SA: NRS-097-2-1 Certified and CoCT Approved.
UK: G99 Certified.
Important
Please note that this inverter does not include a data logger, CT, meter or export power manager. The meter "SOL-METER-3PH-CT3" is needed for export power control of one inverter, for more than one inverter use the EPM3-5G-PLUS. The meter requires a data logging stick but EPM3-5G-PLUS has a built in data logger. These items are sold separately.40 kW essentials
The most powerful inverter in the 37 kg S5-GC 25–40 kW case. It can run 60 kW of panels, so it suits larger commercial roofs where one inverter should do the work.
Filling 60 kW of PV
Four MPPTs each take two strings, 32 A combined per tracker and 50 A short-circuit. The window is 200–1,000 V, with start-up at 180 V and 1,100 V as the absolute limit. Solis quotes a DC/AC ratio over 150% for the range. One route to 60 kW is 120 panels of 500 W as eight strings of fifteen, after a cold-weather voltage check.
Features and exclusions
- DC switch built in
- Surge protection, Type II on DC and AC
- Smart I-V curve scan and string monitoring
- AFCI fire-risk protection, activated at commissioning
- Export control hardware (meter or EPM)
- Data logging stick
Grid connection
Rated output current is 57.7 A per phase at 400 V, with a 66.9 A maximum. Confirm the supply can carry it and submit the G99 application first. Certificates, including the G99 Form A2-3 for 40 kW, are in the Documents tab.
Add for this install
-
Solis export meter, three-phase
Meter plus three 150 A:5 A CTs. The supplier notes name it for export control of one inverter.
-
Wi-Fi and LAN logger
A 4-pin stick that can use a wired LAN connection, often steadier than Wi-Fi in a plant room.
-
Warranty extension to 20 years
Covers the 25, 30, 36 and 40 kW S5 models, this one included.
