Parameter Setup
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
TM
Inverter/Charger.
In case
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
TM
Series Inverter/
Charger), the amount of Bulk Charging Current produced by the internal Battery Charging
Section is adjusted in real time to satisfy the following condition:
• Internal Bulk Charging Current = Programmed Value of “BULK CURRENT” – External
Charging Current
For example, if the “BULK CURRENT” in the EVO-1212F is programmed at say the default
value of 20A and the external Solar Charge Controller is generating 15A, the internal Battery
Charging Section of EVO-1212F will reduce its current from 20A to 5A so that the net
charging current is equal to the programmed “BULK CURRENT” value of 20A

INFO
In order to protect against over temperature shut down when operating in higher
ambient temperatures, the set value of “BULK CURRENT” is automatically reduced as
follows based on temperature sensed at the Power Transformer and at the Heat Sink
for the Power Mosfets:
1. Models: EVO-2212, EVO-3012, EVO-2224 and EVO-4024
•
Power Transformer Temperature > 130°C:
(i) EVO-2212: Reduce by 4A ev-
ery 10 sec, (ii) EVO-3012: Reduce by 20A every 10 sec, (iii) EVO-2224: Reduce
by 1A every 10 sec, (iv) EVO-4024: Reduce by 5A every 10 sec.
•
Heat Sink Temperature is > 65 °C: (i) EVO-2212:
Reduce by 4A every 10
sec, (ii) EVO-3012: Reduce by 20A every 10 sec, (iii) EVO-2224: Reduce by 1A
every 10 sec, (iv) EVO-4024: Reduce by 5A every 10 sec.
2. Models EVO-1212F, EVO-1212F-HW, EVO-1224F and EVO-1224F-HW
•
Power Transformer Temperature > 130°C:
Reduce by 0.2% every 20 sec
•
Heat Sink Temperature is > 90 °C:
Reduce by 0.2% every 20 sec
