> do you need to to become a mad-scientist electrician and DIY?
I did my own a couple years ago, and it worked quite well on the first go. I got someone else to build the LiFePo4 battery pack (16 CATL cells for 48v with a JK BMS).
It was fairly easy to build. Mount panels on the roof, and wire everything (PV, battery, grid electricity if you want it, and the output) to the inverter. I added some extra steps to monitor usage and output, and a smart MCB. I also have a small shop that I can feed from solar power if the battery is almost charged and the sunset time hasn't reached yet.
See if you quotation is to export electricity to the grid. Those kinds of setups usually require a certified company to do the installation (to make sure the inverter syncs with the grid), but for off-grid setups, you can definitely DIY.
