With about 4 hours of direct sunlight, the 32-panel array produces roughly 40.6kWh per day — enough for air conditioners, well pumps, refrigerators, televisions, workshops, and offices, per the manufacturer's own description.
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.
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.
This kit includes a server rack cabinet for the batteries, rather than mounting them individually.
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.
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.
