Driving in Circles

The PT-100 Solar Charge Controller has now been replaced twice.

Yuma! No it’s not my favorite spot, but I’ve just made my fourth stop in Yuma in just over three months.

Solar System Issue

I first went to Yuma on 12/22 to talk with Starlight Solar Systems about installing a new system in the RV. I decided to go ahead with it, but the next available appointment wasn’t until 1/26. In the meantime I camped with the WINS (rvsingles.org) in Yuma, Parker and Quartzsite.

The second Yuma stop was for the big solar install on 1/26. The system was working perfectly and providing all the power I needed, but two weeks later the monitor/control panel inside the coach stopped working. I was still getting all the power I needed, but could no longer operate the system from inside and had no visibility to how well it was working (power production, battery charge levels, usage, etc.).

We spent a couple of weeks trying to diagnose this over the phone and email, then on 2/22 I went back to Yuma. They found that one of the components, the solar charge controller (Magnum PT-100, rated the best) was not talking to the inverter (they are ethernet connected) and blocking the inverter from talking to the remote. Starlight replaced the solar charge controller, everything worked fine and I headed back to Slab City.

Exactly four weeks later, on 3/21, while I was in Cottonwood, the same problem recurred. After another round of phone and email diagnosis I headed back to Yuma (from Flagstaff) on 4/4. Again, Starlight replaced the solar charge controller, everything is working fine. I’m on my way, just not real confident.
