For an isolated villa in the area of Sombor Serbia the client installed a small solar system. It runs a vital heating system, but experienced problems to get through the dark and cold winter. Also, peak loads were too close to the previously installed inverter. Independent Energy redesigned the system, installed a Victron Quattro 48/8000 and implemented a Victron Color Control that enables remote monitoring and auto starts the generator if needed. The system is up and running for years now to full satisfaction.
