CAUTION:
No material (such as a washer) should be placed between the current carrying
terminal and the cable lug or interconnecting busbar. Doing so will Violate the terms of the
Warranty.
CAUTION:
Sparks may be present when connecting wires to SimpliPHI Battery terminals. Be
sure the battery’s built-in circuit breaker is in the OFF position to minimize the risk of shock or
sparks during system installation.
4.6.3 – Parallel Wiring Batteries with Threaded Studs using Interconnecting 4/0 Cables
SimpliPHI Batteries can be paralleled by directly attaching 4/0 cables to the batteries’ terminals. Up to
4 batteries can be connected by daisy chaining positive to positive and negative to negative terminals.
It is recommended that 4/0 cable is used for installations of 3 or 4 batteries. For installations of 3 or
less, 2/0 cable can be used. This installation method should only be used for indoor applications.
Outdoor applications will require conduit and conduit boxes (available from SimpliPhi). Please refer to
Section 4.8 for outdoor installations.
CAUTION:
Again, no material (such as a washer) should be placed between the current
carrying terminal and the interconnecting busbars. The interconnecting busbars are placed on
the SimpliPHI Batteries’ terminals first, then the flat washer, lock washer, and nut are secured
to the terminal posts.
Helpful Tips:
•
The interconnecting cable ratings should match or exceed the SimpliPHI Battery bank’s total
surge rating.
•
Cables for paralleling more than two SimpliPHI Batteries can be sourced from outside
suppliers or custom ordered from SimpliPhi.
•
Best practice involves wiring the battery leads to opposite ends of the battery bank.
•
Size the battery cables leading from the interconnecting cables to the Balance of System
equipment using the National Electrical Code’s Conductor Ampacity tables.
CAUTION:
Do not reverse polarity. Use a voltmeter to check polarity before making
connections to the battery terminals. Reversing polarity will Violate the terms of the Warranty.
