An Uncomfortably Transparent Guide To Solar – Part 1: Overview
Ever since the BBB, I’ve been plotting on how to execute on making my own solar system, designed using UL 3741, complete with batteries! I’m looking forward to showing my entire process, as well as financial details, to provide context for others who are looking into getting or building their own solar.
This is part 1 of probably 4 or 5. Next up will be the design session! Subscribe so you don’t miss anything!

How To Curve Trace Through Rapid Shutdown
The general understanding in the solar industry is that it’s impossible to curve trace through module-level rapid shutdown devices, but with the right equipment, it’s 100% possible.
For this video, I used an APsystems RSD-Start kit for APsmart rapid shutdown devices (not in stock anywhere I could find), and a Fluke SMFT-1000, but you aren’t limited to using these tools to accomplish your task. Any curve tracer should work, as long as you use an appropriate transmitter box to turn on the RSDs first.
If you want to build your own (affiliate links ahoy), here’s a general shopping list:
- APsystems Transmitter-PLC with single core
- Capacitor
- Battery bank
- Box-attachable DC socket
- PVC box with DIN rail and cable glands
- An interesting option if you want box-mounted connectors. Be aware that these are probably not technically compatible with MC4, but it’ll work for this purpose.
- Tigo transmitter, if you want to make this for Tigo instead
If you want to make the box for a generically rated Sunspec system, I’d honestly just try sticking with the APsystems transmitter, it’ll probably work.

Smarter Shutdown from SMA (RE+ 2024)
Talked with TJ from SMA America about their upcoming 3-in-1 rapid shutdown device at RE+ this year!
The SMA Smart Shutdown is a 3-in-1 device (1 SSS can shut down 3 panels), and is RAIL-mounted, not panel mounted. Could be a pretty great option. It’s not string shutdown yet, but design-wise, the install process looks to be better than any other rapid shutdown device I’ve seen out there so far.
SMA says the SMA Smart Shutdown is coming in Q2 of 2025, along with their larger Sunny Boy Smart Energy and Home Storage products.
