Just lately my rover doesn’t seem to be charging the battery anymore. I measured today 10amps coming from the solar panel at the controller, but when I go through the menus it says .5 or maybe 1amp is going to the battery? I was expecting much closer to the rated 20amps or at least the 10amps im getting from the panels. The battery charge level is off too, I get 12.4ish at the terminals but it says 12.1-12.2 on the display. Previously it operated normally boosting the voltage etc. any ideas?

Specificity is important. What size system do you have? 10Amps coming in from the panel(s) and .5Amps charging the battery? The amps will diminish upon the battery/controller reaching float mode. What voltage are you seeing charging wise? What is the voltage before the MPPT charge controller starts charging the battery? -Renogy Team |

It’s a small setup just one 100w panel and one deep cell battery. I have all possible loads disconnected today and it’s sunny, I will get a measurement when I get home and see if the battery tops up the way it used to by the end of the day. The battery was reading 12.2v when I got the .5amp reading so it couldn’t or shouldn’t have been on float mode unless something is wrong.
Last night the battery read 12.1v after dark on the display and 12.3v on my multimeter at the controller terminals. Hopefully tonight it gets all the way up where it belongs, I will report back.

When you get a chance and to eliminate the issue being the panel (just in case). Utilize a multi-meter to get the VOC and ISC readings on the panel to make sure everything is functioning correctly. www.renogy.com/blog/how-to-troubleshoot-your-solar-panels/-Renogy Team |

So I was able to do more testing yesterday after a nice sunny day the display read 12.5-12.6 at night but my multimeter said 12.8-12.9 at the controller terminals. Today I witnessed on the display 5 amps to the battery in full sun and voltage up to 14v so it appears to be charging.
My question is this:
Is it a problem that my charge controller is readibg the voltage 0.2v lower than it really is? Is there some way I can reset the controller other than just unhooking it?

Awesome the Rover is a neat piece of hardware glad it should operate normally even if it’s slightly misreading the charge levels, good news. |
