Hi All,
In 2021, my family and I built a cabin on our hunting land. While discussing power options, it was decided that we should go off-grid solar as the utility company wanted over 20k to trench a line. I had no experience with solar power systems or really any electrical experience at that time (although I did take some circuits courses in college). While watching some of Will's videos on Youtube and reading through various resources on this forum, I was convinced that I could handle designing and installing my own solar system. I went through and did all the calculations regarding power needs and watt hours desired from the system taking into account what the total price would be. I asked various questions on this forum which involved troubleshooting the PV combiner box wiring, review of the schematic layout, and how the inverter/charger works in regards to the N-G bond. You all delivered and I wanted to share the progress on the install of my system. The install is not finished and I still have several steps to complete, but feel free to give critiques, offer advice, and ask questions.
System Components:
Inverter Charger - MPP Hybrid LV2424
Panels - 8 x 230w 2S4P configuration
Batteries - 3 x 24V 100ah SOK in parallel
PV Combiner Box - Watts247
Panel Specs:
Battery Specs:
Schematic:
I installed the panels on our cabin south facing roof. The angle of the roof is approximately the latitude of the area (42º), which worked out quite perfectly. I obtained some 3" galvanized conduit to run all the wires off local marketplace. The run of PV wires from roof to combiner box is round trip 50ft.
The wires exit the galvanized conduit and go through PVC conduit into the cabin. I still have wire clean-up and protection to perform here. I think ill used some sort of flexible tubing/conduit and or zip ties:
Here is the in-progress wired set up:
I still have yet to complete the inverter to sub panel connections and earthing of the solar portion, but decided to flip the switch on and see if everything was working correctly. I was able to get charging of the batteries in the early day time and a little cloudy. I considered that a success for my first build out.
Next steps are removal of the N-G bonding screw inside the inverter/charger, complete grounding/earthing, perform connections to the sub-panel, and build some sort of enclosure for safety of the components and people inside the cabin. Thoughts?
Thank you to this forum and its members for the support of my first solar system.
