What is battery backup power?

Back-up power allows you to continue using certain (or all) appliances when utility provided grid electricity is not available.

If a hurricane knocks out the power lines, if there are rolling black-out's, or if you simply want to disconnect from the grid, a back-up power system with a bank of batteries which can be kept charged - with solar panels or gas generator or wind generator OR BY THE GRID WHEN IS IT OPERATING - can supply power for a limited amount of time, depending on how many batteries you have and your battery charging method.

Look at complete back-up power systems.

Your choices are, in order of complexity and cost:

1) Install a Emergency Battery-Based Back-Up System which can be kept charged by the grid when the grid is on line. This system will provide power until the batteries are depleted.

2) Install a battery-based backup system which can be kept charged with either grid or gas generator or solar panels. This can work in a home or business that has grid power or in an offgrid situation where there is no grid power.

3) Or, if you already have a solar gridtie electrical system, you can install a battery-based backup system which can be kept charged with the grid, when grid electricity is available, or with your gridtie system’s solar panels even when the grid is down. This can be planned at the time of purchase of your gridtie system, or it can be added later.

System Components
Solar PanelSolar electric panels—a.k.a. solar modules, photovoltaic (PV) panels
Pointed towards the sun, solar panels capture the energy in sunlight and convert it directly to DC electricity. There are three general families of solar panels on the market today—single crystal silicon, polycrystalline silicon, and thin film. More on the different types.....

PV modules are very durable and, because there are no moving parts, long-lasting. Most carry 25 year warranties. Solar panels are assigned a rating in watts based on the maximum power they can produce under ideal sun and temperature conditions per hour. You can use the rated output to help determine how many panels you need. Multiple modules mounted together are called an array.

Solar Panels Mounting RacksArray Mounting Rack—a.k.a mount, racks, trackers

Mounting racks provide a secure platform to keep your panels fixed in place and oriented correctly. Panels can be mounted on your roof, atop a steel pole set in concrete, or at ground level. The type of rack you choose will vary considerably depending on your budget, climate, building codes, and personal preferences. In areas where it snows a lot, you may want to be able to sweep the snow off periodically.

DC DisconnectArray Combiner/DC Disconnect
The DC disconnect is used to safely interrupt the flow of electricity from the array of solar panels. It is an essential component when system maintenance or troubleshooting is necessary. The disconnect enclosure houses an electrical switch rated for use in DC circuits. It also may integrate either circuit breakers or fuses, to combine the electricity of multiple sub arrays of solar panels.
