Does the Rover 20amp MTTP controller provide protection so that I don't over discharge my battery? Paid $300 for a deep cycle, 100ah, 12v battery and would not want to destroy it by using it at night and discharging it below 70% capacity. Thank you. New to solar, just yesterday!

I don't believe it will... You will need to keep an eye on your voltage until your sure of what you can use and can't use...

Thank you for your reply. At what voltage do you suggest would be when I stop using the battery and let it recharge?

Until your sure of your draw and charge rate. I wouldn't let it get below 12.3 to be safe....... Be sure and let your battery get fully charged before you plug anything up... That's where many people make there first mistake........

does the rover have low voltage cutoff for the load terminals? can it be adjusted?

does the rover have low voltage cutoff for the load terminals? can it be adjusted? Good question, I was wondering that also. To piggyback, wondering what devices you all are plugging into the dc load terminals on the Rover 20a? |

Hell yes it does, and it can be adjusted (per the manual). you knew that! me, I run 5 watts of landscape lights (5 of them) from when the panel gets to 6v, for three hrs nightly, not the rover, a decent PWM controller. 7ah battery and 60 watt panel!! |

David, how about a trial run of your expected loads while monitoring batt voltage.
No big loads, 20A for 1.5hr is 30Ah or 30% of your battery.
small loads do add up if operated long term.
Can you use the rover to measure each load and estimate nightly usage to get an energy audit?
Under load batt v drops, the bigger the load the bigger the drop so determine 70% is a challenge
For a flooded batt at rest, 12.45v ~75%.
I'd find what represents 100% of you costly battery and make adjustments to the controller so that the batt get FULLY charged regularly.
I've extended the 2 hr default to 3 hrs for my tiny sealed battery.
