While the MaxBackFlow API message does set Grid Sell Back Power, setting it to Zero( 0 ) does NOT stop all sell back as shown in the data shot from a recent day from the utility company data page.
Is there any way to have true zero export except for when Forced Discharge periods are enabled?
The reason for this is because Export Pricing is based on the median price of the hours with export quantities. Without a way to have Zero-Export for all periods but during Forced Discharge periods our Export Pricing rate drops considerably because of all the included hours with super low export rate values. Some of those hours the Export Rate Pricing is $0.001( .1 cents per kWh )!
Off-Grid Mode does provide Zero-Export but cycling that daily will cycle the relay daily and I worry that will lead to a wear and failure issue over the years. And I've not yet figured out how to programatically swith Off-Grid Mode on and off.
