Hi!
I have an H1-G2-WL, two EP6+ batteries and 4.32kWp worth of solar panels (2 strings of 8 panels). I'm controlling everything using HomeAssistant (modbus over TCP).
I can
1) prevent exporting: set the export power limit to 0
2) prevent the batteries from charging: set the battery charging current limit to 0
What I cannot do: when prices are so negative that I get paid to use grid power, force-charge my batteries from the grid without also using the solar power (it first uses solar and then adds grid power until the max battery charge limit).
Hence: is there a way to disable solar? Ideally via modbus, but a manual switch is also an option sometimes (when I'm home). I've tried setting the PV configuration in the inverter menu from "independent" to "undefined" (the other option was "parallel"), but that seemed to block the entire inverter: it went into a "Waiting" state, and rebooted when I switched it back to "independent" (lots of relay clicks and 60 seconds waiting time).
Thanks!
Sadly not, you can't prevent the charge, including solar without manually isolating the solar.

Is it possible this may be an upcoming feature?
In the installers advanced settings there is now a field for "segmented parameters" within mode scheduler that includes an item called "PV limited power"
