I just finished installing my 100W solar system. While I was waiting to receive all the components I went ahead and charged my battery the conventional way and did everything I needed to do to the 12v load side of my set up. I was able to run my 12v pump with the battery with no issues and the my multi meter showed that I still had 12.3 volts on my battery. I next installed my solar panel and also hooked up an inverter to use for charging batteries that go to my drill and other accessories. Everything is working fine and I added a transmitter that goes to my outdoor speakers.
My Wanderer 30A controller was showing a green light prior to hooking my solar panel to the controller. When I hooked up the solar panel to the controller the battery light turned red and the PV light has never come on. When I look in the manual that configuration says that the battery is "over-discharged". My volt meter shows 11.90V on the battery. I checked all connections and polarity several times but the lights stay the same. This was during the midafternoon of a very sunny day. How do I know if my panel is going to charge my battery?

The red light is showing your battery is to low......That's working as it should...... Unhook everything from your batteries and let your panel charge your batteries fully...See how long it takes? Then hook up one item at a time over several days..... But don't add another one until your sure you have enough panels.... I think you don't have enough panels for what your wanting to run....

as tat suggested, disconnect all loads and see if solar can recharge! the wander should get a flooded batt to 14.8v and keep it there for 2 hrs/daily How fast it gets to 14.8v depends on the sun, batt discharge and panel.
let's assume 100ah batt, 100 watt panel.
ya use 50ah/day but the 100 watt panel can return 20ah on a sunny day! Your battery won't last. ya use 20ah/day and the panel can recharge on a sunny day, what about cloudy days! Ya use 10ah/day, ya have some capacity for a few days of clouds and the panel might keep up!
Energy audit, how much ya gonna use daily to help determine what size batt/panel.
after disconnecting all loads, measure the voltage of batt and panel at the screw terminals of the controller and determine if over time the voltage is rising. Ya might want to charge 'conventional way' also.

Thanks for the input. I'll try your suggestions and see if that takes care of my problem.

Hey Rabird...you say the wander should get a flooded battery to 14.8v. My battery is a sealed battery. Should the wander get it to 14.8v as well?

Ok if I just read the manuals electrical specifications I can see all the information I need. Thanks for steering me in the right direction. I think I can work through this now but if not I'll be back asking for additional advice.
