ESS charging

screenshot-20230321-124350-chrome.jpg

Hi I have an ESS system in operation as above, my issue is why am I exporting over 1kw and only charging at 64w?


I have the 48v multiplus with 200ah of Gel batteries.

It is set to optimised with battery life and self consumption.

Thanks in advance

Dave

...what's the target voltage in DVCC settings for your pack and the settings for the batteries in ESS assistant...do these match your batteries?...with SoC already quite high and voltage of 58.26V in cold weather, the system may be close to fully charged already.

May be charge efficiency value is not correct - every battery have different value - try 0.85

Hi, the DVCC option in the menu is switched off, with a message saying read manual before adjusting.
