Additional Documentation

Three Ways to Use It

Off-Grid — Run entirely on solar and battery Hybrid — Combine solar, battery, and grid Grid-Tied — Send excess power back to the grid

Common Questions

Can this system send power back to the grid?

Yes — in grid-tied mode, excess solar power can be sold back to the grid. The system also supports pure off-grid operation and a hybrid mode combining solar, battery, and grid.

Can I connect multiple inverters together?

Yes — up to 9 identical SGN11.4KHB-48 inverters can run in parallel for a combined 102.6kW peak system as power needs grow.

What's the actual usable battery capacity?

30.72kWh combined from six 5,120Wh LiFePO₄ batteries in the included enclosed cabinet, each rated for at least 7,000 cycles to 80% capacity and backed by a confirmed 10-year warranty.

Can I add more solar panels later?

Yes — the inverter supports up to 15kW of solar input, well above the 12,600W (28×450W) included in this kit.

Is there a smaller variant available?

Yes — a 20.48kWh / No-panel configuration is also offered on this product's own page as a lower-cost alternative to the 30.72kWh / 28-panel version described here.

Do I need a licensed electrician to install this?

Given the grid-interconnection requirements plus the voltages, currents, and battery wiring involved, installation should be handled by a qualified, licensed electrician familiar with your local code and utility interconnection rules.
