Using Inverters for Back-up Power...
An inverter converts stored battery power to 220 VAC. In a renewable energysystem, such as a solar or wind system, inverters are used to provide power inremote locations. But the same equipment can be used to provide power to backupequipment found in offices, suburban homes or at your desk.What do I need to build a backup system?There are four components to a back-up system:
| Component |
Sizes |
Notes |
| Inverter |
300 W to 10 kWr |
Output greater than largest AC load |
| Battery |
5 to 150 amps |
Recharge batteries in 8-16 hours after discharge |
| ChargerBattery |
50 to 2000 AH |
Sized to run loads for 1-48 hours |
| Auto-Transfer |
5-50 amps AC |
To switch to back-up power in event of power loss |
Choose a Back-up System that includes an inverter with transfer switch andbattery charger with enough power to handle the type of equipment you wantto run. If you dont know how much power youll need, see the table on Page 2.The battery bank is selected with enough reserve storage to power yourequipment for as long as needed, typically one to 48 hours. GES or its Dealerscan calculate the battery bank size, if you need advice. Note that many of theinverters we offer have built-in automatic transfer switching to detect a powerfailure and connect the inverter to the load circuits. If some of the loads youwish to run are sensitive to power output quality, you may elect to use a puresine wave inverter.
How do I install a Back-up Power System?
A Back-up Power System consists of an inverter, with a battery charger and battery bank. Smaller systems can beinstalled near the loads they will run - i.e. the computer or the furnace. Larger systems are typically installed in abasement or garage, near the electrical panels.The electrical circuits that are to be run from the inverter must be separated and wired through the inverter. Forhome backup systems, a small AC sub-panel for the emergency loads can be installed next to the main panel (asshown above). Dont forget to enclose the batteries and vent them to the outdoors. GES has designed manyback-up power packages for different applications. If you have any questionsabout the choice of a system to fit your needs, please contact GES or your localDealer.
Home & Commercial Back-up Systems...
Our home and commercial Back-up Systems can protect your home orbusiness from power failures. With sizes from 300 to 10,000 watts, they canrun sensitive loads of all sizes. Install with any of our Solar-Series BatterySystems and you can have four to 48 hours of protection.Back-up Systems can be as simple as a hand-held inverter, or a completelyautomatic system connected to the electrical panel. To simplify installation, weoffer fully integrated panels with inverter, charger and transfer switching.
