Eco Solar Kits · Sungold Power · SGH-11N3E
A complete hybrid solar system — 11.4kW split-phase inverter with grid-tie capability, 30.72kWh of LiFePO₄ battery storage, and twenty-eight 450W monocrystalline panels.
This all-in-one 12,600W hybrid solar kit is designed to deliver reliable and sustainable power with its robust combination of solar panels, a powerful hybrid inverter, and substantial lithium battery storage. With flexible configuration options, this kit allows you to operate in off-grid, hybrid, or grid-tied modes, providing the versatility to power your home's appliances with solar energy, feed excess power back to the grid, and store energy to help reduce electricity bills or maintain backup power during outages.

Rated output as stated on this product's own specification table — see the note below for a technical caveat on this figure.
Run appliances on solar, send excess to the grid, or store power for backup — one system, three modes.
Three independent trackers supporting up to 600V each, well beyond the 12,600W of panels included here.
Track performance, battery status, and system behavior from your phone or browser.
Parallel up to 9 identical inverters 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.
Mono PERC half-cut cells backed by a 25-year linear product warranty.
