12v to 24v conversion advice needed

malibuskiermalibuskier Registered Users Posts: 5 ✭✭
I currently have a MS2812 Single Magnum Power Center in a 12v configuration.  I am interested in upgrading the inverter to a MS4024 and upgrading my system to 24v.  Do I need to make any changes to the Power Center itself?  From everything I can find document wise (to my understanding) it should be a simple swap of the inverters.  Am I missing anything here?

    What about your solar array and solar charge controller(s)? You may need to do some rewiring/reconfiguration there.

    The new inverter may have a smaller max breaker size?

    I use power center as all the 'stuff' in front of the house panel, so yes. You will need to change to a 24 volt battery bank, setup your charge controller for charging the 24 volt battery bank, and perhaps reconfigure your array to charge the 24 volt battery bank...
