Description
Multi-pitch commercial tracking without DC optimizers.
GoodWe GW25K-ET is a 25 kW commercial three-phase hybrid inverter with 3 independent MPPT trackers and dual 50 A high-voltage battery ports, engineered to optimize complex multi-pitch warehouse roofs and dual-column storage.
3 Independent 30 A MPPT Trackers
Eliminates string mismatch across East, South, and West commercial roof pitches (6 strings total).
Dual 50 A High-Voltage Battery Ports
Connects two separate battery towers directly without external DC combiner boxes (100 A combined).
25 kVA Continuous Three-Phase Backup
Delivers full emergency power to commercial HVAC, ventilation, and machinery during outages.
100% Phase Unbalanced Output
Dynamically diverts power to heavily loaded single-phase circuits to eliminate peak demand charges.
More product details
Sprawling commercial roofs with 3 distinct pitch orientations suffer severe mismatch losses if combined on fewer trackers. The GW25K-ET provides 3 independent 30 A MPPT trackers (Isc 38 A), optimizing power from 6 strings of modern 600W+ bifacial modules.
- 3 MPPT channels allow dedicated tracking for East, South, and West warehouse pitches with zero inter-string clipping.
- Accepts up to 37,500 W of solar generation, routing daytime power directly to building machinery and dual battery banks.
- Wide MPPT window (200–850 V) maintains peak conversion efficiency across extreme summer and winter string voltages.

Dual-tower battery integration with 25 kVA emergency power.
Connecting large battery capacity (40–60 kWh) typically requires either dangerously tall single columns or expensive external combiner switchgear. The GW25K-ET features dual independent 50 A battery ports to plug two floor stacks directly into the inverter. Two independent 50 A battery ports deliver up to 50 kW combined DC throughput across a 200–800 V window. 25 kVA continuous three-phase backup sustains commercial workshops and critical facility sub-panels in under 10 ms. 100% phase-unbalanced load balancing shifts power to heavy single-phase tools without pulling grid electricity.
Takes 37500 W PV on three 30 A trackers
Three trackers manage six strings in a 2/2/2 layout with 30 A per MPPT and 38 A short-circuit current. Operating range spans 200 to 850 V.
Holds 25000 VA backup and 30000 VA surge
The backup stage maintains 25000 VA continuous three-phase output off-grid. Overload capacity supports 30000 VA for 60 seconds to start inductive loads.
Pairs two battery inputs from 200 to 800 V
Two high-voltage Li-Ion inputs operate across a 200 to 800 V window. Smart fan cooling regulates the IP66 chassis from minus 35 to plus 60 C.
Technical data
Consolidating multi-orientation solar arrays and dual-tower storage into one high-power chassis.
3 MPPTs across 6 strings with dual independent 50 A battery ports.
Rather than deploying multiple smaller inverters with separate battery ports, the GW25K-ET accepts up to 37,500 W of solar input across 3 trackers (2 strings per MPPT). Its dual battery inputs allow commercial facilities to connect two independent high-voltage battery banks (up to 50 kW combined charge power), eliminating external DC combiner hardware and installation complexity.

Complex Commercial Rooftops with 3 Distinct Pitches (30–38 kWp PV)
Commercial warehouses, logistics centers, or agricultural facilities with East, South, and West roof sections.
Grouping 3 orientations into 2 MPPTs forces parallel mismatch losses. The GW25K-ET’s 3 independent MPPTs (6 strings) allow dedicated tracking for each roof aspect without requiring expensive DC optimizers.
- BoundaryIf the roof has only 1 or 2 pitches and total array size is under 30 kWp, step down to the GW20K-ET to save capital cost.
- If the roof has only 1 or 2 pitches and total array size is under 30 kWp, step down to the GW20K-ET to save capital cost.
Facilities Requiring Dual-Tower High-Voltage Battery Storage (30–60 kWh Total)
Projects installing 30–60 kWh of storage to achieve high self-consumption and extended multi-hour emergency backup.
Allows connecting two separate battery stacks (e.g., two 20 kWh Lynx D towers) directly into dedicated inverter ports without purchasing external DC combiner switchgear.

GoodWe ET 15-30kW Series datasheet (EN) GoodWe ET Series 15-30kW Datasheet (EN) GoodWe Lynx-D Datasheet (EN)Product questions
Why are dual battery ports advantageous over a single battery port on a 25 kW inverter?
Eliminates external DC combiner boxes and avoids dangerously tall single stacks. Connecting large battery capacity (e.g., 40–50 kWh) to a single battery port requires either very tall single-column stacks (structural height and seismic risk) or an external parallel combiner box with DC fuses. The GW25K-ET’s dual battery ports (Port A and Port B) allow two independent, manageable floor stacks to plug directly into the inverter with dedicated internal fusing and 50 A charging per port.
Do the two battery towers connected to Port A and Port B have to be identical?
Yes. Both battery towers must use identical module counts and chemistry. Both ports share an internal DC bus architecture. For balanced operation and safe current distribution: * Both towers must have the same nominal voltage, identical module counts, and same cell chemistry. * *Do not mix*: A 3-module tower on Port A with a 5-module tower on Port B.
What is the maximum continuous AC export current on this model?
39.9 A max output current; 50 A or 63 A 3-pole industrial circuit breaker. * Nominal Output Current: Approx. 36.2 A per phase at 400 V three-phase. * Maximum Output Current: 39.9 A per phase (27,500 VA apparent power limit). * Breaker Recommendation: A 3-pole 50 A or 63 A industrial circuit breaker (MCB/MCCB) on the main AC distribution panel.
