TECHNICAL INFORMATION

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. Equivalent to water pressure in a hose.

Watts - Measure of power output or utilization. Watts = Volts x Amps.
