Multiplus 3 phase Mains & Float LED's flashing

I have a 3 phase system, made up of 3 x Multiplus 48/3000/35. The system will not output or charge battery. The Mains and Float LEDs flash simultaneously.

I've checked the system configured the system using VE.Bus Config.

It is switched as a group. and each individual device shows no error when checked.

There is a mains 3 phase supply present at the inputs which has the correct phase rotation.

There is a 48 volt battery on the DC.

Wiring has been checked point to point, and this all rings through correctly.

What is the error being displayed? And how can it be rectified?

Thanks


Neil

@Battery_Boy

Do yourself a huge favour and get a GX device for the system.

Otherwise check the Victron toolkit.

Victron tool kit hasn't got this particular combination, however it appears to be a combination of the input being rejected and battery issue at best guess.

I agree a GX is the go to piece of kit, however in this particular application unnecessary, and it won't diagnose this issue anyway.

Thanks for your comments, it's good to hear someone's out there.

I'm experiencing the same- Mains On + Float lights flashing. I can't find a combination of this. I know my battery voltage is low but it won't accept power to pass-thru or charge the batteries.

Set them back to individual and use one to charge up.

Got the same problem here.

Mains and float flashing. It is not listed in the Toolkit app. Got all Victron cables, Ekrano GX and a 2 x 3phase system. The accumulators are at a 70% state of charge. No charging and just pass through. We got a working solar system on the system as well.

We had been over the system several times and no idea anymore.

@FunandSun

How else is the system programmed? Are all the phases programmed?

Hello Alexandra, thanks for taking a look at it.

Here ist the setup, pulled from the Multiplus directly.

The Multipluses never showed up in the Ekrano. I guess that is correct system behaviour. img-6204.jpeg

Yes the three phase config is done. But in its base form virtual switch is active as default.

So if each unit is not programmed in nay way then it is ignoring AC.

Thanks Alexandra, I think I got now what you mean. Now as you write this, I remember an instructional video from South Africa, (in which the sound was awful), I think they mentioned that as well.

My task tomorrow.
