How to choose an inverter?
1.Determine what the battery voltage is, and what is the capacity of the battery? If your battery output voltage is 12V.you have to choose a 12V inverter. The size of the battery will directly affect the size of the charger. The laeger the battery,the more electrical appliances it can carry. Such as 12Vbattery *60AH capacity *0.8 conversion rate + 576W or less can be brought.
2.What kind of electrical appliances can I bring? Electrical appliances are divided into resistive loads and inductive load appliances. Resisstive appliances: computers,televisions,fans,electric lights and other household appliances. Inductive appliances: refrigerators,washing machines,jce machines,hand drills,pumps,sanders,etc. Resistive appliances do not have starting power,and inductive appliances have starting power,which is generally between 3 and 7 times. Therefore, it is necessary to detemine whether the appliances is a resistive appliances or an inductive appliance.
However, the inductive load appliance has a starting power of 3-7 times, the continuous power meets the condition, and the starting power must also meet the conditions before it can be driven.
FOR EXAMPLE
If the battery is 12V/60AH,can you use a 2000W inverter with a 500W hard drill ?
1.First look at the maximum battery charger is :12*60*0.8 = 576W,>500W.
2.Determine whether the electrical appliance is a resistive electrical appliance or an inductive electrical appliance: the hand drill is an inductive electric drill.
3.The continuous power of the hand drill is 500W,and the duration of 2000W is 1000W,>500W.
The starting power is generally about 3 times (the starting power of dofferent electrical appliances is different) so 500W X 3 = 1500W, the starting power of the 2000W inverter is 2000W,>1500W Therefore,the 500W hand drill can be used with a 12V/60AH battery and a 2000W inverter.
Other appliances can also be judged by this method.
If you have problems, do not understand the operation, you can also consult customer service, thank you!
