Never Lose Power When the Grid Goes Down

Never Lose Power When the Grid Goes Down

Most grid-tied solar systems sold by big installers go completely dark the moment the utility fails — defeating the entire purpose of investing in solar. The SunGoldPower 11.4kW inverter operates as a true hybrid, keeping your 240V split-phase loads running on battery and solar regardless of grid status. The integrated APS transmitter enables seamless 200A whole-home backup transfer. At Off Grid Vault, every component we carry is vetted to work together — this inverter is no exception, specced to integrate cleanly into systems we would build for our own cabins.

Maximize Your Solar Harvest With 18,240W PV Input

Maximize Your Solar Harvest With 18,240W PV Input

Four built-in MPPT controllers handle up to 18,240W of PV input at voltages reaching 600V. This high-voltage architecture lets you run longer string configurations with thinner wire runs and reduced line losses — a meaningful advantage on larger homestead or cabin installations where panels sit far from the power center. The 80-550V MPPT range ensures you capture usable energy even in low-light conditions. For anyone sizing a serious off-grid build, this input capacity means fewer charge controllers and a cleaner wiring layout.

Scale From 11.4kW to 34.2kW Without Starting Over

Scale From 11.4kW to 34.2kW Without Starting Over

Support for up to three parallel inverters means your system grows with your power needs. Start with a single 11.4kW unit covering your core loads — well pump, refrigerator, lighting — then add units as you expand a workshop, add outbuildings, or increase daily consumption. The cloud platform provides remote troubleshooting and firmware updates, so you can monitor and manage the system without climbing into a power shed. An integrated rapid shutdown device keeps the installation compliant with safety standards. This inverter is built to adapt, not become obsolete.

System Compatibility Check

Verify these three conditions before integrating this inverter into your build.

  • Battery bank voltage falls within 120V–500V range
  • Total PV array input does not exceed 18,240W
  • AC input voltage stays within 211V–264V range

“Replaced a grid-tied inverter that went dead during a 3-day outage. This SunGoldPower unit kept my well pump, fridge, and lights running the entire time on battery and solar. The APS transmitter made the backup transfer seamless. Off Grid Vault's team helped me spec the right battery bank for my 22 kWh/day consumption. Finally feels like a real off-grid setup.”

Frequently Asked Questions

If you are currently paying $250/month to the utility, this inverter becomes the core of a system that eliminates that bill. A complete solar and battery build centered on this unit typically pays for itself in 3.3 to 5 years depending on your consumption and solar resource. After that, every dollar stays with you. This is an investment with a calculable return, and the 10-year warranty means it will outlive the payback period.
Yes. Off Grid Vault is an authorized dealer, which means your 10-year limited warranty is fully honored through us — not through a third-party ticket queue. If something fails, you deal with our team directly. We also provide free system design consultation, so if you are unsure how this inverter pairs with your battery bank or panel array, our engineers will spec the exact configuration for your setup.
With 11.4kW of continuous output across 240V split-phase, this inverter is designed to handle simultaneous heavy loads. A typical well pump draws 1,500-3,000W surge, and a refrigerator cycles at 400-800W. Combined with lighting and other baseline loads, you remain well within the rated 47.5A output current. For a free system design consultation, share your specific load list and our engineers will confirm the fit.
This inverter supports lithium-ion batteries within a 120-500V voltage range with a maximum charge and discharge current of 50A. When designing your system, our engineers will match a LiFePO4 battery bank to this inverter based on your desired days of autonomy and daily kWh consumption. LiFePO4 delivers 10-plus years of cycle life at 80% depth of discharge — the chemistry most off-grid builders insist on for long-term reliability.
Yes. This inverter supports generator input, allowing a generator to act as a grid source during extended cloudy periods or when battery reserves run low. The inverter manages the transition between solar, battery, and generator power automatically. For homesteads in regions with limited winter sun, this hybrid capability means you are never forced to choose between going dark or running a generator full-time.
This inverter carries a limited 10-year warranty from SunGoldPower, honored through Off Grid Vault as an authorized dealer. The warranty covers manufacturing defects and failures under normal operating conditions. Because we stand behind every product we sell, warranty claims go through our team — not a faceless support portal. For installed systems, our team assists directly with the manufacturer to resolve issues. Full warranty terms are available on request.
