Offgrid: Solar Charge Controller Load output issues
My first post.
I have built a small off grid system to power LED lights during the night to provide some additional lighting on my street. I have the following:
100W standard poly solar panel
12V 26AH SEALED VOLT DEEP CYCLE RECHARGEABLE BATTERY
12V/24V PWM Solar Charge Controller 30A (also have a different brand 10A PWM charge controller as a spare)
14AWG running from my Solar panel to my charge controller
16AWG running from my charge controller to my battery
16AWG running from my charge controller load terminals to my load
My problem is from my charge controller to my load
At first, I had a 300W inverter running off the load, the inverter wont work and I thought 300W was too much so I got a 100W inverter. Same issue, load wont power the 100W inverter. I changed the charge controller and same results.
I tried to bypass the inverter altogether and got a 12v 12W DC LED bulb and hooked it to the load terminal - does not work. Same bulb direct to battery works, tried swapping the charge controller but still does no work.
During some trials and errors, I swapped the 16AWG wire from charge controller to battery with a much thinner wire (don't know the AWG, it was a laptop charger wire) and the inverter that was hooked to load terminal worked but I am suspecting my panel wont be able to charge my battery adequately with this wire). I don't want to hook my DC light directly to battery as I want the advantage of cut off when the voltage drops to protect my deep cycle battery + my charge controller has a dusk to dawn load feature. Plz advise on where I am going wrong.
Thank you all in advance.
