Sdp-40kw Sandi pure sine wave series inverter is one of the most advanced dc to ac conversion products in the world, it has the main advantages of high quality sine wave ac output, microcomputer control, humanness design, and it is simple, stable, no noise and no pollution. It is suitable use for areas without electricity, vehicles, ships, solar energy, wind turbine etc. The inverter can also supply ac voltage to all kinds of power tools, air conditioners, electric motors, refrigerators, fluorescent lights, televisions, electric fans and other power supply. The inverter output waveform is pure sine wave; this kind of ac power is suitable for most industrial electronics and home appliances, the power supply features much better than other modified sine wave and square wave. Technical features: 1, two kinds of start mode: reduction voltage start and variable frequency start. Customers can set start mode according to the nature of their load. 2, the output frequency can be set, this function is very convenient for customer. 3, the output voltage can be set between +20 % to -40 % of rated voltage. It¡¯s a great convenience to users. 4, the dc input voltage range can also be set. Over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point all can be set via the lcd panel. Convenient for increasing or reducing the quantity of batteries, photovoltaic modules also can be used flexibly. Standard export honeycomb carton packing with pallet
