Do you have a question about the SUNTWINS 3300TL and is the answer not in the manual?
Questions and answers
Hi I need to turn off the solar panel during cyclone weather, the instructions says 1. turn off Solar Main Switch in the Switchboard 2. turn off the DV 'PV Array Main Switch' (Left of inverter) - I can't seem to locate the main swtich
The Solar Main Switch for the JFY tech SUNTWINS 3300TL inverter is referred to as the "DC Switch" in the manual. It is located between the PV panels and the solar inverter. If the inverter has a model with the "-S" suffix, it includes an integrated DC switch on the PV input side. Additionally, the AC Switch is located between the AC Grid (Utility) and the solar inverter. These switches may consist of electrical breakers, fuses, and connecting terminals, and their installation should comply with local safety standards and be performed by a qualified technician.
