1.What’s the specialty of this connector?
This connector is used for connecting three solar panels together in parallel. If you want to connect three positives together and three negatives together of three solar panels, then you can use one (male-female) pair of MC4 3 in 1 Y connector to connect it. Of course, this assumes that all solar panels are already using MC4 connectors.

2. Do we need to buy MC4 connector along with it for connecting cables?
Yes, if MC4 connectors are not already there in connecting cables, then you must purchase MC4 connectors separately.

3. Is the use of branch connector/y connector right according to IEC/IS standards?
If your current rating of MC4 and MC4 3 in 1 Y connectors is within limits then there is no problem.

4. What is the difference between MC4 & MC4 3 in 1 Y connector?
MC4 connector is used to connect positive cable to negative cable (for example connecting solar panels in series) while MC4 3 in 1 Y connector is used to connect to positive cables together (connecting solar panels in parallel).
