The hybrid inverter combines two units: 3000W 24V DC to 230V AC Pure Sine Wave Inverter, much better than Modified Sine Wave Inverter, protect appliance life with no electromagnetic pollution. 60A MPPT Charge Controller with 99.9% high efficiency, 30% higher than the PWM charge controller. Smart cooling fans inside prevent overheating condition, hybrid inverter overcharge and over-discharge protections protect the battery's capacity, built-in connection ports protect the unit from effect of environmental factors. It's able to charge and discharge different kinds of 24V battery banks, including Gel, AGM, Lithium,
