Hallo, habe gestern mein neues E-Auto bekommen und möchte es heute aufladen, jedoch kommt nach ca. 1 Minute zuerst der Fehler W-105 Überlast erkannt und dann W-105 Überlast aktiv. Fehler kommt bei 3- und 1-phasige Verwendung. In der Beschreibung vom EVCS finde ich nichts über den Fehler. Bitte um Tipps und Ratschläge. ---

Die genannten Einstellungen sind mit meinen gleich. So schaut es beim Start aus, nach einer Minute wird gestoppt: ![grafik](https://europe1.discourse-cdn.com/victron/original/2X/0/0e641e5f1d543677093192fcbc64b5d6275c8929.png) ![grafik](https://europe1.discourse-cdn.com/victron/original/2X/f/f8bfef3ff1e771f016da8b0d604cc69809542730.png) ![grafik](https://europe1.discourse-cdn.com/victron/original/2X/b/b787054da3a1320e0b0c13575bc6a10a99610326.png) ---

Ok seltsam, du hast „overload protection“ an der EVCS deaktiviert…. da sollte es nach meinem Verständnis die Funktion nicht geben dass abgeregelt wird. Ich kann das aktuelle Handbuch zur FW 2.x nicht finden. Das sollte doch so langsam mal verfügbar sein!? Evtl. hat es mit der Begrenzung auf 11kw zu tun…. Wenn der Fehler klar reproduzierbar ist würde ich mal „Input current Limit „ hochsetzen…. Testweise. ---

Bei meinem Sohn funktioniert die Original-Tesla-App nicht mit EVCS direkt seinen Tesla zu laden, Ladevorgang startet und wird dann abgebrochen. Direkt von HomeAssistant funktioniert das laden ohne Probleme. Ich werde die vorige Software auf EVCS laden, vielleicht funktioniert es dann. ---

Hat wer bitte einen Downloadlink für die EVCS Firmware vor 2.0? ---

I have same experience. Updated the software of NS charging station (type EV Charging Station 32A NS) to version v2.00 did not help. The charger randomly, usually in half a minute reports W-105. I set the car (BMW i4) to charge with only 10Amps. Charging @ about 6kW keeps the system switching off and on. Setting the car to charge with 7Amp reduces the power to 4.9kW. Then the chargers seems to be happy. I am of course less happy ☹ Any ideas that I can check?

Hello Two points: - Élément I have had a W-105 error on my EVCS. I connot start the charging. Problem in parameters ? - Élément Second point ,I have to start manually because he said Low SOC and don’t want to start. ---

Same problems here. Problems occurred after replacing former single Multiplus and installing complete new three phase Multiplus environment. The EVCS was already in use for a few months without problems. This morning I disabled the overload protection on the evcs and now the car keeps charging. ---

Thanks for your feedback. I’m only in mono phase environnment. It is a good idea to disabled the “_overload protection_” ? I tested to disabled like you and no alarm. Even if it’s disabled in the standard installation. Why to have this security ? If we have to desabled it. I don’t know the risk. ---

I believe that if your evcs is behind a good ‘Stromstoßschalter’ and your Victron system is correct configured there must be no problem. Maybe somebody else can tell us exactly the purpose of this overload protection. ---

Das bedeutet lediglich dass der Ladestrom der EVCS reduziert wird wenn der Multi in Überlast gehen sollte oder die Eingangsstrombegrenzung am Multi greift. ---

Hallo Hatte das selbe Problem Fehler W 105 und dann N307 Durch deaktivieren der Overload protection im EVCS, GX Device funktioniert es jetzt. ---

Is it a good solution to desable a protection ? [Next page](https://community.victronenergy.com/t/evcs-fehler-w-105-und-w-106/13705.md?page=2)
