Building a Solar Generator, Powerwall, System for off grid Tiny House on Wheels

This is a complete build of a solar system that will power my friends Tiny House on Wheels. The video shows all the layout, connections, and testing. So make sure to watch to the end if you want to see it fired up and working.

My friend's nick-name is Poet. Poet built his Tiny House on a trailer to it can be towed, THOW. He built it and bought a piece of land completely off grid. There is no grid power available. There is a well on the property that requires 240V AC to power it. Right now, Poet, uses a Honda Generator model EU7000 which can output 120V and 240V split-phase like we use. The well pump is submersible, inside the well. The cord comes out of the well and has a 30 amp twist-lock plug on the end. This is what he plugs into the generator to run his well. This means that in order to have water inside his tiny house, Poet must fire up his generator. This is costly, noisy, and inconvenient.

I'm building Poet a solar power system to handle his needs for the well pump, and a future air conditioner. Below are some of the parts I'm using:

Inverter: I'm using the Growatt SPF 5000 ES model. This inverter has a built-in solar MPPT charge controller (up to 6,000 watts of solar). It can output up to 5000 watts of AC power at 240V 60 hertz. This inverter can also charge the batteries from an AC source, such as his generator. I bought the inverter from Signature Solar.

Auto-Transformer: This device can "split" the 240VAC output into two legs of 120V each. In North America many household appliances run on 120V. This was also bought from Signature Solar.

Update: There is no longer a discount code available.
