Off grid battery charging for small mine

[Mike90250]

Harbor freight has a small generator, you could get 2 of them, (assume 1 will break) and power a 3 stage charger and use that to "bulk" the battery. Then use 1 solar Panel to "finish off" the absorb and float part of the charge cycle. You could keep the generator run time down to likely less than 2 hours in the morning, and use solar the rest of the day.

And you have to cobble up a mount, to attach and aim the solar panels with.

Thanks so much for this information, I really appreciate it. In your opinion what would my best bet be? .

Until I get a firm number of how many watt hours per day you need the months I cannot answer.

Based on a $750 budget I can tell you about all you can do is have a system that will generate roughly 200 to 400 watt hours per day. That is not much power. In 12 volt battery amp hour terms is 17 to 34 amp hours per day.
