Multiplus Compact 24/2000 Trojan T125

1642786125135.png

We have a Multiplus Compact with a house bank of 8 Trojan T125's in a 24V series/parallel configuration.

How to configure the Equalisation Voltage?

With VEconfig we are able to set the Absorption and Float voltage, the Equalisation voltage is a fixed voltage 2V above Absorption (according to the Multiplus manual).

According the Trojan recommendations this is not OK for the T125.

If we set Absorption to 29.4 the Equalisation will be 31.4 instead of the recommended 32,4V

And Trojan recommends a 2-4 hour equalisation.


Thanks,

Peter

Trojan recommends equalization only when SG is below a certain threshold or variation between cells exceeds 0.03. As such, equalization should only be done manually after you've confirmed that they need equalization after checking all 24 cells.


Since it's a manual operation, you could simply set the absorption to 30.4 before you engage the equalization charge.
