hybrid inverter dc to ac 4000w

   When choosing an off-grid inverter, in addition to paying attention to the output waveform and isolation type of the inverter, several technical parameters are also very important, such as system voltage, output power, peak power, conversion efficiency, switching time, etc. The choice of these parameters has a great influence on the power demand of the load.

Power: 4000W

Controller: MPPT Solar charge controller  50A

Small power does not matter hf power frequency, hf cheap, expensive, but cheap hf machine is difficult to find easy to use, there are easy to use is not cheap, from the technical point of view, low power hf opportunity is a lot better, you need to carefully look for, do not single figure cheap

    Conversion efficiency: The conversion efficiency of the off-grid system includes two aspects. One is the efficiency of the machine itself. The circuit of the off-grid inverter is complex and needs to undergo multi-stage conversion, so the overall efficiency is slightly lower than that of the grid-connected inverter, generally 80-90. %, the higher the power of the inverter, the higher the efficiency, the higher the efficiency of high-frequency isolation than the power frequency isolation, and the higher the system voltage, the higher the efficiency. The second is the efficiency of battery charging and discharging, which is related to the type of battery. When photovoltaic power generation and load power consumption are synchronized, photovoltaics can be directly supplied to the load for use without battery conversion.
