I have a phoenix 48/1200 inverter, it was hooked up to lithium lg chem batteries. The low voltage setting was 38v. The inverter kept draining the batteries to 13.7v. They are now garbage. Why did the inverter continue to discharge the batteries when it was programmed to shut off at 38v?
Is the inverter faulty? Does it need to be replaced I don't want to replace 6.75kw of battery for a second time. This was a costly error. The inverter worked well for 2 years.
