SAJ 7.5KW Solar Pump Inverter

The SAJ Solar Pump Controller is based on a standard platform controlling a standard 3-Phase asynchronous motor driving a pump powered by a solar array on an option AC generator backup. The SAJ solar controller continuously monitors system performance and incorporates a number of features for pumping system protection in the event of a fault, the SAJ solar pumping system is optimzed for pumping under adverse input power conditions unique to solar arrays. internal diagnostics will tolerate a lower input voltage. Whenever possible, the controller attemps to drive the pump load by maximizing power output from the solar array. SAJ series remote system monitoring a LED display provides a detailed indication of system status.
