Hi. I have 2 x 200ah lithium batteries.
Use 2 x 100/50 Victron controllers.
Have 4 x 190 watt panels.
Only run 70 watt 12 volt fridge.

The system won’t hold charge.
I took batteries home & put them on charger via 240 volt power & the batteries are only at 25%.

What’s my issue?

The charger is always on BULK during the day - even though the batteries say 25%!!!!

Are panels wired in parallel? What is your PV line voltage?
If you have them wired in parallel they might not have enough voltage to charge a 24v battery.
What is your battery voltage? Are they in parallel?

Bulk means its trying to charge.

I recommend getting the Victron bluetooth adapter so you can see what is going into the charge controller.
