48V Split Phase Hybrid Solar Inverter · SGN-11K15PRO
When the grid goes down, your home shouldn't. The SGN-11K15PRO is a 48V split-phase hybrid solar inverter built to keep an entire household running — air conditioning, well pumps, EV chargers, and everything in between — with 11.4kW of continuous output and true 200A whole-home backup, so there's no sub-panel to plan around.
Whether you're designing an off-grid cabin system, a grid-tied setup that sells power back to the utility, or a hybrid system that blends solar, battery, and grid seamlessly, the SGN-11K15PRO adapts to the job. It converts solar energy into usable AC power, banks the surplus in your battery bank, and automatically shifts between sources so the loads in your home never notice the difference.
At the center of that flexibility is a 48V battery architecture that works with lithium (LiFePO4) or lead-acid banks, giving installers room to spec the storage that fits the budget and the site.
Most backup inverters force a choice: power a few "critical" circuits, or install a second panel just to get whole-home coverage. The SGN-11K15PRO's integrated 200A load breaker is sized to match a standard residential service, so it can back up the entire panel directly — HVAC, kitchen appliances, and all — without rewiring circuits into a smaller backup subset. When the grid drops, the transition to battery and solar power happens automatically.
Three independent MPPT charge controllers, each rated for up to 600V, let the SGN-11K15PRO pull in up to 15,000W of PV capacity across separate strings or roof orientations. A wide 70V–540V MPPT operating range and 90V startup voltage mean the inverter starts harvesting early in the morning and keeps tracking efficiently even as panel output drifts through the day — translating to more usable kilowatt-hours per array, not just a bigger spec sheet number.
Homes and small commercial sites don't always stay the same size. Up to 9 SGN-11K15PRO units can be paralleled together, scaling a single-inverter install into a 102.6kW system without swapping out the core hardware. That makes it a practical choice for installers who want one SKU to cover both a modest residential retrofit and a much larger energy project down the line.
An IP65-rated enclosure means the SGN-11K15PRO doesn't need a dedicated equipment room. Mount it in a garage, a utility closet, or directly on an exterior wall, and it's built to shrug off dust, rain, and everyday weather exposure. Integrated DC and AC Type II surge arresters add a layer of protection against the electrical surges that come with storms and grid fluctuations.

No. It outputs native 120/240V split-phase power directly, so no additional step-up transformer is required for standard residential loads.
Yes. The inverter supports full hybrid operation, drawing from solar, battery, and grid sources simultaneously and switching between them intelligently based on availability and priority settings.
Yes. A dry contact port supports connection to compatible generator auto-start controls for backup power during extended outages.
Installation should be performed by a licensed professional, though the inverter ships with mounting hardware, wiring terminals, and Wi-Fi setup to streamline the process.
