This section is included in your selections.

The starting system shall consist of a 24-volt battery system. The battery set shall consist of two heavy duty 12-volt, lead-acid batteries designated for such a use. The battery set shall preferably be located within the engine/generator set base.

Since the engine/generator set seldom runs long enough to maintain a full charge on the starting batteries, an adequately sized automatic battery charger of the solid state type shall be provided in a NEMA 4X pedestal mounted enclosure located near the engine/generator set. The charger shall be of the constant voltage, current limiting type. The charger shall float-charge the batteries and also provide an equalized charge. The battery charger shall include the following additional features: DC voltmeter and ammeter, AC input circuit breaker, DC output fuse, charger failure alarm contacts, and LED indications for AC input power “on,” charge mode, and equalize charge mode.
