Devices
The DC circuit from the battery to the
inverter/charger must be equipped with a
disconnect and overcurrent protection device.
Refer to your applicable installation code for
guidance.
Type
This device usually consists of a circuit
breaker, a “fused-disconnect,” or a separate
fuse and DC disconnect. Do not confuse AC
circuit breakers with DC circuit breakers. They
are not interchangeable.
Rating
The rating of the fuse or breaker must be
matched to the size of cables used in
accordance with the applicable installation
codes.
Location
The breaker or fuse and disconnect should be
located as close as possible to the battery in
the positive cable. Applicable codes may limit
how far the protection can be from the battery.
Recommended Fuse Size
350 A
Based on National Electrical Code (NEC) requirements. The NEC requires that
the cables be protected by a fuse or breaker rated to match the cables’ ampacity
at 75 °C.
