1. Choose a metal shell inverter: On the one hand, the Buy 48V low frequency inverter with metal shell has good heat dissipation characteristics and long service life, and on the other hand, it also avoids the danger of fire caused by the internal overheating.

2. For the same power the 48V low frequency inverter, if the volume is similar, the heavier one is preferred. The weight of the product is heavier, which means that the outer casing is thicker, which is conducive to heat dissipation. It also means that the internal transformer has a large power and can drive a high-power load for a long time.
3. Perfect protection function: A good Buy 48V low frequency inverter should have perfect protection function, which can protect the power supply under various conditions, and should also have sound and light alarm function, which is convenient for people to deal with in time. Generally, the protection functions that 48V low frequency inverter should have are overvoltage protection, overtemperature protection, output overload protection and short circuit protection.
4. Conversion efficiency: This is a very important indicator of the inverter, which should generally reach more than 90%. The higher efficiency of the Buy 48V low frequency inverter, the lower the heat generation and the longer the use time.
5. Pay attention to the output socket form of the Buy 48V low frequency inverter, if it can use the two-phase and three-phase plugs of the national standard
