problems with setup Quattros in Parallel

We have 2 quattros in parallel. with only Ac1 input used. There is manual switch on the boat that chooses either shore power or generator to this input. Ac2 in are not used. In Ve.Config we have an Instant " 2 signal Bms support " Temp1 and Aux1 are used for signals from the 123smartbms on the Lithium batteries. I setup the quattros in Ve.Bus configurator to be single phase with one Ac input. As this is sent to the quattro it erases the Instant which then gives an error that there are no Temp sensor connected. The chargers charge bulk at this setting. As I upload the Instant " 2 signal bms support " to the Quadro in Ve.Config the charge is switched to Float. The error ,no temp sensor, goes away. But in Ve.bus Configurator the setup is back to single phase with 2 Ac inputs.

Regards Nikolaj

Hi, can you try strip off the sensors and all external appliances connected then start again to program the system. Ensure they compatible to work in parallel on the firmwares on the units. https://www.victronenergy.nl/upload/documents/manual-VE.Bus-firmware-versions-explained-EN.pdf

Then make use of the VE Quick Bus software.
