Inverter, determine the demand for electricity
Each inverter has efficiency, there are 40% and there is a high efficiency inverter 85% but usually average a 85% efficiency

Example:
1000 watt inverter which has a 85% efficiency can only be used for 850 watts

In determining the inverter needs to be considered are:
1. The number of watts you want in a back-up
2. Length of the desired resistance

1. The number of watts you want in a back-up function to choose an inverter that suits your needs
2. Old resistance desired function to calculate the required battery ampere to fit the needs of
