Back up Solar Generator for home.

My attempt to make a backup solar generator for power outages for my home.
I currently have an 8 kva generator hard wired into my house. The longest power outage I experienced due to storms has been 3 days. The solar generator is to keep my fridges and freezer running plus phones/tablets. This way I don't have the generator running around the clock except at peak times preparing meals. This reduces the hassle of storing large quantities of generator fuel that can sit for long periods as there is no local fuel depot where I live.
The system works better than I expected. I now run my fridges and freezer full time, saving power.
I added an automatic transfer switch to switch back to mains power or generator power when there is no sun for long periods.
I would recommend installing a RCD duo earth leakage protection for peace of mind as I have the same installed in my Camper van battery /inverter system. Link below for RCD.
