How many panels can I connect to this controller?
This depends on the output characteristics of the panels, but their combined output voltage and current should not exceed the specifications of the controller - 150 V and 35 A.
As per the datasheet the maximum output current is 35 A regardless of the battery voltage, so the power of the photovoltaic panels depends on the battery voltage - 12 V: 500 W / 24 V: 1000 W / 36 V: 1500 W / 48 V: 2000 W.
