Review on Efficient 40A MPPT Solar Charge Controller Tracer 4210AN with Remote Meter and Temp Sensor Cable – Ideal for Gel, Sealed, Flooded, and Lithium Solar Battery Charging by Nick Tucker

I only give this 4 stars because the instructions were a bit lacking, it took me forever to find the system default password to change the settings. Other than that, it does what I need to be good at charging and maintaining my batteries. I definitely recommend the remote display. I installed my controller under a cabinet because it's a bit clunky and honestly I didn't want to look at it in my van. The remote display mounts beautifully and has a wealth of information that you can access to check the status of your batteries and set up the solar system
