Power Inverter Pure Sine Wave 3000W 3 Phase UPS + Charger 48V to 380V

3Phase Inverter 3KW Low Frequency Inverter with AC Charger 3000W UPS Pure SineWave Inverter DC 48V to AC 380V Grid off Inverter  ​There are 2 kinds of working mode： 1,City power priority, when it has no city power, inverter will automatically switch to battery power to supply the load (UPS function); 2,Battery power priority: When battery power is lower, inverter will automatically use bypass function to take the load, NO NEED charge to battery. You can only choose one of the working modes.Please leave a message for your order.   Performance Specification of Intelligent inverter： (1) The inverter is designed by our company independently; it’s controlled by CPU, high quality and modify sine wave intelligent inverter (2) Our product is used for the many kinds of the single-phase equipments, example: motor, screw tools, tube light etc. Family equipments, and also it can be used for the industry and communication equipments. (3) Single key intelligent switching, easy to operated (4) Output short circuit protection (when the inverter is working on battery mode): when there is short circuit, the inverter will indicate it and the machine will shut down automatically. (5) Overload protection: when there is overload, the machine will prompt you and protect the inverter from being damaged automatically. Over 100%-120%, inverter shuts down 30s later, over 150%, inverter shuts down at once. (6) Internal circuit can protect the battery .when the battery voltage is under the 15% level, the inverter will be shut down at once.
