I just expanded by solar panels with 2 extra panels.
With the old setup, at around 12.30 PM the batteries are full and the renogy rover goes into FLOAT mode.
With the added panels the batteries will fill up earlier and rover will go into FLOAT mode earlier. Is it possible that the rover will destroy my batteries prematurely as it FLOATS almost all day now? Or does the MPPT controller lower the amperage sufficiently that it wont affect the batteries.

Once charged, Float 24/7 is how to maintain batteries. Float voltage/amp is just enough to keep em ready to go. Solar can't do that at night!!!
You are good to go.

No, the rover won't destroy your batteries by being in float mode all day long. Float mode is designed to MAINTAIN your battery without boiling off your battery's electrolyte or OVERcharging it.

Thank you for the information. What happens when the controller is in BOOST mode? is the battery almost full then?

most controllers have a timed boost often 2hrs, At the end of boost the battery is considered fully charged by some!
Boost is constant voltage charging, the controller holds the battery at say 14.4v and the current tapers over time.

"What happens when the controller is in BOOST mode? is the battery almost full then?"
Boost usually means that the battery is receiving the most it can from the panels, sort of the opposite of "full". No reason to worry, the charge controller exists to keep your batteries at optimum.

I'm getting two errors from Rover Charge Controller on two different systems if anyone can help translate the code for me?
1. E1 - "Battery over-discharged" 2. E3 - "Battery Under-Voltage"
Neither system will charge past 45-50%. Does this mean the batteries need replacing?

Is the draw on your system hooked to the batteries or the load side of the Rover CC??

What type of batteries? What panels are you using? Has it been working fine before this error? -Renogy Team
