Overview

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!

Common Questions

Can I add more solar panels later?

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.

Can I connect multiple inverters together?

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.

What's the actual usable battery capacity?

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.

Do I need a licensed electrician to install this?

Given the voltages, currents, and battery wiring involved, installation should be handled by a qualified, licensed electrician familiar with your local code.
