Asymmetric high-current stringing with 60 kVA motor starting surge.
Featuring asymmetric high-current MPPTs (42 A / 32 A / 42 A, Isc 55 A / 42 A / 55 A), it handles modern 600W+ bifacial panels on main warehouse planes while accommodating smaller canopy sections without current clipping. 3 MPPT channels optimize 6 strings of high-power bifacial modules without thermal current throttling. 60,000 VA apparent power surge tolerance (10 seconds) effortlessly starts heavy industrial inductive loads. Wide MPPT window down to 165 V starting threshold extends daily solar harvesting hours.
Takes 42 A and 32 A string inputs
Three MPPTs accommodate 42 A, 32 A, and 42 A maximum currents. Two strings connect to each tracker with 55 A and 42 A short-circuit tolerances.
Pairs 200 to 800 V high-voltage storage
One dedicated high-voltage battery port operates from 200 to 800 V DC with a 500 V nominal rating. CAN protocol ensures continuous BMS coordination.
Stands up to harsh industrial environments
An IP66 die-cast enclosure and intelligent fan cooling maintain 98.1 percent peak efficiency. The 62 kg unit operates in ambient temperatures from minus 35 to 60 C.
Technical data
Driving heavy commercial battery banks with high-current string flexibility and motor starting capacity.
100 A high-rate battery throughput with 60 kWp solar absorption.
Standard 20–30 kW commercial inverters max out at 50 A battery throughput, limiting rapid energy storage on short winter days. The GW40K-ET-10 delivers full 100 A continuous battery throughput across a 200–800 V window, allowing facilities to charge and discharge a 100+ kWh battery bank (such as GoodWe Lynx C) at full 40 kW continuous power.

Project fit
Where this model fits.
Scenarios that show which projects the GoodWe GW40K-ET-10 belongs in, what to verify before quoting, and when another model is the better pick.
Commercial Manufacturing & Cold Storage with 50–60 kWp Solar & 100 kWh+ Battery

Facilities with continuous heavy daytime baseline loads (refrigeration compressors, automated packaging lines, HVAC chillers) demanding high-current battery throughput.
A 100 A battery connection allows rapid charging of a 100 kWh Lynx C rack during cheap 2-hour midday solar peaks, discharging at full 40 kW during expensive afternoon utility demand windows.
- BoundaryIf total solar PV is under 45 kWp, battery capacity is under 50 kWh, and wall space accommodates a 54 kg chassis instead of the 70 kg industrial enclosure, step down to the GW30K-ET.
- If total solar PV is under 45 kWp, battery capacity is under 50 kWh, and wall space accommodates a 54 kg chassis instead of the 70 kg industrial enclosure, step down to the GW30K-ET.
Commercial Facilities with Heavy Inductive Motors & Whole-Site Backup

Facilities running large three-phase hydraulic pumps or industrial compressors that experience severe startup inrush spikes.
When paired with the GoodWe GW125K-STS-G10 static transfer switch, it delivers 40 kVA continuous emergency power with a massive 60 kVA (10s) starting surge to ride through motor starts without tripping.

GoodWe ET50 Series 40-50 kW datasheet (EMEA, EN)Product questions
Is an external Static Transfer Switch (STS) required to enable backup power on the GW40K-ET-10?
Yes. The GoodWe GW125K-STS-G10 is required for automatic whole-facility transfer. For automatic on-grid to off-grid backup transition across the facility's main AC distribution board, the external GoodWe GW125K-STS-G10 switch is required. While the inverter houses internal off-grid generating capability, the STS box provides the motorized, utility-grade isolation contactors necessary to safely switch 40–125 kVA commercial circuits without back-feeding the grid.
Why are the MPPT input currents specified as asymmetric (42 A / 32 A / 42 A)?
To allow flexible stringing across major warehouse roofs and smaller canopy sections. * MPPT 1 & MPPT 3 (42 A / Isc 55 A): Dual-string channels designed for large parallel strings of modern high-current 600W+ bifacial panels on the main roof planes. * MPPT 2 (32 A / Isc 42 A): Medium-capacity channel designed for a smaller roof pitch, dormer, or carport section.
What battery systems are natively compatible with this 100 A port?
Commercial high-voltage battery racks (e.g., GoodWe Lynx C or BAT-C). The GW40K-ET-10 is optimized for commercial high-voltage battery systems operating between 200 V and 800 V, including GoodWe Lynx C indoor battery racks (LXC101 to LXC156) and GoodWe BAT-C outdoor storage cabinets. Residential 25 A battery stacks (like Lynx Home F) will artificially bottleneck the inverter's charging throughput.
What size AC circuit breaker and cable cross-section are required for installation?
80 A or 100 A 3-pole industrial MCCB; 25 mm² to 35 mm² copper conductors. The inverter has a maximum continuous AC output current of 60.6 A per phase (at 380/400 V). A 3-pole 80 A or 100 A industrial circuit breaker (MCCB) is required, paired with copper conductor cross-sections of 25 mm² to 35 mm² depending on run length to minimize voltage drop.
