Are there any Din Rail Ampere Meters that don’t require AC power to run? I currently have a shunt in my system that monitors the DC power coming in from my panels. I am about to upgrade my inverter to a smarter one and I will no longer need the shunt. But when looking around, I found some Din Rail ampere meters for AC and thought it would be nice to put something like that next to my DC circuit breaker near my panels. However, every one I have found appears to require AC power.
