ESS: Quattro (& CCGX)+ Batteries + Solar + Cheap overnight charge window.
I already have a system to try to limit the SoC overnight based on the next days PV forecast, however it doesn't always work and I end up feeding some PV back to the grid (which I want to avoid).
I would like to use a CCGX relay and the Generator start/stop control to turn on my electric immersion as a dump if the SoC gets too high during the day but also be able to run the immersion during the overnight charge window.
Appreciate feedback as to whether the following would work please.
I would use the 'normally closed' connectors on the relay such that when the the CCGX thinks the generator is running my relay connection is open.
Settings:
Using Battery SoC as the main switch:
Stop generator when Soc > 95%
Start generator when SoC <95%
I interpret this would mean the CCGX thinks the generator is running whenever the SoC < 95% (and my immersion would be disabled)
If I also set 'Do not run generator while AC1 in use', then the CCGX would disable the generator during the charge window (enabling the immersion)? If this doesn't work then I could define the quiet hours to match my overnight charge window and set conditions so that CCGX disables the generator through the quiet window?
