What is causing DC ripple with my Quattro?

Running a system powering a number of cabins.. Setup consists of 16kva generator, 10kva Quattro and 400ah of battery storage. Loads range from 7kw to 16kw during the week and 2kw to 6kw on the weekend. I have the system set up to fire up the generator on loads greater than 4.8kw so during the week the generator runs continuously with the batteries/inverter operating in assist mode to support demand spikes over 12kw. On weekends demand is served by the generator or batteries depending on load/soc. During the week the batteries are almost consistently at 100% soc and at weekends they vary from 50% to 85%. My question is why do I see lots of dc ripple alarms during the week but not at weekends. I realise the loads are lower at the weekend but so is the soc. I have another system running similar loads but without any dc ripple alarms.

I’ve read the article and checked all connections etc....can’t find anything amiss. How common is this?
