UDCZERO ENERGY VISTOR

CENTER

System Components• Solar Array

– Primary Power Generator– Array consists of 12 BP SX3190B Solar Modules

System Components• BP SX3190B

– 190 Watts, 24.4 Vdc– 25 year warranty

System Components

• Charge controller– Regulates charging current from the solar array to the battery– FlexMax 60 Outback Charge Controller

System Components

• FlexMax 60 Outback Charge Controllers– MPPT charge regulation can increase Array production by as

much as 30%– Extensive electronic protection against reverse polarity, high

temperature and over current

System Components

• Battery bank– Supplies a stable power source since the Solar Array current

varies by time of day and weather condition– 8A8D SLA AGM Deka Battery

System Components

• 8A8D SLA AGM Batteries– 12V 265 AH of capacity at the 20Hr rate– High capacity, reliable, durable, and deep cycle capacity for

heavy demand applications

System Components• Inverter

– Converts power stored in batteries from Direct Current (DC) to Alternating Current (AC) for use with standard equipment

– Also allows excess power generated to be sold back to the utility grid

– GVFX 3648 Outback Inverters

System Components• GVFX3648 Outback Inverter

– Simple modular design for true sine wave power

– Grid interactive or standalone capability– 2 units stacked for 120/240 VAC

System Components

Wind Power• Usually not a primary power source• Complements solar power

– Reduces depth of discharge during inclement weather– Fairly inexpensive depending on mounting option

• AIR Breeze 48vdc wind turbine

System Components• AIR Breeze 48vc

– 35Kw monthly output in 12mph avg. wind– Built in charge regulation

System Design

System Design• Off Grid/Utility Tie with Battery Back Up

– Allows for Stand Alone operation– Also allows for buying and selling power to

and from the Utility

Inspection

Inspection

• Solar Array– Check physical condition of solar modules

• Unbroken glass• Relatively clean• Straight frames with no corrosion

– Verify module frame grounding– Check mounting hardware for loose fasteners– Confirm that all module junction box covers are

present– Electrical tests

• Open circuit voltage for each module or module string• Short circuit current for each module or module string• Variations in excess of 10% should be investigated

Maintenance

Maintenance• Scheduled Maintenance

– Annual maintenance• Schedule in the fall so that the system will provide

optimum performance in the winter months

– Clean solar array if necessary• Water and mild soap are recommended• Do not use any abrasives

– Perform complete inspection• See previous section• Make adjustments or repair as necessary
