Power That Stays On When the Grid Goes Dark

Power That Stays On When the Grid Goes Dark

Most grid-tied systems marketed as energy independence go completely dark the moment the utility fails. That defeats the purpose. This SunGoldPower 11.4KW hybrid inverter operates independently — 200A whole-home backup means your fridge, well pump, and lights keep running through multi-day outages. At Off Grid Vault, every component we carry is pre-vetted to work together, so your inverter communicates properly with your battery BMS and charge controller. No mix-and-match guesswork, no incompatible voltage protocols. This is the unit we would install on our own cabin — because when the grid drops, there is no room for surprises.

15kW Solar Across Three Independent MPPTs

15kW Solar Across Three Independent MPPTs

Three separate MPPT controllers let you harvest up to 15,000W from your solar array at 600V max input voltage. That means fewer strings, longer runs, and less voltage drop between your panels and your power center. The 90V start-up voltage ensures early-morning production even in low-light conditions. Whether you are wiring south-facing roof arrays or ground-mount strings across a clearing, this inverter handles the architecture without clipping. At 11,400W continuous output, you have headroom to run a refrigerator, well pump, microwave, and shop tools simultaneously — not just one at a time.

IP65-Rated for Real-World Conditions

IP65-Rated for Real-World Conditions

An IP65 enclosure means this inverter handles dust, rain, and humidity without a secondary shelter. At 103.6 lb and 17.6 x 35.5 x 10.6 in, it wall-mounts securely in a garage, utility room, or covered exterior wall. Built-in rapid shutdown cuts DC power instantly during emergencies — a critical safety feature for any grid-independent installation. The 10-year warranty reflects the build quality, and lithium-ion or lead-acid battery compatibility means you are not locked into one chemistry. Monitor and adjust settings through the LCD display or mobile app, keeping full control of your system without climbing to the mount point.

“Mounted this in my shop last fall — 11.4kW continuous output runs my welder, air compressor, and shop lights all at once without a hiccup. The 200A passthrough means I did not have to rewire my sub-panel. App monitoring is straightforward and the IP65 rating gives me peace of mind since it is on an exterior wall. Off Grid Vault answered my battery compatibility questions before I ordered. Finally done with the power company for my workshop.”

Frequently Asked Questions

At $2,461, this inverter is the core of a system that can eliminate a $250–$400 monthly utility bill. Pair it with panels and a battery bank, and your payback window shrinks to 3–4 years depending on your kWh consumption. After that, every dollar previously sent to the utility stays in your pocket. Finance with Affirm starting at $205/month — less than most electric bills — and the system effectively pays its own payment from day one.
Off Grid Vault stands behind every product we carry with a 30-day performance guarantee and direct after-offer support from people who understand off-grid systems — not a generic marketplace help desk. This SunGoldPower inverter carries a 10-year limited manufacturer warranty, and we assist with warranty claims on your behalf. When you call us, you talk to someone who knows the difference between split-phase and three-phase, LiFePO4 and lead-acid. That expertise does not ship with a box from a big retailer.
This inverter supports lithium-ion and lead-acid batteries within a 40V to 64V range at 51.2V nominal — covering most 48V LiFePO4 banks on the market. On the solar side, three MPPTs accept up to 600V input, giving you flexibility with panel configurations. Not sure if your existing components match? That is exactly what our free system design consultation is for. Tell us your battery specs and panel layout, and we will confirm compatibility before you buy. No guesswork.
This inverter ships free via LTL freight. Wall-mounted installation at 103.6 lb requires two people and standard electrical tools. For experienced installers, the physical mount and wiring can be completed in a few hours. Configuration — setting battery parameters, MPPT limits, and grid-tie or off-grid mode — is done through the LCD display or mobile app. If you need guidance on sizing the rest of your system around this inverter, request a free system design consultation and we will map out the full build before your unit arrives.
This unit is covered by a 10-year limited manufacturer warranty. As your point of purchase, Off Grid Vault assists with warranty claims — you deal with us, not a faceless support queue. The IP65 enclosure and built-in rapid shutdown are designed to prevent the most common failure modes: moisture ingress and electrical surges. For the first 30 days, our performance guarantee applies to uninstalled units in original packaging. For post-installation issues, the 10-year warranty handles defects in materials and workmanship. We recommend pairing this inverter with a compatible LiFePO4 bank for the longest system lifespan.
Yes. This inverter supports parallel connections of up to 9 units, scaling to a 102.6kW system. That means you can start with a single unit powering a cabin or backup load, then add inverters as you build out. The three MPPTs also give you room to add solar panels without swapping hardware. Start with what you need today — the architecture grows with you. If you want help planning a phased build, our free system design consultation maps the expansion path upfront.
