Read EG4 battery SOC at a distance

[Proyecto_Calaveras]

We have a 48V EG4-LL (V1&V2) battery bank and an EG4 6000-EX. The whole system is in a warehouse some 30 yards from the house.

We would like to read the battery information (SOC, current, temp) in a fixed display in the kitchen or via cellphone. The information of at least 1 battery would be enough.

What is the simplest solution to do that? The warehouse has Wifi connection.

Solar assistant can do what you want. Add a tablet and bring up the SA interface and youre good to go. All this assumes you have network connectivity in the warehouse and home.

I read some bad comments about SA. Apparently signature solar doesnt encourage its usage. Have you had good experience with it?

It is the way to go, in my opinion.

Using it with my EG4 6000ex and it works fine. Don’t have it connected to the batteries but it will work.

I am using it to talk to my MPP as well as plugged into each EG4 LL V2 battery to give me details. No issues.

Solar Assistant is awesome.
I wouldn't use any equipment that wasn't compatible with it.
That's how much I like it.

I also have also no battery communication at the moment with my EG4 6000. Which information are you able to see?

Which is the right cable to buy with SA for the EG4 LL V2 communication? I see there are several types but none said compatible with EG4 batteries.

I just used the one the came with my batteries. Should look like this: https://signaturesolar.com/rs485-usb-battery-comm-cable-archive/
and got this to connect all the RJ45 cables together

Make sure you set the dip switches correctly

EG4 has relented:

Solar Assistant (Possibly) Voids Warranty on EG4 Inverters?

OK, so if wall worts are supposed to be isolated due to certification as mentioned here (click links to go to posts): https://diysolarforum.com/threads/solar-assistant-possibly-voids-warranty-on-eg4-inverters.68225/post-861857...
