Dokio 300w folding panels puzzled!

300w Dokia folding panels
Supplied controller

Hooked up in full sun shows 13.1 volts and around 8 amps output. Sounds good. But,

The batteries, 3 new flooded interstates, do not seem to be receiving any current.

Zero increase in battery % , nor any change in “current” in Victron app.

All connections seem solid

I sincerely hope the above description is adequate.

Have read the controller manual.

If I disconnect the alligator clips, the current value of 0.75 does not change on Victron app.

Best

Do you have the solar negative lead running through the battery monitor shunt?

[zoso1971]

Is your negative battery clip directly on the battery negative post? If so move it to the other side of the shunt or a trailer ground.

No

I was connected to to battery terminals

If POS gies to battery terminal, EXACTLY where on shunt does NEG go on shunt?

ASSUME “Load and Charger”

Thank you
