Solis S6-GR1P5K
B4.2 S6-GR1P5K
The 5kW string inverter in the same Solis S6 range, with the highest maximum efficiency on the datasheet, but a G99 application at a 22.7A rated output current (21.7A at 230V).

Our verdict
The same box as the 3.6K with more output: 5kW, a 7.5kW recommended maximum PV input, and 97.7% maximum efficiency, the highest figure on this datasheet. The trade-off is the connection route: rated grid output current is 22.7A at 220V (21.7A at 230V), well over the 16A G98 line, so it needs a G99 application approved before commissioning.
Good
- 97.7% maximum efficiency, the highest in the S6-GR1P range
- Two MPPTs, 7.5kW recommended max PV input
- IP66 enclosure, 12kg
Watch out
- G99 application needed (rated 22.7A at 220V, 21.7A at 230V, over the 16A G98 line)
- No battery port
- Integrated DC switch is optional, not standard
