3.4 Power Connection
Wire size
The four large power terminals are sized for 14 - 2 AWG (2.5 - 35
mm
2
) wire. The terminals are rated for copper and aluminum
conductors. Use UL-listed Class B 300 Volt stranded wire only. Good
system design generally requires large conductor wires for solar module and battery
connections that limit voltage drop losses to 2% or less.
Minimum Wire Size
The table below provides the recommended minimum wire size allowed for the charger.
Wire types rated for 75°C and 90°C are listed.

Overcurrent Protection and Disconnects
CAUTION: Circuit breakers or fuses must be installed in both battery and solar
circuits.
The battery circuit breaker or fuse must be rated to 125% of the maximum current or
more. The recommended breaker/fuse rating for use with the charger is listed in the
below table.
Recommended breaker rating:
Minimum battery circuit breaker/fuse rating
1.25 x 60 Amps = 75.0 Amps
A disconnect is required for the battery and solar circuits to provide a means for
removing power from the charger. Double pole switches or breakers are convenient for
disconnecting both solar and battery conductors simultaneously.
