Blue Smart IP22 Charger | Current jumping up and down

Hi there,

I have been having an issue with this charger for some time now where it starts perfectly fine for the first 10-15 minutes (please see screenshot 01 attached) and then starts jumping up and down (Please see recording attached). I have placed it in 'night mode' ( Please see screenshot 02 attached) where it seems to give me a steady 15A without dropping but naturally I'm keen to get as close to the full 30A that the charger is capable of giving.

I have the Victron MPPT and Orion and between the both I rarely had need of the IP22 but I'm nearly certain this 'jumping of current was not happening for the first few months of installation.

Worth noting, though the charger comes with a blade fuse of it's own, I have installed a breaker on the positive line to my Lynx Distributor, not sure if this could be causing issue?

Any insights would be amazing - thanks!

Hi @Jbrop

What type of battery do you have? Does it perhaps have an internal BMS or do you have an external BMS?

Kind regards,
