12 kW 3-Phase System

12 kW three‑phase solar kit for near‑commercial use

The 12 kW three‑phase solar kit sits at the boundary between advanced residential and light commercial applications. It is ideal for small companies, office buildings and large private owners who want a serious solar investment.

With 22 panels rated at 500 W and a 12 kW three‑phase inverter, it delivers very high production, covering a large share of daily demand and generating surplus that can be exported to the grid.

Why this system?

For consumption between roughly 420 and 1,120 kWh per month, the 12 kW kit can provide substantial and predictable reductions in electricity spending.

It is especially attractive for businesses with mainly daytime loads, such as offices, workshops or small retail, where most demand overlaps with solar generation.

Surplus energy can be exported to the grid according to current regulations, providing additional revenue or bill credits that further improve the project’s return.

Estimated production and savings

Estimated annual production for this 12 kW system is about 19,800 kWh, making it the most powerful kit in the range.

Components included

The kit includes 22 Tensite 500W TOPCon N‑Type modules, totalling 12 kW of peak PV power. This layout suits warehouse roofs, office buildings and large residential roofs.

The inverter is a Growatt MID 12KTL3-XH 12 kW three‑phase model designed for near‑commercial self‑consumption installations, with the capability to manage high energy flows and advanced monitoring.

The package is supplied with mounting structure for 22 panels, wiring and basic protections, and can be complemented with batteries or other components depending on project requirements.
