Just wondering why Victron has such a weak Bluetooth signal in most of their products?
MTTP about 3 metres, Inverter about 50 cm BMV about 10 metres...
It is a shame that the Bluetooth is not really useful as it stands...
Any way to let Victron know about this crippling issue?
I was looking for a phone number or an email, but I can't seem to find it on their website...
Hi @Burt65
Now you gave us some more info and the "mystery begins to unravel"... :-))
The MPPTs and the BMV have plastic cases. The inverter has a metalic one.
Add that to your metal wall and you'll pretty see that the inverter range is limited by 2 (two) metal walls, not one like others two... A strong case of a Faraday cage.
As for relocating the antenna, the bluetooth module is a small module with the antenna on the PCB.
And the module is soldered on the main board, so relocating it may be difficult.
So, unfortunately, I believe you have to get used to this situation...

So you reckon by removing the front cover of the inverter I may get a slight better range to pass the wall like the other devices... I did think about the difference between the two material and was also thinking of cutting the front panel and just have an acrylic window in front of the board...
PS
Different question... Do employees from Victron get access to this forum, or is community only?
Multis and quattros don't have bluetooth.
It is only intended for local, near-distance monitoring, and for small installations for creating ve-smart networks.
You can improve it on the Cerbo with an external dongle, but for what it was intended, it is fit for purpose - personally I get better distance than that, depends what is in between.
As a means of connecting devices and building scalable systems, that is intended for use over CAN, vedirect and Vebus wired networks.
@Burt65 using a term like "crippling issue" pretty clearly defines a complaint, LOL.
Victron does not have a direct support or complaints line - they're a manufacturer, and do not sell to the end-user. Your path of support is through your authorized distributor, as detailed in the Victron Support page.
That said, what you're experiencing is to be expected - bluetooth, by nature, is extremely susceptible to EMI and RFI, not to mention physical obstacles, and your inverter/charger has a lot of all of the above, so will have lower BT range than pretty much any other VE product on the market. Just the nature of the technology, really.
As mentioned it is designed for local monitoring. Yes I found you need to be fairly close for initial programming, but for monitoring purposes I find ~15 meters from inside my home to my travel trailer outside perfectly adequate. Outdoors without any obstructions the distance is further of course but I've never tested its limits. If you want to know what Victron hardware I'm using it is listed in my profile.
Unfortunately, my setup is behind a metal wall. But because the two MTTP have no issue sending the signal through the wall, and the BMV can easily achieve 10 metres, I was wondering why the Inverter can't do it.
I was actually looking for an email or a phone number to contact Victron and see if they have a solution. I need the Bluetooth to work the same across the entire range of Victron products I have, not just for some...
Come to think about, it is not the signal out the issue, but the receiver sensitivity of the Victron Bluetooth in the inverter that is very limited.. It could be just a matter of relocating the antenna if possible..
I can pick up my mppts and smart shunt from almost 15m.away through several walls in my home.
Where I placed WiFi access points affects it quite drastically. Have moved the AP off to one side of the house, and voilà, from my couch I can now see them.
The remote console over LAN is just as awesome.
BLE has a standard. If you walk 15m away with your BT earphones on they will disconnect. It is normal for a range. But reconnect you have to be closer.
You haven't told us which inverter you're using. So it's difficult to help.
However if you have a VE.Direct port on it you may be able to use the VE.Direct to Bluetooth interface, placing it outside the metal wall.
