I have added an mc4 connectors and attached T-branch splitter connectors to the end of wires before mppt charger. I did that to split the power between mppt and a solar powerstation and for easy connect/disconnect. Most of the times my coach LiFePO4 batteries are fully charged, and so I thought it will be more useful if I redirect the unused solar power to my powerstation(solar generator).
It has been almost three months since the installation and all is working fine.Coach batteries and/or solar generator being charged. Today, I was tinkering with the wiring and I noticed that the end of positive wire coming down from the roof is hot to touch, and so as the MC4 and T-branch connector. I measured the current output as high as 25 amps, hovering 19- 22, over cast. I was surprised of that being all panels are flat on roof! I have total of up to useable 600 watts.
I used to have only one 200 watt solar panel and added two addl 200 watt panels and used the same 10 awg and gopower 30amp mppt.
Per the attached picture, A is the T-branch and B is the end of wire with MC4. Spots A and B are hot to touch like holding a fresh coffee out of a paper cup hot. Is that normal? I wish I have a temperature gun so I can really tell the exact temp.
