Additional Documentation
Common Questions
Does this inverter have a built-in solar charge controller?
Yes — two MPPT trackers are built directly into the inverter, supporting up to 11,000W of combined solar input.
What’s the actual usable battery capacity?
10.24kWh combined from four 12V 200Ah LiFePO₄ batteries, each with its own Bluetooth app for live voltage, SOC, and cell-level monitoring.
How are the batteries wired together?
Up to four 12V batteries can be connected in series (staying under the 58.4V maximum) to reach the system’s 48V nominal input.
Can I add more solar panels later?
Yes — the inverter supports up to 11,000W of solar input in total, above the 5,400W (12×450W) 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.
