Depending on the PV Array wiring and battery size, the
recommended fuse and cable gauge will depend on the actual
amps flowing through the cable. The following chart accounts for
less than 3% voltage drop and may not account for all configura-
tions.
*Panel connection assumes series to meet 24V system
minimum setup.
Larger wire sizes generally improve performance, whereas
smaller wire sizes may reduce performance, especially if
undersized. When considering wiring, fusing, and connection
options, think big and short as possible as heavier components
and shorter wire length offer less resistance and voltage drop.
Terminal Size Limitations may apply.
