Back-up Power for Emergency and Essential Power Loads

As we have learned over the years, 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. Houses and businesses which totally rely on the local utility company lose all power during a temporary blackout or when weather or earthquake 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. You just charge the batteries with the normal AC current or with other sources, such as solar or wind power generators. Back-up Power Systems rely on a bank of batteries to store enough energy to power certain appliances and circuits. The kind of Back-up Power System you choose will depend on how you plan to charge your batteries and how much energy you need to store. See diagram of Back-up power components

Backup Systems Prices

Here are our two basic Battery Backup Systems, both can be adapted to the PRIS system and/or solar charging.

Backup sys 19200 watts storage with delivery of 4.4 kw per hr at 110 - 220 volts AC with 48volt battery bank Inverter, charger, 8 batteries, connectors, etc. $10,500

Backup sys 9600 watts storage with delivery of 4.0 kw per hr at 110-220 volts AC with 24volt battery bank Inverter, charger, 4 batteries, connectors, etc. $8,000

We use the Magnum Energy sine wave inverter, Midnight Solar Epanel, complete with lightening arresters, circuit breakers, disconnect switches, and an automatic switching circuit that goes to battery power in a microsecond of loosing grid power.

The batteries are Rolls S520 400 amp hour, 6 volt batteries. These are the best we can find with an expected life of 15 years and guaranteed for 7 years.

We can help you to figure out what outlets, lights and other circuits should be protected from brownouts and blackouts. The converter (inverter) equipment we use now allows us to have 110 or 220/240 clean power available from the batteries. In a grid connected house, these circuits usually include an outlet and light in each room or area that need lights, power to security and communications, power to refrigerators and water supply pressure pumps, etc. These circuits are located usually in their own breaker box.
