AES LiFePO4 batteries are SAFE and will PERFORM BETTER than the
lead acid battery you’re installing today
JUCE© Enhanced Run Time
AES LiFePO4 100% DoD battery ratings represent the
actual usable energy output available from a fully charged battery.
Lead-acid batteries for deep cycle solar applications are designed for 50% DoD, or less.
AES LiFePO4 will deliver a minimum 2x run-time and energy output over lead-acid
battery banks of the same capacity.
Installers will have to PURCHASE and INSTALL 2x the lead acid battery
capacity to match AES LifePO4 with 100% DoD. JUCE©

2. PEAK AC SURGE: Convert Inverter AC Surge to DC Amp and Divide by 300 A = Number of Batteries
3. CONTINUOUS AC: Convert Inverter AC Continuous to DC Amp and Divide by 130 A = Number of Batteries
4. FULL CHARGING: Divide Inverter Continuous Charge DC Amp by 130 A = Number of Batteries

Off-grid Lead Acid Replacement
In May 2017, the Auerbachs decided to upgrade their thirteen
year old Lead Acid batteries to lithium batteries seeking better
charging and discharging efficiency. Their batteries were
replaced with Discover AES LiFePO batteries with over 95%
two-way efficiency. It didn’t take them long to notice the
increase in efficiency. “We ran the generator for a total of 90
hours, a shade under one hour per day.” In past years, the
system would require the generator to run for 4 - 6 hours
every second or third day.“
Off Grid
Off-Grid Remote Water Pump Station Water is a vital resource for any community. In the aftermath of hurricane Maria, many remote water systems in Puerto
Rico failed because of a lack of power. Many are now being reconfigured with the assistance of the American Red Cross and
Water Mission. Pump and filtration systems are being backed up with off-grid solar systems so as to be able to ride out
future severe weather and consequential power interruptions. Critical to the design is a highly efficient solar system
supported by a single AES battery utilizing LYNK closed-loop network communication to optimize dynamic charging
capability of the Inverter Charger and MPPT 60 charge controller. Plug-and-play LYNK network communication and a
straight forward battery cable installation, the same as a lead acid battery, make the AES LiFePO4 battery the preferred
choice for installers in remote locations.
Application
• Micro grid power for community water pump
and filtration station
Requirement
• Backup power, high efficiency charging, solar
/ electrical system
System
• 1x AES 42-28-6650

Whole Home Battery Backup
Whole Home Battery Backup – Self ConsumptionAfter investing in a sophisticated grid interactive inverter charger system to support
advanced self-consumption the home owner became frustrated with the installed lithium
batteries that did not report state of charge (SoC) or available capacity to the system. The
local installer came to the rescue by installing five Discover AES LiFePO Batteries with LYNK
technology. AES LYNK technology now provides real time closed-loop communication with
the Xanbus enabled XW+ inverter chargers. Not only can the home owner now easily
monitor SoC, available store energy and daily energy throughput, but AES LYNK is also
improving system performance with faster recharge times.
Application
• Grid-tie whole home backup and self-
consumption
Requirement
• Upgrade from old lithium to advanced LiFePO
able to communicate status
System
• 5x AES 42-48-6650 (33 kWh)
• 2x XW+ Inverter Charger
• 2x MPPT 80

Micro-Grid / Diesel Abatement
Micro-Grid / Diesel Abatement – Remote School
School District 27 and Naghtaneqed Elem-Jr Secondary were looking to reduce
their ~$78,000 CAD annual diesel fuel bill to provide power to a remote school
and out-buildings. To reduce off-season diesel consumption, the contractor
reconfigured the school’s system, adding a containerized 3PH hybrid solar
system supported by eighteen AES batteries in parallel. Taking advantage of
RUSH, RAPI-CHARGE and PARALLEL POWER technology the School District
estimates saving $50,000 CAD a year in diesel costs.
Application
• Diesel abatement – remote public school
Requirement
• Reduce diesel consumption, power for school, wood
shop, three mobile home and a health unit.
System
• 18x AES 42-48-6650 (120 kWh)
• 6x SMA Sunny Island Inverter Charger
