If your load is resistive loads, such as: bulbs, you can choose a modified wave inverter. But if it is inductive loads and capacitive loads, we recommend using pure sine wave power inverter. For example: fans, precision instruments, air conditioner, fridge, coffee machine, computer, and so on. Modified wave can be started with some inductive loads, but effect for load using life, because capacitive loads and inductive loads need high quality power.
Different types of load demand for power are different. You can view the load power values to determine the size of the power inverter.
Notice: resistive load: you can choose the same power as the load.
Capacitive loads: according to the load, you can choose 2-5 times power.
Inductive loads: according to the load, you can choose 4-7 times power.
We usually believe that cables connecting battery terminal to inverter shorter is better. If you are just standard cable should be less than 0.5M, but should correspond to the polarity of the batteries and inverter-side outside. If you want to lengthen the distance between battery and inverter, please contact us and we will calculate the recommended cable size and length. Due to long distances using a cable connection, there will be a reduced voltage, which means that the inverter voltage would be far below the battery terminal voltage, this inverter will appear under voltage alarm conditions.
We will usually have a formula to calculate, but it is not hundred percent accurate, because there is also the battery's condition, the old batteries have some loss, so this is only a reference value:
Work hours = battery capacity * battery voltage *0.8/load power (H= AH*V*0.8/W)
All the exported products meets CE, RoHS, IP30,SGS,CCC certification, hot selling to North America, South America, Europe, Australia, Middle east, Africa, Russia,Japan and other Asian countries.We pay important attention to research and development. Many OEM and ODM projects for customers was very successful.
