What backup rating does GW5K-ETA-G20 have?
Rated backup apparent power is 5 kVA. Off-grid maxima are 5.5 kVA continuous and 10.0 kVA for 10 s. Switching time is <4 ms. The 63 A figure is the internal grid bypass, not the off-grid output.
How many MPPTs does GW5K-ETA-G20 have?
3 MPPTs, strings 1/1/1, 21/21/21 A maximum MPPT current and 26/26/26 A short-circuit current. Maximum PV input power is 10 kW. The MPPT window is 120–950 V; at nominal power it is 185~850 V.
Which battery modules stack with this power module?
The ESA battery table names GW5.1-BAT-D-G20, GW8.3-BAT-D-G20, GW5.1-BAT-D-G21, GW8.3-BAT-D-G21, GW6.0-BAT-D-G20 and GW9.0-BAT-D-G20. Up to six modules in one column and twelve in the system. Mixing 5.1/8.3 G20 or G21 with 6.0/9.0 G20 disables battery heating; split expansion needs BMS and DCDC software V06 or later.
