Hi all,
I've got a 48V Lifepo4 bank being charged by two MPP Solar 3048 units in parallel. The whole thing is at a remote off grid location that I don't get to for a few weeks at a time and I'm setting up some remote monitoring stuff.
I'm going to be hooking up a Raspberry Pi running Solar Assistant and a sim-card enabled router to connect the RasPi to the internet. My issue comes in wanting the RasPi and internet to work even if for some reason the BMS or some cells in the battery fails. I've already got one of these 12V Lifepo4 batteries from aliexpress that I only use once or twice a year and only when I'm at said property, so I'd be happy to power my monitoring devices from there. So I have two questions:
1) Can I have this plugged in all the time at full charge without worrying about destroying the 12V battery?
2) Is there a better way to charge this directly from the 48V bank without being crazy expensive? Going through my inverter to charge it with the included 120VAC > 12VDC charger seems silly
I was considering getting a Victron Orion or possibly just a buck converter to save on costs if that would work.
Any thoughts?
