I want to isolate my 32Amp RV Converter / Charger from the battery system. I’m pulling the charger circuit from the converter but I’m still not convinced my ‘expensive’ battery bank is safe.
I want to put a diode in the line from my 12VDC battery bank to the converter’s 12V fuse panel to prevent any kind of trouble / feedback to my Li-Ion batteries when the converter is on 120VAC and providing 12vdc to the fuse panel.
I’m trying to find a Thru Hole 30 Amp / 12VDC or 15VDC diode in the DigiKey listings and I’m not having any luck? Can someone give me a link?
A little more expensive, but, would it be better to install a relay (with integrated protection) that auto-disconnects the battery bank when the converter is plugged into 120VAC and then reconnects when 120VAC is pulled?
Thanks in advance for your help!
