Quattro compatibility with EG4-LL 48v batteries?

Hey everyone,

This is my first post in this forum, and I'm looking forward to being a part of this community. My question is:

Is the Victron Quattro compatible with EG4-LL (formerly gyll) 48v batteries?

The batteries are available through Signature Solar and have RJ45 ports. They are almost always seen paired with Growatt products.

Those batteries are unsupported since they are not on the battery compatibility list:

Approach the battery supplier for more information before using unsupported batteries.

I asked a similar question about a week ago. I’ve reached out to signature solar to see if they’ve done any testing with victron products.

As you can see if you click on the link, it s still not on the list.

But that doesn't mean that it isn't working.
It just means that it is not official supported and you have to ask the supplier/manufacturer if you have any problems.

confirmed. A "closed loop" connection between EG4-LL v2 & Victron is already possible.
