A complete off-grid solar system — 6,500W split-phase inverter, 10.24kWh of LiFePO₄ battery storage, and eight 415W monocrystalline panels — sized for a cabin, shop, or RV.
Introducing our Solar Panel Kit – the perfect starting point for powering your off-grid cabin, shop, RV, or other small to medium-sized setups. This comprehensive package includes 8 x 415W solar panels, a 10.24 kWh battery, a 6500W solar inverter, and all necessary solar cables. Designed to deliver approximately 13 kWh of energy per day with about 4 hours of sunlight, this system can comfortably support properties using around 390 kWh per month.
Built with flexibility in mind, the kit allows for easy expansion, accommodating up to 6 identical inverters in parallel configurations for single-phase (120VAC), split-phase (240VAC), or three-phase (208V) systems. Plus, you can add additional batteries and solar panels as your energy needs grow. Embrace off-grid living and adventure with the freedom and reliability of solar energy!
Rated output with double the power available briefly for motor starts and other high-draw moments.
Runs standard household circuits and larger 240V appliances from the same system.
Two MPPT trackers support room to add panels beyond the 8 included, up to the system's rated ceiling.
Check system status and performance remotely via the WatchPower app, without needing to be on-site.
Parallel up to 6 identical inverters for single-phase, split-phase, or three-phase configurations.
Meets the standard utilities and inspectors look for on grid-interactive and off-grid inverter equipment.
Each LiFePO₄ battery is rated for at least 7,000 cycles to 80% depth of discharge — a 15-year design life.
Grade-A monocrystalline cells backed by a 25-year linear product warranty on the panels.

Yes — the inverter's two MPPT trackers support up to 8,000W of solar input in total, well above the 3,320W (8×415W) included in this kit, leaving room to expand.
Yes — up to 6 identical SP6548 inverters can run in parallel, supporting single-phase (120VAC), split-phase (240VAC), or three-phase (208V) configurations as a system grows.
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.
Given the voltages, currents, and battery wiring involved, installation should be handled by a qualified, licensed electrician familiar with your local code.
Great system with a very responsive customer service. You will need the battery bus bars, the battery cables from the 200A breaker to the bus bars/inverter, and something to mount the breaker that comes with the kit; the din rail is not included. You will not be able to use the inverter lugs that come with the equipment and the #2/0 cable as indicated in the wiring diagram; the #2/0 cable will not fit on the lugs. You will have to order the battery cable with lugs; make sure you nail down the exact size prior to ordering. We have this system connected to our house using a interlock kit at our main panel, with no grid connection, currently on a 30A, 2-Pole breaker. It's saving us about $100 a month on utility bills; we are using the utility power as a emergency source, only when there's no sun. There's no input breaker on the inverter, so you will have to add that. The Inverter programming and interface is user friendly. Overall, I would definitely recommend a system like this, and we would like to purchase another (8) panels at some point. Good luck.

Recently set up my off Sun Gold off grid system in Big Bend region in TX. Super easy set up and works like a charm. Had a few question during and after installation and tech support always provided excellent support. A happy customer.

I recently installed the SGR-6510E off-grid solar kit, and I''m very impressed with the performance. The 6500W inverter handles both 120V and 240V loads smoothly, and the 10.24kWh LiFePO4 battery provides plenty of storage for overnight use.

I was able to install the system myself and get up and running with just a few questions which were answered within 12 hours or less.
I have bought more panels to increase my light gathering power.
This is for an off grid shop with table and chop saws, drill press, and planer. All work with no problem.

Chose this one for my cabin. It was installed by a regular electrician. Very happy with it
