Hi all,
Complete solar newbie setting up first system. We have 4 100 watt panels, wanderer cc, and 2 6v 225AH batteries. Right now we have the cc hooked up to just one panel as I'm still waiting on the mf4 connecters to arrive.
Upon first setting up, both pv light and battery light were solid green. With a 500w inverter- we had ax power immediately- Charging electronics and powering lights. We turned the inverter off overnight and this morning the pv light is flashing fast (seems more fast than slow) and a solid green battery light. I checked voltage on the connected panel and it was at 12.4v- filtered forest winter morning sun. Disconnected panels and pv light still flashing. Any ideas?
Other random questions to entertain:
How do we know panels are charging batteries?
Are 2 6v 225AH batteries in series a good match for 400watts?
Is the wanderer an appropriate cc for 400watts?
What does the solid green pv light mean?
Yes- I am really that new at this :-) thank you!

Not sure about your specific controller but on my Rover 40 the panel led flashes pretty fast when it's Float Charging the batteries.

Yep if your batteries are fully charged it will be floating and flashing fast. With 4 100w panels you will charge the two batteries quick... What are your plans to run off of your system?
12.7 is fully charged with no draw or charging.. Be sure and buy a Hydrometer, it is your friend...

pv and batt both slow flashing is float see page 12 www.renogy.com/template/files/Manuals/Renogy-Wanderer-30A-PWM-Solar-Charge-Controller-Manual.pdfI'd disconnect the panels, then the controller and reconnect batt then panels, and hope straightens itself out. Keep probing either the input PV or batt terminal when the sun is shining, the controller will let max solar power charge the battery up till batt v is 14.8v (flooded), (temp corrected, higher in the cold and lower in heat), Then the controller limits solar power while maintaining 14.8v for 2 hrs and then goes to float of 13.2v (flooded). I would not use a inverter via the 'load' terminals of the controller. |

What does the solid green pv light mean? Yes- I am really that new at this :-) thank you! this may have already been answered...I have a Wanderer as well and page-12 of the manual has the LED code...  Take a look at the table and see if it makes any sense based on what you had connected/disconnected and conditions. For my system, when everything is connected under 'normal' circumstances and I am using the battery; PV Indicator = slow flashing Battery Indicator = Solid My camper-trailer is currently sitting in the driveway with solar panel connected and without any battery use for several days; PV Indicator = slow flashing Battery Indicator = slow flashing When I disconnect the solar panel but still have the CC connected to the battery; PV Indicator = off Battery Indicator = Solid I would recommend double checking the polarity of the solar panel wiring to the charge controller. It is easy to inadvertently mix up the polarity at MC-4 connectors if you don't label them. Or you have a defective CC... |
