2.1.9 Over Discharge Protection
The over discharge protection control enables or disables the over discharge protection system
(ODP) and allows adjustment of the AC transfer voltage. The purpose of the ODP system is to protect
the batteries from being over-discharged. The over discharge protection control is turned clockwise to
activate the circuit. It is defeated by turning the control fully counterclockwise. If the over discharge
circuit is defeated, the inverter itself is protected from low battery voltage conditions by an additional
low battery protection circuit which has a threshold of 8.2 volts DC.
2.1.10 Battery Bank Capacity
The battery capacity control is used to inform the inverters microprocessor about the size of the
battery bank being used. The microprocessor uses the formula of "battery capacity/40" to determine
what current level the bulk/absorption charge terminates (a maximum time of 12 hours is allotted for
bulk/absorption charge) and the float charge begins. This allows the inverter to make better "over
discharge protection" and battery charging decisions. Battery bank size is adjustable from 50 to 1000
(1K) amp hours. Set this adjustment to the setting closest to the size of your battery bank (in amp
hours).
Note: .37K = 370 amp-hours, .5K = 500 amp-hours, 1K = 1000 amp-hours.
