Comments
As SSEGs (small-scale embedded generators) for PV systems are inverter-connected, they are deemed to automatically comply with
Not applicable since electro-mechanical relays are used.
GW10K-DT、GW12K-DT、GW15K-DT are similar with GW17K-DT in circuit and construction except for output rating of current and
Power. The test result can refer to GW17K-DT
