Is there a way to activate the AES of my new Victron Multiplus 48 70/100 from the connection with the Cerbo GX or do I need a special cable connected to the multplus yes or yes.

Hi guys,

When I configure my new Multiplus 12/1600/70 with AES Search Mode enabled to start saving below 12W and stop saving above 44W - the lowest permitted values by Victron Connect (see the screenshot below), the AES actually never starts, despite Victron Connect showing consumption under 10W. When I increase start to about 22W it will properly switch to AES mode, but I would like to go as low as possible. There is nothing connected to AC OUT at this moment.

What could be the explanation for this?

thanks,

The spec sheet says 20W. On the unit I received today I measure 29W at 13V and 32W at 14V. This is a critical parameter for me. 50% higher than advertised is absolutely unacceptable. Any insights out there? Do I have a defective unit?

Updates:

My induction cooktop in standby mode (i.e. plugged in) disables AES even though it's a negligible load of a couple of Watts. Likely because of its input power supply stage - but still - AES can be and should be engineered to work properly under this conditions.

My AC current limit is off by a factor of 2. When I set it to 12 Amps it's activates at 24A. When I sent it to 6.3A it activates at 'about' 12A but it's still a bit all over the road.... Victron quality!? Wonder what I will find next......

All in all this is a significant disappointment.

I got an SmartSolar 75/15 and a foldable solar panel only connected sometimes. The SmarSolar load output is configured with AES and connected to my Fridge S+ signal. So if I have excess Power it will switch on the load and the fridge will use 12V instead of Gas.

My problem is the AES logic in the SmartSolar also switches on if the condition are met due to other reason (230V battery charger or B2B charger from car generator) but no solar power is present.

Is it possible to have an additional AES settings for minimal Solar power for AES to switch on, additional to the existing config. This should also solve the issue that the AES might switch on late in the evening when there is not enough power for the fridge present to prevent drawing too much from the battery.

Thanks,

Hi everyone,

I am using ESS assistant to store excess solar power into a battery (2.4kWh). If there is not enough solar yield, the batteries will deplete to the set minimum SoC (25%), and ESS stops feeding energy from the battery. That is all okay, my problem is that whatever minimum SoC I set, if the current SoC reaches 5% below the minimum SoC, the Multiplus starts charging the battery from the grid.

ANd that happens quite often in every ~7 hours. I would like to disable that feature in Multiplus, and let the battery goes even empty, until there is enough solar power to charge.

The AC inverter of the solar panel is connected to the AC-IN of the Multiplus, so I don't think I can disable charging completely, as that would disable the charge when there is extra solar energy.

I understand the intention that the multiplus charges the battery if it goes "too empty" but somehow Multiplus consumes that 5% too quickly.

I was also experimenting enable AES, to minimize consumption from battery, as there is no load currently on the AC-OUT of the multiplus, but whatever settings I set, it never goes into AES (I guess it's a bug, as I can see many complains on that.)

Any idea how I can set an other minimum SoC for charging from grid?

Thanks in advance

I bought a Multiplus 2 12/3000 to replace my 12/1600 but AES won't start with settings below 116W. Can anyone confirm this for the Multiplus 2 line or is there a fault in a single unit?

I have set up a 2 phase system with 2 Quattros, only to find that the aes does not work. Looking a little deeper I find that AES settings will be ignored when the device is part of a VE.Bus system.

How can I get AES to work while being a part of a VE.Bus system as the amount of energy consumed is so great being 120 watts per inverter thats a total of 240 watts while they are doing nothing thats 5760 watts a day that I was unaware of due to the misleading information on the technical specifications data sheet which states 55 watts which in my case should be 110 watts.

At the moment the stand by draw is so great and so out of misleading specifications that it is not really acceptable. I also do not see anything on the data sheet that AES will not work as part of VE.Bus system which is needed for multi phase or parallel set up. I also expected to be able to use this function with my 2 phase set up.

I think that my MultiPlus II (48/3000/35) doesn't enter AES (neither if configured for search mode or modified sine wave), even if there aren't any loads connected to the output leads.

Is there an indication somewhere about the currently active AES mode? What I'm trying to do is to find it out based on input current on the shunt or measured with a dc clamp, and the output frequency/vrms in search mode.

This is what the Cerbo shows with all AC leads disconnected (and no dc consumers other than the Cerbo, the BMV and the Ve.BUS BMS).

And these are the values that I would expect, from the datasheet:

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)

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?

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 !

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.
