Back-up Power for Emergency and Essential Loads |
|
|
A well designed stand-alone solar electric system will supply electricity come rain or shine. That kind of independent, or off-grid, system stores energy for nights and cloudy days in a bank of batteries. However, those of us with grid-intertied electric systems or houses and businesses which totally rely on the local utility company lose all power during a temporary blackout or when weather damage knocks out power lines for days.
|
|
With a Back-up Power System, even when the grid goes down, you can still have power for essential electrical loads.....with or without an alternate source of power. Back-up Power Systems rely on a bank of batteries to store enough energy to power certain appliances. The kind of Back-up Power System you choose will depend on how you plan to charge your batteries. See diagram of Back-up power components.

The Basic Backup Power Packages contain battery banks which are automatically charged by grid power when it is available. If the grid goes down, you draw power out of the batteries to run your essential appliances.
When the grid is down, you have the option of re-charging your batteries with a generator of your choice or with solar panels (see Solar Options below).
The amount of back-up power available is determined by the number and storage capacity of your batteries. In the systems priced above, four or eight UPG 6 volt batteries supply 4,800 to 9,600 watts of electricity, or enough to run an energy-efficient refrigerator, lights, and communication equipment for one or two days. You can increase the storage capacity of your Back-up Power System with our Battery Add-on Packages.
See this power usage chart of common appliances to help you determine your storage needs.

NOTE:
Adding solar panels to your Back-up Power System qualifies you for a $2,000 Federal tax credit, as well as solar rebates in many states. |
The addition of solar panels to your Back-up Power system allows you to re-charge your battery bank when power lines are down and when obtaining gasoline for a gas generator is impossible or undesireable.
This is a necessary add-on for emergency back-up power in areas that get hit by hurricanes. We also sell the Basic Back-up Power Package with Solar Option 1 or 2 for off-grid living in cabins, boats and RV's.
This is easy, affordable energy independence! |
