300w solar inverter works efficiently light

300w solar inverter works efficiently light, high light efficiency, 300-watt high-frequency inverter board, measuring 16x9x7 cm, can be 12v to 220v inverter. Pure sine wave power inverter is widely used in automotive electronics, field of marine electronics, daily life, standby power, wind power, solar power and other conventional frequency inverter directly (50HZ) inverters, frequency transformer so huge volume, heavy weight, low inverter efficiency, generally only 65% or so.
