EM540 setup on monophase system

Q&A and troubleshooting

Hi,

I want to set EM450 meter on a monophase system. According to the manual, the meter can be set using two phase, one for measure energy and another for measure a PV inverter, on ACin or ACout. So, we have L1-N as grid and L2-N as PV-inverter.

I want to use the third phase, L3 to measure another device, a generator, another PV-inverter or external charger.

How can be done?

For the moment, I’m in this situation, L3 is available but cannot use it via GX setup…

Thanks

You can’t also use L3, its not supported as far as i know

Maybe could be implemented on future firmware… as a feature request

Something like: Use L3 > role > grid/pv inverter/ generator/ charger …

Or instead use multiphase, but with option to set each phase specific role.

Seems like it’s a common wish the ability to set each phase with specific role and device associated ( Victron ET340 (Carlo Gavazzi) Energy Meter )
