creates the interface to the 'SG Ready' standard. This means that every user can benefit from future smart grid tariff models. The 'SG Ready' standard was defined by the German Heat Pump Association (BWP) e. V. in order to be able to connect heat pumps to the smart grid. Almost all STIEBEL ELTRON heat pumps are therefore able to benefit from future smart grid tariff models. If a PV system is present, the ISG plus can also be used to optimize self-consumption. For this purpose, the compatible inverter sends the ISG plus a signal when the self-produced, inexpensive PV electricity is available. Easy operation of the heat pump system, local homepage for the device, high data security, influence of the heat pump operating behavior via two inputs.
