Assembled, wired and tested by the FOUR STAR SOLAR, this Four Star Backup 2000 unit incorporates an inverter that monitors the grid. If the grid goes down or is disconnected, it will switch to battery backup in less than a second, keeping your critical loads online (powered by batteries) until the grid comes back. 

The Four Star Backup 2000 has four 200 aH UPG batteries, with the option of adding more. See Battery Option below. The heart of the the system is a Magnum MS2012 2,000 watt sinewave inverter. Also included are Magnum Battery monitor, battery enclosure with two shelves, all necessary battery interconnects and terminal caps. 

A selling point for this simple backup system is that it includes an AC plug, which allows you to plug an extension cord or appliance directly into the unit for quick restoration of power to specific items.

The Four Star Backup 2000 does not include solar panels, but they can be added. See Solar Add On option below.

The battery bank of the Four Star Backup 2000 can be charged with grid electricity (while it is available), or by generator or solar panels when the grid is down.

Applications
Four Star Solar’s 120 volt battery backup systems can be used to power a mixture of security and lighting appliances.
