30 kW Three-Phase On-Grid Solar System with Zero Export
For commercial roofs that want to cut the daytime power bill. The meter stops the system sending power back to the grid, which many utilities require when there is no export contract.
Standard kit, supplied complete from China: 64 × 620 W modules, 30 kW inverter, cables and protection. Supplied in the Premium version.
Premium or Value
Same power, two ways to build it. The Premium version uses a Deye hybrid inverter and battery. The Value version uses a MUST off-grid inverter and battery, which costs less but does not send power to the grid.

Frequently asked questions
What is included in the 30 kW 3-phase on-grid solar kit?
64 × 620 W modules (39.68 kWp), a 30 kW inverter and a zero-export meter, PV and AC cable, connectors, and DC and AC protection. Roof mounting is quoted separately once we know the roof type.
Which countries is this 400 V three-phase kit for?
It is built for 380–415 V three-phase supplies at 50 hz or 60 hz, set for your grid before shipment. Typical markets: Shops, farms, schools and small factories in Africa and the Middle East; Commercial roofs in South America, including Argentina; Commercial sites in Asia and Europe. Tell us the country at enquiry and we set the inverter for your grid before shipment.
Is there a cheaper Value version of this kit?
We do not offer a value version at three-phase sizes. The savings are small at this size and the off-grid inverters in the value range are single-phase or split-phase.
How much does it cost?
Send the quantity and destination port and we quote the same day where stock allows. Module prices move with the market, so we do not publish a fixed price for this size.
How is the kit shipped and paid for?
We quote FOB Xiamen or Ningbo, and CFR or CIF to your port on request. Payment is 30% deposit and 70% before loading. Lithium batteries ship as class 9 dangerous goods with UN38.3 and MSDS documents.
Why 64 modules on a 30 kW inverter?
The array is about 1.3 times the inverter rating. The inverter is then at full output for more of the day, and it clips only a little at noon on the best days. We check the string voltage at your coldest morning and the current per MPPT before we fix the design.
