Why do Blue Smart IP22 chargers have no support for VE.Smart?

I have seen others have asked this question for a long time!

What is happening Victron designers? This appears to be a very big omission from your system thinking!!!

All the other components in my system can talk to each other with VE.smart but not the mains charger. :(

Can you please provide an update.

Thank you.

Synchronized charging


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.

Quattro Inverter short circuit current

Hi, All

Our client wants to know the short circuit current delivered by victron quattro 10 kVa inverter. This is for circuit breaker selection. For example, if victron inverter can deliver 160 A short circuit current, will cause 10A, 16A sub circuit breaker trip within 400ms, a 32A circuit breaker will not trip. Does anyone know this value and or from some publish document.

ANL fuse prices / quality

Is there a difference in quality between various makers of ANL fuses? I see single 150A fuse prices ranging from $5 to $25. Does brand matter or are they all the same? (Other than some being ignition protected, some not.)

Also, the Multiplus manual recommends 2x pos and neg cable connection. Should each positive cable be fused for 50% of total current expected?

No data from pylontech battery but connection is made?

Hello all,

I have a Quattro 24/5k/120 x (2), and Cerbo GX, and (3) Pylontech compatible batteries with 400Ah for about 1200AH total. I connected per Victron's Pylontech documentation and see that the Pylontech registers as a present. I'm just not seeing any voltage, current, temps, etc...

Has anyone experienced this? Any ideas where to start looking?

I've confirmed the cable pinout on CAT6 + shielding (run-length about 10'), dip switches on Pylontech batteries, CAN termination, etc...

Quattro firmware is 276 and Cerbo firmware is v.2.60

Pylontech battery reads 0s


Plytontech batteries are connected and talking - not sure if talking properly


Quattro is registering DC voltage from batteries:

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


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


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.



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


  • 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.

Multiplus continuous power limits with non linear loads

I am designing a solar system to charge electric lawn equipment with a Multiplus 24V 3000w. When all 3 lithium battery chargers are on they will pull 2700 Watts which is over the continuous rating. It is to my understanding that these lithium tool chargers are non linear loads. Under the specifications 3000 watts is the continuous rating for non linear loads. Am I correct in thinking that as long as the temperature is kept in check the system wont overload?

Is it possible to use MPPT 100/50 Solar Charge controller just like a DC-DC-Converter without MPPT?

I want to use my MPPT 100/50 1) with a bicycle powered alternator (0 to 75V and 36A, up to 1000W but 100W normal power) at the input and 2) different electrical consumers or battery charging at the output. Actually I need a DC-DC converter with very wide input voltage range.
1) This seems to work fine (with battery at the output) but the MPPT should be switched off to get this working like a normal DC-DC-converter. Otherwise, the MPPT will never find the right point because the input voltage changes to fast. Can I switch MPPT off somehow via VE.direct settings or custom firmware?
2) I didn't try that yet because I fear to destroy the device. Is it possible to directly connect different consumers (e.g. DC-AC inverter, 12V Car Mobile Charger, Car Hifi)?

Today on a very hot sunny day the app is only showing solar panels at 22-35w which cannot be right. All wiring and breakers are ok, and it appears im still charging the batteries as I can see 13.8v showing.

MPPT 75/15 does not load my LiFePo4

I shortly bought an MPPT 75/15, a LiFePo4 12V/100Ah and a Wattstunde 200W Solarkoffer.

I used the cables set that was delivered with my Solar Panel and I believe, they are sufficient for the job.

The battery had a voltage of 13.48V when I connected it. So I thought it was not really empty.

The VictronConnect App shows a solar input of 60-147 Watts.

I expected to see a charge voltage of 14.2V. I expected the charge voltage to be constant.

However the battery stays in bulk mode with voltage between 13.17 - 13.63 V depending on actual solar input. Battery current is up to 7.5A

I also expected the bulk mode to end after some hours, (after a harvest of near to 500Wh in the last two days), as the battery was not empty.

What am I missing?

Thanks for your support

Multiplus Quattro AC frequency Hz variations

I've been trying to get to the bottom of why we have some flickering LED downlights in our house, especially those on dimmer switches. Dimmer switches are notoriousely sensitive to frequency variations.

I've been looking at my Multi's AC Output metrics from the VRM and I noticed that the frequency can sometimes drop as low at 48.34 Hz.

According the Multi's specs, there should be about a 1% variation on the 50 Hz output, which I calculate should only go down to around 49.50 Hz.

Can anyone tell me if this frequency variation that I am having is unusual for a Multi, or is that normal? I am wondering if this points to some type of fault?

This issue is occurring when we are running off the grid on ESS settings.

Multiplus2/Bluesolar limited/throttled solar production


2 x Multiplus ii 48/3000/35-32 in parallel

1 x Bluesolar MPPT 150/70

8 x Trojan T125

18 x Renesola 300w panels 6 strings with 3 panels per string

Running ESS feeding excess to the grid.

I started off with 1 multiplus and 9 panels with average output as per graph.


I then upgraded with another 9 identical panels. The output was capped at just over 2kw.


And after adding another multiplus it is now capped at 3,6kw from 10am to 2pm.


Thinking that the inverter current is derated due to temperature as the internal fans switch on at 09:30 in the mornings already with room temperature between 20-23 degrees C, I have installed 2 120mm ac fans on each inverter and another one on the mppt ducting air into the bottom intakes. Before the mppt was almost hot to the touch, and now cool after installing the fan from 10-4pm. The fans made practically no change to the solar output.

MPPT current at the peak readings is 108V and 33A that is just over 50% capacity. At 3,6kw production the inverter is running at exactly 60% of the rated output. Any suggestions as to why production is limited or capped?
