1. How to select proper inverter? Before purchasing any inverter, the following questions should be made clearly: DC voltage, loading size and type .
Generally, DC voltage of the inverter has only one grade, users can choose corresponding inverter according to DC power supply.
Loading size and type are the important factors that users should consider when select any inverter. Maximum output power of inverter is fixed,
if choose loading with compressor, its starting power will exceed several times of rated power, so inverters with big output power have to be chosen as a result.
