Note:
1. The inverter cannot be connected to the public mains and the AC output line cannot be touched by hand. If the battery cable is extended, the corresponding wire diameter must be double grease. (For example, the 12 V 2000 W inverter is equipped with a 10 square 50 cm battery cable. In actual use, the cable can be 100 cm long and the wire diameter should be thickened to 20 squares, i.e. 20 square 100 cm)
2. The two output wires of the inverter are live wires, so there is no problem with the grounding. Do not use one as an earth cable. It is not designed for grounding.
3. Connect the inverter to the load. Do not connect air switch or residual current circuit breaker in the middle. Hard operation does not protect the inverter, it will damage the inverter.
This inverter can transport electrical appliances with a power of no more than 1000W, and the battery you use must meet the requirements.
The formula for calculating the electrical power that the battery can transport is:
Load capacity electrical power = battery voltage * battery capacity (Ah) * 0.9
(If you use multiple batteries in row, you only need to calculate the voltage of a battery, but you need to calculate the sum of all battery capacities.)
For example, the load capacity of a 12 V 80 Ah battery is 12 x 80 x 0.9 = 864 W.
The formula for calculating battery life is:
Battery life = battery volt, battery capacity (Ah) x 0.9 x 0.8 / electrical power
For example, if you use a 12V 80Ah battery with a 750W laser printer, the battery can deliver 12 x 80 x 0.9 x 0.8 / 750 = 0.92 hours. So if you need to work longer, you need a large capacity of batteries, the larger the battery capacity, the longer the working time.
