I have a Phoenix Inverter 24V 1200VA 120V on my system which has 1kw of solar connected to it with my Lifepo4 batteries, currently just running the fridge in my garage. Is there any option where if the battery gets to a certain level it could switch over to mains power to avoid the fridge turning off, just in case I went several days with no sun where the battery got low? Not sure if that's a feature of the inverter itself or if mine supports that, as this one was pretty much in my budget with anything higher seeming to be overkill.
Alternatively, are there any Victron products like battery chargers, where instead I could have THAT connected to the mains, and when it sees the battery hit a certain voltage or SoC it activates to keep the inverter running? Something like I don't know, if the battery SoC is 30% activate the charger and then stop charging once it's at 50% or something along those lines?
Thanks so much!
