Many ordinary people misunderstanding about inverter, one of them is a long time endurance inverter.
The fact is that the resistance is determined by this formula
Note:Long endurance is not determined by the watt inverter, but is determined by volt battery, battery and load amperes
The formula is:
Volts x amps = watts / hour : load capacity
EXAMPLE: 12 Volt x 200 Ah= 2400 watts/hour with load capacity 200 watt= 12 hour
This formula applies only to new battery and until the new battery is discharged.If the battery is old then the amount will be reduced from the above formula
