If your regularly seeing 20 odd amps going in then I would say you have enough panels but you are running your batteries down too much and need more storage, as they must be getting low by morning........................
When I was doing my research into a MPPT controller I dismissed the Victron units as I wanted a screen and they seemed overpriced and seem to need extras, the Epever and Enerdrive units had exactly what I wanted in one bundle, a multi function screen and capability to expand the system later on, price for the Enerdrive 35 amp was okay but went out there for the 40 but the Epever was more reasonable, no brand tax and I have found it to be a very good unit all round, no need to buy extras either though I did spend $50 on a remote unit to stick inside as I get curious at times plus its lithium capable even though my wallet isn't.......
Do lots of research so you don't get ripped off on price or quality as there is lots of overpriced rubbish out there.............
Remember if you are charging at bulk rate for a long time you have a problem with your system, ideally it should be at bulk rate for a short time then into absorbtion or float , if your pumping in heap of amps for ages then you need more storage, my set up is usually fully charged by 0800 ish in the morning, I work on using about 25 to 35% of storage overnight with draw during the day fully covered by solar ..........
As a test to see if my set up was viable I ran my 3 way fridge off the van batteries, the solar kept the batteries in float and powered the fridge, surprisingly while I thought I would see max amps from panels, I didn't just enough to run fridge and keep battery happy.. Of course only an experiement run in middle of the day, you couldn't do it full time at all, batteries wouldn't make it to nightfall...
