Hi, I have a multiplus 24/3000/70 connected to lifepo4 battery bank. When testing in my home garage all was working fine when I plugged the ac in for charging.
I have since moved the whole system to my boat which is currently in a boatyard and I haven’t been able to charge the batteries since. I have plugged into the mains at the boatyard, but all I get is a flashing Mains led.
Any ideas?
