Phoenix Inverter 12/375 - Venus OS - show AC Loads

Hello, I am new in the forum and german. so excuse my english. I have a Phoenix Inverter 12/375 with the lastest firmware 1.21 connected via to a venus os 2.65-3 on a raspberry connect to the vrm portal. Both, the portal an the venus shows the loads as a factor of 23 Watt like 23, 46, 69 and so on. Why the loads are not the right value? is that a problem by the firmware or general? Will that be fix in the future?

Thank for an answer and I wish a happy weekend.

Greats from Berlin, Germany Norman

Smart Solar 100/20 and SmartShunt

Hi, I am new to this. Just installed a Smartshunt, the Bluetooth range is very poor. Mainly due that the batteries are deep down in the engine room in my boat. If i connect the VE.Direct from the shunt to the Smart Solar will the Smart Solar be able to relay the info on it's bluetooth ? The Solar charger is way better placed than the shunt. there is also a possibility to connect the Bluetooth dongle to the shunt and place it a little better, but will that work ?

Phoenix VE.Direct inverter remote interaction

Can anyone explain how the remote on/off switch on the Phoenix VE.Direct inverter interacts with Victron Connect control of the inverter.

Does the remote switch need to be in the on position to control the inverter from Victron Connect?

If the inverter is turned off from Victron Connect then the remote switch is turned off then back on again, will the inverter start or is it necessary to go to Victron Connect and turn it on there also?

VE Direct LoRaWAN - Voltage measuring

Is it possible that a VE Direct LoRaWAN measures the voltage from it's supply? If yes: does it transmit this voltage to the portal? This would allow to use it for remote monitoring the voltage without any other capable device.

Smartshunt + VE.Direct LoRaWAN are compatible to send SmartShunt data to VRM Portal?

I think to connect a Smartshunt with a VE Direct LoRaWAN, to read remotely the battery State of Charge and other parameters Smartshunt may send to the VRM Portal.

Is this a legitimate, feasible use case supported by Victron? Anybody tested this configuration?

I read VE Direct LoRaWAN manual but I do not see compatibility with the SmartShunt. Thus my questions above.

Below an excerpt form the VE Direct LORaWAN manual:

Product compatibility

This module has one VE.Direct port and is compatible with:

  • All MPPT Solar Charge Controllers which have a VE.Direct Port
  • BMV Battery Monitor 700 series
  • BMV Battery Monitor 712 Smart series
  • Phoenix Inverter VE.Direct models

The module is not compatible with our Peak Power Packs - even though they have a VE.Direct Port.

More information is also available on our website:

Victron charger settings etc via the vrm portal are you able to change these via the portal

Hi all
am i doing something wrong if i use victron direct to my pc with mppt 100/20 connected
i am able to change voltage setting etc with out any issues, when i use my smartphone
using blue tooth i am able to connect to the charger and go to settings and change voltage etc
without any issue.
But when i use the online vrm portal using my rasspberry pi i connect to the portal ok
and i can see my mppt 100/20 ok and i assumed that from the portal i would be also able to change settings
voltages etc but cannot see any setting to do this.
Am i missing something or in fact you cannot change the voltage setting etc via the portal.

MPPT RS case interferes with the VE.Direct connector

I am using a Victron VE.Direct cable with my MPPT RS 450/100. The position of the MPPT case means that the cable plug won't fully seat home in the socket of the MPPT. More than once it has not made a connection between my MultiPlus II GX and the MPPT. This seems like a design flaw and could be rectified by making up my own cable rather than using the Victron cable. Alternatively I could cut away some of the case but would rather not do this. Any advice?

2 Ve.Can MPPTs 1 Ve.Direct

I have a client with a 150/85 Ve.Can MPPT and 1260w of panels but he wants to add 840w more. Both of which charge the same battery bank. The current 150/85 is connected to a Color Control GX via a Ve.Direct cable. If I add another Ve.Can MPPT and use a RJ45 to connect them in parallel will the Ve.Direct to the GX display the information for both MPPTs?

I know that a RJ45 would of done this to the GX per the manual, but I can't find anywhere if the Ve.Direct will work the same.

Or should I just use the Smart Networking to put the MPPTs in parallel? And if I do that will the Ve.Direct send the info to the GX for both controllers?

The two MPPTs will be on different arrays and have thier own wires. It's just a pain to run another Ve.Direct or RJ45 to the GX, plus it will save the customer on labor cost.

BMV 712 Smart to MPPT 75/10

We have a BMV 712 Smart monitor. This year we added a MPPT 75/10 solar controller. I bought a Victron VE direct cable and routed it to both. When the cable is not connected, both units function perfectly. When I connect the cable, the display on the BMV displays all characters. However when connected by Bluetooth to the BMV, it still provides correct battery information. Does anyone know why this would be happening and how to correct it?

Phoenix going offline after change?

Hi everyone! Long time first time.

I recently bought the Cerbo GX unit to add to my existing installation, which has a Victron MPPT Charge Controller and a Phoenix 12/1200 inverter. Prior to the Cerbo, I was using bluetooth dongles to connect to the controller and inverter separately. With the Cerbo, I am using cables to connect both inverter and controller to the Cerbo. I am *super happy* with this upgrade and the VRM portal; however, my inverter has mysteriously shut itself off 3-4 times since I changed the bluetooth dongle out for the cable (24 hours). I was initially worried that it was some kind of software issue, but the more that it happens, I am increasingly convinced that the remote control jumper, which is right next to the port on the inverter, is a little loose, and the normal vibration of the inverter during use is causing it to jostle out of place, which then turns the inverter off. The only way I am able to reconnect is to go to the inverter and jiggle the power switch, re-plug the cable, etc, and it appears that all of these things are mounted on the same piece of hardware inside the device, because they all move in unison when I jiggle one of them.

Has anyone else had this experience? Is this a plausible explanation? Could this be being caused by a software issue instead? I am planning a major upgrade to my whole system and bought the GX first to play around with it. I love Victron products, which are otherwise awesome, and really want to get to the bottom of this. TIA.

ETA: I don't know why this would start happening upon swap-out of the bluetooth dongle -- that sure points to a software issue. But I think it's possible that it just was stable from having not been touched for over a year, and my messing with it caused a new hardware issue.

VE Direct - chain devices for monitoring?

I just got my first Victron controller (BlueSolar 75/15) and am very pleased with it, and finally decided to swap out my old and junky inverter with the very solidly made Phoenix 12/250 unit. So far so good - basically I only need to charge my laptop and tool batteries with 220v when working in the garden.

However I do want to know how much current my inverter is pulling and have that tracked on the Android app (I'm a techie and a bit of a control freak - it's why I'm replacing my garden setup bit by bit with better equipment) and am a bit dismayed that the BlueSolar charge controller is not able to poll the Phoenix inverter for status and current amp consumption (I know now that this is approximate, but hey, it's a garden!). I understand that VE Direct is a bidirectional serial bus, so it would make total sense that a user can chain the devices using VE Direct instead of having to buy a € 50 Bluetooth dongle - or the € 150 smart shunt! Actually, I'd even be willing to pay €2 a month for a premium app version instead...

I am positing that a vast majority of the first-generation users of Victron tech are like me - two batteries, maybe 100w of solar, a good charge controller and matching inverter. So why can't I have the BlueSolar charge controller front the inverter for monitoring?

Am is missing a trick?

connect BMV 700 by VE.Direct to EasySolar II GX- what more must I do?

I have already the EasySolar II GX and the BMV-700, both up and working but not connected to each other.

However I don't get State of Charge information in the Remote Console or VRM portal. The only place I get SoC is on the BMV-700 display.

Since both the EasySolar II GX and the BMV-700 have VE.Direct ports, I have bought a VE.Direct cable, hoping that if I connect them then I will start to see SoC remotely.

My questions:

1. Must I wait until the EasySolar is shut down before connecting the cable?

2. Once the cable is connected and EasySolar is back running, is there anything I need to do to get the two talking to each other?

3. Will connecting them in fact get me the benefit I am hoping for? Or is there something else I should be doing?

Now we have installed a CCGX Fw2.23 and connected the BMV702 via the VE direct port to the CCGX and the correct battery details apear.

Now comes the issue

I then plug the VE direct to NMEA 2000 converter into the CCGX and no data is seen on the NMEA 2000 network

on the CCGX the VE direct to NMEA2000 unit is not seen in the device list

I have tied a secound ve direct to nmea2000 unit just in case I have a faulty one still the same

The targeted result is to see volts and amps on the NMEA 2000 network

How to turn a MPPT charger off to stop overcharging lithium batteries

With Lithium batteries you need to not keep them full charged for long periods. So you need to disable the solar chargers. There is command in to do this (ID 0x2000 device mode charger off) but the manual says this should only be used for maintenance. If this is true how should you turn the charger off? You could reduce the charge current or voltage.

Cerbo GX and 702 and Multiplus - confused

I'm more than a bit confused.

I've just installed a Multiplus, Cerbo GX and BVM702. Multiplus is connected to the Cerbo via a VE.Bus cable, 702 to Cerbo via VE.Direct.

The Cerbo Remote Monitor shows that both the MP and BVM exist. They're also shown on VRM.

However, using VictronConnect via either BT or Wifi the only device that shows up is the Cerbo. I don't see the inverter or monitor.

I had *thought* the Cerbo would let me see and configure these devices. I've since been told I need a Mk3 for the MP. Bought it and when it is connected I do have access to the MP in VictronConnect.

But what about the BVM? Why can't I see that in VictronConnect via the Cerbo? How do I configure that short of using it's screen?

At this point the Cerbo is doing far less than I expected. So clearly I was or am confused about what it can do.

Any education greatly appreciated.

Charge Mgmt - 8 x Smartsolar, GX, BMV, Multiplus

I want to run one charge profile for my Lithium batteries, controlled by both voltage and current fall off.
This means

a) Networking it all together

b) Having a charge profile

Victron seems schitzophenic with their communications protocols. VeDirect, VENet, VEBus, VECan, VE Smart, USB
6 methods. Wow.

So lets assume you have solar with shading. So you want to have one MPPT per panel, to maximise output. That means lots of small controllers. And you want to connect to CerboGX for control.

How would you connect 8 x Smartsolar MPPT in a smaller size to CerboGX?
And once / if you did, you then also need to connect BMV-712 for battery current sense
And also Multiplus II as that charge profile also needs controlling.

The docs for VE.Smart (BT) indicate that the MPPT's will work together, but they are overridden by VE.CAN. Which is not supported by small units.
CerboGX does have BT, but does not support VE.Smart

You can connect VE.Direct to CerboGX via USB adapter, but no info on max qty, or if this will allow control of charge profile

And no discussion in CerboGX of Li charge profile control over Multiplus. Though us hinted in VE.Can info - but Multiplus(ii) doesn't support VE.CAN

Victron - how to make sense of centralised charge profiles for lithium? (Assuming batteries are not VE.Can Victron)
Or - even if they where.

Phoenix Inverter VE.Direct: 32k or 64k firmware image, which one do I need?


I have a Phoenix Inverter VE.Direct 12V 375VA 230Vac that is suffering from a failed firmware upgrade (at least I believe this is what the blinking LEDs are trying to tell me).

Looking at for firmware flash images, it seems that there is a 32k version and a 64k version for my device (12V 375VA 230Vac). The 32k version would be the one with A211 in the name, the 64k version would be the one with A241 in the filename.

I could not find A211 or A241 anywhere on the inverter. Does anybody have any hints that helps in picking the right firmware image?

#10 Alarm system time sync error , #1 device switched off random reboots

For last couple of months my system ( 3 x 5 KVA Quattors in 3 phase with BYD 10 KWH) randomly resets ( all the quartos go offline and come back on)

#10 Alarm system time sync error, #1 device switched off commonly seen.

Initially, I Suspected network cabling so replaced with CAT 7 high-quality cables and cleaned the network sockets with contact cleaning fluid

Also, checked if all DC connections are tight ( they are )

There seems to be no pattern to these switch offs ( observed at 2 am in the night and also during afternoon or evenings ) -

The system works fine for a couple of weeks and in one day I could face one or more restarts with associated error logs

All firmwares are the latest except Quatro which are on V430 ( latest is 464 i believe)


1- Is there a detailed log somewhere indicating which unit is causing the shutdown

2. Should I upgrade quattro firmsware to rule out any other issues

3. Is this the issue of any external EMF affecting the network cabling ( they run parallel to the power cables - not in my opinion as CAT 7 are each pair individually shielded )

Class F channel and Category 7 cable are backward compatible with Class D/Category 5e and Class E/Category 6. Class F features even stricter specifications for crosstalk and system noise than Class E. To achieve this, shielding was added for individual wire pairs and the cable as a whole. Unshielded cables rely on the quality of the twists to protect from EMI. This involves a tight twist and carefully controlled design. Cables with individual shielding per pair such as category 7 rely mostly on the shield and therefore have pairs with longer twists.
