I have a Batrium BMS That is connected to the Cerbo gx using the CANBUS. The BMS has a an issue where it freezes for an undetermined amount of time then restarts normally. When it freezes for more than one minute (not sure the exact duration), my inverters turn off. As soon as the CANBUS data is back, the inverters turn on.
Is there a way to program a delay before the inverters turn off?
Hey - I've got a LUA script on a piece of hardware that monitors my SmartSolar MPPT 100/20 and BatterySense.
I swear when I tested it a while ago (previous firmware) I was getting temperature data.
Currently running FW 1.61 and have no temperature (raw serial dump with time stamp) :
023-01-19T08:06:38.088 - SER#1234567890 2023-01-19T08:06:38.093 - V12110 2023-01-19T08:06:38.098 - I-30 2023-01-19T08:06:38.100 - VPV10 2023-01-19T08:06:38.104 - PPV0 2023-01-19T08:06:38.108 - CS0 2023-01-19T08:06:38.112 - MPPT0 2023-01-19T08:06:38.122 - OR0x00000001 2023-01-19T08:06:38.127 - ERR0 2023-01-19T08:06:38.129 - LOADON 2023-01-19T08:06:38.134 - IL0 2023-01-19T08:06:38.138 - H19598 2023-01-19T08:06:38.142 - H200 2023-01-19T08:06:39.075 - H210 2023-01-19T08:06:39.077 - H220 2023-01-19T08:06:39.080 - H230 2023-01-19T08:06:39.084 - HSDS138 2023-01-19T08:06:39.088 - Checksum 2023-01-19T08:06:39.093 - PID0xA060 2023-01-19T08:06:39.097 - FW161
I can see the temperature in Victron Connect.
Anyone able to confirm if this used to work / what happened in v1.61?
EDIT - I re-read the VE.Direct Protocol PDF and see that temperature data isn't one of the fields output on the MPPT units. Can this be a feature request please? Seems an odd field not to have.
I'm getting a charger communication error. Charger disconnects at night.
After then I reboot system, system shows me #67 error code and charger come back.
What can I do for this problem?
What is the best way to get in contact with the Community Manager for site administration issues (accounts, emails, file attachments, etc)?
We have Viktron's Cerbo-GX in a PV System, connected to:
- 6 Battery inverters
- 1 Solar Inverter (Fronius)
- 1 Genset
- blueLog XM200 (red below)
Cerbo-GX is purely in charge of power control, being the master of the system, BUT, we are monitoring the system via blueLog-XM200 (Datalogger from Meteocontrol), which is sending the data to VCOM, the monitoring software.
VCOM calculates the system PR (Performance Ratio [%]), which needs to be compensated with the Correction Value [%] from the solar inverter, this is the percentage at which the inverter is operating: 100% if not curtailed, and lower e.g. 50% if operating at half capacity in order to not inject energy in the grid.
blueLog is getting the Cerbo-GX data via the "Mode 2 Register 2700", but the data we are getting does not allow for VCOM to compensate the PR calculation with the Correction Value, basically because we don't get it, but we get a constant Setpoint Value [W] (this is the value given to the grid meter as limit to activate power control preventing to inject PV energy into the grid). We can not compensate PR calculation with this.
Hence my question is:
- Where is the register from which blueLog can get the Correction Value [%] from Cerbo-GX?
This is a value that all controllers send inverters in order to limit their production when needed, to avoid things such as grid fee-din if the site's power demand is too low compared to PV production.
Hi, i am programming some simple functions on top of the MK3 USB interface. I have read the 'Interfacing with VE Bus MK2 protocol' pdf from the site and i have most of the thinks working. My goal is to implement the AcPowerSetPoint via the MK3 interface.
Does anyone know that the correct MK2/MK3 protocol variable is for setting and getting the AcPowerSetPoint? (aka Grid Setpoint)
When i look at 220.127.116.11 'RAM variables' from the MK2 protocol pdf, i see ID 's 14,15 and 16 and that could be what i am looking for. Unfortunately these ID's don't seem to give the right values.
(Does anyone know the difference between ID 14 and 15? The text is the exactly same for both ID's but they return a different value..)
I'm occasionally getting MPPT state 245. I can't find it defined anywhere in the doco. Does anyone know?
I have several installations in which i used a Victron Multiplus 2 GX and I had some problems in most of these installations, i think the problems that I am facing are related to the communication with the built in GX device.
These are some of the problems that I faced:
1- The screen turned off in 2 installations,
2- The Connection with the GX device embedded in the inverter is not good, no data is transferred to the VRM, noting that all the connection cables are new, it works only after rebooting the remote console, but after some time, the problem returns,
3- The icon of the PV solar charger disappeared and then appeared after rebooting the remote console, but after a few minutes it disappeared, the system saw that there was no PV so the batteries were discharging, Also noting that the connection cables (VE direct in our case) between the chargers and the inverter are new as well,
4- The GX reboots randomly, and in the VRM the inverter appears OFF, the client thought that there was no electricity in the house while is was ON.
Hoping to get some help regarding this topic
Currently I am busy with setting up an Victron ESS system based on a multiplus II and Cerbo CX module. I want to add to this system a third party battery set. Does anyone has experience with the Litech power LiFePo4 48V 100Ah Powerwall Energy Storage system (LPPW48V100AH16S1PF001) (www.litechpower.com) ??
see also the following link: LiTech Power LiFePo4 48V PowerWall Energy Storage System - LiTech Power Co.,Ltd
I was wondering if someone has experience with these battery's or maybe already is using these? Particularly if the communication between the Litech BMS with the victron system is functioning fine.
I want to connect three of these 48V/100Ah in parallel.
Many thanks in advance for replying,
I am looking to extend my system with another inverter. I now have a Phoenix multiplus 24/3000/70 from 2009. I have a HEX number of 1812017.
On the form I read about not being able to connect compacts, phoenix inverters and newer multi's with my firmware. My question is three fold.
1. If I am able to get another Phoenix multiplus with the a simmilar HEX number (beginning with 18) is it then possible to connect them parallel?
2. What cable do I use to connect the two? I only have 1 RJ45 port for my control panel and 2 10pin ports of witch I don't know the name. The manual says it should be possible to connect with other devices from the port. (https://www.victronenergy.nl/upload/documents/Installation%20Manual%20Multi%20and%20Phoenix%20Inverter%20(Non%20VE.Bus%20models).pdf Paragraph 1.6.6.)
3. With the correct cable, will the parallel set than communicate via the old MK2 protocol? Or do I need to install a certain protocol?
See below for pitures of the inside of my current phoenix multiplus.
Hello Victron Community, I am just about finished wiring my off grid 48 volts system also waiting for communication cables from Victron supplier .
The question keep coming up in my mind is what is the best way to daisy chain the system with CERBO GX and Global Link 520. My system consists of 8 Lithium batteries 300 ah sets 2. I have Lynx Power in, Lynx shunt, Lynx Distributor, Cerbo GX , Global Link 520, BMV 712 Smart Shunt with display, Touch 50 , 2 RS 450 / 200 and 2 Quattros 48 volts / 10000 va / 140 amp / AC Transfer Capacity 2 X 100 Invertor 120 Volts. Is it a good an idea to ground Lynx Power in and Lynx Distributor in my system? Please any suggestion will be greatly appreciated. Thank you very much.
I'm new and inexperienced here in the forum, but I've been using the BMV 712 for 2 years. I read and set the parameters under Linux (C, C++) and the hex protocol. I use the document "BMV700 Series HEX Protocol". There are no problems with this. I have now acquired the "SmartSolar MPPT RS 450" and wanted to integrate it into my system, as with the BMV. However, I can't find any documentation on the Hex protocol for the MPPT RS. Where can I find this documentation? Without it, the device is worthless to me.
Problem de multiplus qui arrête pas la charge ou le bms il. Laye c’est tout
Just wondering if there is a protocol converter available that will allow me to connect to either VE-Bus or VE-Can Bus to something like Modbus, if there is a data map available that will also be handy. Looking to pull data from a Multi RS Solar and display on a SCADA system. @Guy Stewart (Victron Community Manager) are you aware of anything?
I have a BMV-501, and Pheonix Multiplus compact installed.
In addition to 'VE Configure software', what components do I need to configure these devices using a Windows 10 PC?
