> Is losing your grid meter without it coinciding with a grid outage a common occurrence? It happens all the time, especially when charging. Multiple times per cycle. I have been posting on this topic, I sort of gave up. I now bought a EM24. One of these day I will implement it. I hope the issue will be gone then. > [@External grid meter dissappears frequently while charging causing Passthru mode](https://community.victronenergy.com/t/external-grid-meter-dissappears-frequently-while-charging-causing-passthru-mode/15981): > > During charging my 3-phase MPII 5000 system switches frequently to Passthru mode. There seems to be a relation between SoC and occurances. This starts to happen more often when the SoC increases. It can happen as often as 30 times per charging cycle. When debugging this issue I used Node-RED for alarming me. I found that it happens when the connection with my external Grid Meter is lost. This is a CG-EM340. The grid meter works fine otherwise. So I made an alarm in Node-RED for a frozen power … > [@Em24 disappears in device list and system goes in passthru mode](https://community.victronenergy.com/t/em24-disappears-in-device-list-and-system-goes-in-passthru-mode/15486/2): > > Hi, I have a very similar problem with my CG EM340. Except that my grid meter returns within a few seconds and my meter is connect via USB-modbus. Could you take a look and see if you find an error message in “Console | Services | Modbus/TCP”? > [@Cerbo keeps losing connection with CG EM340 Grid Meter](https://community.victronenergy.com/t/cerbo-keeps-losing-connection-with-cg-em340-grid-meter/21776): > > My systems suffers from losing connection with EM340 intermittently, going into passthru mode multiple times per hour. It happens mostly during charging (98% of the time) my 48kWh battery. Never when discharging. It started a few months ago (probably before v3.50?) The behavior is identical on the latest official release and the latest beta (3.60~24). The meter is connected via an official Victron USB-485-converter.

Without a grid meter and with AC-loads or PV on AC-inut, this means riding in the dark. You can´t do peak shaving if you don´t know what is happening between the grid and AC-input, can you? ![afbeelding](https://europe1.discourse-cdn.com/victron/original/3X/2/6/2663c82e4e9a2be844a30b21b8351b20c8b942ca.png) --- _[View the full topic](https://community.victronenergy.com/t/venus-os-v3-70-61-available-for-public-testing/45708)._
