long time;

Wake up from sleep:

1. Press the [ON] button on the CU remote control or mini remote control to wake up

the controller in a sleep state and turn it back to normal work;

2. PV wakeup：

A. If the option [Yes] is selected for the [PV wakeup] function, the controller entering sleep

mode, as connected to a PV panel, will be awakened in the daytime to charge the battery for

more than 30 minutes when the charging conditions are met. The load will be automatically

turned on at night. If the charging time is less than 30 minutes, the lights will not light up at

night, and the controller will continue to sleep;

B. If the option [No] is selected for the [PV wakeup] function, the controller entering sleep

mode, as connected to a PV panel, will be awakened in the daytime to charge the battery

when the charging conditions are met. But at night, the controller will continue to sleep.

(Note: [PV wakeup] function can be selected by CU remote control)

7.2.4 Intelligent power:

The SR-DM200 controller can select an appropriate intelligent power mode according to

the actual battery capacity, the number of rainy days and other factors. Specific intelligent

power modes include: High, Medium, Low, Auto, USE (custom), No (off).

Intelligent power modes:

High - The battery capacity at the starting point of power reduction is high, and the load

lighting time is the longest. This mode is suitable for use in areas with more rainy days or

poor lighting conditions;

Medium - The battery capacity at the starting point of power reduction is moderate, and

the load lighting time is moderate. This mode is suitable for use in scenarios where both

brightness and the number of rainy days are required to be considered;

Low - The battery capacity at the starting point of power reduction is low, and the load

lighting time is the shortest. This mode is suitable for use in scenarios where lighting effect

is highly required;

Intelligent power experiment data

Comparison of intelligent power consumption and the number of rainy days

Intelligent power mode Power consumption per day Number of continuous working days

No 100% 1

Low 50% 2

Medium 25% 4

High 15% 6

Test descriptions: 1. The test battery is fully charged, and loads are consistent in the maximum power and

working time. 2. Assume that the power consumption is 100% when intelligent power mode is turned off. 3. Test result is the data obtained under a single condition (the charge amount is 0 per day).

Actual use may be different from the test condition, and the test result is for reference only.

Auto - High/medium/low intelligent power mode is automatically selected according to the

parameters such as charge amount and power consumption on the day;

For example, in summer, more charge amount is needed, so the controller will run in the

intelligent power mode - low, and lighting effect is better; in winter, however, less charge

amount is needed, so the controller will run in the intelligent power mode - high, and the load

works in a power saving mode, and can keep working in more rainy days.

USE (User-defined) - The user defines the voltage at the starting point of intelligent power

7.2.5 Remote control operation:

Remote control CU-ALL5:

The communication between the controller and the handheld remote control CU-ALL5 can be

operated wirelessly or by IR. Press the [+] and [-] buttons on the remote control to select a

[Remote Control Type] (Infrared/Wireless) for remote operations. In actual use, the infrared

remote control signal is easy to attenuate under outdoor strong light, so the remote

communication distance is 5-6m, and the remote communication distance at night is 8-10m;

the wireless remote control signal can penetrate the plastic housing or aluminum housing,

and the wireless remote control distance can be adjusted in 0.3m to 20m.

7.3 Technical Parameters

● Waterproofing protection

Rating: IP67

● Lithium battery BMS overcharge detection protection

When the controller detects a BMS overcharge protection, it stops charging immediately, preventing the high voltage of PV panel from being applied to both ends of the BMS for a long time, which may cause damage of the battery.

● Lithium battery low temperature charge protection

When ambient temperature drops to the set value, the controller stops charging to protect the lithium battery from an irreversible damage caused by low temperature.

● High temperature protection

When ambient temperature is above the set value, the controller stops charging and discharging to protect the lithium battery from being damaged by excessive temperature.

● Battery reverse polarity protection

When the battery polarity is reversed, the system will not work but it will not burn out the controller.

● PV input end over voltage protection

When the voltage at the PV input end is too high, the controller will automatically shut off PV input.

● PV input end short circuit protection

When the voltage at the PV array input end is short circuited, the controller will turn off charging; after short circuit is removed, charging will automatically recover.

● PV input reverse polarity protection

When the polarity of PV array is reversed, the controller will not be damaged, and normal operation will continue after wiring error is corrected.

● Load power limit protection

When the power of LED lights that customer uses is too large, or the load current is adjusted to be too large, the controller will limit the load power output to less than the rated value, to ensure that the controller and LED load will not be damaged.

● Load overload and short circuit protection

When the number of connected LEDs in series is insufficient (3 or less), the controller will stop output immediately to protect LED loads or controller from damage;

When a short circuit occurs, the controller immediately turns off load output to prevent control damage. After the load short-circuit condition is removed, controller output automatically restores within 1 minute (if it is short-circuited for a long time, output will automatically restore once every 1 hour), or press and hold the test button on the remote control (CU or mini2) for 10S to automatically restore output.

● Load open-circuit protection

If wiring is suddenly disconnected while the LED load is normally running, the controller can immediately turn off load output and protect the controller from damage. After the load wiring is restored, the controller will automatically restore load output within 10 seconds (if the circuit is open for a long time, it will automatically restore output once every 1 hour), or press and hold the test button on the remote control (CU or mini2) for 10S to automatically restore output.

● Night reverse charging protection

Prevent battery discharge through the solar panel at night.

● TVS lightning protection

7.6 Common Exceptions and Handling Methods

"Innovative Renewable Energy Solutions"

OUR STORY

Cutting Edge Power Inc. was founded in 2014 by a father and son in Dallas, TX. Jim and Bobby

are two engineers, still in their prime, who wanted to start a company with two requirements. True

to their engineering spirit, they decided the company had to 1) be related to the latest cutting edge

technology, and 2) only design really cool products!

Jim and Bobby learned that the true key to success would only come by helping other people

achieve their own success. Thus their conclusion was that Cutting Edge Power must

provide Innovative Renewable Energy Solutions to as many customers around the world as

possible. To accomplish this we developed a unique, rigorous design process so that we ALWAYS

remain cutting edge.

We are aware that to participate in this new global economy, companies must be lean, extremely

knowledgeable in their field, and they must be able to produce the highest quality

products. Also, we believe that American companies can still compete in this economy, and

win. Almost all of our products are assembled or fabricated in USA by an exceptionally capable

team of technicians. We are extremely proud of our team of driven individuals.

We're here to stay: Cutting Edge Power Inc. has received zero investor funding, zero government

grants, zero government loans and we do not use crowdfunding sites to develop products. We are

quickly growing but we are not another fly-by-night startup or foreign owned company. We develop

products with our own US-based engineering team with feedback from customers like YOU!

We're the first to admit, independence is an American thing. Wait, maybe it's more of a Texas

thing... Either way, our vision of the future is for everyone in the world to obtain Energy

Independence. In other words, we think electricity should be supplied to a home through an

appliance, NOT from a utility company that pollutes the environment or overcharges and abuses

their customers month after month after month. Not only that, but we find it unacceptable for people

in developing countries to live without electricity.

We won't stop until EVERYONE has Energy Independence!
