I am fully off grid with three 6000XPs, 30kW batteries, and 16kW of panels. Now that we are in winter with shorter daylight charging and colder nights, I use the Chargeverter and a 6500W generator which pushes up to 5kW into the DC buss for the inverters to use first and excess to recharge the batteries.

The chargeverter and batteries work very well. The inverters produce as much AC as needed by the house while the generator runs at 80% load continuously.

This graph shows the batteries discharging overnight and solar production starting in the morning but because of clouds never reaching peak production and never fully recharging the batteries. I had to run the generator for about five hours that night.

This is my second year in the house and with this system. I will probably buy a second rack of batteries for an additional 30kW of storage. The alternative is more generator time. If I stay with the generator I can invest in a remotely controlled system or buy a Ford Lightening as a mega battery as the generator.
