Wiring 3 inverters together in parallel to make a 15kw system! These inverters are the Growatt 5000ES model. It has a 5kw inverter putting out 240v AC from a 48v DC battery. This inverter has a built in MPPT solar charge controller that can accept up to 6kw of solar PV per inverter. That means I can have up to 18kw of solar panels connected.
I'm wiring these inverters with a solar-edge auto transformer. This allows me to split the 240v into two 120v legs. This provides the 120/240 volt split-phase power we use in North America.
DIY Powerwall!
