MPPT 100/20 Expert Equalization mode

I have a MPPT 100/20 SmartSolar controller. I am trying to get the equalization mode to last longer than 1 hour.


I have enabled expert mode, set the time to 8 hours and start an equalization but it gives me a note about 1 hour and only goes that long.


How do I get it to last for the time I specify? My battery manual calls for an 8 hour conditioning, not a 1 hour one.

I don't think you are interpreting battery manual correctly.

Please post a copy/link of your battery manual.

Very difficult to interpret this wrong... But thanks anyways.


The conditioning charge should then be applied for 8 hours. At 77°F the conditioning voltage should be set to 15.5V for a 12-volt battery.

It looks like the controller will use the set time for an automatic equalization, but not a manual one. That seems a little silly so I emailed victron about it.

The Victron settings will probably not boil your battery dry....

This is a gentle bump.

There are lots of smart ppl on the Victron Communities..

Some will actually have a strong opinion biased on their experiences..

Boiling the battery dry really is not a concern for me with my battery type, the issue is more that expert mode is limited in it's operation when it shouldn't be.


Assuming boiling the battery dry was a concern, its more likely with how they have it setup now since I could could have the automatic enabled to occur for up to 14 hours a day every day, vs the manual mode would only be when manually started.
