1000w Pure Sine Wave Low Frequency Inverter

FTS series 12v 24v 48v pure sine wave hybrid solar power inverter 

How the inverter works:

1. Direct current can be converted into alternating current through an oscillating circuit

2. The obtained alternating current is then boosted by the coil (at this time, the alternating current of square wave is obtained)

3. Rectify the obtained alternating current to obtain a sine wave

      Inverter is a DC to AC transformer, which is actually a voltage inversion process with Adapter. The Adapter converts the AC voltage of the mains grid into a stable 12V DC output, and the Inverter converts the 12V DC voltage output by the Adapter into high-frequency high-voltage AC; both parts also use the pulse width that is currently used more frequently. Modulation (PWM) technology. Its core part is a PWM integrated controller.

    The input part has 3 signals, 12V DC input VIN, work enable voltage ENB and Panel current control signal DIM. VIN is provided by Adapter, ENB voltage is provided by MCU on the main board, its value is 0 or 3V, when ENB=O, the Inverter does not work, and when ENB=3V, the Inverter is in normal working state; while the DIM voltage is provided by the mainboard, The variation range is between 0 and 5V. When different DIM values are fed back to the feedback terminal of the PWM controller, the current provided by the Inverter to the load will also be different. The smaller the DIM value, the greater the current output by the Inverter.
