Solis S6-GR1P5K
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.
