Hi. A solar pumping system has been installed in my facility for demo purpose. The system consist of the following main components:
- 10 solar modules, @ 50 Wp, Vmp 17.5 V, Imp 2.9 A, all connected in series,
- Charger controller + MPPT 45 Amps,
- Four 12V batteries (not deep cycle batts.) connected in series, system voltage 48 Volts,
- a 48 V/1200 Watt pure sinewave inverter,
- A submersible water pump, 260 Watts.
The inverter's alarm is activated for about 30 seconds each time the pump started. From the inverter specification, it activates the alarm when the battery voltage goes down to 43.6 Volts.
Question: why is the alarm activated and what would be the risks and solution.
Thank you.
