Hi
On yacht with a Cerbo GX, 2 ET112 and a smart shunt
One of the Et 112 is used for monitoring the grid (shore power)
On the VRM was configured an alarm in Settings/ Alarm rules/ Grid meter / Grid L1 power low alarm at 5W clear 6W and high at 2250 W clear 2200W.
It was working from the installation at 10/2/2021 Until 07-10-2021 at every disconnection of the power had an alarm
Grid meter - SHORE POWER [31] | Alarm rule | Grid L1 - Power |
from then on i had 2 more disconnections the last one for more than 16 hours with out alarm
I test it on an other installation and after the disconnection the value on the devise was the last known.
