Review on 🔋 Renogy Adventurer 30A Negative Ground Flush Mount Charge Controller | LCD Display | Compatible with Sealed, Gel, Flooded, and Lithium Batteries | 12V/24V PWM by Marcelo Montalvo

The front button was broken on the first corner. Revain replaced him (yay). The replacement worked great for a year but now shows E01. He basically thinks there is no battery. I checked all the connections with a voltmeter and the problem seemed to be in the controller. (Panels give voltage. Battery is 12V. I removed all connections, left, then reconnected. It worked. It was evening. Next morning back at E01. Disconnect and left several times. Connect battery, it shows 12V and battery me hook up the solar panels and it goes back to E01 don't buy this unless you plan on replacing it too soon the problem is the connection I use 10-2 solid wire to connect the battery wire I have two wires twisted together for the negative and it seems to work a little better but still not perfect.On the positive side I bent back the solid wire so it's thicker and works a little better.I plan on changing the battery wire to stranded 10ga to see if that solves the problem Stay tuned in Latest update - Changed battery cable from solid to stranded th Worked first time Was excited Check next day t - EO1 - (you must be joking). Completely upset. The camper didn't move, the equalizers were down and stable. The wires must not be loosened. I didn't have time to deal with it, so I left. Came back the next day and everything works! Again the camper didn't move, nothing changed, just decided to look at the battery. I feel like I can't trust that. I sleep most of the time off grid and need solar power. I feel like I can't rely on this controller and will replace it. I do NOT recommend this product and would give it no stars if I could.
