Hi,

I have freshly installed ES-II 48/3000/35-32 230V MPPT 250/70 GX. The devices LCD panel or mobile app nor the Venus IP ”settings page” does not show the state of battery charge at all. What could be the problem and what should I do? How do I know if the system is charging the batteries at all?

I have seen pictures Where the GX lcd panel displays the state of battery charge but in our device that view is totally missing.

Having a strange issue on a new install, which is identical to a couple of others.

With ESS optimised mode the solar yield was terrible, the inverter was pulling most power from the grid. I changed the modes to "keep batteries charged" and immediately the MPPT started delivering power. Change it back and the power drops significantly and reverts back to mainly grid.

I have compared settings and can't find a difference.

475 firmware on a 3kva multi and 2.57 Venus OS, mppt is on 1.50.

Dear all,

I have a strange phenomenon.

When anything is connected to the VE.BUS ports the Quattro switches off. You can hear it trying to switch on again but it won't.

I have an old Microprocessor Quattro.

Devices I have tried to connect to the VE.BUS:

- Digital Remote

- Victron NMEA2000 interface

- Cerbo GX

I have tried changing the RJ45 cable - no help.

As soon as I deconnect the RJ45 cables, it switches on and stays on. Functions normally.

Kind regards!

Hi Community,

my Multiplus II GX LCD Display backlight is always on. The manual says:

"When the GX Card is on, pushing the button beside the screen will increase the brightness of the backlight. The backlight will dim itself again after 5 minutes."

My backlight never dims. When I push the button beside the screen it just cycles through the different info parameteres.

Is that "backlight always on" a known bug or can I deactivate it somewhere ?

Thanks and Best regards

Daniel

Very easy one for experts i am sure!

I recently added another victron smart battery to my bank..

I re-routed a few wires to keep them tidy - like the bms ethernet cables etc then re-assembled as i previously fitted them

When i came to turn the Quattro it wouldn't turn on. The CCGX could not see it ( shown as unknown on the display )

I had to re-start the CCGX. While the CCGX was off the Quattro turned on then the CCGX came on recognising the Quattro and working as normal.

This is still the case. So if i turn the quattro off ( when i park my rv up for the week ) when i come to switch it back on i have to reset the CCGX to get the quattro to turn on.

Is this normal?

System incorporates 3 x lithium smart batteries , VE bus BMS and quattro and Victron smart BMS

Thankyou

JAY

I have the following setup:

Multiplus II 48/5000/70 (v466) with Tsense, Vsense connected, VE.Bus from Color Control.
Bluesolar MPPT 150/85 VE.CAN (v2.05) without Tsense and Vsense connected, CAN from Color Control.
Bluesolar MPPT 150/60 VE.Direct (v1.50) VE.Direct from Color Control.
BMV-702 (v3.10) with Vmid-point connected, USB to VE.Direct from Color Control.
Color Control GX (v2.57) running ESS with DVCC.

The most recent addition is the 150/85 CAN MPPT and after connecting it, the system appears to throttle down the other VE.Direct 150/60 MPPT almost completely. If I turn on large loads the VE.Direct 150/60 MPPT will start briefly but soon stop charging completely.

As per this screenshot for example with a 2.4 kW AC load:

[image]

The 150/85 as displayed is running at its full connected PV capacity of just over 1 kW. The 150/60 MPPT can deliver about 2.5 kW of PV capacity, yet remains idle. As can be seen by the BMV current draw at the top, the battery is actually being run down even though there is adequate PV power available to cover this load and charge the battery.

This persisted until the system went into Bulk with the 150/60 MPPT not providing any sort of significant charge.

When I unplugged the CAN connection to the 150/85 MPPT, the 150/60 MPPT woke up and started delivering full power while the 150/85 continued to provide it's ~1 kW (running in standalone). Reconnecting the CAN reverts to the previous state with the 150/60 dropping to idle. This leads me to believe that this is not a premature Absorbtion/Float issue as I watched the system get to a proper float state rapidly with the CAN disconnected and the 150/85 running.

I have tried toggling DVCC completely as as well as all of it's sub-options to no avail.

Both MPPTs also have the same absorption and float voltage settings and follow very similar cable runs. The only caveat is that they connect to the main battery cable just outside the Multiplus's DC input and not to the battery posts but I don't see that this should be an issue especially given the Multiplus's shared V/T sense connections.

Any advice on how to make the 2 MPPTs deliver full power (at least in bulk) would be appreciated unless this scheme is not actually supported. It seems that it should be. Given that it works with 1 MPPT in external control and a second without.

Kind regards
Craig

Hi, since I've replaced batteries on my Victron BMV - 602S the display show the error you can se on the picture below. Any press of buttons doesn't work. What does it means?

thank you.

I have a Quattro connected to victron smart batteries with a VE BMS. I don't have the multi control.

I would like to be able to switch the quattro between ON / OFF / CHARGE ONLY remotely via the VRM app. Just for example if i forget to switch it when i leave the rv

Currently i can't switch the Quattro via the CCGX - in the console tab it says it is not possible because i have a VE bus BMS connected.

How do i go about this please?

I'm adding solar to a boat that I built and it's docked at my brother's house on the river. His wifi is good, but the boat will be about 120 feet away from the house, so I need a long range usb wifi dongle.

I'm confused on the best solution for the CCGX.

The current documentation (Section 1.6.2) found here: https://www.victronenergy.com/live/ccgx:start#internet_connectivity

says that there are 4 solutions, but only shows the 2 with victron part numbers. What are the other 2 options?

Also, when I google BPP900200300, the result is a 1 antenna device, and the ASUS model has 2 antennas.

Which is better?

Has anyone experienced this weird gap and confusion of information in the documentation?

Any insight would be very helpful!

Cheers,

Mark

I have two Victron MultiPlus-II operating in parallel. Last week 2020-07-24 07:20.23 "VE.Bus Error: VE.Bus Error 17: Phase master missing" We had had no issues prior to that with my Victron’s working almost perfectly for several months. I have Grid and solar and use my system mostly as a UPS for my business and in particular some vaccine fridges I have.

With both Victron stoped and Grid working fine. Restarts failed with several reboots tripping out my entire buildings grid power when the Victrons tried to start up. This occurred even after splitting from parallel. Start up of one or both units saw the same building power failure issue despite no load on the victron's. They would have tried to charge the batteries.

I first assumed it was just one unit as turning it on replicate the issue inside 10 minutes as it started.

An electrician with dozens of Victon's in his care was onsite to confirm the faults after he tried to update the settings. He later found he second unit killed the building power.

Testing now by a knowledgeable and helpful Victron authorized repair site found the same issue before another factory reset found everything working perfectly in first solo then in parallel using a back up of the settings I had on site.

My Concern is every thing was working perfectly. Victron suggested it is not possible for an error to change settings such as grid code which is a very unwanted change suspected in the faults I had on a system which had been working.

Has anyone else found changes in software settings in a MultiPlus-II in parallel or in standalone modes after a fault or error?

I'm installing my Cerbo GX now, and when I connect just my 110v Multi or my 220v Quatro individually, it works fine. The moment I connect both at once, both units shut down and won't reboot until I have only one connected to the Cerbo GX. Is there settings like master/slave I need to set on the two inverters, or is this impossible altogether?

Hi

Anyone know if any progress has been made, or can be made, with the Victron app on Navico NSO plotters and the support for non-touchscreen inputs?

We have an NSO evo2 onboard but not attached to Simrad screens so, therefore, no touchscreen input just the OP50 control or keyboard and mouse.

Suspect this is common in a lot of glass bridge installations on larger vessels.

Thanks, Jon

Good morning,

my Victron System came to life yesterday and now I am starting to play with parameters to learn how everything works. :)

As a first step I tried to set the SOC Limits of the battery to learn if it is possible to survive a night with the battery only.

I set the Minimum SOC to 30% and my plan was to recharge the battery by seting it back to 100% manually as soon as the sun is shining today.

Unfortunately - although I was able to set the Minium SOC to 30% - the Active SOC limit is stuck at 70% and I cannot change it. The battery was went down to 70% during the night and was stuck there as well.

The actual current is at 48,7V and I would like to go down to 47V.

Is there another parameter I have to set ? (Mode = Optimized (with BatteryLife)

Hello Specialists,

I run since several weeks a 3-phase ESS installation with Multiplus-II 3000, 48V, a grid based 3-phase PV and a 8 pieces Pylontech stack with US2000. It works quite okay and perfect. But based on certain circumstances it has behaviours I don't understand. I hope somebody can have a look and give my feedback.

[image]

On L3 is charging a Nissan env-200 with about 3,6 kW. Based on the remote console I see that the systems buys AC energy from the grid L3 with 1,2 kW and 3,2 kW is discharged in DC from the batteries. PV is very low, is equal to 0. The ESS system delivers/buys in total about 4,4 kW energy for a total AC load of 3,9 kW and with respect to yield of converting DC to AC I think this balance is correct.

I understand that a Multiplus-II 3000 is only able to deliver 2,4 kW AC which fits perfect with the grid buy of 1,2 kW to the total of 3,6 kW load on L3.

Question: Why is "no-traffic" on L1 and L2?

There was some time ago a similar discussion from @gnagflow but I couldn't find there a final solution. As I didn't wanted to hijack his thread I made my own question. But in this thread there was the hint:

... you have to turn phase compensation 'off' to get ...

I tried both settings the standard, "total of all phases" as recommended as standard

[image]

and "individual phase"

[image]

but it didn't change in behaviour of L1 and L2! It looks to me, that the Multiplus for L1 and L2 are in standby, isn't it?

I checked what could cause this "unbalanced" answer of the ESS-system. There was no battery discharge limit, it was set for 200A, the battery temperature was normal with 22°C - I have seen in the past discharge value of the batteries up to 180 A for high 3-phase AC loads, so each Multiplus is able to use individually 60 A to do it's job.

In Victrons ESS documentation there is mentioned:

"Phase compensation enabled (default & recommended)

ESS balances the total power (L1 + L2 + L3) to 0 W.

Intelligent optimization of the balance between the phases

ESS intelligently optimizes the balance between the phases -
as far as possible."

"as far as possible" - Where is my missunderstanding or my problem?

What can I do to puzzle it out?

i installed 3x MP2 3000VA /48V. Updated Firmware to 2629474. made ve quick config, setted all settings. made the ess assistant in each MP. Now i try everything but the whole system acts like phase compensation is disabled although it is enabled. each inverter does only deliver so much power as required on the specific phase according to the grid meter. No idea why the compensation setting in the venus gx is not working. Please help!!

AC L1,L2,L3 is connected to MPNr.1-ACIN, MPNr2-ACIN, MPNr3-ACIN. The system is useless. If the electric car is plugged in on one phase with 7kW it only delivers max. 2.4kW from one inverter, if no other loads are switched on. If someone cooks on L2, i only get 2.4kW from the inverter on Nr.2.

I read all installation manuals, the training video on the Victron professional side, there is no hint what is wrong, looks like a software bug on the Venus gx!

Did a search and didn’t find anything on this so thought I’d ask -is anyone using the Load Output to power a DC to DC battery charger, and if so what charger are you using?

I have found a few trickle type chargers that might work provided my panels are producing enough power and my onboard bank is charged.

Basically if possible, I’d like to have the ability to have an “auxillery out” if you will for charging batteries independent of my onboard bank.

As an example, I use my solar electric catamaran as a dinghy to get out to my moored Trimaran. My Tri has an onboard battery but only a small 1A solar trickle charger to maintain it. Sometimes it takes longer than I’d like for it to recover after heavy usage, but I don’t want to install more solar or a full system on the Tri since all it house battery does is power lighting, a stereo and USB ports. It would be nice if I could use my Catamaran, which has lots of solar and a full solar charging system, as a suplemental charger when it’s tied up alongside it. Plus my solar panels on the catamaran are mounted on a hard bimini top that can be angled to track the sun whereas the panel on the Tri is in a fixed position on the fore deck.

I did find a few posts asking about using the 75/15 load outputs as a charger which is not possible, but I’m thinking perhaps those 15A could be fed to a DC to DC Charger. One issue that comes to mind is that my system is 24V and I’d like to be able to charge 12V, I’d have to use a 24V to 12V converter.

Hello,

Can someone help me understand what this VRM widget is for? I was assuming as the widget was showing under the SmartSolar 100/50 that i could pull in temp data from a connected Smart Battery sense as thats the only temp sensor supported by the 100/50.

To be clear the device is installed / paired correctly to the 100/50 as i am seeing the temp data correctly via Victron Connect app but it is not passing the data to the VRM.

I'm expecting to hear that data collected via the VE.Smart Networking feature will not pass data to VRM so my question is why is the widget there and why cant i find any documentation on how its supposed to be used?

Thank you for the help

Hi, the output channel of this MPPT is 12V stabilized?

The voltage is stabilized to 12V or is variable and not there is difference with voltage of battery poles.

Thanks,

Francesco

Greetings,

If I have the Cerbo GX plugged into my BMV-712, MPPT 250/100 charge controller, and MultiPlus 24/3000/70. Do I still want to run VE. Smart Networking between the BMV-712 & Solar Charge Controller?

I could not find a callout for the Cerbo GX. In some manuals, it states ' if you have an GX device that isn't just logging, such as Venus GX etc, disable VE. Smart Networking, Due to possible conflict'

1. Does Cerbo GX interconnect devices and passes telemetry superseding the need for the bluetooth PAN/ VE. Smart Networking ?

2. If #1 is Yes, do I disable VE. Smart Networking due to telemetry conflict?

Thank you.

Will it show the temperature/Voltage in the VRM portal?

..if i link the smart battery sense to BMV-712 to Ve.Smart Networking

..if i used wire temperature sensor to the Stater Battery

Hi,

I have issues with my MPPT as it is not charging the battery. On the attached screenshot you can see that the AGM battery is supplying the load but the charger is not starting. It was days with pure sunshine and it was only charging the first two days. This is now present from more than two weeks.

I know, that the panel needs to be +5V compared to the battery to start charging but to me it seems, that there is a voltage drop and the panal voltage is following the battery voltage.

I already checked the fuse and it is ok. Also the input voltage at the controller is the same as measured in the app.

It would be great if you could tell me, what I am doing worng or what am I missing here.

Many thanks in advance!

New out of the box. I connected 5 panels in series to the controller. Zero volts show up. Then I connected 1 panel to the controller. Measuring voltage across the MC4 connector is 21.0V as soon as I plug it in? Zero volts. Help?

I have a basic solar setup consisting of a panel, battery, MPPT 100/20, fridge, lights and so on. The appliances are connected to the load output of the MPPT. Everything works perfectly unless the fridge overheats because of external heat. In this case the fridge will protect itself by shutting down and blinking its light in a cycle of 4 sec on and 1 sec off. For some reason this cycling will cause all the other appliances to go on and off in the same cycle. The load current is oscillating between zero and only a few amps according to the Victron app. What could be behind this phenomenon?

Hi

I have the 100/15-smart.

I regularly use the direct-load output to recharge small portable things while doing gardening (like tablet and phones and small camping batteries and power banks).

I was under the belief that this output on the smaller MPPT chargers would use "excess" solar power vs taking it direct from the battery.

Is there a function for this that many people use it for like with built-in relay and street-light functions)?

For me I wish it could be monitored by my BMV712 to help me track system usage and would like excess solar to loads so I could charge portable battery devices.

Can it be done with the relays?

Maybe I need to get out my manual and do some more Google-Fu?

EDIT: the reason is a bug/'feature' with non-ascii smiley characters :-(

This has now happened thrice in a row. Ipad, both Safari & Chrome; question ca. 2000 characters long, new verified user.

What is the problem?

"An Internal error has occurred and we are sorry for the inconvenience.

We are doing our best to fix the problem as soon as possible."

I'm adding a Relion RB300 battery to my electrical system (got it very cheap), and want to use it as a solar "header tank" of sorts. The plan is to charge the lithium battery from solar only, and connect the lithium to the AGM bank with an Orion 12/12-30 isolated charger. All boat loads are connected to the AGM house bank. The solar panels charge the lithium whenever there's enough sun, and the lithium in turn tops off the AGM, probably keeping at or near float all the time.

Question is, is the Orion 12/12-30 isolated the right tool for the job?

Regards,

David

Trying to use the Lynx Distributor (and Power In) without the Lynx Ion Shunt or BMS (using BYD batteries). I had assumed the Fuse LEDs would illuminate with a working fuse in place and powered, however a line on the old Victron Live page for DC Distribution Systems suggests that this small data cable is used to power the LEDs (rather than taking power from the busbar itself). I cannot get the LEDs to illuminate - are the LEDs useless unless using the Lynx Shunt? Because Lynx Shunt uses CANbus, it cannot be used in conjunction with BYD on a CCGX (though I think VGX would support it).

Hi

My setup:

Multiplus 2 5000

Byd b box pro 13.8

Im searching for the settings for depth of discharge setting. I can only find it at ESS but its not allowed to activate it running an offgrid version

I would like to shut down the system at 15% and reactivate the inverter at 18%.

Thanks it andance
