DC coupled MPPT & Multiplus with Sonnenschein @Home Lithium managed battery

Hi,


Two question regarding the Sonnenschein @home lithium

  1. Will become an approved Victron battery?
  2. If used with the Color Control GX will it be able to have managed DC coupling like the BYD and Pylontech?

Hello Lock,

The Sonnenschein@Home lithium battery that looks like the unit below is able to be used right now. I have tested it myself and it is compatible, though not yet listed.

It works using DVCC, and this must be enabled.

Basic charging settings are:

Parameter Setting

Battery type Lithium

Charge curve Fixed

Absorption voltage 60.75 V

Float voltage 60.00 V

Absorption time 1 Hr

It uses the VE.Can to CAN-bus BMS type B Cable.

The GX device must be configured to CAN-bus BMS (500 kbits/s) CAN-profile.

All firmware must be the latest and up to date.

Shared Voltage Sense must be ENABLED

I will continue to follow this post up with more information and documentation.
