PS Series Inverter/Charger
Part No. 3597
Rev. D: November 23, 1999
Stacking:
Series - Two inverters operating together to produce twice the power and voltage of a single inverter.
Required when operating 240 VAC loads and separate 120 VAC loads from either inverter.
Parallel - Two inverters operating together to provide twice the continuous and surge capacity on a
single output circuit. Required when a single load is too large for one inverter.
The units must be stackable, and an interface cable must be utilized. See the manual for details on
stacking if it is an option.
Stratification - Over time, a battery’s electrolyte (liquid) tends to separate. The electrolyte at the top of
the battery becomes watery while at the bottom it becomes more acidic. This effect is corrosive to the
plates.
Sulfating - As a battery discharges, its plates become covered with lead sulfate. During recharging, the
lead sulfate leaves the plates and recombines with the electrolyte. If the lead sulfate remains on the
plates for an extended period of time (over two months), it hardens, and recharging will not remove it.
This reduces the effective plate area and the battery’s capacity.
Temperature Compensation - Peak available battery voltage is temperature dependent. As ambient
temperatures fall, the proper voltage for each charge stage needs to be increased. An optional
temperature-probe (BTS) automatically re-scales charge-voltage settings to compensate for ambient
temperatures. The compensation slope based on cell voltage is -2.17 mv per degree Fahrenheit (30
mv per degree Celsius) per cell for lead-acid batteries.
Voltage - The pressure of electrical flow. Similar to water pressure in a hose.
Watts - Measure of power output or utilization. Watts =Volts x Amps.
