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, 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 IT IS OPERATING— can supply power for a limited amount of time, depending on how many batteries you have and your battery charging method.
The packages include attractive steel battery enclosures, fully wired for safety and lockable. All that is require is an Electrician that will isolate the power of the appliances you intend to power using backup solution into a sub-panel.

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.

3) Or, if you already have a solar grid-tie 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 grid-tie system’s solar panels even when the grid is down. This can be planned at the time of purchase of your grid-tie system, or it can be added later.

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 off-grid situation where there is no grid power.
