#980-00080-01-001 REV B
*Use appropriate wire size in accordance with NEC.
Low Voltage Charge Controller Advantage—Smaller string size reduces power output loss in the event of inadvertent module shading
OutBack Power FLEXmax 80 Charge Controller
Lower Voltage Four-String, 3780W Array (315W Modules)
Shading of a single module affects one string, resulting in a
power output loss of up to 25%
Competitor Charge Controller
Higher Voltage Two-String, 3780W Array (315W Modules)
Shading of a single module affects one string, resulting in a
power output loss of up to 50%
