In this review, I will show the 2000 Watt FCHAO inverter—from the package contents, appearance, and teardown to testing the output voltage sine wave and its actual maximum power. In addition, as a continuation of the review of the Humsienk LifePO4 battery—12 Volts, 320 Amp-hours—we will perform a full discharge test to verify its actual capacity and also look at the long-term operation of the inverter and this battery under a heavy load.
We will assemble a backup power system consisting of an inverter, battery, and charger, resulting in a powerful 2 kW UPS with a capacity of 4 kWh of energy.
