Question:our household appliances including (Air conditioning, refrigerator, washing machine)toal 4kw,use the 5 hours in everyday ,how many pcs solar panel and battery,how much watt solar inverter?



1.solar Inverter watt choose 

Air conditioning, refrigerator, washing machine all is inductive load,so need around 4kw*1.5=6kw

so inverter need at least 6kw (Rated Power)


 2.Battery choose

According the inverter is DC 48V 6KW,if use the 12v 200AH battery

so one battery 12V*200AH=2400VAH=2400*08=1920WH

The household appliances need total use the 5 hours in everyday,5 hours total


So 1920WH*x(pcs)*0.5(Depth of discharge)=20000WH   X=20pcs 



3.Solar panel pcs,firstly you must know your loacl average sunshine time

if average sunshine time is 6 hours everday,you use the 200w solar panel just

X(pcs)*200W*8*0.6(loss)=20000WH  X=20pcs


Finally:inverter if 6kw 48V DC so battery and solar panel need 4 pcs in serise to a group

and  5 groups to in parallelfinally

Our Strength






There are several factors that should be taken into account when determining

the total cost of ownership over the life of the battery.
1.Price: A battery with a low price is always attractive, but if low price comes

at the expense of quality and battery life, the need for frequent battery replacements

could boost the cost over time. That’s why it’s important to consider issues other than

price when making the decision.

2.Capacity: Battery capacity is important because it’s a measure of the amount of energy

stored in the battery.

3.Voltage: The battery bank voltage must be considered to ensure it matches the system requirements. The battery bank voltage is often determined by the inverter specifications

if installing a DC-to-AC system or by the voltage of the loads in a DC system.
4.Cycle Life: The most critical consideration is cycle life, which provides the number of discharge/charge cycles the battery can provide before capacity drops to a specified

percentage of rated capacity. Batteries from different manufacturers may have the same

capacity and energy content and be similar in weight. But design, materials, process and

quality influence how long the battery will cycle.




Q: Can you print my logo on the battery cover?

A: Yes, OEM is available,we can print your logo on the battery case, and you can offer your



Q: What's the payment term?

A: We accept T/T, 30% deposit & 70% balance payment before shipping, and Western Union. 


Q: How's the delivery time?

A: Usually it takes about 10-15days for production varies with products.
