Mounting

I started work on the system yesterday by completing the DC cabling on the lean-to. I installed the branch connectors and then cut custom lengths of cable and terminated with the required MC4 connectors. I used large zip ties to tidy up the wiring. I then went back to the wiring inside the shed. here…

Before starting on the inverter (Victron SmartSolar 150/35) I connected the DC Cable to the rooftop isolator. This involved terminating the cable with male and female MC4 connectors. I used the correct crimp tool (Narva brand) with the #12 crimp insert. I then connected to the output of the rooftop isolator and temporarily cable tied…

Today I completed the install of the earth wire and the 6 panels. I started by adding the earth clamps to the rail and attaching the earth wire. It’s important to bond each rail to earth, and for there to be no joins in the earth wire. As I have four rails, I needed four…

Fathers day! What better day to install solar racking. Here are some progress shots. The first step was working out the spacing of the feet. My first attempt wasn’t so successful. I was using this spacing method: Foot – 5 empty Ridges – Foot – 4 empty Ridges – Repeat It became obvious using this…

We are in Week 8 of Covid lockdown and I wanted something to do on the weekends and as I haven’t done much on my power wall of late I figured adding more solar would be a good small project. My shed currently has 12 panels and the lean-to has enough room for 6 panels….

I have been working away at making the bus bars required to connect the new stacks. Here are some progress shots from various stages.

I started mounting the Victron 150/35 MPPT’s.
