I’m builiding a battery powered high amperage 12V (13.8V) shack which I can add battery power to in the future. The charger is currently main-powered but there’s no reason I can’t eventually use solar or wind. And I may upgrade the battery type. First I need to prove the basics. And I can take all this portable to deliver up to 100A peaks for up to 5-6 hours operating. Anyway, see what you think. Part 2 and Part 3 coming out soon. You will be seeing more of this system in the future. Callum.
