User Manual

It depends on the power of the appliances. Choose the power inverter based
on the maximum power of the AC load. For resistive load such as cooker for
800w, choose1000W inverter. For inductive load such as refrigerator,
A/C,pump,motor, compressor ect, the surge power can be 5-10 times higher.
Please choose the power inverter with the power of 5-10 times or higher.
6.3. How long can the power inverter last to power up my appliances?
It depends the power of the AC appliances and the capacity of the batteries.
For example, for a 12V,100Ah battery to power up an appliance of 300W.
Theoretically, the working time=12V*100AH*0.8*0.9/300w=2.88hours. Note:
0.8 is the battery discharge coefficient,0.9 is the inverter’s conversion
efficiency)
6.4 How to connect the batteries?
6.4.1Series Connection
When two or more batteries are connected in series, the voltages will add up
but their Ah capacity remains the same. Please see the chart. When the 4 pcs
of 6V, 200Ah batteries connected in series, a battery bank of 24v with a
capacity of 200Ah will be made.
6.4.2 Parallel Connection
When two or more batteries are connected in parallel, the voltage will remain
the same but their Ah capacity will add up. Please see the chart. When the 4
pcs of 12V, 100Ah batteries connected in parallel, a battery bank of 12v with a
capacity of 400Ah will be made.
