My batteries are 2 ultracell 200a each, sealed lead acid. Inverter settings are default, except battery type changed to lead acid. Water pump is 1 HP (750watt). Beside water pump, two air fans, router and Toshiba refrigerator. Refrigerator is @ 300watt.
I bought a Must ups inverter MPPT, VPM 3K
I do have two questions about the device during operation.
1. Charging indicator keeps flashing all the time as the device is operating in AC mode (Powered from Mains). Always Charging batteries!!!. I do have 2 Ultracell 200A batteries.
2. The device gives a short beep as the water pump starts, even when the device is in AC mode (powered from Mains).
