I have a Renogy Adventurer controller, (2)160 watt panels, and a brand new 115Ah flooded battery. When I connected the battery last evening, Adventurer showed 40% state of charge. Today at noon, with full sun, It's showing 93% charged, with 15 volts and 2.9 amps charging. I'm generally pleased, but was wondering if these numbers sound about right?
Also, I ordered a few extra items I didn't need - a set of (4)Renogy z-brackets, a pair of y-connectors, and a bag of (Hanson Rivet) well nuts (+/-30 left), 1/2 inch depth, for the aluminum skin on my RV roof. PM me if you could use them.

Hello, Yes that seems correct. The SOC% on this controller is based on the charging voltage and not the actual battery capacity. What this means is right before sunset you will see a high SOC and right after sunset you will see a much lower SOC but this SOC is not the actual state of charge of your battery bank. The best way to check you SOC is to read the voltage in the morning or at night 6 hours after the controller has stopped charging your battery bank and compare the voltage with a state of charge vs open circuit voltage chart. I have attached a link to one of these charts. www.trojanbattery.com/BatteryMaintenance/Testing.aspx

Thanks! This chart will be very helpful. I would have worried when I saw the SOC drop to 60% after sunset, had you not told me this.
But, of what use is this SOC reading?

Hello, While the controller is charging your battery bank you can use the SOC to check the battery percentage based on the battery charging voltage. In order to read the actual SOC I would recommend a battery monitor.

According to the description the Link10 should provide you with the actual battery capacity.

I just ordered one, I will let you know the results when I get it and figure it out If it works as shown, it should take a lot of the guess work out of the equation.

Guess I should update my last post, I went instead with the TriMetric Monitor, pretty impressive.
