Why did you go with SolarEdge instead of Victron? And where did you and how did you source those batteries? I have been interested in trying to build my own battery. I am confident I could do it, just curious.
Hey Sean,
The SolarEdge system i already had installed for 5 years, if i had to choose again to build from scratch, i would have chosen for DC coupled system from Victron. Unles your roofing areas are situated in shaded suroundings, than the optimiser system of SolarEdge has a better efficiency.
LiFePO4 battery system DIY you can purchase in China, i chosen for the AliExpress shop named BatteryQueen, they sell complete DIY kits with brand new and certified SEPLOS-BMS/EVA-cells products. Be aware for shops that sell cheaper cells without QR-code traceable production certificate (old electric cells from China citybusses) Always ask for a statement that cells are brand new.
Upgraded the Cerbo GX to version 3.60 and expanded the DC wiring for with the SmartShunt-300A for the additional SEPLOS unit (still awaiting to arrive) Built in 2 small coolingfans in the control cabinet, temperature control by Cerbo relais 1
For these 12vdc fans a buck-boost converter 60vdc to 12vdc is mounted and now also provides the power for the Cerbo.
