4 months ago Forgot to add HA entities to read:
Battery minimum SOC: sensor.solarsynk_{inverter sn}_battery_shutdown_cap (%)
Battery SOC: sensor.solarsynk_{inverter sn}_battery_soc (%)
Either:
Load power: sensor.solarsynk_{inverter sn}_load_power (kW), or
Load today: sensor.solarsynk_{inverter sn}_day_load_energy (i.e kWh)
Either:
Grid import power: sensor.solarsynk_{inverter sn}_grid_power (this is probably total import and export)
Grid export power:
Or:
Grid import today: sensor.solarsynk_{inverter sn}_day_grid_import (kWh) and
Grid export today: sensor.solarsynk_{inverter sn}_day_grid_export (kWh)

Hi fboundy
regards Mark
PV Opt can be updated to support additional models and brands of inverter. If you want to request this, please supply as much of the following information as possible:
Home Assistant Entities to Read
PV Opt reads data from a number of entities in Home Assistant. These will vary by inverter. Please document what your inverter provides. Examples are provided from the Solis Solax Modbus integration:
Inverter Control
PV Opt also needs to control your inverter. How this is done and what can be done varies hugely by brand, by model and by the integration you use with Home Assistant. Please provide as much detail under each heading. Examples are provided for the Solis inverter using the both the Solax Modbus Integration and the HA Core Modbus functionality. Please add your details below:
Examples
number.timed_charge_start_hour,number.timed_charge_start_minute,number.timed_charge_end_hour,number.timed_charge_start_minute. Then press 'button.solis_update_charge_discharge_times. Set the required current tonumber.solis_timed_charge_current.

What is the inverter brand?
Sunsynk
What is the inverter model?
ECCO 3.6kW hybrid inverter SYNK-3.6K-SG04LP1
What integration do you use in Home Assistant
Solarsynk2 add-on. There is another one Deye/Sunsynk Home Assistant add-on by kellerza but this requires a direct wired connection to the inverter
How do you enable forced charging?
Only done via a timer. Set a time slot x, tick grid time x to allow charging from grid, target SOC x (above current SOC) and power x. 6 slots are available
How do you enable forced discharging?
Only done via a timer. Set a time slot x, tick grid time x to allow charging from grid, target SOC x (below current SOC) and power x
Are forced charge and discharge controlled using Power or Current?
Power (W) and target SOC whichever is the smaller
Does your inverter support timed charging slots?
6 slots used for charge and discharge. Should be contiguous, sequential and cover the whole 24 hrs
Does your inverter support timed discharging slots?
Same timeslots as for charging but with a different target SOC
How do you enabled timed charge?
Set Use Timer = true To do this, populate helper inputtext.solarsynk{inverter serial no}_settings with json to update Sunsynk cloud api: {"peakAndVallery": "1"} (just possible this is a misspelling) Also required for slot x - Start time ("sellTime(x)": "02:00") Grid timer x ("time(x)on": true) Target SOC ("cap(x)": "80") if this is higher value than current SOC, batteries wil charge up to this value from the grid Power x ("sellTime(x)Pac": "3600") End time is defined implicitly by the start time of the next slot. An appdaemon process runs every 5 min to post the contents of this helper to the Sunsunk cloud api. This is not ideal because it's not online. Perhaps I could get the Solarsynk developer martinville to add a realtime update method
How do you enabled timed discharge?
As for charging but set target SOC low
Can you set a target SOC for a timed charge period?
Yes - this would be the usual manual method
Can you set a target SOC for a timed discharge period?
Yes
What modes does you inverter have and how are they controlled?
There are some settings which limit export to load or grid. Details to be confirmed but probably should be set manually
Any other useful information
