To Turn the Power Inverter Off:
1. On the left side panel, switch the
On/Off Switch to Off
On/Off Switch to On
The inverter is now ready to deliver AC power to your loads. If several loads are to be operated by the inverter, turn them On separately, after the inverter has been turned On. This will ensure that the inverter does not have to deliver the starting currents required for all the loads at once.
2. On the left side panel, switch the
On/Off Switch to On.

Turning Your Inverter On or Off
•
Be sure to have your power inverter properly installed before attempting to turn the unit On (see “Installation” page 5).
To Turn the Power Inverter On:
1. If a DC power supply is being used as the power source, switch it On.

Power Consumption

For each piece of equipment you will be operating from the inverter, you must determine the battery’s reserve capacity (how long the battery can deliver a specific amount of current – in automotive batteries, usually 25 amperes) or ampere-hour capacity (a measure of how many amperes a battery can deliver for a specified length of time).
Example – Reserve capacity: a battery with a reserve capacity of 180 minutes can deliver 25 amperes for 180 minutes before it is completely discharged.
Example – Ampere-hour capacity: a battery with an ampere-hour capacity of 100 ampere-hours can deliver 5 amperes for 20 hours before it is completely discharged.
To Determine the Battery Ampere-Hour
Capacity You Require:
1.Determine how many watts each piece of equipment consumes. This can normally be found on the product label. If only the current draw is given, multiply the current draw by 115 to get the watt consumption.
2.Estimate the time (in hours) that each piece of equipment will be running between battery charging cycles.
3.Calculate th total watt-hours of energy consumption (power x operating time) using the average power consumption and the total estimated running time (in hours). Power x Operating Time = Watt-Hours.
Laptop | TV/VCR (up to 25") | Blender |
100 Watts x 2 hours | 115 Watts x 3 hours | 300 Watts x 15 min |
= 200 Watt-Hours | = 345 Watt-Hours | = 75 Watt-Hours |
4.Divide the watt-hours by ten (10) to determine how many power supply’s (12 volt) ampere-hours will be consumed.
