Have a 100/30 hooked up to two 175W panels. Been using it fine for about a month now. Out of the blue, it has stopped working. It charged the batteries up to 92% and then output 0W (sometimes 2-3). I unplugged everything and replugged it back in and it worked as normal again for a few hours. Then back to 0W (still reading a nominal amount of V both from the battery and from the panels). I unplugged and replugged again, this time it worked for a few minutes. But then stopped. I repeated the process and now it's not charging at all.

I have checked all the connections with a multimeter and everything appears tip top. One thing I noticed is the voltage reading from the battery terminals of the controller do not match the voltage reading from the batteries themselves.

I also wondered if it was my battery monitor being wrong, but when I turn appliances on, the charger still refuses to output any wattage. Is my unit defective? Or is there something else I should try that I'm missing?

I updated the Venus Gx to the latest software, 2.31. Now, when I connect to it via the build-in WiFi, it keeps kicking me out. Every few seconds I have to reconnect. Any ideas?

I've had a BMV-712 Smart for about 2 months. Now there is no display and the app will not recognize the unit anymore. The power has been checked and is working and the other connector has been removed and reinstalled on both ends. Any ideas?

I have 2 12v 160W solar panels wired in parallel. They are wired to my batteries and a MPPT 100/50 SmartSolar Charge controller. The system has been working fine for the last two weeks since I set it up. Yesterday, however, I came out to find that the victron connect app is showing no wattage or voltage coming into the charge controller from the panels. I have measured the current coming in from the solar panels and there is no problem there. They are showing the voltage i expect. The polarity is correct from the battery connection as well as the solar panels to the charge controller and has never been connected wrong. My charge controller is showing no error code on the led light. The bulk led is flashing once every 3 seconds.

Did my charge controller go bad?

Hello,

Does using the Multiplus II optional current transformer remove the need for an energy meter when PV is connected on the input side of the Multiplus?

Hello.

I have a Victron Quattro, CCGX panel, VE Bus to NMEA cable and a VE CAN to NMEA cable.

These 4 items are all connected as per Diagram 1.1 here:
https://www.victronenergy.com/live/ve.can:nmea-2000:start

Data from the Quattro reports fine on the CCGX (NMEA bus OK) - However I am unable to change the Quattro’s mode (On/Off/Charger Only).
The CCGX screen shows the mode change, but nothing actually changes on the Quattro.

Further down on the page link above I did notice that the VE CAN is stated as being “read only”
CCGX does not send any information to the N2K network.

Does this mean the CCGX it will not send out the required data to request the Quattro change mode?

I must add that what I am ultimately trying to achieve with this equipment......

1) I want to have the ability to control the Quattro ON/OFF from the CCGX panel.

-I do not need (or want to) to send any commands from our systems NMEA network to control the Quattro.

2) I would like our vessels NMEA network to be able to monitor the running state of the Quattro.

Hello,

I have just installed Easysolar 24/1600/40-16 and Venus GX. I have connected Venus GX with ethernet cable to Easysolar's left RJ45 plug. I have also succesfully added Venus GX to VRM, but I cant get it connected to Easysolar. Should it find it automatically or do I need to do something?

I get no information on VRM atm. Only Venus GX online...

I have a Quattro that is charging a large 24v lithium battery set up with the two signal BMS support assistant to control the BMS charging. I can't seem to get the quattro to prioritise the inverter to consume the battery power, in fact the only way I can stop it taking energy from the grid or solar inverter is to isolate the mains input. Do i have to have a Venus GX or Colour Control to set this up?

Any help would be appreciated.

I’d like to use a temperature sensor connected to my BMV 712, and have my MPPT 75/15 receive that temperature data wirelessly. I currently have a shunt connected to monitor battery battery voltage, but there’s only room for one shunt to be connected to the 712. I can find no manual specific to the temperature sensor, and the manual for the 712 does not provide enough detail on connecting sensors/probes.

Three questions:

1. If I connect the temperature sensor probe, does it also communicate battery voltage to the BMV 712, or must I have two sensors installed, one for temp and one for voltage?

2. For the temperature sensor to function, do I need to select the temperature as the auxiliary input on the BMV 712?

3. And if I do need to set temperature as the auxiliary input, then how do I get the BMV 712 to monitor my starter battery in addition to my house bank?

Regards,

Ed

Hi, we have an off-grid installation and have ordered 2 units of B-Box 10.5 LV batteries. After orderind we saw Victron blogs with next info:

[image]

Is that mean that the only way is to change the batteries for example to B-Box Pro? We plan to use it with Fronius Symo 15.0 + solar panels + Quattro 10000 (3 units) in 3 phase system.

Now we have next situation: when we turn on the B-Box L without any consumers it wors ok, after that we connect color control GX and it found the B-BoxL and show all the spec. But when we turned on th B Box L alredy with connected CCGX the battery goes into error.

So the question should we change the batteries? And why the similar B-Box pro is ok for off-grid and B-Box L is not suited?

Thank you!

Hello Victron community,

I'm about to end my camper van conversion, and it's time to set up my electrical devices !

My system is the following : a multiplus 12/800 inverter/charger + a li-ion 160Ah battery + SmartSolar 100/30 + BMV 700 + VE.BUS BMS + DigitalMulti Control.

I read in the VE.BUS BMS manual that I needed to install the AC detector in order to restart the Multiplus. So I did, but it seems that I have now to set up correctly the multiplus with the "VE.Bus BMS assistant or the Self-consumption Hub-2 v2 assistant".

My question is : What is this assistant, and how to load into my multiplus ? Do I need the MK3-USB interface ? It's not so clear in the manual... I currently set up the Multiplus with the DIP switch only.

Thanks for helping

I installed a Victron 200w Bluesolar panel and a Smartsolar MPPT 100/20 in my Campervan, charging one Victron AGM 110Ah/12V battery (I'm not a heavy consumer on power).

I used the 'Gel victron deep discharge (2)' presetting on the MPPT for this battery. This looked fine to me for my Victron AGM battery specifications.

Until now I was completely dependent on two Victron wallchargers, one 15A used for the AGM battery and a small 5A charger I installed nearby the lead-acid battery of the car.

But now that I am no longer dependent on fixed power and love to stay for weeks at the same location without moving or using the engine, I have to find a way to keep the car battery also fully charged. And this is especially important for the following winter.

Unfortunately, the roof of the campervan is not very large, and together with the 200w panel, roof domes, etc. I see no way to install an extra small solar panel on the roof to topup my car battery.

Another option would be to use my Victron Phoenix inverter and connect the small 5A charger to this inverter outlet to topup the car battery, or is this a stupid idea and not possible

I would appreciate very much your suggestions.

if i put 2 LFP battery 12.8v 60 amp in series and the starting current for the truck reach 600 Amp what happens to the lithium battery?

Hi,

If you see below on the screen shot from the Display Console, it shows as PV max 2019w. The panels I have in my place is 6 x 305w panels which totals to 1830w.

Can somebody let me know if this is an issue? Please advise

Hello

I can’t decide between these two MPPT units,

150/35 or 100/50

Currently I have two 12v 165ah batteries in parallel,

and two 100w Renogy monos wired in series.

My concern is in the future when I purchase more panels and batteries for my system (my battery bank will always be 12v), which controller will be a better bet, leaving me with the most options? Having a 150v max input is definitely a great benefit, but does that benefit in series voltage trump the loss of 15 output amps (when compared to the 100/50)? What is the benefit of 50amps vs 35amps?

Please someone help me understand

According to Victron charts the 150/35 is a step above the 100/50...but I don’t understand why as they seem to be the same basically in as much as power.

I guess Ill need to buy a BT dongle, but if I do will there be a setting for LiFePo4 cells?

I keep blowing the inline fuse between the battery and victron inverter , I have a 125 amp fuse installed , I did find the positive battery terminal quite loose after the last fuse blew could this be the cause ? I have 3 x 120 amp hour AGM batteries installed to supply power is the 125 amp fuse the correct size to have installed ?

Hi!

I just bought a Peak Power Pack 8 Ah. This seems like a very versatile product!

In the online documentation is stated max 25V on the car/solar charge input. However in the manual I got with the product it states max 20V. The difference is of big impact since many solar panels have an open voltage of about 21-22 V.

Can I hope that it is an error in my manual, or does the delivered product support max 20V?

Manual:

Version 00, February 2016

Product marking:

PN: PPP012008000

SN: HQ1616LU24Y

v1.08

Thanks in advance!

I am re-installing a MultiPlus as an ESS-system where it initially was designed/configured as a OffGrid system. There is an energy meter on AC1 to measure incoming AC coupled solar.

I set the ESS for 'No Grid meter' but still it is taking the solar meter as input for power balancing, leading to trying to charge the batteries from the grid even when they are almost full and plenty of solar is available.

Disconnecting the meter from the CCGX got rid of this behavior.

I need a way to provide accurate battery voltage to my Smart Solar MPPT (it is off by as much as 0.3-0.5 volts). Based on the victronconnect live manual, and my MPPT part number (SCC010085210), VE.Smart Networking is not supported. However, the same manual states that the new VE.Direct Bluetooth Smart dongle (part number ASS030536011) is compatible with VE.Smart Networking.

A couple other details. I need to be able to still control the MPPT via victronconnect. This leads to two additional questions:

1. Will I still be able to configure/enable/disable the MPPT via my phone if it is connected to the VE.Direct Bluetooth Smart Dongle? I ask because of this note here that says I will lose bluetooth from the MPPT if VE.Direct is in use.

2. Can the dongle communicate with the "Smart" network (the smart battery sense specifically) AND also communicate with my phone via bluetooth? I ask that because the documentation says "Only one phone or tablet can be connected to a dongle at the same time. Make sure no other devices are connected to the dongle, and try again." This is stated both in the dongle live manual and in the victron live manual.
