Multiplus 2 - 48v set up

I am new to the domestic battery / inverter technology and just need to help on setting up my Multiplus 2.

  1. I have so far connected everything up and downloaded, then uploaded the ESS program to all me to schedule the times it charges.
  2. I want to check a few thinks.
  3. 1. The MP states - “blocked” when I don’t have the MK3 attached.
  4. 2. there is a constant low battery alarm. The batteries are new Plylontech us500 x 5 and 1 x us 3000. Some of the batteries have a red alarm light which I assume is something to do with their balance charge.
  • I’ve set a schedule to charge them, 00:30 for 4 hours and also a test time but that doesn’t seem to start them up. In the VE Config I said they were LIFOs with other BMS, should I have said VE Bus?

I’m going to switch the batteries on to see if they equalise. That’s about it for now.

Have you followed this doc to the letter?

The mk3 and the gx cannot be connected simultaneously.

The pylon operating manual also has specific instructions for mixing models.
