I had a 6kw generator that I used to charge my batteries through my easy solar and had no problems at all, then the generator broke down so not having much spare cash I purchased a 1.1kw generator wired it up and it started to charge but the generator wasn't able to provide enough power so it cut out, then after saving up I bought a new 5.5kw generator wired it up and my easy solar tried to charge but nothing happened can someone advise me please
