Common Questions

Can I connect more inverters together?

Yes — beyond the 2 inverters included, up to 6 identical inverters can run in parallel in single-phase (120VAC), split-phase (240VAC), or three-phase (208V) configurations.

What's the actual usable battery capacity?

30.72kWh combined from six 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 a server rack cabinet for the batteries, rather than mounting them individually.

Can I add more solar panels later?

Yes — this system is easily expandable, letting you add more batteries and solar panels as your energy needs grow, per the manufacturer's own product description.

Do I need a licensed electrician to install this?

Given the scale of this system — dual 10,000W inverters, a 30.72kWh battery bank, and 32 panels — installation should be handled by a qualified, licensed electrician familiar with your local code.
