Full-home battery backup with AC-coupled solar

[@mohamedridhabeldjoudi6261]

Great Work ! I just noticed that the backup panel is installed quite far from the main service panel. Wouldn’t it be easier to place the backup panel next to the MSP since you’re transferring loads? Just curious about the reasoning behind the placement!

The battery cabinet has to be 3' from the window, so not much room to rotate equioment

How do you like this solarstack battery with sol-ark? how it compares to pytes v5 or homegrid in your opinion?

[@SolarEngineering]

I don’t see much difference in the batteries themselves, but there’s a big difference in the cabinets. I like the quality of Stackrack’s cabinets. Disclaimer: I’ve installed two-battery cabinets from both Stackrack and Pytes, and Stackrack has a better technical design. However, I haven’t yet installed a six-battery cabinet from Pytes.
