This installed system is a 30KvA/3-Phase grid-connected back-up system. The system consists of 3x 48V/10KvA Victron Energy Quattro inverter/chargers, a 250V/100A MPPT, a 48V 40/32 Freedom Won lithium battery, a 10Kva Fronius PV inverter and 36 Jinko solar panels. There is also a generator connected to the second output for when there is insufficient solar and low battery due to extensive usage and grid is not present.
The inverter unit converts the DC voltage from the battery to AC voltage used by standard 230V appliances as well as converting AC voltage from the grid or generator to DC voltage to charge the battery. The inverter/chargers are configured into a 3-phase set up working in conjunction to produce the 3 phases with one acting as master and the other 2 as slave.
There is also a 10KvA Fronius PV inverter which uses solar to provide for the loads during the day with any excess going to help the battery to charge. The system has a solar array which consists of 36 x Jinko 460Wp solar panels which produce an average of 69KWh of energy per day.
12 of the panels are connected to a 250V/100A Victron Energy Smart MPPT solar charger in 3 string of 4 which charges the battery and the remaining 24 are connected to the Fronius inverter in 2 strings of 2 which supplies the loads completely during the day with any excess going to the battery. At night the loads are powered by a 48V 40/32 Freedom Won lithium-ion battery if grid is not available.
The system also has a Cerbo GX remote monitoring unit installed which when connected to an internet connection allows the system to be monitored and controlled remotely by installers and the client via the Victron Energy VRM application.
The Victron Energy equipment has a manufactory warranty of 5 years, the Freedom Won battery has a manufactory warranty of 10 years and the Jinko solar panels have a manufactory warranty of 12 years.
