Was fortunately quick to get into the settings. Just used my friend Gemini. If I had to watch videos etc I would have given up 🤣.

@cavedog the balancing was set already to start at 3.4V. So, it seems I am balancing for quite a while everyday already, maybe some 1 hour or so. Would explain why I keep seeing improvement in the SOC each week.

The guys at Omnivolt seem to have set it up decently.

Why does it show timeout?

Did it connect and read the parameters without an issue?
 
Also if you want to be extra safe set single cell over voltage protection to 3.6 volts.

Just in case some clouds decice to cause some extra charging amps.

Yeah, I think that is a timeout bar. Not sure.

But I was able to change the settings. I closed the software, reopened and read the settings back and they were updated.

Which part did you struggle with?

Basically I set my inverter battery to 0 (make all dip switches off). You will get an error on inverter but ignore.

Then hook up the USB to RJ45 to the free RS485 ports (can be either).

Open the software version 2.4. I didn’t try any other.

And it auto opens the port. Also can check on device manager of your app if the right com port is chosen under ports and coms.

And that’s basically it. When done just revert he dipswitch to 1 and the inverter will restablish comms to the bms.

I never removed my cable for the BMS to inverter. Just used what was left free which was the additional battery comms ports
 
Basically I could not get it to pick up anything with the app but I did not changed the dip switches that might be the reason.

Will check now thanks for the info appreciate it.

Couldn't change the address on the app to 1 on my side, as it assumed the internal battery must be at zero. So I changed the battery to zero temporarily. Didn't want to go through the trouble of making it 0 permanently, even though the SRNE manual says that. Never checked what the Onivolt manual says.

Why does the battery address matter? Surely this is only a thing when you have more than 1 battery when one is master and the other is slave?

If the software is trying to read address 0 but your battery is set to 1 then no comms will be made.

I couldnt change the read address on the software to 1 so changed the switches to zero on the battery itself.

Just checked and its working. Just needed to flip the dip switch to off :X3:

Just remember to turn it back to 1 after if you have comms between inverter and battery. Your inverter will look for the battery on 1. There is a way to make the inverter look for it on zero but too much trouble.

Makes sense because isnt zero the master address?

Maybe zero is for CAN?

I believe so yeah. So the internal battery should be at Zero but I dont have a second battery so it is a bit pointless playing around with it to get it to zero.

Comms is done between inverter and battery with RS485. Comms to PC also with RS485. Havent needed to use the CAN yet. Even if I had another battery it looks like you use the free RS485ports.

CAN might be for a battery that uses that for its comms so you use CAN for the battery to battery comms.

I think its inverter dependant if its CAN or not.
