BULK CURRent:
This sets the maximum charging current during the Bulk Charging Stage. The default value is 40A.
Normally, Lead Acid batteries should not be charged at very high Bulk Charging Current as this
will damage the batteries due to overheating and cell degradation. Normal Bulk Charging Current
is in the range of 10% to 20% of the Ah capacity of the battery bank at C/20 Discharge Rate.
Check with the battery manufacturer regarding recommended Bulk Charging Current for your
battery bank. This value of "Bulk Charging Current" should be programmed as "Bulk Current".
Please refer to Section 5.4 in the owner's Manual for eVo
External Solar Charge Controller is also charging the batteries through DC input terminals
marked "EXT Charger" (3,4 in Fig 2.1 in Owner's Manual for Evolution
Charger), the amount of Bulk Charging Current produced by the internal Battery Charging
Section is adjusted in real time to satisfy the following condition:
• I nternal Bulk Charging Current = Programmed Value of "Bulk Current" – External Charging Current
For example, if the "Bulk Current" in the EVO
of 40A and the external Solar Charge Controller is generating 15A, the internal Battery
Charging Section will reduce its current from 40A to 25A so that the net charging current is
equal to the programmed "Bulk Current" value of 40A

1. In order to protect against over temperature shut down when operating in higher
ambient temperatures of 50C to 60C, the charging current is automatically
reduced as follows based on temperature sensed at the Power Transformer and at
the Heat Sink for the Power Mosfets:
• Power transformer: In cast the temperature is >130C, the charging current is
reduced by 4A (EVO-2212) / 20A (EVO-3012) / 1A (EVO-2224) / 5A (EVO-4024)
