with charge is a combination of an inverter, battery charger and transfer switch into one complete system. When AC power is available, the inverter recharges the batteries. It also allows any surplus AC power to pass through and power downstream AC loads, such as a television set or microwave oven. When AC power is disconnected, the unit inverts DC battery power into AC electricity.
They have the following characteristics:
●Have charger can charge for battery, constant voltage and stable output, strong impact resistance, under 50℃ at full load;
●Protections: low-voltage, over voltage, over load, high temperature, earth leakage;
●Isolated circuit, strong impact resistance, constant voltage and stable output, low-interference;
●Advanced automatic constant circuit, prolong battery life;
●Perfect protection against battery under voltage, overload, short-circuit;
●Microprocessor control guarantees high reliability;
●Can work with inductive load such as air conditioner, motor door and so on;
●Having grounding devices to improve safety and excellent component to lower interference; inner fan is intelligent and will not work until the wattage reaches 1/3 of inverter;
●With 100% full power, efficiency reaching up to 90%;
●USB charging port +5VDC, 500mA;
●Isolated output, soft start;
●Battery low voltage alarm;
●Cooling fins and load controlled fan.
