Enphase ac solar modules

[California760]

Hi folks i came across
Enphase ac solar modules Q-Cells 360w equipped with iq7+ micro inverter and interested in installing this modules paired with Enphase iq combiner box 4

Following questions
1.) what racking system can i use with this specific module mid clamps, end clamps,termination caps etc…..

2.) enphase iq combiner box 4
Does this box come included with the IQ gateway commission system box or does that have to be bought separately kinda confused on that?

3.) lastly how do you determine what size solar breaker you need for the main electrical panel

Thanks

Multiply your maximum output amps by 125% and round up.

So for example if you have 11 IQ7's on one branch and each microinverter output is 1.45 then it would go like this:

11x1.45a= 15.95a
15.95a x 1.25 = 19.9375a

So you'd need a 20 amp breaker for that circuit.

The manufacturer data sheets will have the maximum amp output for the microinverter model and will usually also have the maximum number of microinverters allowed per branch.
