will always run for the full Absorption period if the batteries dropped below the appropriate voltage 
for that amount of time.  If significant battery drain caused them to drop below the set points for 
doubling or quadrupling the rate, it may run for the full Absorption period even after a lesser amount 
of time. 

The rest of the charging stages will proceed as described on the previous few pages. 

Equalization is a controlled overcharge that is part of regular battery maintenance.  Equalization 
brings the batteries to a much higher voltage than usual and maintains this high voltage for a period 
of time.  This has the result of removing inert compounds from the battery plates and reducing 
stratification in the electrolyte. 

This process must be started manually using the system display.  The inverter cannot be programmed 
for automatic battery equalization.  This is a safety measure. 

Equalization follows the same pattern as standard three-stage charging, as shown in Figure 5.  
However, instead of the Absorption voltage set points, it is controlled by the equalize set point or  
Equalize Voltage settings in the system display.  The time is controlled by the equalize time period or 
Equalize Time setting. 

Equalization is normally performed only on flooded lead-acid batteries.  The schedule for equalization 
varies with battery use and type, but it is usually performed every few months.  If performed correctly, 
this process can extend battery life by a considerable amount.   

Equalization is not normally performed on nickel-technology batteries or any sort of sealed battery.  

¾  Do not equalize any sealed battery types (VRLA, AGM, Gel, or other) unless 

approved by the manufacturer.  Some batteries may suffer severe damage 
from equalization. 

¾  Contact the battery manufacturer for recommendations on equalization 

voltage, duration, schedule, and/or advisability.  Always follow 
manufacturer recommendations for equalization.   

  

Battery performance will change when the temperature varies above or below room temperature 
(77°F or 25°C).  Temperature compensation is a process that adjusts battery charging to correct for 
these changes. 

When a battery is cooler than room temperature, its internal resistance goes up and the voltage 
changes more quickly.  This makes it easier for the charger to reach its voltage set points.  However, 
while accomplishing this process, it will not deliver all the current that the battery requires.  As a result, 
the battery will tend to be undercharged.   

Conversely, when a battery is warmer than room temperature, its internal resistance goes down and 
the voltage changes more slowly.  This makes it harder for the charger to reach its voltage set points.  
It will continue to deliver energy as time passes until the charging set points are reached.  However, 
this tends to be far more than the battery requires, meaning it will tend to be overcharged.
