Page 3: System Design
Renewable Energy applications that depend on battery power as part of the system operation must be at maximum performance at all times. To ensure this high rate of performance is achieved, the battery charging system must be set properly. A battery/battery bank that is undercharged or overcharged will affect the battery system performance &... -

Page 6: Series/Parallel Wiring
Series/Parallel Wiring Series and parallel wiring of batteries as well as battery to inverter/charge controller wiring should be designed to minimize voltage drop. Wire gauge, wire length as well as interbattery connection layout are all variables in reducing volt- age drop as well as providing battery balance between parallel battery strings. -
