VRM Advanced - Cerbo GX system uptime

Would it be possible to add to VRM the ability to publish the uptime of a Cerbo GX system uptime? Also publish Cerbo GX restart into the event log?


I am troubleshooting an intermittent problem with my Cerbo GX WiFi where it occasionally stops and have the "restart GX after X" feature enabled. I would like to be able to more easily monitor when it restarts.

Thanks

Grafana daily totals (Grid Tied Inverter)

Hi all

In process of setting up a Grafana dashboard to monitor my ESS system but can't seem to work out how to display the total yield (daily, month so far) of my grid tied PV inverter.

I have a ET112 meter on my solar and displaying current generation is working fine

Tried different query options on several fields but can't see to nail it

Anyone managed to who wouldn't mind sharing the secret?

Thanks

URGENT: Battling with USB on MultiPlus-II GX with Powered Hubs

Due to the non-availability of MultiPlus II, we have been using MultiPlus-II 5kVA GX and are having serious problems with the USB port for multiple USB / VE.Direct devices.

All installations I am referring to now have maximum 2 x MPPT (1 x USB to VE.Direct) and 1 x Energy Meter (1 x USB to RS485).

We are using high quality 30 USD D-Link DUB-H7 hubs with 12V power from an Orion 48-12 DC DC Converter. On a near daily basis, we are having to reboot the GX device because one of the two USB devices disappears.

It has been suggested to me by another installer that this is a nanopi problem. We would appreciate some assistance from Victron in this respect. PS. We did try USB powered hubs and we had the same issue.

We now have 5 installations with this issue and around 3 more going in each week. We have to find a solution.

Two separate ESS 15kVA and 500VA

Hi,

I currently have 3x MP ii in parallel, running well in ESS configuration no issues and very happy I chose Victron except after a year I realised the efficiency is not as expected and trying to improve.

I’ve seen multiple posts and read manuals but can’t satisfy my knowledge on what would be the best approach to this particular scenario.

For low demand times I want to implement a small 500VA multiplus and turn off the bigger inverters, connected to the same 40kWh battery

One approach I know would work would be to double all components: Modbus meter, smart shunt, GX device, this wouldn’t be worth the effort

What I’m hoping is to be able to tap in the Cerbo somehow to share the existing data available for the small inverter to keep the ESS grid set point at 0W.

I’ll have to use only the AC IN terminals on both inverter systems for this set up

It’s almost like I would need a transfer switch on the VE bus.

Any suggestions much appreciated

Thanks George

FeatureRequest: EasySolar2 GX & MP2 GX 2x16 Display Customisation - Show Tanks & Temperature Sensors On Built-In 2x16 Screen (For Offline Use)

Hey Everyone,

I dont think what we need can be done, so asking on here to double check and maybe get some upvotes in the hope Victron add to their dev list.

Open to suggestions for possible DIY modifications, if that is possible, but would prefer to avoid modifications to Victron GX products under warranty.


Snip below is from ES2GX manual - GX Device Display - lists no possible options for customisation

[image]

I have 2 client systems, both are mobile systems in RV's utilising a EasySolar2 GX 48/3000 at their heart. Both Systems have a USB Hub with BT dongle for Ruuvi's and a GX Tank 140, which is used to connect 24v 4-20ma Tank senders.


The problem comes from them being mobile installations, as the 4G signal can be patchy and is occassionally unavailable for their chosen location.

When they are offline, they have no way to access the Tank information without resorting to remote console on LAN, which is not really suitable for all types of User.


Connecting to a wifi network that doesnt have internet, to get to the remote console on LAN, to then be able to look at the tanks seems a bit crazy, as the GX device has an inbuilt display to provide the essential information at a glance.

Primary use of this display, IMO, would be for when there is no internet, so would be handy to be able to see all of the relevant information to the system on it, not just a set of defaults.

Whilst the Tank's not being displayed is the primary complaint, it would be nice to be able to display the Ruuvi tag information on this screen also, but tank information is most important.


As the GX device is integrated and internally connected to the multi & MPPT I cannot even swap it out for a Cerbo & GX Touch, so am a bit stumped on how to proceed.

At present the only option I have to resolve both customers complaints is to purchase a tablet/ipad, mount locally in Kiosk mode, then use this to display the remote console.

This is only marginally better than using remote console on a phone, if this is how it has to be done then I would have to use GuiMods to customise the remote console to show the info on the home screen.


Any suggestions on how else this could be done would be very much appreciated, cheap tablets are almost always trouble!

If these features can be added to Venus OS then they would be useful to all systems containting a ES2GX, MP2GX or MaxiGX.

Cheers,

Rob

Low amp soft starter recommendations?

Hello!

Like many others, I have a small fridge which is creating such a surge when the compressor kicks in that it hits the inverter (Phoenix 12/800) too hard.

The solution would be a soft-start module between the fridge and inverter. I am only finding these at around 16A current limitation. This would mean a peak wattage limit (~3500W) above what the fridge is creating anyway, and still higher than the peak the inverter can handle.

Is my reasoning correct?

Or, would a common 16A soft-start module do the trick anyway?

Or, can you recommend any low amp (by my maths, less than 6A) soft-start modules to keep the peak below inverter peak?

Thanks in advance!

Phoenix 12|800 Inverter - surge / peak / spike protection or smoothing for refrigerator?

Hello!

I have a setup running a Phoenix 12/800. It is all running very nicely with one issue:

We have a very small (43L) Ikea fridge/freezer which uses only about 30W continuous power when on. The problem is, when it cycles to ON (ie compressor kicks in), it demands such a peak that the inverter jumps into the red zone of the meter (bluetooth app) for about half a second before coming way back down to 30W. In this time the inverter is clearly struggling and the lights dim etc! While plugged in, the fridge cycles on/off once every 5-10 minutes. Naturally we have now disconnected the fridge.

  • Is there some utility to 'absorb' / 'smooth' this peak as not to stress the inverter so much? Will a surge protector do this, or just turn off?
  • Are there fridges with smoother / softer peaks, or is this a universal issue?

FYI: Battery bank is 3x 280Ah 12V, with 35mm2 wire connecting. Wire from battery bank to inverter is 25mm2, which i believe is the largest you can fit into the connectors on the inverter housing.

Update: some have recommended soft start modules, if anyone can recommend a specific unit I would be grateful!

Many thanks for any input!

Smartsolar not showing up in venus or vrm anymore

Hi!
I have the Venus Pi, Smart Shunt 500 and the Smartsolar MPPT 100/30. All updated to the latest firmware and connected with the Ve. Connect USB cable.

When I plugged the solar into the Venus I could see it. Later on it has disappered. I think it happened after reBoot or firmware update. The MPPT has not the solarpanels connected yet, but is connected in the battery side.

The Smart Shunt is working correct

Any clue?

PV fluctuation

Good day,

I am not an installer or dealer but have a question regarding my multiPlus II.

We have recently changed from AGM (4 12v x 220Ah) to lithium (1 x 48V 100ah) battery and since then the PV fluctuates. The installer changed the settings on the MPPT and VRM portal.

my current setup:

1 x Victron MultiPlus-II 48/5000

12 x Canadian 405w

1 x Vicrton SmartSolar MPPT 250/85-Tr

1 x Victron Color Control GX - set to keep batteries charged

below is a snippet of the PV Yield for the last hour.

[image]

[image]

When the mains are disconnected (loss of mains (load shedding here in SA)) the PV generates whatever the load is.

Why is the PV generating less when mains are active since changing to lithium?

Any assistance/advise will be highly appreciated as I am getting no joy from the installer or dealer.

regards.

Victron OS - new DC-meter feature

Hi!
I do not yet understand the new DC meter feature highlighted in the changelog of the new Vitron OS versions: There is a 115A alternator, a Silentwind generator and a MPPT100/50 (500Wp solar panels) in my system as charging sources for my 330Ah lithium (cruising sailboat setup).

All negatives of the charging sources are connected to a central minus distribution busbar and this minus busbar is connected to the shunt of aSmart BMV712 which then is connected to a 330Ah smart lithium from Victron.

So far I am getting fine readings on the VRM screen from the MPPT100/50 which is connected to the Raspi4 running Venus V2.80-16-large21, but no additional widgets for additional charging sources or something like that.

So when switching the BMV712 to DC meter mode: What shall happen when getting charging amps from the wind generator and/or alternator? Maybe I am completely misunderstanding the whole topic about the new DC meter feature?

Thanks upfront for your support!

IP65 12/25 2021 inrush current and save fuse size?

Based on a ‘zeilersforum’ topic I found this question discussed: “Blue Smart IP22 charger trips automatic fuse” in this community.

Summary: a IP22 12/30 will trip a 6A and 10A fuse and not a 16A. So, you may need an inrush limiter as proposed by Victron.

In the same discussion Victron added that this phenomina has been discussed while preparing the IP65 design.

Old harbours may be fused at 6A or 10A rather than 16A. The shore fuse may not be accessable after it trips (a reset will do, if accessable).

1:-is the IP65 12/25A model year 2021 adapted in a way to limit the inrush current to 5A or such that a 6A fuse will not trip?

2:-to which save fuse size have the IP65 improvements result in: are 6A and 10A tested?

3:-if not, is Victron willing to test this (or these) charger(s) in order to document needed fuse level and inrush limiter recommendation?

4:-is there a Victron approved hardware interface or schematic with component list available for save use at 6A fuses (a 5A inrush limiter)?

5:-neither manuals are prescribing an “aansluitwaarde” (current supply level) and do not warn for low level harbour fuses. The charger will only take 1.5A average so this inrush is very unexpected. Will you update the manual or supply an addendum on the product tab of the website?


We have a seagoing trailer sailer located in the Netherlands and are planning sailing from remote locations next year, where neither 16A nor 24/7 harbour master may be obvious. The IP65 12/25 is the main charging source for the lfp battery.


Please add the question numbers as a reference to your answers. Thank you.

Possible Bug in VE.Can MPPT - High Battery Voltage Alarm

I had many High Battery Voltage Alarms after install today of the first 250/100 VE.Can

Good news is we now have another 3,920w Solar array working on the boat!

But the alarms were triggered by the MPPT relay output set at 28.00v and off at 27.90v. (I was hoping to use it to turn on a battery fan during charging)

Every time the MPPT hit 28v the alarm was triggered and cleared below 27.9v, but I didn't expect an alarm warning from setting the relay. (Simple FLA battery bank 28.90v Abs, so alarms were below Abs voltage)

Turning off the relay didn't stop the alarms, but setting the Voltage trigger points of the relay higher have at least stopped alarms for now.

Setting a disable alarm rule in VRM also didn't stop the alarms.

Smartsolar MPPT VE.Can 250/100 v3.04

CCGX V2.63

These Settings stopped the alarms (Setting the relay to be triggered at a higher voltage than battery voltage):

Scheduled charging without ESS

Hi, I just switched on my installation of 2 Multiplus 3000s and a Venus GX and am now looking at scheduling power draw from the grid. I'm in the US and have a grid tied SMA inverter in parallel with the Multiplus. Since I can't set a grid code here I can't use ESS.

I'm able to handle turning on and off AC input with modbus but couldn't find a way to disable charging without using one of the relays which I'd prefer to avoid just to keep wiring nicer. It looks like there's no way to disable charging or set the DVCC limit to 0 over modbus without ESS, is that correct? Any workarounds?
