Feature request: Germany 70% feed in limitation of ESS to the grid

My system: Multigrid 48/3000/35-50 with Venus GX and two connected Pylontech US2000 Plus. A BlueSolar 150/35 is DC- connected to the Multigrid. My Fronius Primo 3.0-1 is AC- connected to the output 1 of the Multigrid. The gridmeter is an ET340.

Now i want to feed in the excess energy to the grid after loading the batteries to refinance my pv- system. If i want to get my feed in energy payed i have to register my system by an electrician to the energy supplier. There is a law in Germany called EEG: Only feed in 70% of all the generators maximum power output. The electrician have to set and confirm that the maximum power feed to grid is set to 70%.

Without this limitation to 70% on the entry point to grid you have to install a radio remote controller to govern down your system in four steps by the energy supplier in case of over- energy of the grid. This controller costs about 1100€ and monthly 5€. Last choice is to cut off all inverts to 70% of power generally.

Further information see: http://www.buzer.de/gesetz/11230/a188267.htm

The technical system and measuring devices are installed, available and working fine at the ESS. Other possibilities to limitate to 70% means an huge technical effort to the whole system and money or a loss of energy.

The Fronius and BlueSolar MPPT can be governed by the CCGX to zero feed in to the grid (works fine) but there is no possibility to govern it to a adjustable max. feed in to the grid.

I need a function to set the maximum power (50W steps) feeded to the grid by the ESS.
Priorities: 1 = self consumption; 2 = loading batteries; 3 = feed to grid with adjusted maximum power
This is an important function to use this system in Germany to feed in to the grid.

I don`t know the exact conditions of the network operators but password protection for the max. feed in value will be necessary.

Is Victron planning such a function?

Feature Request - Rename digital inputs

Hi all

Not sure if this is in the pipeline or not but it would be great to have to option to rename the digital IO on the venus devices.

I already have the smoke alarm and door switch inputs in use but the cummins generator I'm about to install has alarm outputs for the engine and tamper switches on the cabinet doors. It would be great to rename one of the inputs to something like "generator door open" or "engine fault" something along along those lines.

Feature request: ESS Discharge Power Limit

Please consider to add a "Discharge Power Limit" setpoint in ESS setings. Similar to SOC setting, it should only apply when grid is present. I think I will find this more useful for balancing self-consumption with SOC for backup power than my current SOC and grid set point manipulations.

Thank you.

Accessing excess power off-grid with a SmartSolar MPPT charger (for the R&D folks)

In solar battery charger systems, the battery requires less power when nearing the end of charge, but the solar panels (or turbines) can still deliver useful power. This could be exploited for heating, cooling, pumping, lighting etc. However, most potential power consumers draw a fixed power, often more than is available, so a system will cycle or tend to draw power from the battery, depending on how it is configured. For resistive loaded (eg heating elements and led lights) a "dimming" function could be implemented to match the excess power to the load. The dimming PWM output is already available in streetlight mode.

What I am proposing is a software addition that comes into play when the battery reaches float charge. It would implement a control loop to adjust the PWM output so as to maintain the float voltage while maximising the power into the load. The SmartSolar MPPT chargers already have all the input data required to generate the control signal.

The PWM signal could drive a standard dimmer, but might also a Victron new product opportunity. For example, I have a need to direct surplus energy to an 800W 240Vac heating element in a camper-van.

How do I filter on the Connect App Devices screen so I only see my devices?

I am currently drycamping with a plethora of other RV's (400) using Victron hardware in Lake Havasu and have to scroll two or three pages of devices to find mine in that sea of listings. I have named the first five letters of each of my controllers, SBS and the BMV to be the same but my devices are all over the place. It appears VC's default sort is by type of device. I am guessing that the folks writing/doing systems analysis of this software have never used it in a crowded vicinity of their own devices? Maybe boats don't get very close? Anyway, am I missing something obvious or am I, and every other RV'er around me having the same issue? -Bill

BMV712 features requests - Edit 2nd battery name, see temperatures

I have installed my new BMV712 and absolutely LOVE it.

The shunt is connected to measure all current coming out of my two GEL banks.

The voltage leads are connected to each of the two banks - house bank 1 and house bank 2.

Therein is my gripe - it would be great to be able (in the app) to rename them (ie House Bank 2 instead of the generic Starter Batt)

I also have the Bluetooth smart battery monitors on the same VE network - again I would like on the dashboard to be able to see the temperatures of the same batteries.

How to make my phone stay connected longer - as soon as the screen locks it disconnects. Change screen lockout?

Is there a way to reset the max voltage reading short of a full factory reset?

Hope this makes sense - would make a great device even better.

Victron Inverter question

We have a 5kw Victron inverter and this morning the power in our house went. The blue box showed no red overload light (we werent over5kw) just the orange float light. Nothing had tripped on the main breakerboard for the house. It happened twice and then restored itself without intervention after aprox. 2-3 minutes. Please could someone give us an idea of what could be the problem. thanks

VictronConnect improvement request (device selection, syncing data)


there are 3 anoying things in the (Android) App that are stretching my nerves every day.

1. I alwas have to select the device to display after the App was restarted even if I have just one device connected.

Suggestion (3 ways that would improve usability):

  • do not display device select screen if only one device is connected
  • store last selected device and open it on app restart
  • make it configurable (ie.e which screen to display on app start)

2. If the App notices connection interrupt a Popup tells me to check PIN. App does not try to reconnect until that Popup window is manually closed.

Suggestion (3 ways that would improve usability):

  • Display PIN Popup only once
    (usually nobody will change PIN more often than once per device)
  • Retry getting back connection in Backgound and automatically close Connection Interruption Popup when connection is back running
  • make it configurable (i.e. option to permanently ignore connection issues, retry counter, etc.)

3.If the App is switched to background or screen lock is active (just for a few seconds) it seems to drop all previously synced data and starts connecting and syncing everything from scratch when it gets back to foreground. (especially trend graph makes no sense if it always starts with zero data)


  • Just sync new/changed Live Data when App is brought from background to foreground. Store everything else in cache. Do not sync historic data that did not change more than once per day.
  • keep App active in background for a (configurable) amount of time

Feature request: Allow 'DC input low restart' voltage values in VE Config closer to the 'DC input low shutdown' value

When programming 48V off grid systems with lithium batteries, I have found that the the 'DC input low restart' value's minimum 4V above the 'DC input low shutdown' voltage to be way too high.

My feeling is that this 4V margin is intended for lead-acid batteries, but it is not suitable for the much narrower operating voltage range that many lithium batteries have these days.

It is important to have low voltage shutdown set correctly to protect the batteries from over discharge, however, if this does occur the system won't restart again until the batteries are almost full!

I have also found this to be problematic in the event that a system is at a partial SOC (say 40% for example) and it is shut down manually for maintenance reasons. In the process of shutting the system down the inverter experiences a 'DC input low shutdown' voltage (momentarily before it dies). Then when the battery is reconnected the inverter won't turn on until it reaches the 'DC input low restart' voltage which corresponds to a SOC much higher than 40%.


Another feature that would be nice would be to be able to shut the inverter down on a set SOC outside of the ESS assistant. Or maybe this is already possible by way of virtual switch, which I haven't explored much yet??

Feature Request: BMV should show time-remaining as time to full charge, when charging

Would really like to see the BMV time remaining calculation shift from time left on discharge to time-to-full charge (instead of infinite).

Could be done without a lot of display changes, simply by placing a minus (-) sign next to the number showing -hh:mm left till batteries are full, or perhaps even better have that "ceiling" be user configurable to a certain percent. For example I rarely charge my lithium batteries beyond 90 percent so having that ceiling be set to precent 90 (just like the time remaining floor is user settable) would be double bonus.

Victron Firmware Updates - General


Just a general query regarding Victron's version control and firmware roll-out procedure. I get notifications via Twitter that there is a new firmware update (in this case - V2.31 for the Venus GX two days ago), but when i check the downloads section for the updated Modbus TCP Register list, it's still at V2.30 (two days after the firmware was released!). Not complaining, just curious what their typical timeline is for associated documents following a firmware release.

One more thing (this is just a nice to have, again, not an issue). When (say) the updated Modbus register is updated, could the new additions be highlighted in some way for that particular release? Highlight the rows/cells etc. in a different colour maybe? Would help to quickly identify what can be extracted as 'new' data...

VictronConnect for SmartSolar feature requests


The App is quite nice, but what's annoying:

1. the App does not download the data for offline use. Should be easy doable and overwrite internal storage on new connect. Would help to look at the data when away from the camping car.

2. why don't you log more statistics? Would be great to see the sun effectiveness over the day. Would not have to be a minute based view, but maybe one value an hour or so. This detailed info would not have to be kept for a long period, lets say some days would be enough.

These two things would make it a perfect product for me.

BTW. I do use a MPPT 75/15 SmartSolar

Feature Request: Reset generator start/stop logic

From time to time, the auto genstart/stop feature on my Venus device gets out of sync with the state of the generator. This happens primarily for two reasons:

1) Despite my system meeting one or more of the Conditions for auto-start, I decide after the generator is running that I do not want to auto-start this time.


2) While the generator is running, for some external reason unrelated to the Venus logic, I need to stop the generator. Then, Venus thinks the generator is running, while it is not. (And vice versa, in my particular setup.)

In both of these cases, we need a way to tell Venus to "reset what you know and start over" in terms of the logic. Short of rebooting the whole unit, I don't see a way to do this today.

Xx hours before Sunset in Streetlight?


I have a SmartSolar MPPT 75/10 that I’m using to control supplemental lighting in our chicken coop. (Chickens need 13-14 hours of light a day to trigger egg production.)

The SmartSolar controller is the best option out there but it would be perfect if I could have it turn on the load 14 hours *before* sunset and off at Sunrise.

Anyone know of a way to trick it into doing this? As far as I can tell, I’m going to have to manually adjust the timing every week throughout the year.

How can you control relays using temperature data?

As lithium batteries become more popular and they are inherently more sensitive to temperature (both hot and cold), there is an increasing need for relay controls to manage it.

These controls should be accessible via Venus and the Multi programming. They should be able to use the various temperature sensors, either provided by the multi's-probe, temp sense connected to VGX, BMV-712 temp sensor, or that communicated from the battery BMS via CANbus.

This relay can then be used to trigger airconditioning, fans, heatpads, alarms or other circuits and contactors.

Each battery has different temperature requirements, so the programming function needs to be flexible, eg on/off at specific degree, minimum time open/closed, option for time based control, also state of charge thresholds (so you don't flatten a nearly empty battery running a heater when it's not needed).

Advanced next level features could include things like only activate when there is surplus solar available, so batteries are not discharged themselves.

Can anyone think of any other elements of importance when thinking about designing a feature like this?

LYNX VE.CAN-Shunt: Location of the configurable onboard relay

Since the CCGX relay is already occupied by the generator control I wanted to use it for temperature monitoring in the engine compartment and, if necessary, for controlling a small antifreeze heater, since the CCGX relay is already occupied by the generator control.

(see picture above)

Unfortunately, there is no detailed description of contacts on the board for the LYNX-VE.xxx shunts. Where can I find the assigned relay contacts

.... or can I not read correctly again?

One of my wishes from VE:

A simple module (CAN or BUS) for contoling and switching to

MultiPlus SOC dropping when charger in Storage mode and inverter is off


I recently set up a small UPS using a MultiPlus 12/800 and a 105AhC20 AGM battery. Everything works as expected and I'm also running Venus OS on a Rpi 3B to be able to monitor the system.

The MultiPlus is working as standby UPS (no ignore AC settings), so it only uses the battery/inverter if AC goes down or misbehaves.

Battery Monitor on Venus is set to MultiPlus on VE Bus.

I noticed that SOC keeps dropping about 0.5% every day. This should not happen as the battery voltage is 13.4V (temp. comp.) and no load is applied. I also see a strange random load of 1A being drawn from battery. This is probably related.

I was able to catch one, see below...


I been thinking...

Is this maybe caused by temperature compensation? (temp raising so charger lowers the voltage maybe causing false current readings?) If so, this can also confuse SOC calculation?

Any thoughts and help would be very much appreciated.


So, if we had solar/external chargers or loads connected we shouldn't use the MultiPlus to calculate SOC, but if we have a basic setup like mine, with no external charger/loads, I think that would be a good idea that internal calculation could hold SOC at 100% after entering storage mode and if inverter was not being used, so it would ignore 'noise' readings like the ones I get that I think are caused by temperature compensation adjusting voltage.

Setting Tank Monitor Values Manually via API

I have a Color Controller in my motorhome and want to show the state of my tanks on the display. This has been a lot more difficult to figure out that I thought it should be.

Now as you can imagine, I don't want to spend $800 on the resistive tank level adapter, and even then I couldn't figure out what devices to buy to make it work. (It would be cheaper to by a Venus! Why are the adapters so expensive?!)

However I do have a raspberry Pi and could easily program it to tell the CC what the current levels are via an API or Modbus. I couldn't see how to change the values, or even make the tank levels show on the screen. It looks like on Modbus the values are read only.

My feature request is:

- Make it easy to set the values of the tank levels via an API (preferably), SSH command line or Modbus.

Or let me know if this is already possible, but I simply missed it.

I'd also like to see clear instructions on what products to buy for to make it work. Which senders work, what type of senders, which adapters needed for the CC etc. I asked the Victron dealers here in NZ but they didn't know anything about it. There also seems to be a disconnect between the language used by Victron (i.e. resistive, voltage or current type senders) and the products sold in NZ. None of which use any of those terms. e.g. https://www.marine-deals.co.nz/ultrasonic-tank-sender or http://www.rvsupplies.co.nz/products/view/electronic-tank-probe-290300

Any help welcome!
