Determining The Maximum Appliance Wattage
Maximum Appliance Wattage is the first factor in planning battery and charging systems.
Some background:
Large microwave oven specifications list cooking power (watts) and appliance power. Appliance
power is the AC load the inverter has to supply.
Most other electrical tools, appliances and audio/video equipment have labels that list the unit’s
power requirements in watts. If the tool or device is rated in amps, multiply the amps by 115 (115V
AC) to determine the watts. For example, a power tool rated at 4-amps will draw 460 watts.
Determine the wattage of each appliance you need to simultaneously operate. Add all of the
appliance wattages to obtain an estimated “total watts” number. Remember to consider the start-
up surge that motorized appliances will cause. Do not exceed the surge rating of the inverter.
At 8,000 watts continuous output this inverter requires a DC power supply (battery bank) that can
continuously supply 800 amps at 12V DC for the duration of the run time.
Configuring the Battery Bank
To determine the minimum battery ampere-hour rating that you will need to operate appliances
from the inverter, and any DC appliances powered by the battery bank. Follow these steps:
1. List the maximum wattage that the inverter has to provide (as above).
2. Estimate the number of hours the appliances will be in use between battery recharges. This
will vary depending on appliances. For example, a typical home-use coffeemaker draws 500
watts during its brew time of 5 minutes, it maintains he temperature of the pot at about 100
watts. Typical use of a microwave oven is only for a few minutes. Some longer operating time
appliances are lamps, TV’s, computers and refrigerator/freezers.
3. Determine the total watt-hours of energy needed. This is done by multiplying the average power
consumption in watts by the number of hours of run time. For example: 1,500 watts for 10 hours =
15,000 watt hours.
To get an estimate of the maximum current (in amps) that a battery bank must be capable of
delivering to the inverter, divide the load watts by ten. For example a 1,500 watt appliance load
will need 150 amps at 12 volts DC.
Using the 1,500 watts (or 150 amps) for 10 hours example as above, then 150 amps is needed
for 10 hours. This provides us with the basic amp-hours (AH) of battery that is required. Ten hours
