Pylontech Batteries - MUST Inverter Settings

Recommended Posts

Hi all

I have a MUST 5KVA inverter (Unfortunately no BMS functionality), 2x Pylontech US3000 batteries and 12x Canadian Solar 330W panels.

1. I wanted to find out what one would recommend, for the inverter settings (i.e. charging currents grid/utility, bulk charging voltage, float voltage, low dc cutoff, stop charging voltage when grid available)

2. What settings would I then to need to use to marry my Victon battery monitor (BMV-700)

Thanks

Charging 74A (2x37A) or closest value below this

Bulk: 52.5V

Float: 51.8V

Back to grid voltage: 48V (this is where you need to play around and figure out what works best for you - and ensure that you stay above 20% SOC. The BMV will help you getting the right voltage)

Low cutoff voltage (when your system shuts down): 46V
