How to control inverter as if in "self-consumption" or "feed-in priority" without setting eeprom (for dummies)

[jprates]

Hi all,

I've a quite complex energy management system in place using this integration with my inverters, EV wallboxes, and general appliances.

All is working quite well, but it requires the eeprom registers to be set along the day as the grid buy and sell price varies, changing from self-consumption to feed-in priority and back whenever needed, setting the export limit, charge/discharge periods, etc.

I already did some math and at the rate I'm changing the eeprom it won't be a problem for many years unless they are defective.
Despite this math telling me "you're fine", I'd prefer to start using any of the other methods made available by the current integration

I have searched the github, the docs, the FAQ, and I did not see any "starter's guide" or "remote control for dummies" kind of paper.

Where do you guys, who are more experienced in this integration recommend someone like me to start reading/learning from?

Thanks in advance,

What inverter are you using?

Solax X3-Hybrid
Firmware: DSP 1.59 ARM 1.57-1.15
Hardware: Gen4

I'd use the Mode 8 remote control interface then. There is some documentation here: https://homeassistant-solax-modbus.readthedocs.io/en/latest/solax-mode8-modbus-power-control/

There's an example script you can add to home assistant ("Example script for simple Mode 8 operations with Predbat") which provides a simple way of:

• Force Charging the battery at a specific rate
• Force Discharging at specific rate
• Freeze Charging which prevents the battery discharging but still allows it to charge from solar if there is any excess.
• Freeze Discharge which prevents the battery charging, with any available PV going to the house/grid.

There are various other modes available (e.g. for negative injection pricing) but the script gives a simple way of getting started.

Thanks, I'll have a look.

I also found the move from writing to eeprom to using mode 8 remote control quite intimidating. However I found AI particularly helpful in explaining this mode of control and also how to implement it. Personally I used Gemini but they all seemed quite clued up!
