Wrong idle AC current via VE.direct from Phoenix Inverter 12/800

I operate my Phoenix Inverter 12/800 together with a Blue Smart 100/20 and 2 parallel 100 Ah batteries via VE.direct with the open source solution "solaranzeige" on the Raspberry PI 3b+

I have the problem that the idle AC current is read with 400mA. After connecting a load e.g. pump or refrigerator the values of the AC current will go back to real values.

Since correct values are read out when the load is connected, I do not think it 's a problem of the "solaranzeige" solution.

Also I tried to read #VE_REG_AC_OUT_APPARENT_POWER but I got always a static vaule of Hex: 705220225

I hope I can get help from the community here.

Many thanks in advance.

And best regards from Germany

ColorControl GX and BlueSolar 150/70 connection problems with Ve.direct

Hello everybody,

my system worked perfecelty over last 1,5 years. A few day ago, suddenly, the MPPT wasnt shown anymore on the CCGX. When I reboot the CCGX, MPPT will be shown for a few minutes and then it shwos "not connected".

I tried to eliminate a hardware problem.

- I tried another VE.direct cable and the same problem arises.

- I tried the other VE. direct port on the CCGX and the same problem arises.

- I tired a VE.direct bluetooth dongle on the BlueSolar. It connects without any problems and doesnt loose the conncetion, so the VE.direct port on the BlueSolar is working.


Putting it together: neither the Ve.direct port on the CCGX, nor the VE.direct port on the BlueSolar, nor the Ve.direct cable is the problem.


I really do not understand and please need help.

Thanks in advance,

best,

Daniel

How do I enable Synchronized charging for BlueSolar MPPT?

Hello

My question is if there are known problems with synchronized charging between Bluesolar and Smart Solar devices (in my case both mppt100/50)?

I expanded my system with additional panels and a new smart solar mppt 100/50 charger. I already had a Bluesolar charger, also an mppt100/50 with a BT dongle. They are connected together over the VE Smart networking (Bluetooth) for the purpose of synchronized charging. There is also a Smart Voltage/Temperature sensor attached.

As far as I can see the synchronized charging does not work at all. The switch together into absorption mode, but apart from that they behave totally different. Despite having the same settings, the absorption/float times differ sometimes quite drastically.

I have compiled a very detailed description of the setup and the problem. It can be viewed here under this link.

My first off-grid system design. Would appreciate feedback & critique

Hello all,


After many months of learning, I have decided to take a stab at designing the electrical power system for our off-grid van. I have a diagram of the system attached to this post below (Also hosted on imgur for high-res).


I have labeled everything except for fuse and wire sizes as I'd like to get some feedback on the general connections before I get into wire/fuse sizing.


A few extra questions/concerns I have:

- I have seen similar systems with 2 POS and 2 NEG cables feeding into the MultiPlus after the Class-T fuse following the positive bus bar. I have also seen systems with just 1 set of cables. For this system, which one would suffice?

- I have seen similar systems with 150A fuses coming directly out of each battery before they join at the positive bus bar. Would I benefit from this or is a 500A fuse sufficient coming out of a parallel battery arrangement.

- What type of solar panel arrangement would you recommend for this system (S/P/S-P)? I mislabeled the diagram (I named it Parallel but it's wired in Series)


This has been an amazing experience immersing myself into an area I knew nothing about just a year ago! This community has been awesome, can't wait to hear back!


Thanks,

Manny

VictronConnect cannot connect to SmartSolar MPPT150/85 when VE.Direct cable attached


Whenever I attach a VE.Direct cable to my SmartSolar MPPT 150/85 (VSS-MPPT150/85-TR) it is no longer possible to see the controller’s data over Bluetooth. I noticed this when I installed a Venus GX in the summer. The “fault” has the following characteristics:


With the MPPT as “stand-alone” the app rapidly goes through the routine of “Connecting, Default PIN (at bottom), 0% up to 95%, Fetching Data” before the display values are given.


With the MPPT connected by VE.Direct (even when the other end is not plugged in to the Venus GX) the app goes through the same routine of Connecting, Default PIN (at bottom), going rapidly from 1% to 95%, “Fetching data” appears and it cycles on this for about 10 secs before returning to “Connecting” in an endless loop. Whilst this is happening the display screen has a smeared, Vaseline appearance.


I have played with connecting and disconnecting the VE.Direct:

  • Using a VE.Direct cable:
    • Pulling the VE.Direct plug from the MPPT causes the MPPT LEDs to flash and the app immediately shows the display screen
    • Pulling the VE.Direct plug from the Venus GX causes the MPPT LEDs to flash and the app immediately shows the display screen
  • Using a USB/VE.Direct cable:
    • Pulling the VE.Direct plug from the MPPT causes the MPPT LEDs to flash and the app immediately shows the display screen
    • Pulling the USB plug from the Venus GX causes nothing to happen.


All of the above are true whether the Venus GX has power or when there are/aren’t other devices connected to the Venus GX. The firmware of the MPPT is v1.50 and the GX is v2.18. VictronConnect is V5.33.


I also have an MPPT100/20 & MPPT100/30 connected to the Venus GX. I do not have this problem with them.

How to wire my Cerbo GX to the rest of my Victron components

Hello all,


I'm a bit confused with how to wire my Cerbo GX to the rest of my components in the most optimal way. I'd like to be able to view the status of my system on a mobile device via bluetooth and also view the Cerbo GX web application from that same mobile device.


I have the following components:

- Victron SmartShunt

- Victron 12/3000 MultiPlus

- Victron SmartSolar MPPT Charge Controller

- Victron Orion Tr Smart DC/DC charger

- 1 VE.Direct Cable


The obvious connections to me are:

* MultiPlus -> RJ45 -> Cerbo GX

* SmartShunt -> VE.Direct Cable -> Cerbo GX

* SmartSolar Charge Controller -> VE.Direct Cable -> CerboGX


Here are a few questions:

1. Do I still need a VE.Direct Cable for the SmartShunt and SmartSolar Charge controller since they're bluetooth? Or is the bluetooth only so I can see them within the VictronConnect app via bluetooth?

2. Is it possible to monitor the Orion Tr DC/DC in the Cerbo GX?

3. What are the main differences between what you can view from the Cerbo GX versus what you can view within the Victron Connect app?

Good USB Hub for CCGX with low power draw or Relay shutoff for inverter?

I use a CCGX, BMV-702, 3 MPPT's, and 1 USB wifi dongle.

Since there are only 2 VE direct and 2 usb ports, I need a usb hub to get my 5th connection point.

Currently, I have a crappy AC powered usb hub on the old phoenix inverter (That doesn't have ve direct port, Insert angry face) and the inverter is in ECO mode.

The USB hub is the only AC load on my boat, and I only really need it to send the wifi to check the system.

Is it possible to use the relay on CCGX or BMV to turn off phoenix inverter using it's remote port at night, when I don't need to check the wifi?

Or should I just find a low powered USB hub that runs on DC? (Does anyone have any recommendations?)

Every night, my BMV says 100% but the AC inverter is powering the USB hub through the night, and it uses about 2% of the bank and 96 watts. Is this slowly killing my batteries? Should I not be worried about this daily 2% discharge?



Thanks,

Updating firmware MPPT 150/100 VE.Can using VE.Direct + PC software

Equipment:

MPPT 150/100-Tr VE.Can connected to PC using VE.Direct port & Victron serial adapter cable.


Scenario:

When connecting to Equipment via the VE.Direct port with Victron serial cable + PC with VictronConnect software, we are prompted to update the firmware on the device, which then fails (see attached error message: "Update failed! Result: X88 - Communication Error. Vreg Ack timeout. Please check the connection and try again". See photo for error screen.

Question:

Any idea how to fix this so we can update firmware via PC and configure settings?


Notes:

  • We are able to connect with the Android App and perform the update via Bluetooth. Subsequently the connection using the VE.Direct port + PC works fine.
  • We're using the latest version of both the PC VictronConnect software as well as the Android app

If you have any ideas on how to fix this it would be appreciated, as we're expecting to be programming many of these devices and doing so via bluetooth is very time consuming.


Thanks kindly,

Does anybody have a way to combine VE.Direct text streams? It needs to be RS232, my controller won't support TTL.

Otherwise, is there anyway of hooking into a VE.Smart network to get all the data from connected devices?

Connect BMV shunt Wirelessly to Cerbo GX?

I have an RV installation where my batteries are in one bay, and a Multiplus and Cerbo are in a separate bay. Due to how the batteries are wired, the only place I can install the shunt is in the battery bay, and there is no space to have the Muliplus in the battery bay.

The problem comes from my inability to run a cable between the two bays. A wireless bridge for the VE.Direct connection would solve my problem. I have not been able to find any solution for that. The closest I’ve come is using the VE.Direct LoRaWAN module and a gateway to connect to VRM, but that does not get my battery information available locally (via the Cerbo and a GX Touch 50).

Has anyone else faced this issue and found a solution?

CCGX loses connection to VE.direct Charge Controller 90sec after reboot

EasySolar 24/3000/70 Mppt 150/70 that we installed for an off grid client. The system has been installed and working fine for 2.5 years and then suddenly the PV Panel does not show on the CCGX display, device list shows "MPPT not connected". However, the MPPT charger is fine and is charging the battery.

A reboot of the CCGX always brings the connection to the MPPT back to life, however after 90 seconds it loses the connection again. This behaviour is repeatable with loss of connection about 90 seconds after a reboot.

There is no USB hub or VE.direct extension cables in the system and this is the original Victron-supplied VE.direct cable that has up till now been working fine. This is an EasySolar system with the VE.direct cable prewired inside the EasySolar. This is a single EasySolar system with no other devices.

I have unplugged and replugged both ends of the VE.direct cable and the problem is still there. No firmware updates have been done as this system is not internet connected. Is this a cable problem or something else? Why would there be a fault now after 2.5 years of good operation?

Battery disconnect protection for load

Hi all,

I'm using a Victron SmartSolar MPPT 75/15 to charge batteries and supply power to a load.
The system has isolator switches for both battery and solar, however we have found that occasionally the operator will disconnect the battery before solar, OR the battery fuse will blow if there is some system failure.

This cause the voltage across the load ports to spike to full solar input voltage before regulating down. The LVD is too slow to catch this. This has caused damage to some sensitive components attached to the MPPT load.

My question:

I want to use VE.Direct to monitor solar charge, battery state, and load power usage. But the load ports are proving to be risky. Is there a solution where we still get all the benefits of the load port in terms of usage statistics, but mitigate the risk of destroying attached devices?

My original thought was to use the Victron SmartSolar MPPT 75/15 paired with the Smart Battery Protect.. But I loose Voltage and Current stats for the load.

If I use the BMV712 with shunt, and run the load direct off the battery, will the MPPT and BMV712 communicate? What about the floating ground from the shunt..

Ideally is there someway to balance out the voltage spike from the load if the battery is disconnected?

Phoenix Inverter 12/1200 VE.Direct does not show AC out

I can read all the values that the datasheet says is available, like AC OUT Volts is what I expect at about 120.02v. But AC OUT Current (AC_OUT_I) just shows -1 or 0 for me.

I have some experience using VE.direct USB cable with a raspberry pi to read the metrics from the serial port for a BMV so I'm pretty sure I'm doing the basics right.

Example output, includes model and firmware if anyone is familiar with these:


['Checksum', '\xd2']
['PID', '0xA279']
['FW', '0114
['MODE', '2']
['CS', '9']
['AC_OUT_V', '12001']
['AC_OUT_I', '-1']

Feature Request - GX and VRM - Ve.direct devices tracked through unique identifier NOT the device ID

It seems to be pretty well documented that there are issues with ve.direct devices shuffling around device IDs in a system. This is an extreme nuisance for multiple reasons. Firstly, your device history in the GX and VRM essentially get lost. Secondly, if you have a well defined Advanced view in VRM with many widgets, these have to be redone every time the device IDs get shuffled which is a considerable pain due to the interface. While a pretty interface, it is NOT at all an enjoyable process to arrange your widgets in VRM.

I have had this happen twice now in my system in the last 3 days and it is very frustrating and really breaks your historical data used for trending and analysis.

It seems that currently, devices get tracked by their ve.direct device id (288+). This is a transient value that appears to get assigned to devices when they are connected/on power up (or if a random reshuffle occurs?) and is simple a bus communication port. Given that every device has a unique serial number (and likely other under the hood identifiers as well) why isn't data logged against that vs against the device ID which seems to change randomly without reason. This would represent a much more "stable" view into your data and allow me to trust the long term trends much more.


Thanks!

Sure enough, there is such a thing "VE.Direct to VE.Can interface" (ASS030520410) but it is about the same price as the MPPT I want to connect about 300EUR.

Now, I have since learned that you cannot use VE.Can on the MultiPlus II GX for MPPTs but I am still interested in why the VE.Direct to VE.Can interface is so expensive?
