For equalizing to work the bank should be fully charged first. 100W solar won't fully charge 130AH bank discharged to 50-60%. So your automatic 28-day equalizing might not happen when you need it.
100W solar generates 25-30AH a day max. Unless your are cycling very lightly (doesn't sound like it is), 100W solar leaves your 135 AH bank undercharged and need equalizing maybe more than once in 28 days - but you might not be getting this automatic equalizing at all (see the previous paragraph).
Charge it fully at home whenever possible.
