Using 48 volt charger while batteries wired to inverter

[Kent86]

I just received the EG4 18 amp 48 volt charger. Is it safe to charge the two EG4 Lifepower batteries from an exterior source (the new 48 volt charger) while the inverter (EG4 3000) is operating or should I disconnect the batteries from the inverter to charge them? I'll only use the new battery charger plugged into a Bluetti and in rare circumstances when solar isn't enough and grid is down, but just want to see if anyone has experience with this.

Yes.

Multiple charging sources are generally not an issue.

Go forth and be merry.

I charge 48V batteries with an external charger while the battery power is being inverted to 120VAC every day, sometimes twice a day. A key assumption is that your battery charger won't charge the batteries to a voltage that won't be accepted by the inverter, i.e. will cause the inverter to shut down. My guess is that this is something you don't need to worry about.

I appreciate everyone's input, thank you!
