1. Our inverter products must be configured with battery power supply to turn into 220 AC output. There is no way to use the inverter without the battery. Please consumers understand this truth and then buy.
2, before buying, consumers must confirm how much v(voltage) how much AH(capacity) your existing battery is and how much power you want the inverter to bring. Then to determine the purchase of the appropriate inverter.
3. Battery input power: v(voltage)x current (A)-w power (W). for example, if you want to bring a rice cooker is 650w, then your battery should choose: 12V80AH or 24V40A 48V20A 60V15AH. The battery utilization rate is about 70%. Such as 12*80-960 960*70-672w this just can afford 650w rice cooker. It only takes about 20 minutes. When the battery voltage is lower than 650w, there is no way to carry it. Therefore, in order to last longer, the battery capacity must be larger than the electrical equipment to be carried. The capacity of the battery is equal to the household water tank, the larger the water tank, the longer the time. this is how the battery works.
4, the power of the inverter is the ability to carry and drive the inverter carrier, the inverter has peak power and rated power. Peak power is instantaneous power, is to drive the motor. Compressors, and other electrical appliances that need to start a lot of power instantaneously. It is equal to the power of people to pick up the burden in an instant. If the momentary force is not enough, it cannot drive these capacitive loads. Rated power is the power of the normal operation of the inverter, generally normal use can not be used with full load, to leave the rest, otherwise the machine is not durable, the utilization rate is generally 80-90%. For example, the rated power is 1000w, the normal maximum is best with 900w. this will give the machine more room and make it last longer.
5. Battery specifications: 12v(1 block) 24V(2 blocks in series)48V (4 blocks in series) 60v(5 blocks in series) 72V(6 blocks in series)
Inverter specifications: Input: 12V24V 48V 60V 72V output; 220VAC/50HZ
Therefore, what voltage of the battery must be stacked corresponding to the input voltage of the inverter. You can't pick the wrong one. You can't burn the wrong one.
6. Special reminder: the starting power of the refrigerator is 7-10 times the rated power. Generally, it is necessary to choose the rated power above 1200w and the peak power above 2600w to bring the movement.
Select enough process: First determine the battery voltage how much v how much AH-- determine what electrical appliances and how much w power to bring -- and then select the appropriate inverter input voltage and rated power.
