2. Applications
The Grundfos Renewable Solar Inverter (RSI) system is designed for continuous as well as intermittent operation. The system is especially suitable for supplying water in applications such as:
• villages, schools, hospitals, and single-family houses
• farms and ranches, including watering of livestock and irrigation of crops and greenhouses
• game parks and game farms.
The Renewable Solar Inverter (RSI) system can be used in any existing SP pump application, thus providing a very wide range of applications. The only difference is that you use solar panels as the power supply.
Application exampleThe water production of an RSI system depends on the availability of solar power. The result is excess water production in the early afternoon and insufficient water production in the morning and late afternoon. A system equipped with a storage water tank enables stable water supply throughout the day.
One junction box components kit is required for each set of inputs on the DC side. A junction box components kit contains a circuit breaker and surge protection to ensure maximum safety to the user as well as the system.
Install the inverter in an indoor environment/cabinet with sufficient ventilation.

3. Product introduction
Type key
Features and benefits
Maximum power point tracking (MPPT)The inverter has built-in electronics with MPPT function. The inverter will continuously optimise according to the DC input power available.
Overvoltage and undervoltage protectionOvervoltage and undervoltage may occur in case of faulty installation. The inverter will cut out power connection to the motor if the voltage falls outside the allowed voltage limits. The inverter will stay in the same fault mode with the error code displayed on the inverter until the inverter is being reset.
Overload protectionOverload may occur if the maximum allowed frequency is set too high or a wrong pump is used. The inverter will cut out power connection to the motor if overload occurs. The inverter will stay in the same fault mode with the error code displayed on the inverter until the inverter is being reset.
Overcurrent protectionOvercurrent may occur if, for example, a wrong cable size is used. The inverter will cut out power connection to the motor if the current falls outside the allowed current limits. The inverter will stay in the same fault mode with the error code displayed on the inverter until the inverter is being reset.
Note: For the protection to function properly, the actual current value must be adjusted according to the maximum current attained at the maximum frequency shortly after the system started operation.
Overtemperature protectionOvertemperature of the inverter may occur if appropriate ventilation is not available or the ambient temperature is too high. The inverter will cut out power connection to the motor if overtemperature occurs in the inverter. The inverter will stay in the same fault mode with the error code displayed on the inverter until the inverter is being reset.
Note: The inverter does not detect motor temperature or protect the motor against overtemperature.
No-load protectionNo-load situation of the inverter may occur if, for example, the cable to the motor is broken. The inverter will cut out power connection to the motor if no-load occurs. The inverter will stay in the same fault mode with the error code displayed on the inverter until the inverter is being reset.
Note: For the protection to function properly, please check the RSI installation and operating instructions carefully during the operation.
Operation history memoryThe inverter will store historical operating data. The data can be retrieved through the menu on the inverter. Data can be retrieved for every minute of operation up to two years back.

4. System components
An RSI system consists of a standard SP pump, a Renewable Solar Inverter (RSI), ranging from 3 to 9.2 kW, and accessories. The RSI system is configured especially to run with Grundfos SP pumps.
The RSI system components are:
• SP submersible pump, 50 Hz
• Renewable Solar Inverter (RSI)
• junction box components kit, DC
– circuit breaker, DC
– surge protection, DC
• circuit breaker, AC
• solar panel
• dry-running switch
• level switch (optional).
SP submersible pumpThe SP pump is available as complete unit or as separate motor or pump.
SP pump selection for RSI system:
• SP submersible pump, 50 Hz
• power supply: 3 x 380 VAC.
• Material: 1.4301, 1.4401 or 1.4539.
Standard SP pumps can only be operated by AC power supply. Do not connect the SP pump directly to solar panel.
Fig. 3 SP pumps
Renewable Solar Inverter (RSI)RSI is an off-grid solar inverter converting the DC power output from the solar panel to AC power supply for SP pump operation.
The RSI inverter has a built-in MPPT software, protection features as well as operating history memory, see Features and benefits. The maximum power delivered to the motor ranges from 3 to 9.2 kW.
The RSI inverter has either two sets or four sets of power inputs. Each set of inputs has a limit of maximum 750 V and 15 A from the solar panel.
Indoor installation requires ventilation.
Fig. 4 RSI inverter
The RSI inverter combined with controller and protection units can be used for:
• maximum power point tracking (MPPT)
• DC to three-phase AC conversion
• connection to dry-running switch
• connection to level switch
• operating history inquiry.

Circuit breaker, ACAn AC circuit breaker is a standard circuit breaker used for normal three-phase power connection.
Solar panelThe solar panel offered by Grundfos is specially selected for Grundfos renewable products.
All Grundfos solar panels are equipped with plugs and sockets enabling easy connection. The number of solar panels required depends on the water quantity required, water pressure required and installation location.
Dry-running switchThe dry-running switch is recommended for all submersible pump operation. The switch can prevent the risk of the pump operating in a dry well, which could result in damage of the pump.
Junction box components kit, DC
Circuit breaker, DC
Fig. 6 Circuit breaker
The DC circuit breaker is suitable for the solar-powered RSI system.
The circuit breaker enables manual starting and stopping of the system. At least one DC circuit breaker is required for each set of inputs to the RSI inverter. We recommend to install two DC circuit breakers for each set of inputs if the distance between the solar panel and the inverter is more than 10 m. To install the circuit breaker, a torx screwdriver, Tx8, is needed.
Fig. 7 Dimensions [mm], circuit breaker
Surge protection, DC
Fig. 8 Surge protection
The DC surge protection is suitable for the solar-powered RSI system.
The surge protection gives a very safe and reliable protection of the system by having a quick response. At least one DC surge protection is required for each set of inputs to the RSI inverter. We recommend to install two DC surge protections for each set of inputs if the distance between the solar panel and the inverter is more than 10 m.
Fig. 9 Dimensions [mm], surge protection
Level switch (optional)A level switch serves as a start/stop control that depends on the water level in the storage water tank.
