SimpliPhi PHI 1.3 Installation Manual page 8

Table of Contents

For all installations:

•

Maintain identical wire lengths from each PHI 1.3 Battery terminal to the common bus.

•

Use identical wire construction from each PHI 1.3 Battery terminal to the common bus.

All PHI 1.3 Batteries are designed to serve at a fixed voltage range in parallel arrangements for

maximum available amperage and storage capacity. PHI 1.3 Batteries are not designed to be

arranged in series for increased voltage. Series arrangements can result in damage to the PHI

1.3 Battery's protective circuitry and will void the Warranty.

4.1.2 – Increasing Storage Capacity & Simple Parallel

Arrangements

Storage Capacity and total available Amperage is increased incrementally with the number of

units in Parallel arrangements. The following illustration (Figure 1.0) shows two PHI 1.3 Batteries

in Parallel. For example, assume that these are 24V PHI 1.3 Batteries.

Note: The overall Voltage range is not changed. The arrangement remains at 24 Volts, the

available AH capacity (ability to provide 24 Volt power over time) has also been doubled with the

addition of a second PHI 1.3 Battery. The available amperage from the system has been doubled.

The same configuration should be applied to other parallel arrangements, whether they are 24V

or 12V. See Figure 2.0.

CAUTION:

PHI 1.3 Batteries are designed for parallel operation only. Do not arrange in series for

increased voltage. Wiring in series will void Warranty.

Figure 1.0 represents two PHI 1.3 Batteries in Parallel. Wire lengths from PHI 1.3 Batteries

should be identical in length and gauge in order to balance the load across (all) PHI 1.3 Batteries

in the installation. Identical wiring length is a critical feature of parallel power storage

systems that must be adhered to throughout all parallel wiring instructions.

Special attention should be paid for parallel installations. Correct wiring is essential to ensure

optimum performance and system longevity. All wire "runs" should utilize identical wiring gauge

and identical wire lengths between PHI 1.3 Batteries and the common negative or positive

"Bus" or Load. Figure 2.0 depicts four PHI 1.3 Batteries that have been wired in Parallel. This

configuration requires 8 identical lengths of appropriately heavy gauge copper wire.
