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.
