I want to connect a heater to my solar system, that may not always have 11Kw (50A) available. Will the unit cope if it does not have 50A?
Or can this the power setting be changed?
It is connected to the household electric box, and the input voltage is stable. Solar power supply is prone to voltage instability, so it is not recommended to be used on thermostats. Unstable voltage and current will affect product life.
