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.
