1.How to choose suitable inverter?
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.

2.How do I choose the size of the inverter?
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.

3.How connection between batteries and an power inverter?
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.

4.How to calculate the load of working hours requires configuration
of the battery size?
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)
