Multiplus - 'Forcing' Inverter to come on

Have a very specific requirement for my Multiplus installation...

I have the AES enabled so the inverter is generally in Low Power mode and that is just as I want it.
However, occasionally and sometimes I want to have the inverter just come on and stay on regardless of AES settings and without the need to have a higher draw than AES specified to activate.

With my MP 12/3000/120 Installation on my Campervan I run an Induction Hob. I found in AES search mode that every few seconds the Hob would beep as the MP woke up to check for a load. To get round this, I fitted a fused spur (link to exact Spur fitted from Amazon here - https://amzn.to/35mGiqX), the idea being that when I wanted to use the Hob, I would just turn the Spur on.

As a side effect - and a very useful side effect which I want to replicate - I found that as soon as I turned the Spur on, the Inverter would immediately stay on, irrespective of the size of any AC load.

So now, whenever I want to make sure the Inverter in the Camper stays on for a reason, I can simply just flick the Spur switch on (don't need to turn the Hob on to do this).

So that is how I managed this on the MP 12/3000/120 but I want to be able to achieve the same result on my new 12/1600/70 Easyplus installation in my Motorhome, but I don't have a place - or normal need - for the same Spur as I linked to above.


Anyone know what in the Spur switch I linked to above would cause the MP to ignore the AES settings and force the inverter on? maybe the Neon light in it? Any suggestions for something similar (I would be happy with just a simple 20mm rocker switch with neon light to just flick on if that would do the same i.e. force Inverter on and ignore AES.
Or of course, is there another way (without going into VE Config each time) to force the Inverter to ignore the AES settings? Maybe an Assistant I can activate with an external switch? (I had a look at the assistants and found nothing of apparent use to do this)

MPPT 100/20 Load output AES - how should it work?

I'm trying to understand how the Load Output AES mode should work.

It's configured it as can be seen in the screenshot.

I thought it works like this:

If on condition ist met (V>13.50) the load is switched on for 32 minutes.

After 32 minutes the conditions are checked again and if the Off condition is met (V<13,35), the load output is being switched off, else it stays on.


But this is what it actually does:

The load output is being turned on after 2 minutes > 13.50V and turned off after two minutes <13.35V.

Is this how it should work?

If so, what exactly is the automatic energy selector timer for?

AES in Search Mode, how does it works ?

Hi !

I activated AES mode into my MultiPlus 48/3000/35-16, but i read in the manual about a search mode which can save more consumption.

I don't understand how it works... why there are 2 thresholds ? Why not only under a value set, it switch in AES Search mode and above in normal mode ?

I would like to keep on the multiplus during the night but only for a lamp, 7W, but it consume 20W all the night...

How to set it for this usage ? what are good thresholds ?

It seems not evident... : https://www.youtube.com/watch?v=5hLMoJSQesc, the flashing due to bad settings ?

Thank you for answers,

Regards

PS: sorry for my english, i'm french !

Multiplus 24/5000/120 settings: search mode, max charge current, input current limit

Hi,

I have the above Multiplus, BlueSolar MPPT 100/30, 2x200W/12V serial PVs, 2x200Ah/12V serial AGM batteries, Honda EU2200i generator and have the following questions about three settings:

1. If I have both the search mode and AES switched on, which is over-riding the other or can they work together?

1. For the 400Ah/24V battery set it doesn’t seem possible to set the maximum charge current as low as the generators continuous output 1800W/230V=7,8A. The lowest setting is 25% of something (percentage of what is still unclear? Maybe 100A x 25% = 25A?).

3. The input current limit can only be set to the following values:6,3A (1.4kVA at 230V),10A (2.3kVA at 230V),12A (2.8kVA at 230V),16A (3.7kVA at 230V),20A (4.6kVA at 230V), 25A (5.7kVA at 230V),30A (6.9kVA at 230V), 50A (11.5kVA at 230V). The question is how this setting affects the charging on different loads. It is clear that I should not have this setting to more than the generator’s continuous output power. But is it so, that 1) at no load the genset is charging with current of the setting (e.g. 6,3A), 2) when there is load up until the setting (6,3A), the load will be supplied 100% by the genset and the rest is used for charging and 3) when the limit setting (6,3A) is passed then the load will be covered by the genset AND the batteries and no charging will happen?


Thx.
