Eco Solar Kits · Sungold Power · SGH-11N5E
A complete hybrid solar system — dual split-phase inverters (20kW continuous, 22.8kW peak combined) with grid-tie capability, 51.2kWh of LiFePO₄ battery storage, and thirty-six 450W monocrystalline panels.
This Hybrid Solar Kit comes complete with 16,200W of solar panels, 2 x 11.4kW hybrid inverters, and a massive 51.2kWh lithium battery bank.

Two inverters paralleled, each rated 10kW continuous with an 11.4kW peak, for motor starts and other high-draw moments.
Run appliances on solar, send excess to the grid, or store power for backup — one system, three modes.
Two inverters, three MPPT trackers each rated 15kW per unit, supporting up to 600V per tracker — well beyond the 16,200W of panels included here.
Track performance, battery status, and system behavior from your phone or browser.
Beyond the 2 inverters included, parallel up to 9 total for a 102.6kW peak system as power needs grow.
Meets utility-interconnection standards for grid-tie use, in a rated-for-outdoor enclosure.
Confirmed directly for this inverter model — notably longer than the off-grid SPH-series inverters.
182mm Grade-A monocrystalline cells backed by a 25-year linear product warranty.

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.
Yes — beyond the 2 inverters included, up to 9 identical SGN11.4KHB-48 inverters can run in parallel for a combined 102.6kW peak system as power needs grow further.
51.2kWh combined from ten 5,120Wh LiFePO₄ batteries across 2 included enclosed cabinets, each rated for at least 7,000 cycles to 80% capacity and backed by a confirmed 10-year warranty.
Yes — the two inverters combined support up to 30kW of solar input, well above the 16,200W (36×450W) included in this kit.
Yes — this product is also available without panels, for anyone sourcing their own or already owning compatible panels.
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.
