Batrium WM4 & ext2 - how to switch a load
#11
many reasons...
But first I wanted to have all components to 1 display.
The 123BMS has can-bus but no chance to connect to Victron Venus.
So I searched for a compatible bms.
I just found REC and Batrium. Most voices out there recommended Batrium.

Second
I had lots of problems with the old BMS, it was not good for the mobile use. So I decided to change now.

Using your Batrium and a Venus device together will give you lots more options for making beneficial use of opportunity loads, as opposed to just using the WM & expansion, but you will need to acquire a fairly in depth knowledge of how both systems function in order to take full advantage of all features.

Victron will point you towards one of their approved dealers for installation and configuration help and assistance (which will have cost implications) but their online documentation is very well laid out and comprehensive if you wish to do it yourself. The Batrium documentation isnt quite so well laid out but it is finally now fairly comprehensive, so the DIY route is open to you, with an assumption that you are able to correctly comprehend technical detail.

By pointing you towards their documentation Batrium are simply saying the same as Victron will do (as will any other manufacturer of components) which is that they cannot be expected to offer zero cost support in assisting you with the integration of their product within your specific system.

I just use the voltage to trigger my HWS or Criptocoin miners set the time to 1000seconds rather than 30 seconds to turn on and off. I havn't tested it yet but want to missuse the SOC in charging logic to control the HWS (control logic>discharging>SoC%)

Do this in your solar charge controller - most will have a relay that will switch on when in float and switch off when the voltage drops to the re-bulk setting, or the mppt goes to 'sleep'

I use the float relay in my outback FM60 for this.

@Sean
with Venus I could use the "generator start/stop-option" but this won't work because for start you need to have a "lower soc" and for stop a "higher soc". it's not possible to change this. I already tried ...

@ HughF
my solar charge controller has no load or relay. This was my first idea...

@hbpowerwall
I will try this ... maybe this works. Thx

The easiest way would be a possibility to use the BMS directly as I had it before.

Just checked It could work, but what preset would be the one (hardware>expansion>output funktions>relay2) ?

Because if I can't decide, the BMS just stop discharging at all.


For now I'm using:
Output 1 as Charging on, 
Output 2 as Discharging on, 
Relay1    as Critical,  

just as a test I took soc%  cutout /resume    100% and 95%
