3000 Watt AC Inverter by Wagan Tech

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:

List the maximum continuous wattage that the inverter has to supply.
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 coffee maker draws 500 watts during its brew time of 5 minutes. It maintains

the temperature of the pot, requiring 100 watts. Typical use of a microwave oven

is only for a few minutes. Some longer operating time appliances are lamps, TVs,

computers and refrigerator/freezers.
Determine the total watt-hours of energy needed. This is done by multiplying

average power consumption in watts by 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 at 150 amps equals 1,500 Amp-

hours (Ah). This answer is just a beginning because there are additional factors that

determine actual run time. These include:

AC appliance load and time in use (basic Ah).
Cable gage and length (cable losses).
Charge level of the batteries (between use, chargers have to be able to

fully charge the batteries).
Temperature of the batteries (colder batteries provide fewer amps).
Age and condition of the batteries (older batteries lose Ah capacity).
Compliance with turning off unnecessary AC loads.
Use of DC appliances and compliance with turning off unnecessary DC

loads.

Derating The Battery Bank

Most lead-acid batteries have a rating expressed in amp-hours (Ah). The most common

rating of Ah is “at the 20 hour rate”.

NOTE: Despite several internet explanations, there is no relationship between Cold Cranking

Amps (CCA) and Ampere Hours (Ah).

For example; if a 20 Ah battery is discharged at a 1 amp rate, is will take 20 hours to

discharge that battery. The terms “charged” and “discharged” relate to actual battery

voltage. This means that the output voltage of a nominal 12 volt battery starts at 13.2 volts
