Description

Connect your SPH type Growatt Inverter from 485-3 port (see added picture) to Loxone ModBus extension. Check settings of 9600bps, 1 stop bit and NO parity. Default Growatt ModBus address is 1.

DO NOT USE or integrate the growatt meter in your loxone ModBus data link leave the meter exclusively for your inverter to prevent uncontrolled Re-booting of your inverter.

Set Export mode to ON (growatt manual ref 6.4.4 par 6) Set rs485 setting to VPP (growatt manual ref 6.4.4 par 7)

Set AC charge to Enable and add time frame 00:00 - 23:59 (growatt manual ref 6.4.4 par 3 or via https://server.growatt.com/login settings) If Ac Charge need to be used!! Set Grid First mode to Enable and add time frame 00:00 - 23:59 (via https://server.growatt.com/login settings) If return to grid need to be used!!

The added template: Provides full energy monitoring of you inverter and storage system

Will prevent PV power to the Grid when prices are negative (negative injection price) Charge your battery during low PV Power (clouded day) and night when energy prices are low Prevent battery discharge when energy prices are low, and discharge power when prices are high AC charging will be limited by Peak load manager if required Power to Grid export during night time whe energy prices are high

  2. Loxone File -> 0kB

    Open

    Markus Jezek

    Dear Lieven Lagrange, I am writing to report a significant issue with the file titled "Growatt SPH BH-UO + Growatt Ark.Loxone" in the Library.

    I have attempted to download the template, but the file I receive is 0 KB in size, indicating that the upload was corrupted or empty, and the file cannot be used or imported into Loxone Config.

    Could you please verify the entry and re-upload a complete, working version of the file to the library?

    Thank you very much for your time and effort in maintaining this entry. Best regards, Markus

  3. load priority switching does not work

    Open

    Sebastian Hoos

    Hello Lieven,

    First of all thank you for your work and publishing your template here. I was able to get the Modbus communication working, but switching between battery charging and discharging does not work. The inverter does not take the load priority. Do you have any idea what could be causing this?
