Hi @Bill Wilson,

See here for the 6 causes of 'pass-thru' and what can be done - https://www.victronenergy.com/media/pg/Energy_Storage_System/en/faq.html#UUID-169dbd85-4b6f-814b-33c2-9fa77a6973d2_section-idm4628123204859232885885561444

I am pushing to make this clearer in the user interface itself.

Hi Stewart.

The system was working OK switching on charge at 80% battery and off at 95% but now the batteries are just discharging slowly and are currently at 69%

Have you got a Maximum Charge Current Limit set in the DVCC menu of the GX device?

Have a look;
