Performance & Real-World Testing

Testing Methodology

We tested the HumsiENK battery over a three-week period in a simulated off-grid solar system. We connected it to a 5000W hybrid inverter with solar panels and monitored its performance under various loads, including refrigerators, lights, and a well pump.

Performance Metrics

The battery consistently delivered its rated capacity. The 3A active balancing kept all cells within 5mV of each other during the entire charge and discharge cycles. The voltage remained stable under a constant 3000W load. Charge acceptance was excellent, reaching 95% of full capacity in just 1.5 hours with a 50A solar charge controller.

Real-World Scenarios

During a simulated grid outage, the battery provided seamless backup power to our test lab for over 8 hours without dropping below 20% SOC. It handled the start-up surge of a deep well pump without any voltage sag or BMS triggering. We also tested it in a steep temperature swing and the low-temperature cutoff function worked perfectly, protecting the cells.
