I appreciate the info, but I don't love how the "download" is just a link to your personal website where you promote your wares for sale. This site would be awful if more companies were adding links and generating "content" this way.
This helpful 'resource' which promises to present info about how to extend the life of your batteries does so by telling you how the TaoBMS system's features can do the job. This kind of seems like an undercover advertisement.
SOC corresponds to the average State Of Charge of the cells. It has an important impact for calendar ageing.
For example cycling the battery regularly between 60% and 100% soc would roughly correspond to an average soc of 80 %. That's why it is better to cycle the battery through its full capacity (within reason!) to lower the average soc when the installation is in full use (absolutely avoid float).
When the installation is in "storage mode" for a long time with low power usage (example: only a fridge and some safety equipment / lighting) it is better to cycle between for example 30% and 60% soc and do a full charge every 30 to 45 days (that's where an intelligent BMS can help ;-), but lowering the voltage of the solar regulator (13.2v?) will also avoid keeping the battery full all the time - it will just do micro charges every day and I do not know if that is good or not? )
