Solar Panel Problem?
Last year I installed a 120w solar panel and a SunSaver 20L controller to my Truck Camper. To monitor the system I installed a TRIMETRIC TM2025-RV / TM2025-A BATTERY MONITOR. And to read the vol...

Not bothering me...I'm just having fun! But I'd like to see the available current from the panel before it enters the controller.
I was just looking at AMAZON for these V/A meter and I saw a comment I thought was interesting:
1. The Red and Black wires go to the positive and negative power supply that will be used to power this meter, It cannot be the same power that you are going to measure. You might find that an old dc adapter from a calculator or something like that will serve the purpose of supplying power to the meter very well, Just make sure it is between 6 and 24vdc
2. Connect the shunt to the Negative Lead in between the power source (Batteries / Solar Panels / Whatever) and the load (Light bulb / Motor / Grid Tie Inverter / Whatever). The bolts on both ends of the the Shunt are intended to be used for these connections.
3. Connect the Yellow wire to the screw on the Source side of the shunt
4. Connect the White wire to the screw on the Load side of the shunt
5. Connect the Green wire to the positive wire coming from the load.
I AM running my black and red wires to the source I'm trying to measure. Maybe this is my problem. They should go directly to the battery just to power the V/A meter.
I'm going to try that tomorrow.
