Additional Documentation
Common Questions
Can I add more solar panels later?
Yes — the two inverters combined support up to 22,000W of solar input, well above the 13,280W (32×415W) included in this kit, leaving room to expand.
Can I connect more inverters together?
Yes — up to 6 identical SPH8048P inverters can run in parallel in single-phase (120VAC), split-phase (240VAC), or three-phase (208V) configurations.
What’s the actual usable battery capacity?
25.6kWh combined from five 5,120Wh LiFePO₄ batteries in the included server rack cabinet, each rated for at least 7,000 cycles to 80% depth of discharge.
Are the batteries stored in a rack or individually?
This kit includes an enclosed server rack cabinet sized for all five 100AH batteries, rather than mounting them individually.
Do I need a licensed electrician to install this?
Given the scale of this system — dual inverters, a 25.6kWh battery bank, and 32 panels — installation should be handled by a qualified, licensed electrician familiar with your local code.
