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 buy (general) price for consuming power is negative.
In this scenario, the sell (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 at which 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).
Most hybrid inverters cannot fully curtail solar generation to zero while a battery is charging. In this state, the battery prioritises using all available solar power, drawing only the remaining balance from the grid to meet its charging requirements.
