HYD 6000 EP - configurable battery charging from grid

[wixaw]

Hello,

I would like to be able to control my "HYD 6000 EP" in order to program the battery to charge from the grid overnight whenever I want.

Will it be possible to do this with your plugin in the future, or will I have to use RS232 ?

Thank you in advance.

Best regards.

Hi @wixaw, of course it should be possible. The only thing needed is to know the right registers in the modbus which controls it.

[wixaw]

so if I understood correctly I don't have modbus, because I don't have RS232 yet, and so I would like to be able to make the commands in IP

[davidrapan]

No no no, this integration also uses modbus but through solarman stick logger. It just provides the connection to the modbus of the inverter. 😉

[wixaw]

oh wow, would you have an idea to give me to tell me how to interact?
maybe a code that configures something on the inverter that could inspire me, because currently I see in your plugin only reading
Thank you very much 🙏

Re,
I don't know how to use your csv, I haven't ventured to tinker with pysolarmanv5

It's not about that library at all. The csv is just list of registers for you to try out...

For writing you have to use Modbus function Code 16.

That work ! Thanks you so much

i do 2 automation :

Start load:

alias: ifDemainRougeChargeBatterie

trigger:
  - platform: time
    at: "22:10:00"
condition:
  - condition: state
    entity_id: sensor.rte_tempo_prochaine_couleur
    attribute: attribution
    state: Rouge

  - action: solarman.write_multiple_holding_registers
    metadata: {}
    data:
      wait_for_attempts: 5
      device: 3c2eb32cdc5e79ef5f8a6bf1a47979b3
      register: 4368
      values: 1
  - action: notify.notify
    metadata: {}
    data:
      message: "EDFTempo: Lancement de la charge batterie"

Stop load

      values: 0
  - action: notify.notify
    metadata: {}
    data:
      message: "EDFTempo: Batterie pleine, arret de la charge"

If I find a better solution I will say it here

[davidrapan]

So 4368 turns on 1 and off 0 charging of the battery from the grid?

And which profile are you using btw?

[wixaw]

no not really, I based myself on the operation of the sofar2mqtt plugin
0 = automatic mode
1 = Time-of-use Mode

and I directly configured this mode on the inverter the recharge period (time, SOC, charge, effective date, day of the week)
We could do with these commands to configure everything with modbus:

Manual Sofar Solar :

Time-of-use Mode
If electricity is more expensive in high demand time (peak rate) & electricity is much cheaper in low demand time (off-peak rate). You can select an off-peak period to charge your battery. Outside the off-peakcharge period, inverter is working in Auto Mode. If your family normally go to work/school on weekends & stay at home on weekends, which means the home electricity consumption is much higher on weekends . Thus, you need to store some cheap electricity on weekends only. This is possible using our Time-of-use mode. In summer, if your PV system can produce more electricity than your homeelectricity consumption. Then you don’t need to set an off-peak charge period to charge your battery in summer at all. You can select an effective date (normallywinter) for Time-of-use mode in this case. Outside the effective date, inverter is working in Auto Mode. You can set multiple Time-of-use rules to meet your more complex requirement. Right now we support 4 rules maximum (rule 0/1/2/3)

great, i am trying this just now
