Batrium BMS Monitoring

Hope this is the right place to post this. I wrote a bit of python3 to monitor my Batrium BMS. You can modify it using info here: https://github.com/Batrium/WatchMonUdpListener/blob/master/docs/WatchMon%20Wifi%20UDP%20protocol%20sw1.0.30%20v1.0.pdf I plan to incorporate it into my pvoutput upload sc...

Its just a binary you run and you can pipe data to it (STDIN) and it replies over STDOUT. So you can treat it like a terminal.
Nice!

Re: PIP-4048MS inverter

Forum user hwassie published a Python program to read the data from a PIP and upload it to a database. I was more interested in pvoutput.org where I already graph my old Xantrex system, originally with an Arduino using some code I open sourced and then more recently with something on a RaspberryPi t...

Re: PIP-4048MS inverter

I bought one of these clones. It came with a parallel kit installed. Parallel mode was enabled. So far, I haven't been able to install Coulomb's firmware but I haven't tried since I turned parallel mode off. It is however working quite well and I will probably buy a second and possibly third one to ...

Re: Brighsun 220Ah cells

I bought 8 cables claiming to be 2 AWG 35cm long with terminals on AliExpress for 2 x $28. Probably bad value given I have a hydraulic crimper but it made things very simple.

Re: Off-grid solar diagram / ideas

Hi John, this one is an extremely contentious issue among members here regarding the requirement for blocking diodes. We are not far out of Adelaide up in Mannum so if you are interested in a visit drop us a PM and we will arrange a time etc Love a good contentious issue! Can't see it doing me any ...

Re: Brighsun 220Ah cells

Those interconnects are so nicely fabricated!

Now I'm going to have to do it properly or hide the photos forever.

Re: Off-grid solar diagram / ideas

Terry, I think you need to be careful about putting panels in parallel. I have read a few articles on the need for blocking diodes to prevent shaded panels from sinking current from generating panels. https://www.electronics-tutorials.ws/diode/bypass-diodes.html I have bought 25 250 watt panels rece...

Re: Off-grid solar diagram / ideas

I was contemplating a diode across the contactor which took me off to the world of high current diodes. I'm going to wait and see what Batrium can do. It has multiple outputs and inputs and places for logic. I've got the software running in a VM on my Mac so I'm almost ready to play. In another part...

Re: Off-grid solar diagram / ideas

I'm basically building this.

The main contactor on the battery may be replaced by a good software control system but I appreciate the value in a contactor driven by a BMS.

Each solar panel is actual a string of three.

I found 16mm M8 bolts on ebay. Bolt Stainless Steel Metric Coarse. $23 for 50. Same vendor had split washers too.

Re: Brighsun 220Ah cells

I have bought 16 Batrium BMS modules of the terminal + flylead variety. I'm having some regret because it would have been easier to use the dual flylead modules but it doesn't matter. I'm planning on using aluminium links like Steve. Thanks for the Alvania tip :-) My PIP inverter just arrived and I ...
