Hello,
I have similiar question. I want to integrate hvac system with solar inverter. Is it possible, that in future sun2000 will have digital output controlled by instant power or amount of sending to grid energy?
In Fronius inverters, there is four digital output, which can be connect to relay and control any device. Conditions to activate output can be set by web user interface.
i.e. if active power > 5 kW turn on output 1
or
generating more than 3 kW to grid turn on output 2 (need smart meter of course)
In Huawei i found only digital inputs, no outputs. Is it possible add this function only by software update? For some reasons I prefer to install Sun2000 rather than Fronius.
I know I can achieve this by using Modbus or using FusionSolar api but such solution needs additionally control device and is dependend on external system, which cause is less reliable.
