Figure 4.2 – Four SimpliPHI Batteries in Parallel
For installations that are larger than 4 batteries, equal sets of batteries not exceeding four batteries per set
should be wired to a common busbar or plate. All wire lengths from each SimpliPHI Battery Bank to common
busbars or plates should be
identical in length and gauge
in order to balance the load across (all) SimpliPHI
Batteries in the installation.
CAUTION:
Identical wire lengths and identical wire gauges from each SimpliPHI Battery in an
SimpliPHI Battery bank is a critical feature of parallel power storage systems that must be
adhered to throughout all parallel wiring instructions. Failure to properly wire the SimpliPHI
Batteries in parallel will Violate the terms of the Warranty.
Figure 4.3: Three SimpliPHI Battery Banks wired in Parallel to a terminal block. This configuration requires 6
identical lengths of identical gauge copper wire.
Helpful Tips:
•
Power cabling for paralleling SimpliPHI Batteries is not included. All wire should be an appropriate
gauge and construction to handle the loads that will be placed upon it. Heavy gauge, high strand copper
wire is the industry standard due to its stability, efficiency and overall quality.
•
Each PHI Battery’s individual wire runs are typically sized at
2/0 for banks less than 3
and
4/0 for
banks 3 or larger
, according to the 100A built-in breaker.
•
Conductor ampacity can be determined using National Electrical Code tables.
•
Depending on the electrical code of the local Authority Having Jurisdiction (AHJ), the SimpliPHI
Battery leads’ gauge may need to be sized according to the built-in breaker or according to the
SimpliPHI Battery’s surge rating.
