| SG-Ready |
| With the PV optimizer AD PVO 6000 heat pumps can be signaled that enough PV surplus exists. |
| Thus, the heat pump can raise their storage or flow temperature and increase the personal consumption. |
| The optimizer is compatible with many SG-Ready (Smart Grid Ready) enabled heat pumps. The SG-Ready logo can be found on your heat pump. |
| The SG-ready interface is designed in in most cases as a contact input therefore, the overload relay of the PVO can be used easily as a signal for the temperature increase of the heat pump. |
| What is to be done at a SG-signal, it must be parameterized on the heat pump. |
| Through the three internal load relays, the heat pump can switch multiple states. It can be driven so several power levels. |
