PST0.3K 12v PWM pure sine wave off grid solar power inverter 300w is perfect for off-grid living, backup power and self-consumption applications, it is a pure sine wave, off grid solar inverter system with switchable 50/60 Hz frequencies.
The inverter is combining functions of inverter, pwm solar charger and battery charger to offer uninterruptible power supply. This inverter can power all kind of appliances in home or office environment, including motor-type appliances such as tube light, fan, refrigerator or air conditioner.
Off grid solar power inverter 300w with pwm solar charge controller is using a switch between the PV array and the battery. The switch is able to open and close rapidly, thus being able to pulse or “throttle back” the electricity coming from a solar panel in order to taper off the charge current as the batteries become full. Since PWM solar charge controller can operate with a switch only, the array voltage during operation is equal to the battery voltage. This means that you need to use nominal voltage solar panels with a PWM controller (36-cell panels for 12 V nominal and 72-cell panels for 24 V nominal).
