INFO
1. 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:
a)
Models: (i) EVO-2212 / EVO-3012 / EVO-2224 / EVO-4024 and (ii) EVO-2212E / EVO-3012E /
EVO-2224E / EVO-4024E
•
Power Transformer Temperature > 130°C: (i) EVO-2212 / EVO-2212E: Reduce by 4A every 10
sec, (ii) EVO-3012 / EVO-3012E: Reduce by 20A every 10 sec, (iii) EVO-2224 / EVO-2224E:
Reduce by 1A every 10 sec, (iv) EVO-4024 / EVO-4024E: Reduce by 5A every 10 sec.
•
Heat Sink Temperature is > 65 °C: (i) EVO-2212 / EVO-2212E: Reduce by 4A every 10 sec, (ii)
EVO-3012 / EVO-3012E: Reduce by 20A every 10 sec, (iii) EVO-2224 / EVO-2224E: Reduce by 1A
every 10 sec, (iv) EVO-4024 / EVO-4024E: Reduce by 5A every 10 sec.
b) Models EVO-1212F, EVO-1212F-HW, EVO-1224F, EVO-1224F-HW and EVO-4248SP
•
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
2. In case external Solar Charge Controller is also charging the batteries through DC input terminals marked
"EXT Charger", the amount of Bulk Charging current producted 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.
