Entire system is home built and programmed except the inverter which was a surplus rack-mount.
The dump load in the water tank tracks the battery bank voltage, drawing more power as the voltage rises into the float range. This is used to sense available surplus power, which is used to turn on other dump loads, i.e. air conditioning in summer.
I have a couple window units that are cranked to max cooling and come on in sequence as the surplus power rises, on an early summer day with clear skies it can get to the point of needing a sweater in the house :D I’m migrating to a homebuilt multi-stage heat pump this year after the prototype worked quite well last year.
Also seriously considering the ice storage concept for hot nights, though I might need to make an actual ton of ice!
Just made a deal on 8 massive surplus AGM batteries too to refresh my bank

Fucking amazing😮😮 Write a blog if you document things… Might come handy to beginners
