Thanks, 4th D Solar is new to me.
A quick update on my Growatt installation. The Growatt is installed, I wired a disconnects between the Growatt and breaker box and incoming PV panel array, 6 space breaker box, ran 12/2 ROMEX to 3 household outlets, each on its own breaker. The system is grounded and the 4 batteries are in 2S/2P 24V configuration. Only 3 solar panels have been connected to the system provisionally. I still need to build the ground mount.
What we have connected: full size front loader wash machine, 2 full size refrigerator/freezers, 70 pint/day dehumidifier (the hog), 2 sump pumps, and 2 battery tenders for lawn tractor batteries in winter storage. We had all appliances running, and never did it once go over 1100W. The highest load was a little over 30% at one given time. I must admit, the fans got loud, but it is downstairs in the utility room where we can't hear it.
With the dehumidifier running overnight, the batteries were down to 24.1V this morning. Again, with three 320W panels and full sun today, the batteries completely recharged before the clouds moved in around 4:30PM. The 3 panels produced 5.7kWh today. I can't wait to see all six in action.
I talked to our HVAC company, they are going to install a switch that will allow us to select grid or solar operation for our furnace. We are so happy with the Growatt system, that once we get the panel array installed, we are going to expand to a second unit for parallel operation. That will cover almost all of our needs except for A/C, lighting, entertainment and small kitchen appliances. I am happy that our most important needs are covered during outages. It is also going to lower our electric bill somewhat.
