FAQ
Does the inverter turn off when the low battery warning is triggered, or does it continue to invert?
If the inverter is connected to AC input, it will start charging the battery when the low battery alarm is triggered until the voltage returns to an acceptable range. If not connected to AC input, the alarm activates when the battery voltage reaches 21V, and the inverter will shut down at 20V.
Will it work with lithium batteries?
Yes, it is compatible with lithium batteries, provided they are 24V.
Should I use a BMS (Battery Management System) with my LiFePO4 batteries and this charger?
Typically, LiFePO4 batteries come with a built-in BMS, so an additional BMS is not necessary.
