Remote Control

[gt008]

Hi

Firstly thank you for a great integration. I have Solax X3 25kw Ultra Gen 5 plus 2x 23.2kwh batteries and I am using Predbat to plan the cycles with Octopus Agile import, fixed export (15p).

I can’t get my head around the remote-control functions and any help would be much much appreciated.

1. Is it still advised to use RemoteControl rather than the default control modes (Charger Use Mode)? I think I read somewhere that Solax Gen4/5 inverters no longer rely heavily upon EEPROMs, so RC no longer needed. I currently have PredBat working using the Charger Manual mode to force charge/discharge the batteries and then reverting to Self Use Mode when Predbat is Idle.
2. Am I right in saying that with Remote Power Control: Enabled Self Use that the this emulates the Charger Use Mode: Self Use, so can simply replace its use within automations ( or more specifically in PredBat)? Similarly that Charger Use Mode: Manual Mode to Force charge etc can be replaced by Remote Power Control: Enabled Power Control?

Thank you

Very usefull topic. Were do you findout info about PradBat? I have never heard about it. thx

PredBat is a HomeAssistant Addon that predicts the best (cheapest) battery usage (charge and discharge cycles) by modelling differing scenarios based on forecast solar production, published future grid import and export rates (Octopus Agile) and expected load (based on historical usage). It was originally written with GivEnergy inverters in mind but works with Solax with a little tweaking. However it does actively change the Charge Use mode of the inverter numerous times per day, thus my interest in using the remote control if the EEPROMs are getting cycled each time. Lots of info on GitHub and the Predbat Facebook group.

I am also wondering about this. I have X3 G4 Hybrid and tried to use RC in the past, however I did not find any affect on my system when triggering it so I must have been doing something wrong.
I currently use mostly Manual Mode - Force Charge or Force Discharge in my automations depending on situation, on a very sunny day I use Selfuse so I can also export. it works pretty well but I think I need to change things to more consider EEPROM and the battery cycles. Will check the PradBat though as I have never heard about it. Thanks

Hi Giles @gt008, I also started getting more insights into remotecontrol. Would you be so kind to share your latest predbat yaml.app file for the Solax inverter?
Best, Max
