Float Charge
Once the battery is fully charged a somewhat lower Float Voltage (factory set to 13.2/26.4V) is applied to maintain the battery in a fully charged state
without excessive water loss.

EQUALIZATION
¾ WARNING: Not all batteries can be safely equalized. Equalization should only be performed on vented liquid electrolyte
lead-acid batteries. Always follow battery manufacturers recommendations pertaining to equalization. Equalization applies a
high voltage producing significant battery gassing. Disconnect equipment that cannot tolerate the high equalization voltage
which is temperature compensated.
Periodic equalization improves battery performance and life by bringing all battery cells up to the same specific gravity and eliminating electrolyte
stratification. Equalization parameters are factory set to 15.2/30.4V for 2 hours every 30 days. A minimum net charge current of approximately 3A per 100 amp-
hours of battery capacity is required for proper equalization. If insufficient current is available equalization may have to be canceled manually since the equalization
time accumulator may not complete count down.
The equalization timer is a “time at voltage” time accumulator which counts in 3 minute increments. The equalization timer will not count down unless the
battery is at the equalization voltage setpoint. Unless manually disabled the 3024 will stay in equalize for as long as necessary to accumulate the required time at
voltage. If equalize does not complete by end of the charging day it will resume where it left off the next charging day.
Automatic Equalization
If DIP switch #5 is turned ON prior to the application of battery power, automatic equalization is enabled. The 3024 will perform automatic equalization
after the set number of days has elapsed. (factory set to 30 days).
Manual Equalization
If DIP switch #5 is turned OFF, equalization is completely disabled. A manual equalize can be performed by turning DIP switch #5 ON, after battery
power is applied. Following completion of a manually initiated equalization cycle, turn DIP switch #5 OFF. If DIP switch #5 remains ON automatic equalize is
enabled. Equalization can also be controlled from the IPN-ProRemote if DIP switch #5 is ON.
CURRENT LIMIT
Automatic current limit prevents output current from exceeding 40A with 12V batteries and 12V PV’s. If PV open circuit voltage (V
OC
) ever exceeds
30V which would occur with PV voltage greater than 12V nominal, current limit will become 30A until the 3024 reboots. Note that when the 3024 exits current
limit, it will briefly enter acceptance on it’s way back to MPPT even though battery voltage may be low.
TEMPERATURE AND OUTPUT POWER
When mounted vertically as described in the installation section, the 3024 can deliver full output in an ambient temperature of up to 40 °C (104°F). If an
over temperature condition exists, the 3024 will cycle on/off, reducing average power delivery to within safe limits. During thermal shutdown the Charge Status
Indicator will display an OFF condition.
