Inverter for Solar Panel System

700 watt to 6000 watt off grid inverter system


The waveforms of the power inverter are mainly divided into two categories, one is the sine wave inverter and the other is the modified wave inverter. As to the modified wave inverter, it adopts the PWM pulse width modulation means to generate the modified wave output. Since there is a harmonic distortion of around 20%, it can’t carry an inductive load such as an air conditioner, but it can carry a resistive load such as a lamp. The modified sine wave inverter adopts a non-isolated coupling circuit. The equipment has a simple structure and high efficiency. The pure sine wave inverter adopts the isolated coupling circuit design, which has a rather complicated circuit and a rather high cost. Therefore, it can be connected to any common electrical equipment (including TV set, liquid crystal display and so on, especially the inductive load such as the refrigerator) without any interference.

I love this off grid inverter
The LCD display of the off-grid inverter is easy to read and understand. The LEDs are easy to see and the accompanying book includes all register values and defaults. You may only need to change two to four of these values, such as battery type and charging behavior.

Very good inverter so far
Been using this 1000 watt off grid inverter for almost a month now and it works great so far. Will keep you posted. The price was reasonable also.
