HARDWARE:
Here's what I have... A 3rd party temp controller turns on it's relay (closed) at 35* or less which is hooked up to aux1 on the multiplus 24/5000/120. when the batteries drop down to 35*, the multi stops charging as it should. I have the remote terminals of the victron battery protect BP 12/24 | 100 connected to aux2 which is operational. I have 6 BlueSolar mppt 75/15 charge controllers with 1 400w solar panel connected to each charge controller. the output of the 6 charge controllers are connected to the in terminal of the BP.
PROGRAMMING:
I have the "2 signal bms" assistant loaded at the top as first assistant. it is configured so when temp controller relay is on, charging is disabled on the multi. next assistant below the first one is a "programmable relay". It's settings are as follows: use solarbox auxiliary relay AUX2 selected, Set relay on is selected, Input signal (auxiliary 1, auxiliary 2 or temperature sense input) selected, did not select any extra drive options, and then set "When auxiliary input 1 is open for 3 seconds. Then the last assistant is another "Programmable relay (1)". It's settings are as follows: use solarbox auxiliary relay AUX2 selected, Set relay off is selected, Input signal (auxiliary 1, auxiliary 2 or temperature sense input) selected, did not select any extra drive options, and then set "When auxiliary input 1 is closed for 2 seconds. with this config the multi stops charging like it should but the battery protect still passes current to the battery. I tried swapping the order of the 2 programmable relay assistant and it made n difference. I need the battery protect to disconnect from the battery. My batteries do not have thermal protection. I looked high and low to no avail and I wold really appreciate if someone could please let me know where I'm wrong here or if there's a better way to achieve this with the current hardware? Yes I have read the assistants doc at victron's site, but I couldn't figure it out with that. A little dense I guess.
Thank you in advance.
God Bless!
