Hi everyone. I'm onto the next install and need to understand the actual functioning specifically of the Smartsolar charge controller xxx|yy - TR and the xxx|yy- MC4.
1. Why (Is the) difference between the TR and the MC4.
My supplier told me it's "safer" to use the TR than the MC4 option as there is less chance of a poor connection / they have seen failures on the MC4 due to high currents.
I would like an opinion on this.
This also then leads to the next question
2. Can one charge controller be used on multiple planes. I believe I do understand the concept of MPPT's. I am unsure of how the Victon Smartsolar xxx|yy - z deals with this
2a. Is there a difference between the MC4 and the TR other than actual connection / termination.
2b Would an MCT option be able to manage 3 different inputs eg one each of a North, East and West facing PV arrays.?
OR;
2c. Irrespective of the termination configuration, I would need a SEPARATE charge controller for each plane?
Should I not understand the concept I would value assistance.
Lastly,
3. My West and East facing arrays are smaller than the North facing array. Am I correct in understanding that I would be able to install smaller Smartsolar charge controllers for those 2 arrays.(Naturally taking into account for string voltages and Isc)
I will be installing 2 x 48|5000 Multiplus ||'s
Many thanks
