Fount this in the changelog 551:

  • Adjusted some regulation constants for the standard MultPlus/Quattro’s (non Multiplus-II devices) to solve the issue that in some installations the requested power setpoint was not followed for no apparent reason.
  • Gridcodes for Spain, South-Africa, Denmark and New Zealand (NZS4777M) are made available for non Multplus-II devices (external IP protection required!!)

Some under the hood improvements.

Do not update unless you need the functionality or are addressing a problem.

This is a notice to let you know a later version is available, it is not an instruction to update it.

If a system is working fine, leave it.

Until I see an official announcement, I'm not updating.
There's a good chance the configuration tools need an update first.
Unsure if anybody has tested this yet.

Edit: I just tested it and the VEConfigure tools don't need updating.
My test system is now running v551, will be rolling this one out further and if I encounter irregularities I'll report back.
