Good afternoon! My solar station worked for two years without much trouble, but last week the opportunity to transfer electricity back to the grid disappeared. The station just disconnected in the middle of the day from the network, and still I can’t back. I have 3-phase Multiplus -II 48/5000 and Smart lithium 320Ah batteries. Now the station works from the sun by day and from the batteries by night. The Remote console does not show errors, only Active AC input shows Disconected, although all voltages and frequencies are Ok. Perhaps someone can help in this situation. It seems that I have already tried everything. All firmware is latest. Thanks in advance. ![Console](https://europe1.discourse-cdn.com/victron/original/2X/c/ced15ed12bdc4f6de2e341bc6fda84ced737646f.png) ![Alarm status](https://europe1.discourse-cdn.com/victron/original/2X/3/37e926af80a1b4e718db2db4008f16956eece6d4.png) ![Ess](https://europe1.discourse-cdn.com/victron/original/2X/3/31e09b6f4bea6393cddbc721fa982efdf53d71f4.png) ![Portal](https://europe1.discourse-cdn.com/victron/original/2X/3/3fd87e275538d4dd8975ec740d88ec321956c280.png) ![System setup](https://europe1.discourse-cdn.com/victron/original/2X/0/06db35faf24538d0e6d72424fa01e82f208e2852.png) ![Bms](https://europe1.discourse-cdn.com/victron/original/2X/0/0268183fc430c25a4b60944ea15d3e46dec35e7c.png) ![Devices](https://europe1.discourse-cdn.com/victron/original/2X/7/715923b557ec7dbf692142068f24bacd34729546.png) ![Multiplus](https://europe1.discourse-cdn.com/victron/original/2X/6/6864f4ff6f867ed98b9ca8ed054b7e290dbfbf6c.png) Active AC Input is disconnected, always.

@JanS I am not familiar with the grid code tolerances. But I would start evaluate there. Is the voltage in the range set by the code? Do the inverters show input voltage in the GX? Devices - Multiplus… ---

Oh boy. The mystery deepens. Is your grid meter ok.and communication working ok? If you use the main incoming breaker and switch on and off does anything change? ---

Out of curiosity what grid meter are you using and how’s it connected? Just I’m having a similar issue and thinking it’s my grid meter. ---

This is likely definitely part of the headache. ---

Thank you to everyone who got involved in solving this problem. The meter is ET340 and working. A solution was found, this was not a problem for Victron. The electricity supplier was to blame: instead of three phases, only two were supplied, but three wires each. There was a short circuit between the two phases. There was 230V between the zero wire and the phases, and 0V between the phases. Victron does not understand such a situation and does not show any error. Perhaps it is necessary to install an interphase indicator, if there are any at all. Maybe Victron has the option to see the correspondence of the phases to the sequence, the rotation but it sees but doesn’t see that the two phases are the same? ---

> [@JanS](#): > > and 0V between the phases. but how could your gridmeter then report 230V for each phase “just fine”? It should at least have reported 400 / 0V for two of them. Or are you running your gridmeter with the L1,L2,L3 voltage sensing (and N) connected to the AC OUT of the multiplus, rather than the actual AC-IN lines? ---

The meter is standard ET340, connected immediately behind the inlet fuse. Apparently, the counts do not measure the interphase voltage, but only between phase and zero. I found ET340 in the instruction that it is possible to read not only phase-zero L1-N, but also phase-phase L1-L2 etc.t Maybe it should be included in the Victron settings to see this value? ---
