PHI 3.8 24V & 48V Battery Manual

REV073019

| 7 |

Each PHI Battery contains circuitry that protects the Lithium Ferrous Phosphate cells from

overcharge, over-discharge and extreme load amperage. If the values specified are exceeded,

the protective circuitry will shut down the flow of electricity to/from the PHI Batteries. In some

cases, this will result in the need to re-initialize an inverter charger. Often, inverter system

settings will be saved within the inverter memory storage and will not need to be reset. This is not

an absolute standard but is common amongst most inverter chargers and should be anticipated if

the PHI Batteries go into a state of self-protection and shut down the flow of electricity. Refer to

SimpliPhi’s inverter integration guides for inverter charge controller settings or contract the

inverter manufacturer directly.

1.2.4 – PHI Battery Connection Terminals

The largest PHI Battery sizes are equipped with two 3/8’’ threaded studs with a lock washer and

nut. The red colored high temperature molded insert connection is for the positive lead. The black

colored high temperature insert connection is for the negative lead.

CAUTION:

Do not attempt to loosen the large brass nut at the base of the terminals; doing so will

damage the PHI battery and void the Warranty.

The two smallest PHI Battery sizes are equipped with SB 50 Anderson connectors utilizing P/N

5900 #6 HD contacts.

•

12V connections are YELLOW

•

24V connections are RED

CAUTION:

Do not reverse polarity. It will void the Warranty. Use a volt meter to check polarity before

connecting terminals.

Water Resistant Cable Boots are also included and will be in place when your units arrive. The

boots are to be placed over the cable terminations and will stretch to form a water-resistant seal

around the base of the molded inserts and terminal connections.

1.3 – Explosive Gas Precautions

This equipment is not ignition protected. To prevent fire or explosion, do not install this product in

locations that require ignition-protected equipment. This includes any confined space containing vented

batteries, or flammable chemicals such as, natural gas (NG), liquid petroleum gas (LPG) or gasoline

(Benzine/Petrol).

Do not install in a confined space with machinery powered by flammable chemicals, or storage tanks,

fittings, or other connections between components of fuel or flammable chemical systems.
