Exporting batteries to grid at peak tariff time
I have a new PV system with Sunsynk inverter and two batteries and am currently running the house from the PV and exporting once the batteries are full. In the winter I don’t expect to be able to just use PV, so to take advantage of a variable tariff I want to charge the batteries from the grid at night, and export from the batteries during the evening at peak rate. I can see from sunsynk.net/plants/setting how to charge the batteries at night, but I don’t understand how to set a time to export. E.g. 2am to 4am charge from grid to 100%, 4am to 4pm run house from PV and batteries, exporting any excess PV over 100% to the grid, 4pm to 7pm export to grid down to 25%, keeping 25% for running my house until 2am.
How do I configure this using the sunsynk.net/plants/setting web interface? I’ve found some similar threads in the forum, but none that specify exactly what settings of “Selling First / Zero-Export + Limit To Load Only / Limited to Home” or “Solar Export” or “Priority Batt / Priority Load”, when to tick or untick the timers,
In system mode, you need to change work mode to selling first, that will then cause inverter to start exporting in accordance with timer settings (power and SoC).
