This is a small commercial size: workshops, farms, schools and larger homes on three-phase. It runs up to 22.5 kW of PV from a 15 kW rating.
Laying out 22.5 kW
The recommended PV is 1.5 times the rating. Two trackers take 32 A each (40 A short-circuit), with two string inputs apiece. Forty-five 500 W modules make 22.5 kW. Four strings of eleven (22 kW) is an even split, one pair per tracker. Tracking covers 160–1,000 V and the absolute input limit is 1,100 V.
Supplied and required
- Integrated DC switch
- DC and AC surge protection, Type II
- DC arc-fault detection, activated on commissioning
- Three-phase meter, for export limiting
- Data logging stick
G99 connection
At 21.7 A rated per phase it is well beyond G98. Submit the G99 application with the certificates from the Documents tab. If the DNO offers a lower export limit, the G100 certificate covers a meter-based limit.
