    High amperage protection for hot water circuit.

    I am trying to add overload protection to my hot water heating rig. I use the pwm dump load controller from my CC and a solid state relay, 160a crydom. This works amazingly well, dumping 10-20kw of otherwise surplus power to hot water on sunny days. This works great and provides more domestic...

    Lifepo4 ac charging issue

All of this was caused by a bad connection/s at the battery buss bars. The original hardware were 6mm bolts that were too long, I...

    Lifepo4 ac charging issue

    No shore power, totally off grid, but I do have another 10kw generator/welder, that I will try, though it may be a few days before I could move things around in order to run that test. Thanks for your help by the way

    Lifepo4 ac charging issue

    I don't have access to another charger. The charger has no voltage settings aside from a selection of presets, it does have a variable knob for amperage. Turning this down does help, but then were charging at a lower amperage. The charger is picky about the incoming power and will shut off the...
