A complete off-grid solar system — 8,000W dual-MPPT split-phase inverter, 10.24kWh of Bluetooth-enabled LiFePO₄ battery storage, and twelve 450W monocrystalline panels.
Explore our full selection of Sungold Power Kits to compare different configurations and find the best fit for your energy needs.
Rated output with double the power available briefly, supporting motors up to 5HP.
Runs standard household circuits and larger 240V appliances from the same system.
Two solar charge trackers built directly into the inverter, supporting up to 11,000W of combined solar input at 99.9% tracking efficiency.
Certified by ETL to UL1741, alongside IEC62109-1/2 safety standards.
Parallel up to 6 identical inverters as a system's power needs grow.
Each 12V battery pairs with a mobile app for live voltage, SOC, and cell-level data.
Batteries self-heat below 33.8°F to protect charging performance in cold conditions.
182mm Grade-A monocrystalline cells backed by a tiered 25-year output warranty and 12-year material and workmanship coverage.

A complete, self-contained 8,000W system with split-phase output, sized for off-grid homes, cabins, and backup power applications.
Yes — two MPPT trackers are built directly into the inverter, supporting up to 11,000W of combined solar input.
10.24kWh combined from four 12V 200Ah LiFePO₄ batteries, each with its own Bluetooth app for live voltage, SOC, and cell-level monitoring.
Up to four 12V batteries can be connected in series (staying under the 58.4V maximum) to reach the system's 48V nominal input.
Yes — the inverter supports up to 11,000W of solar input in total, above the 5,400W (12×450W) included in this kit.
Given the voltages, currents, and battery wiring involved, installation should be handled by a qualified, licensed electrician familiar with your local code.
