Question Deep Discharging - How to and how often?

After thinking about this for a while I wonder if the folks at EG4 might be willing to write up some TSB's regarding this subject?

Maybe they could detail the specifics for each inverter and each type of battery?

If this needs to be done, I am more than willing to add it to my maintenance schedule, but I really need to know what the best practices are to achieve best performance and longevity for my batteries and my inverter.

I would hate to do something wrong based on some random interweb video and then lose my warranty on the equipment or cause some long-term damage.

Yes, that is an interesting question. I've never heard of any benefit of deep discharging. My normal practice is never below 20% and monthly top balance charging with voltage.

I didn't notice an EG4 response and am hoping @eg4eric could direct us to a document that outlines the specific procedure to discharge. On another thread I had seen a mention of the process including changing the battery type to lead-acid as "the only way" (during the process).

Could not find any specific documentation on steps to set in the Monitoring center (for either 1 or 2 batteries to properly balance - at the low end) In my case I have a 12kPv with 2 Wallmount batteries.

It was mentioned here .. but not outlined graphically to increase my confidence of doing it properly.

I've attached a few helpful links that explain this in more detail. It’s recommended to maintain an 80% Depth of Discharge (DoD), regularly discharging the batteries down to 20%. This helps prevent the battery cells from becoming imbalanced. If the batteries are not discharged regularly, cell imbalance can occur. The Recalibration Guide provides instructions on how to top balance the battery if needed.
