Hi Leute, ich habe ein kleines Problem mit dem Multi Rs Solar 48/6000, vielleicht ist es auch keines. Wenn der 220-Volt-Invertereingang in der AC-Eingangsteuerung bedingt abgeschaltet wird, kann er, nach einer Batterieabschaltung (Undervoltage Protection etwa) nicht mehr selbst starten. Er versucht zwar den Restart, bricht aber ab, weil kein AC‑Eingang da ist. Das wiederholt sich dann konstant. Hat das selbst schon jemand erlebt und gibt es eine nützliche Lösung? Danke für hilfreiche Tipps.
Kann es selbst nicht testen, habe es aber mal weitergeleitet.
What was the condition that you programmed to disable the AC input?
Can you reverse that to re-enable it?
I have also asked if it’s possible to do a factory reset (before the conditional ac logic is enabled)
When enough sun, I don’t need AC Input, so it is disabled, even so AC Input based on Load is activated. Yes, after shutdown, you have to connect via Bluetooth with Victron Connect App, and switch off “Conditional AC Input connection”, then the Inverter will restart. But it does not recognise the Batteries, it needs to be synchronised in the App as well. Unfortunately, it can only sync with 100% for the Multi RS Solar, while in the BMV-712 it can manually sync with any value. Anyway, I just recognised it when worked on the batteries packs and disconnect them via BMS, and the second time, the value for undervoltage protection was not set up correctly on the new pack.
Oh wait, the problem is not the AC Input only, if no Batteries can be detected (even they are connected), it can’t start with disconnected AC. 
Which batteries are these?
Have you got a copy of all of your settings you could post here?
Self-made 3 x 340 AH 17S with JK BMS. They are not connected via CAN. Could not figure it out yet. Maybe, this is the reason the Inverter don’t see it.
" ac input connect based on load" set this to OFF, that’s what I have (multi RS 6000 with jk bms diy batteries).
why not use the ess function ? its much nicer

I will try, but this function works well for me.
I cannot see how to implement it other than switching charging on/off over AC Input.?
I plan to go off grid , AC Input is not available any more then.
so ? whats the issues ?
When the AC Input is switched on, the Inverter use power from the grid. Since yesterday, I have now ~54 KWh batteries storage, I wish to use it exclusively. I have a small single household, it should be possible.
ESS has no benefit for me because it is a house installation. It makes sense in a camper van when plugged in at a socket.
well it would simply use nothing from grid unless the battery is low
That’s right, in actual setting, as shown in the picture, it uses only batteries. So, your picture implies an external control, which I don’t have yet. What is your external control?
Start- up sequence:
1: power up battery
-
power up Multi RS 6000
-
power up AC-in from grid
-
switch On mppt DC switch on Multi RS
Second, read the manual, you find your answer there about running the RS without grid… Actually the RS is designed to function without grid (or PC) literally to have power in the field, (that’s why there is an display on the RS)
Yes, I installed the Inverter in 2022 and it runs well since. The Problem in my first post I discovered just earlier this year. It seems nobody else experienced it, so I have to figure out how to cope with it. Anyway, it seems there is no fault, if AC-In is powered off and the batteries shuts down, of course the Inverter shuts off too and can’t restart because of missing power.
Problem solved.
