Quick question on dump load voltage setting.
« on: February 19, 2009, 02:53:40 AM »
I have a 24 volt wind turbine system. What voltage should i have the dump controller set at? I currently have it set to dump at about 28.8volts.

What type of batteries?

How often is your system likely to be at that voltage?


28.8V is the voltage one would use to equalize lead acid batteries, therefore too high.


http://www.powerstream.com/SLA.htm for 24V just double 12v figures

  Wpowokal is right..how long will they spend at that voltage..


 I have found with my 650amp/ L16 battery bank and my 2volt 600amp/hr wet cell battries that they need to reach and hold 28 volts for a couple of hours before they are fully charged  to the hydrometer and trimetric meter.


 30 volts for equalizing until each battery is 6.5 volts.

  But my batteries rarely get to float stage because they are constantly in use.


  My TS 60 is set for the L16 setting as a dump load controller.

 MX60 is set to hit 28 volts for a absorbtion stage

 When using the genset for extended periods (like 30 days ) 26 volts for float.
