100 A dual battery interface with 30 kVA facility emergency power.

100 A dual battery interface with 30 kVA facility emergency power.

With dual 50 A high-voltage battery ports (200–800 V), the GW30K-ET charges and discharges two independent battery banks at full speed, delivering up to 30 kVA continuous power during utility outages. Two independent 50 A battery ports deliver up to 30 kW continuous DC throughput without external combiner boxes. 30 kVA continuous three-phase backup sustains commercial workshops and critical facility sub-panels in under 10 ms. 100% phase-unbalanced load balancing shifts power dynamically to heavily loaded single-phase tools.

Runs 30000 W AC on three independent MPPTs

Three MPP trackers manage multi-angle commercial solar arrays up to 1000 V DC. The power stage supplies 30000 W continuous three-phase power.

Pairs dual 50 A battery circuits from 200 to 800 V

Two separate 50 A lines connect high-voltage lithium storage. Dual paths distribute current to minimize heat and maximize battery lifespan.

Stands in a 54 kg IP66 commercial enclosure

The 520 x 660 x 220 mm housing protects power components in outdoor conditions. Multi-channel comms include WiFi, 4G, RS485, and CAN.

Technical data

The highest continuous power throughput in GoodWe's compact commercial wall-mount range.

33 kVA maximum AC power throughput paired with 45 kWp DC solar intake.

Engineered for commercial facilities connected to private transformers or in regions without low-voltage feed-in caps, the GW30K-ET pushes up to 33,000 VA of apparent power onto the grid. Its 3 independent 30 A MPPT trackers accommodate modern 600W+ bifacial modules across 6 strings, while dual high-voltage battery ports deliver up to 30 kW continuous storage charging.

01
Project scenario

Commercial & Agricultural Sites with High Grid Capacity (>30 kVA Permitted)

Commercial & Agricultural Sites with High Grid Capacity (>30 kVA Permitted)

Commercial facilities in jurisdictions (or sites with dedicated private transformers) where grid export above 30 kVA is permitted without auxiliary protection penalties.

Delivers full 33.0 kVA peak output (approx. 47.8 A per phase), providing roughly 10% higher continuous power capacity and export revenue than the 29.9 kVA capped model.

Product questions

In what specific scenario should an installer choose the GW30K-ET over the GW29.9K-ET?

When connecting to a private transformer or in regions without the 30 kVA NA-Schutz cutoff. Choose the GW30K-ET when the installation site has an existing central grid protection cabinet, connects to a dedicated private transformer station, or is located in European markets (such as parts of Southern or Eastern Europe) where the 30 kVA NA-Schutz regulation does not apply. The GW30K-ET provides up to 33,000 VA maximum apparent power (approx. 47.8 A per phase), delivering roughly 10% higher continuous power capacity than the 29.9 kVA model.

What size AC breaker and cable cross-section are required for the GW30K-ET?

63 A 3-pole industrial circuit breaker; 16 mm² to 25 mm² copper cable. With a maximum continuous AC output current of 47.8 A per phase, a 3-pole 63 A industrial circuit breaker (MCB/MCCB) is standard. For cable runs up to 30 meters, copper conductors of at least 16 mm² (or 25 mm² for longer runs to minimize voltage drop) are recommended.

Can this model operate in full off-grid backup mode indefinitely if utility power fails?

Yes. Delivers 30,000 VA continuous backup with automated solar black-start. The GW30K-ET provides full 30,000 VA continuous three-phase power on its backup port (with 100% phase-unbalanced load support). When paired with adequate solar PV (up to 45 kWp) and high-capacity battery storage (40–60 kWh+), it will continuously power the facility, automatically black-starting each morning when sunlight returns.
