THA500 is modified sine wave inverter which converts DC power to AC power. The power is used for household appliances, solar devices and telecommunication equipments when no grid power is available. Its output voltage is always within 10% of rated voltage until it shutdown for overload or other reasons. The special design of circuit and tough components protect the inverter from being easily damaged, even when the starting power of those equipments is more than 3 times of that of the inverter. Besides those advantages, THA inverter also has 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. All these designs are made to prolong its span.
