It covers all DC terminal screws, preventing accidental or inquisitive contact — especially valuable when the controller is installed in a general access area.
My MPPT controller lives in the garage at kid height, so this cover was a no-brainer. Fits the 100V 20A perfectly and all terminals are hidden once the lid is on. Installation took five minutes with the controller already wired.
Fits my SmartSolar MPPT 100/20 exactly as described. Had to reroute one wire slightly because the cover doesn't leave tons of room for oversized cable, but nothing a little patience couldn't fix. Safety is worth it.
Covers everything it should. No more exposed DC terminals.
It snaps on securely and does the job, no complaints about function. Just feels like paying sixteen bucks for a molded piece of plastic. Still cheaper than an ER visit though.
Honestly this should just be included with every MPPT unit. Live DC terminals with no cover is a lawsuit waiting to happen in any shared space. This one fits perfectly, looks clean, and doesn't interfere with the app or the LED indicators. Buy it with the controller and save yourself the worry.
