The Grundfos Renewable Solar Inverter (RSI) converts DC power to AC power for pump operation. Designed for continuous/intermittent operation, RSI runs pumps up to 50 horsepower (460 V) in size. The inverter is compatible with new and existing systems, and can operate with submersible or above-ground pumps. With an IP66 enclosure, an extensive range of built-in protection features and operating history memory, RSI is the ideal choice for off-grid pumping needs. grundfos.us/renewables
