Operation
Equalization is normally performed only on flooded lead-acid batteries. The schedule for equalization
varies with battery use and type. If performed correctly, this process can extend battery life by a
considerable amount.
This function is not available for battery types that use two-stage charging or a BMS.
CAUTION: Battery Damage
Do not equalize any lithium-technology battery.
Do not equalize any nickel-technology battery.
Do not equalize any sealed battery types unless approved by the manufacturer.
Some batteries may suffer severe damage from equalization.
Contact the battery manufacturer for recommendations on equalization voltage,
duration, schedule, and/or advisability. Other battery manufacturers may
recommend a different definition of equalization than that shown above.
Always follow manufacturer recommendations for equalization.
Temperature Compensation
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. The Mojave inverter, when equipped with the Remote Temperature Sensor (RTS),
will compensate for changes in temperature. To achieve a representative temperature, the RTS is
attached to a single battery near the center of the bank. The inverter has a designated port for RTS
installation.
This function is not available for battery types that use a BMS.
If temperature compensation is not used:
When a battery is cooler than room temperature, its internal resistance goes up and the voltage
changes more quickly. This can result in the battery being undercharged.
Conversely, when a battery is warmer than room temperature, its internal resistance goes down
and the voltage changes more slowly. This can result in overcharging, which may shorten the life of
the battery.
Slope
When charging, an inverter system with an RTS will adjust the charging voltage inversely with
changes in temperature. It will
increase
the charge voltage by a certain number of mV for every
decrease of 1 degree Celsius per battery cell. Similarly, it will
decrease
the voltage by the same
amount for every increase of 1°C per cell. This is referred to as compensation “slope”. A common
slope is 5 mV/°C/cell. The slope can be set with
Temperature Compensation (mv/C)
menu item.
This setting affects the Absorption, Float, and Equalization set points. The Rebulk and Refloat
set
points are not temperature compensated. In a 48 Vdc system (24 cells, 2 volts each), this means
0.12 volts per degree Celsius above or below 25°C.
NOTE:
Temperature compensation only applies to the battery charging function. Other set points in
the inverter, such as the
A
UX
functions, are not compensated for temperature.
