So despite the absorption problem remaining unfixed by the last firmware update, I'm now trying to set my SmartSolar MPPT to correctly and automatically equalize, like my previous controller did.
The Victron manual states:
"The current is limited to 8% of the bulk current for the factory default
battery type, and to 25% of the bulk current for a user defined
battery type. The bulk current is the rated charger current unless
a lower maximum current setting has been chosen."
25% of 50A is 12.5A - much more than the specified 8a limit for my batteries. If the manual is correct, does this mean I have to hamstring my 50A controller to 32A, just to get the correct equalization limit??
Additionally, the manual also states:
"For all tubular plate batteries and the user defined battery type
automatic equalization ends after t = (absorption time)/2."
Again - ignoring for the moment that Victron controllers have horribly unreliable absorption times - this "absorption time/2" again doesn't match my batteries equalization time specs, so long as I try and also use their recommended absorb time
So am I understanding these settings correctly?
If so - who's idea was it to tie equalization limits to arbitrary %-ages of absorption??? It's a roundabout method that winds up meaning unless your batteries work specifically on Victrons ratios, you're force to have one parameter or the other incorrect, or both.
If these are controllable parameters (which they obviously are), why not make it a straightforward setting, so people can just set what they need and be done with it?
