The Sun Electronics UPSUI series of battery backup PV systems are designed to provide reliable AC electric power on a 24/7 basis, even if the utility is down. When the utility is in operation, the output of the PV system is first used to meet the needs of the customer, and then any excess electricity produced is sold back to the utility so someone else can use it. If, for any reason, the utility is shut down, the PV system will still provide power to selected customer loads, but will disconnect from the utility until the PV system determines that the utility power is is stable.  Then the PV system automatically reconnects to the utility. If the utility is down for a prolonged period, the system batteries will provide electricity to the customer emergency loads when the sun is not shining.

The systems are engineered for Florida winds by engineers experienced with the Florida environment. One of their systems in Boca Raton, FL, has now been through 4 hurricanes without missing a heartbeat. Although it is designed for a 150 mph wind, it has only been tested so far at 110 mph, thanks to Wilma in 2005. Systems in Key Largo and Tampa have also survived the hurricanes of the past 3 years. 

The choice of a noiseless, pollution-free PV system, along with State and federal (and, perhaps, utility) incentive programs, can result in the system paying for itself in less than its lifetime. After the system pays for itself, it will be making money for you through savings on your electric bills.

As a final note, the PV industry is in a constant state of change. The worldwide demand for PV, along with shortages of silicon, the basic component of the PV cell, means that not all system components will necessarily be available at all times. When you inquire about a system, we will be able to let you know whether the system is availabe immediately. We have made every attempt to mix PV modules, inverters, array mounts and batteries to enable us to always have systems to ship in the power range you wish to install. Also due to these rapid market fluctuations, the availability, prices and components listed above may change without notice.

We look forward to serving you.
