OPEN CIRCUIT VOLTAGE/WIRE AND DISCONNECT SIZING

Maximum Open Circuit Voltage (Voc)

• Voc is the unloaded voltage generated by the solar array.

141 VDC

MX60 suspends operation to protect components

150 VDC

max open circuit voltage with the coldest environment (although the MX60

shuts down at 141 VDC, it can absorb up to 150 VDC from the array; anything higher than 150 VDC will damage the MX60)

As every brand of panel is different, be sure to know the manufacturer’s specifi cations.

Local temperatures vary seasonally and will affect panel voltage.

Hot weather: lower open circuit voltage/lower maximum power point voltage

Cold weather: higher open circuit voltage/higher power point voltage

Allow for ambient temperature correction using the following table:

25° to 10° C (77° to 50° F)

multiply by 1.06

9° to 0° C (49° to 32° F)

multiply by 1.10

-1° to -10° C (31° to 14° F)

multiply by 1.13

-11° to -20° C (13° to -4° F)

multiply by 1.17

-21° to -40° C (-5° to -40° F)

multiply by 1.25

Check the PV array voltage before connecting it to the MX60.

Wire and Disconnect Sizing

The output current limit of the MX60 is 60 amps.

Use a minimum of 6 AWG wire for the output between the MX60 and the batterry bus bar con- ductors; a larger size might be required due to temperature and/or conduit fi ll corrections.

Install OutBack OBDC-60 or OBDC-80 amp breakers for disconnect and over current protection.

The largest PV array that can connect to an MX60 should have a rated short-circuit current of 48 amps STC (Standard Test Conditions).

Input conductors and circuit breakers must be rated at 1.56 times the short-circuit current of the PV array. OutBack OBDC 100% duty continuous breakers only need to be rated at 1.25 times the short-circuit current.

Please see the wire Distance Chart and complete Wire and Disconnect Sizing on pages 80-82 for other suitable conductor/wire sizing.
