Thermal control requires a separate controller. The STP125-70 can support surplus-triggered heat-pump switching through optional SMA Data Manager M (EDMM-20), a compatible meter and SG Ready appliance. Configure thresholds and the grid feed-in reference. The documented X3 example also needs a utility blocking device and break-contact relay; it encourages operation rather than modulating compressor speed. EDMM-20 manual applies from firmware 2.06.34.R. Local installation and utility requirements must be established for the Indian project. Source 1.Source 2.Source 3.Source 4.Source 5.
