EM540 or VM-3P75CT speed regulation in ESS config

Q&A and troubleshooting

I am considering which energy meter to install: EM540 or VM-3P75CT? The setup includes an MP2 5000, a 16 kWh DIY battery, and an external Cerbo GX. Are there differences in the speed of regulation behavior in an ESS configuration? In other words, does one of the energy meters reach zero balance faster?

Best regards, Jo

Hi they are both 100ms so both fast, vm uses ct clamps, em540 is direct/shunt, vm is 80A, em is 65A

Im using the em 540 and happy with it
