Additional Documentation
Common Questions
Does this inverter have a built-in solar charge controller?
Yes — MPPT solar charging is built directly into the inverter, supporting up to 5,000W of solar input at up to 99.9% tracking efficiency.
What’s the actual usable battery capacity?
10.24kWh combined from two 5,120Wh LiFePO₄ server rack batteries, each rated for at least 7,000 cycles to 80% depth of discharge.
Is there a higher-capacity option available?
Yes — for significantly higher power and storage, the manufacturer also offers an 8,000W kit with the same 10.24kWh battery capacity but a larger 5,400W solar array.
Can I add more solar panels later?
Yes — the inverter supports up to 5,000W of solar charging, above the 2,490W (6×415W) included in this kit.
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.
