More information
The S5-GR3P20K is the largest inverter in this group: 20 kW rated, 22 kW maximum, with a recommended array of up to 30 kW. Each of its two MPPTs takes 32 A, with up to four strings in total. Rated grid current is 28.9 A at 400 V, or 30.4 A at 380 V, so cables, breakers and the supply connection need sizing for it.
Check the grid connection rules for a 20 kW system with your electricity distributor before ordering. The inverter is grid-tied only: it has no battery input and stops when the grid does. Its protection list covers DC reverse polarity, short circuit, output overcurrent, surge, grid monitoring, islanding and temperature, and AFCI 2.0 is available as an option. Monitoring is over RS485 or an optional Wi-Fi or GPRS module with the SolisCloud app.
SOLAR24's own engineers survey the site, size the system and install it. Installation by our engineers includes 2 years of free service, and we help customers claim the manufacturer's 5-year warranty if a fault appears. We also handle the net metering paperwork for systems that qualify.
