Epever DR3210N-DDS - AES Signal Port

7
Condition1: BATT2 starts charging when BATT1 reaches the float charging stage,
and the BATT2 voltage is lower than the "Charging Return Voltage.
Condition 2: BATT2 starts charging when the battery's total charging current is
higher than 3A and the BATT2 voltage is lower than the "Charging Return Voltage.
4) Stop Charging Conditions
Condition 1: BATT2 stops charging when the PV voltage is no higher than 2Vof the
BATT1.
Condition 2:BATT2 stops charging when BATT1 is not in the float charging stage and
the total charging current for the battery is less than 2.5A.
Condition 3: BATT2 stops charging when BATT2 reaches the "Full Voltage."
CAUTION
After the BATT2 charging is turned off, it will be recharged only when
the start charging conditions are satisfied.

1.6 AES Signal Port
1) AES port working principle
 The AES signal is turned on after the BATT1 voltage reaches the Boost Charging
Voltage or Equalize Charging Voltage for 5 minutes.
 The controller checks if the BATT1 charges in the boost, equalize, or float stage
every 5 minutes. The interval is the delay time for turning off the AES signal, set via
PC software (default 5 minutes, ranging from 0 to 999 minutes). The AES signal
control is turned off if the BATT1 is not in the charging stage five times.
