There are several stepsto the planning process so the user must determine the following:• Maximum inverter wattage required.• Operating time (run time) needed between battery recharges.• Battery bank capacity in amp-hours.• Charger requirement to charge batteries within a practical time.• Distance between battery bank and inverter.DETERMINING MAXIMUM APPLIANCE WATTAGEMaximum AC 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. Appliancepower is the AC load the inverter has to supply.Most other electrical tools, appliances and audio/video equipment have labels that list the unit’spower 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 460watts. Determine the wattage of each appliance you need to simultaneously operate. Add all ofthe appliance wattages to obtain an estimated “total watts” number. Remember to consider thestartup surge that motorized appliances will cause. Do not exceed the surge rating of this inverter(5,000 watts) this can cause immediate overload shut down.At 5,000 watts continuous output, this inverter requires a DC power supply (battery bank)that can continuously supply the following level of amps for the duration of the run time:#3744 (12V DC Input) — 500 amps @ 12V#3744-4 (24V DC Input) — 250 amps @ 24V#3744-8 (48V DC Input) — 125 amps @ 48VSIZING THE BATTERY BANKA battery bank is an interconnection of batteries; in this case, to provide 12 volts. To determinethe minimum battery ampere-hour rating that you will need to operate appliances from theinverter and any DC appliances powered by the battery bank, follow these steps:(The following calculations are specific to 12V systems. For 24V or 48V systems, a differentcalculation is required but the same principles should apply)1. List the maximum continuous wattage that an inverter has to supply.2. Estimate the number of hours each appliance will be in use between battery recharges. Thiswill vary. For example, a typical home-use coffee maker draws 500 watts during its brewtime of 5 minutes, but maintaining pot temperature only requires 100 watts. Typically, amicrowave oven only operates for a few minutes. Refrigerators and air conditioners cycleon and off. Some longer operating time appliances are lamps, televisions, computers andsound systems.3. Determine the total watt-hours of energy needed by multiplying average power consumptionin watts by hours of run time. For example: 1,500 watts for 10 hours = 15,000 watt hours.
