A complete off-grid solar system — two paralleled 6,500W split-phase inverters, 20.48kWh of powerwall LiFePO₄ battery storage, and twelve 370W monocrystalline panels.
This off-grid solar power kit includes almost everything you need to bring solar power and battery storage to your remote home, cabin, or other location. It includes 12 x 370W solar panels, four 5.12kWh Powerwall batteries, two 6500W solar inverters, and two sets of solar cables and brackets. The system is capable of producing around 17.7kWh per day based on 4 hours of sun.
Additionally, it is expandable to include up to six identical inverters that can be paralleled in single-phase (120VAC), split-phase (240VAC), or three-phase (208V). You have the flexibility to add more batteries and solar panels to meet your energy requirements. Get ready to enjoy the freedom of off-grid living with our solar energy kit!
Two 6,500W inverters paralleled, with double the combined power available briefly for motor starts and other high-draw moments.
Runs standard household circuits and larger 240V appliances from the same system.
Each inverter has two MPPT trackers, supporting up to 8,000W of solar input per unit.
Parallel up to 6 identical inverters in single-phase, split-phase, or three-phase configurations.
Add more batteries and solar panels in the future as your energy needs grow.
Meets recognized North American safety standards for solar inverter equipment.
Junction box rated for full submersion protection, backed by a 25-year linear product warranty.
166mm Grade-A monocrystalline cells for a higher conversion rate per panel.

With about 4 hours of direct sunlight, this system produces roughly 17.7kWh per day — suited for remote homes, cabins, or other off-grid locations, per the manufacturer's own description.
Two 6,500W BluePower SP6548 inverters are paralleled to reach the system's combined 13,000W rating. Up to 6 identical units can be paralleled in single-phase, split-phase, or three-phase configurations.
Yes — each BluePower SP6548 has two built-in MPPT trackers, so no separate charge controllers are needed for this kit.
20.48kWh combined from four 5.12kWh powerwall batteries, each rated for at least 7,000 cycles to 80% depth of discharge.
Yes — you have the flexibility to add more batteries and solar panels to meet your energy requirements, per the manufacturer's own product description.
Given the scale of this system — two paralleled 6,500W inverters and a 20.48kWh battery bank — installation should be handled by a qualified, licensed electrician familiar with your local code.
