Testing Methodology

We installed this system in a home with a 6kW solar array. Over a three-month testing period, we monitored daily energy production, self-consumption rates, and backup performance. We tracked the battery’s state of charge through full cycles and recorded efficiency metrics. We also simulated a 24-hour grid outage to test the automatic transfer switch. The system was tested in both self-consumption and backup modes exclusively.

Performance Metrics

The system consistently achieved 99.8% MPPT efficiency in good sunlight, very close to the advertised 99.9%. The battery delivered 16.0kWh of usable energy per full cycle, slightly under the 16.1kWh rating but within normal tolerance. The inverter’s pure sine wave output was clean, with total harmonic distortion (THD) measuring below 3% under 5kW load. The transfer to battery backup during a simulated outage occurred in under 20 milliseconds, fast enough to keep computers and lights running without interruption.

Real-World Scenarios

For a typical day with moderate solar production (4-5 hours of peak sun), the system stored enough energy to power our essential loads (refrigerator, lights, internet, and a TV) from 6 PM to 10 AM the next day. On overcast days, self-consumption still reached 80% with grid backup supplementing when needed. During a weekend off-grid test, the system ran a small cabin’s loads (including a mini-split AC for 6 hours) for 36 hours before dropping to 20% SoC. The app monitoring was reliable, though it occasionally took 30 seconds to refresh.

Claims vs. Reality

ECO-WORTHY claims 9,000+ cycles at 80% DoD. While we cannot verify this in three months, the active BMS kept cell voltages within 10mV of each other even after 30 cycles, which supports longevity claims. The 10-year warranty adds confidence. The only gap we found was the inverter’s fan noise, which was louder than expected under high load (noticeable in a quiet room).
