See manual p23
(note copper wire only)
The distance between the battery bank and the GP-ISW should be as short as possible to achieve maximum efficiency and to reduce fire hazards. The size of the cable should be thick enough to limit the voltage drop to less than 2% when carrying the maximum input current to prevent frequent low-input voltage warnings and shutdown. Only use high quality copper wire.
For greater efficiency, the cables should be as short as possible. The combined cable length should be no more than 10ft (3m). Keeping your wire runs as short as possible helps to prevent: low voltage shutdowns and nuisance tripping of the DC breaker because of increased current
draw. The table below shows the recommended DC cable size, fuses/circuit breakers and DC grounding cable sizes for the GP-ISW (Note: these values are correct for cables in free air, not conduit)
