Hi,
I am not too good with circuitry and electronics. I want to Build a Solar Charger for my 12V Lead Acid battery (8Amp). i have two solar panel of 5 Volt 1.25W 250mA. I also have a 40Amp Charge controller. Controller doesn't seam to charge the battery. The Battery just kept draining by the controller even without load. i tried adding capacitors to the Solar panel terminals to boost the panel volt inorder to charge the batteries but to no success. i connected the panel to a boost converter, the boost converter did not power on. the peak panel volt without load is 13V. and the the boost converter only requires 3V to power up and boost up to 35 volt. my question is, how can i make the boost converter power on with the solar panel volt? would appreciate a circuitry explanation or low cost solution. thanks.
