Sungold Power · SGM-5K10M
A complete off-grid solar system — 5,000W inverter, 10.24kWh of LiFePO₄ battery storage, and six 370W monocrystalline panels — customizable with extra batteries and panels as needs grow.
Introducing our comprehensive off-grid solar system kit, designed to effortlessly bring 2.22kW of solar power and storage to mid-sized off-grid homes or remote cabins. Complete with 2PCS 51.2V 100AH PowerWall Lithium batteries and solar panel mounting hardware, this kit sets you on the path to energy independence. For a larger capacity option, check out the Sungold Power Off-Grid 5000W Solar Kit with 48VDC 120V Inverter and LiFePO4 Batteries, offering 10–24kWh of storage and 6×415W solar panels for expanded energy needs.
Equipped with a 5000W 48V 120V pure sine wave inverter, capable of powering most household appliances, our system is primed for expansion. You can seamlessly integrate up to 6 identical inverters, allowing for parallel operation in single-phase (120VAC), split-phase (240VAC), or three-phase (208V) configurations. Tailor your system to your needs by adding more batteries and solar panels as required.
Monitor your system's performance and energy data with ease through the Wi-Fi monitor, accessible via a convenient app. Embrace off-grid living and embark on the adventure of sustainable energy with our solar energy kit!
Rated output with double the power available briefly for motor starts and other high-draw moments.
Minimal energy loss whether running on battery, solar, or passthrough grid power.
Room to add panels beyond the 2,220W (6×370W) included, up to the system's rated ceiling.
Add remote monitoring hardware for system status and performance without needing to be on-site.
Parallel up to 6 identical inverters as a system's power needs grow.
Meets recognized international safety standards for solar charge controller equipment.
The LiFePO₄ battery is rated for at least 7,000 cycles to 80% depth of discharge — a 15-year design life.
Grade-A monocrystalline cells with IP67-rated connectors for weather resistance.

Yes — the inverter supports up to 5,500W of solar input in total, well above the 2,220W (6×370W) included in this kit, leaving significant room to expand.
Yes — up to 6 identical SPH5048P inverters can run in parallel in single-phase (120VAC), split-phase (240VAC), or three-phase (208V) configurations.
10.24kWh combined from two 5,120Wh LiFePO₄ batteries, each rated for at least 7,000 cycles to 80% depth of discharge — a 15-year design life per the manufacturer.
Per the manufacturer's own product description, the SGR-5KE offers a larger-capacity option with 415W panels for expanded energy needs — this kit uses 370W panels and is positioned as the smaller of the two.
Given the voltages, currents, and battery wiring involved, installation should be handled by a qualified, licensed electrician familiar with your local code.
