GordonT Posted June 22, 2021 Share Posted June 22, 2021 I have two 12v AGM batteries connected in series to give the required output of 24v connected to a 3Kva Expert king inverter tied to the grid with no solar panels. The unit is for backup purposes only. The voltage settings on the inverter are 22 volts min and a 27 volt maximum. As we can go for weeks without a power outage is it necessary to have the inverter charging the batteries even thou the batteries are not being used. My question is should I disconnect the batteries and switch off the inverter for a two or three days a week... Thanks in advance.. Quote Link to comment Share on other sites More sharing options...
Gnome Posted June 25, 2021 Share Posted June 25, 2021 (edited) It keeps the batteries at float. What are you hoping to accomplish by disconnecting it? Edited June 25, 2021 by Gnome Quote Link to comment Share on other sites More sharing options...
