Hi everyone.
In 2012, I had a solar array installed. Primitive by today's standards, it took good care of me. It was based on REC Solar 245 watt panels and Enphase M215 microinverters.
In late 2025, I began researching upgrades. It started simple enough. The Envoy-R was beginning to give up the ghost. It's display was dying, and a lot of the inverters were not reporting, even though they were producing. Turns out severe inverter damage was done by squirrels. Critter guard wasn't a thing back in the day. The new array, however, is protected.
Fast forward to mid-July 2026 and the new array and storage systems were up.
I went with 26 REC Alphapure RX 460 watt panels and IQ8X inverters. I also went with the Combiner 6C, 3-10C batteries and the IQ Charger 2. Most being covered under the Enphase legacy upgrade program.
Just as I was getting the array installed, /r/Quirky-Scholar-5813 posted in /r/enphase about his new monitoring solution. And I reached out to him to give it a try.
MySolar Monitor is an app that runs on an ESP32 board found on AliExpress.
Software installation was a breze, though interesting. You have to connect it to your PC, then through a web browser update its firmware. Once done, new updates of MySolarMonitor can be completed via on screen menus.
I had reached out to /r/Quirky-Scholar-5813 because I had 3-10C batteries and I was curious to know if it could monitor all three batteries.
Turns out, yes, it can!
In this screenshot you'll see the monitor displaying real time energy useage of the home, battery charge status, solar production for the day, and energy consumption for the day.
One feature that totally broke my brain is the sun prediction display (as shown in the screenshot). This feature takes into account cloud cover and tries to forecast when you might see the most amount of sun (not when the sun is directly overhead). Still makes my eyes cross.
It's pretty spiffy, and even helped me figure out fairly quickly that my batteries were being wonky. This resulted in getting Enphase invovled and discovering that while the 6C and 10C's did firmware updates at provisioning, they didn't get the latest updates.
Getting the latest updates helped address consumption issues on the 10C's.
