Does the LinkZB/LinkPro curtail solar completely when the consumption price is negative?
The LinkZB and LinkPro have the ability to switch off solar in the inverter completely when Amber's general price for consuming power is negative.
In this scenario, the FiT price is negative as well as the consumption / buy price is negative.
The solar optimisations for Amber customers have a Zero Production Price setting in the automation. This is the price when the inverter should stop producing entirely. We set the inverter production to 0 if the Amber buy price is less than the Zero Production Price (which is currently set at -100 c/kWh).
