I have got a large number of Victron-Pylontech off-grid systems with Smartsolar MPPT installed. The inverters and MPPT are programmed as per the victron-pylontech instructions https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom . As these are off-grid installations with generator, I can not run ESS assistant.
I have realized that when solar power is available but the inverters call the generator because the load is too high, as soon as the inverters sync with the ac source, the inverters take all the charge and the MPPT DC charge goes to something neglectable. When the inverters stop syncing with the AC source the solar power raise again. Needless to say this is not desirable and client not happy with it.
I have seen others threads with similar problem but honestly a lot of ramblings and not really any clear solution.
The questions I think it is very simple. On an off-grid installation (with no ESS Assistant), How can I prioritize DC Solar over Generator?
