I just picked up a 200w adventurer system and installed this weekend. I am only getting 0.5v from my panels at the charge controller. I rechecked all connections and everything looks ok. Anyone have any ideas?

What's the weather like there? Do you have the + and - hooked up correctly from the panels?

Did you check it with a volt meter???

Open circuit voltage or when connected to the controller?

It was cloudy, and I did check with a quality meter.

Same, .5v and nothing to the batteries

me, disconnect at least one panel and measure the voltage across the + and the - (at the panel pigtails).
if .5v return defective panel.
do the same for the other panel

Anyone have any ideas? First check to make sure the correct polarity is on the charge controller. Sometimes people get confused with the adaptor kit being opposite connections. First step would be to use your meter to check the input PV terminals and make sure the polarity is correct. Otherwise the next step would be to check the panel voltage and make sure each panel is outputting the correct ISC and VOC ratings according to the spec sheet. -Renogy Team |

Hi,
I'm also have the same issue with my 20A rover Mttp controller. I've got one panel on the roof and getting about 19Volts with multimeter at the MC4 male/female connections, same voltage read at PV+ and PV- at the charge controller, however the controller says no voltage reading from the panels and the "crescent moon" icon still showing (indicating it thinks its night). I'm not getting an error code (E13) which would indicate polarity reversed. Is my charge controller defective?
Thanks for your help.
Ryan

The issue was reverse polarity. Issue has been rectified. The wiring can get confusing from going to positive male connector and negative female connector on panels to adaptor kits that have the reverse connections which sometimes has users switch them incorrectly at the controller PV input.

But that was in my first post which was the second post in this thread............. |

Just realized there were 2 requests on this. It was Mobile man cave. -Renogy Team |
