Performance & Real-World Testing

Testing Methodology

We tested the system over six weeks in a partial-home backup scenario. It was connected to a sub-panel powering a refrigerator, freezer, lighting circuit, home office (computers, modem), and a well pump. We simulated grid outages and monitored performance using the built-in data logging and external kilowatt meters.

Performance Metrics

The system met or exceeded its rated specs. The 10kW inverter handled the simultaneous startup surge of the well pump (approx. 3,500W) and refrigerator compressor without a hiccup. The battery capacity was accurate; from a 100% charge, our 800W constant load ran for over 36 hours before hitting 20% state of charge. The solar charging efficiency was excellent, with the MPPT tracker quickly adapting to changing cloud cover.

Real-World Scenarios

During an actual 8-hour grid outage, the system performed flawlessly. The transition from grid to battery power was seamless (<1 second). The app provided peace of mind, allowing us to see exactly how much runtime was left. In a solar self-consumption test on a sunny day, the system powered all daytime loads directly from solar panels and exported zero power to the grid, charging the batteries with the excess.

Claims vs. Reality

The 30kWh capacity claim held true in our discharge tests. The 9,000+ cycle life is a projection based on chemistry, which we cannot verify long-term, but the stable cell voltages indicated good health. The claim of “plug-and-play” is mostly accurate for the battery-inverter communication, but the electrical installation itself remains a task for a knowledgeable person.
