Ii have a MultiPlus-II with two AC outputs, i wantvto switch on and off AC output 2 with a daily timer, regardless of batter soc or anything else power related. Is there a way of doing this in remote console or assistant settings in the MP2?
I want to avoid node red as i just cant get my head around it. But if node red is the only way, then can someone please illustrate the flow chart?
Hi. Multi Assistants can switch ACOut2.
But they don’t know absolute time. You could tell them the schedule via the GX, using the Generator Start function. With a signal wire pair run between a GX relay and an Aux relay in the Multi.
Easy to change your set times from Remote Console, but a possible downside is that VRM/RC may report it as genset runtime. Hopefully they’ll fix that one fine day.

Other way is to buy a smart switch that you can program and drive a contactor to disconnect loads.
Basically i have assigned the assistant to turn on AC2 when batteries reach 95%soc and to turn off AC2 when soc drops below 95%soc, then i also set gen start time (quiet hours) to turn on AC2 (via aux1) at 1am and off at 4am, also i have set generator to start when batteries fall below 15%soc.
So far i can omly get AC2 to turn on when soc is below 15%, all orher settings cause no reactions to AC 2, leaving it switched off. So why is my assistant settings not responding, and also my quiet hours settings not responding ?
What’s this all about? If this is in the GX, remember that you’re not starting a gen, you’re switching Aux1 in the Multi. If you want to actually run a genset, you could run Assistants to switch K1 (or whatever you have). Different animal, remove it if that’s what you’ve done.
With multiple conditions for switching ACOut2 you have to be careful of the order in which you place the Assistants. Visualise a set of conditions and read through them, the latest have priority, and what comes out at the end is what you’ll get.
If you want AND conditions, start with ACOut2 ON, and switch OFF when the condition ISN’T met.
For OR conditions, start with ACOut2 OFF, and switch ON when the condition IS met.
I get what your saying, and i think i mixed too many assistants with and and or together.
Basically i have reconfigured the assistants down to 3 now. When soc higher than 75% (it will be 95% once i know its working) turn on AC2 out.
When aux 1 is closed for 10 seconds, turn on AC2, when aux 1 is open for 10 seconds turn off AC2, and then i configured the conditions in the gx generator settings to trigger aux1.
Will this work?
Also is programmable relay 2 , set relay to off necessary, or will AC out 2 turn off once aux1 is deactivated again, when gx relay opens?
My problem is that I don’t actually know what you’re trying to do, so just guessing. Maybe this sequence (an OR condition)…
Switch OFF ACOut2 if Aux1 is open for 10 sec.
Switch ON ACOut2 if SOC is >75%
Switch ON ACOut2 if Aux1 is closed for 10 sec.
Try to visualize your system reading this over’n’over constantly. Does the end state fit?
I don’t do this everyday either, so can stuff up. But you’re asking the right questions and having a go. Love it.
Im trying to use AC out 2 to turn a contactor on and off to isolate my grid power from the inverter while i have good soc, but when batteries become full, i also want to tap back onto the grid to export excess to keep my meter clocking up, as i get paid for generation.
The idea of using ac2 to switch a 230v coil contactor is because ac ignore on the inverter does not do what i want it to if i add generator backup into the mix.
I want to be completely off grid (not grid tied) while in ess mode.
