How to choose an inverter?
1. Determine what the battery voltage and capacity are?
If your battery output voltage is 12V, you need to choose a 12V inverter. The battery capacity directly affects the capacity of the charger. The larger the battery capacity, the more electrical appliances can be charged.
For example, 12V battery * 60AH capacity * 0.8 conversion rate + 576W and below can be charged.
2. What electrical appliances can be charged?
Electrical appliances are divided into resistive loads and inductive loads.
Resistive appliances:
Household appliances such as computers, TVs, fans, and electric lights.
Inductive appliances:
Refrigerators, washing machines, juicers, hand drills, water pumps, sanders, etc.
Resistive appliances have no starting power, while inductive appliances have starting power, which is generally 3 to 7 times the starting power.
Therefore, it is necessary to determine whether the appliance is a resistive appliance or an inductive appliance.
However, the starting power of an inductive load appliance is 3-7 times that of an inductive load appliance. If the continuous power meets the conditions, the starting power must also meet the conditions to drive.
For example:
If the battery is 12V/60AH, can a 2000W inverter drive a 500W hard drill?
1. First look at the maximum power of the battery charger: 12*60*0.8=576W, >500W.
2. Determine whether the appliance is a resistive appliance or an inductive appliance: a hand drill is an inductive electric drill.
3. The continuous power of a hand drill is 500W, and the continuous power of a 2000W is 1000W, >500W.
The starting power is generally about 3 times (the starting power of different appliances is different), so 500W X 3 = 1500W, and the starting power of a 2000W inverter is 2000W, >1500W. So a 500W hand drill can be used with a 12V/60AH battery and a 2000W inverter.
Other appliances can also be judged in this way.
If you encounter any problems or don't understand the operation, you can also consult customer service, thank you!
