MPPT charges then drops to 0W – help?

Q&A and troubleshooting

Hi everyone,
I’m exploring solutions for my Victron setup and could use some community insight.

Here’s what I’m observing:
:small_blue_diamond: My MPPT charger seems to charge normally, but after a short time the power drops to zero.
:small_blue_diamond: I’ve checked the wiring and settings, and everything appears connected correctly.
:small_blue_diamond: I’m using a VE.Direct MPPT with a Cerbo GX and lithium batteries (please let me know if more details are needed).

Has anyone seen this behavior before, or can suggest what settings or tests I should try next? Thanks in advance! :blush:

If all your connections are good (not getting hot) and well sized we would check programming.

Does the battery actually need a charge?
Is the mppt raising the battery voltage to the target progrmmed?

To help we need to compare your settings with what the battery recommends and if the mppt is actually doing what it is programmed to do.
