#66 - Incompatible device encountered for parallel operation (e.g. old firmware/different settings) cleared on Solar Charger

Hi,

We are receiving this error every morning. Then clears itself automatically. Below is the general information about the setup. Has anyone encountered this before? What might be the solution?

Many thanks.


3 x 200 Ah lithium smart batteries

VE.Bus bms

Cerbo

Smart solar 100/30

Smart solar 100/20 48 V

Between the solar panels and the batteries we are using a Cyrix Li-Charge which is driven by the VE Bus BMS. The error pops up every morning when the sun comes up and is recovered within seconds automatically. Firmwares are up to date, settings are same, mppt's are in networked operation via Bluetooth and they are also connected to the Cerbo via VE.Direct cables.

Hi @Doruk Kocuk

Possibly caused by the wire/bluetooth mix. This normally wouldn't be recommended. Try disabling the BT network. It may not be working anyway if the wire kicks it off.

Hi @JohnC

Thanks for your answer. The system had been working in this setup for almost 2 years. This error came out of nowhere. However, the MPPT's have data connections to the Cerbo, Cerbo does not make them synchronized. It just gets data from them and shows it on the screen. I do not want to loose the ability to keep them always synchronised. It is strange that the error pops up each morning at sunrise and then clears itself shortly. Can that be related to a new firmware release?

Maybe a firmware thing, even the addition of the message you're seeing when it should have been showing before. But I'm guessing.

Nor do I understand the advantage you see in synchronizing the mppts, Even if it is working (and it may not be). This is usually for aligning the mppt charge states, and your BMS should be handling that anyway.
