If the PurePro has no output, check the following:
- The battery voltage is too low. Recharge or replace the battery.
- The load current is too high, and part of the load is turned off to restart the inverter. Reduce the load current into the PurePro.
- The PurePro is overheated and is undergoing thermal protection. Allow the PurePro to cool for a while and place it in a well-ventilated area.
- The terminals are reversed. Connect the positives and negatives to the correct DC terminals.
- The RCD has detected earth leakage and has disconnected the loads.
