I had Springwell Electrical Ltd install Solar PV and Batteries for me in May 2023. Prior to the install Springwell Electrical has applied for my G99 certificate from the DNO, this was granted prior to the install commencing. The experience was painless and stress free, the week before the installation was due to take place the scaffolding team turned up and put the scaffolding up on the south facing wall, the was over the roof of a first story garage with a sloped roof, there were no issues and no tiles where cracked. As planned, on the Tuesday, Liam turned up just after 8am, unloaded the panels and worked with the other guy to move the panels and rails to the house roof, they spent most of the Tuesday fitting the panels and running the cables to the garage, which is where I wanted the inverter and batteries installed. On the Wednesday, again Liam turned up just after 8am and started running cables from my consumer unit (fuse box) to the Inverter, worked on installing the inverter and connecting up the panels, by about 1pm the panels where connected to the inverter and the house was running on free electricity, only for a short period as it was a test prior to installing the batteries, once the Solar PV test was completed, Liam then installed the x4 5.12kWh FoxESS batteries. At around 15:00, they batteries where all connected up, Liam had set the Inverter up and the house was running on Solar power, which was also charging the batteries, they only required 5% as they turned up charged to 95%. more free electricity. Liam then spent the next hour, connecting the inverter to my wifi, then to the Solis Cloud and showed my how to use and configure the inverter to export to the grid and how to import from the grid when electricity is cheap.
