A complete off-grid solar system — 6,500W split-phase inverter, 5.12kWh of LiFePO₄ battery storage, and six 370W monocrystalline panels — sized for a cabin, shop, or RV.
Introducing our complete off-grid solar kit, designed as the perfect starting point to power your cabin, shop, or RV entirely off-grid. This comprehensive package includes six 370W solar panels, a 5.12kWh Powerwall battery, a 6,500W solar inverter, and a complete set of solar cables. With an approximate daily production of 5.92kW based on four hours of sunlight, this kit offers reliable energy generation.
Ideal for cabins, shops, RVs, and similar setups consuming around 177 kWh per month, this system provides the autonomy and sustainability you need. Additionally, the modular design allows for easy expansion with additional batteries and solar panels to suit your specific requirements.
If you're looking for a broader selection of solar solutions, explore our Complete Solar Panel Systems collection— featuring a variety of high-quality kits tailored to different energy needs and installation types.
Embark on the journey of off-grid living and embrace the adventure with our solar energy kit!
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 solar charge controllers built directly into the inverter, no separate hardware needed.
Included, not optional — check system status and performance remotely via the mobile app.
Parallel up to 6 identical inverters for up to 39kW combined, in single-phase, split-phase, or three-phase configurations.
Meets the standard utilities and inspectors look for on grid-interactive and off-grid inverter equipment.
Confirmed for this battery specifically — not just a general lineup-wide figure.
182mm Grade-A monocrystalline cells backed by a 25-year linear product warranty.

Yes — the SPH6548P inverter has two MPPT solar charge controllers built directly into the unit, no separate hardware needed.
Yes — up to 6 identical SPH6548P inverters can run in parallel for up to 39kW combined, in single-phase (120VAC), split-phase (240VAC), or three-phase (208V) configurations.
5.12kWh from a single LiFePO₄ battery, rated for at least 7,000 cycles to 80% depth of discharge, backed by a 10-year warranty confirmed for this product specifically.
This product's own marketing states support for up to 16 batteries in parallel. The battery's own manual documents a higher theoretical addressing capacity of 63 via its DIP-switch table — worth confirming the practical limit directly before scaling significantly.
Given the voltages, currents, and battery wiring involved, installation should be handled by a qualified, licensed electrician familiar with your local code.
