Hi there. I have a 12 volt panel connected to a charge controller which I got from eBay just to power a light in the shed and have had the system working fine until a few days ago when it stopped charging and really need advice to track down the issue.
The panel has the diode in line and like this one: http://www.ebay.co.uk/itm/20w-Solar-...UAAOSwHnFVmR5E
which is outputting 17 volts but when connecting with to a controller unit with the below features it is not charging.
Automatically manage the working of solar panel and battery in solar system.
Overloading & short-circuit protection.
Reverse diacharging & reverse-polarity protection.
Under-voltage and over-charging protection.
Protection from lightning strike.
Prolong the battery life cycle and keep the load work well.
Easy to set up and operate.
Suitable for small solar energy system.
Specification:
Color: Black
Rated voltage: 12V or 24V
Rated charging current: 10A
Rated load current: 10A
Voltage of stop power supply: *10.8V or 21.6V
Voltage of resume power supply: *11.8V or 23.6V
Voltage of stop charging: *14V or 28V
Working temperature: -20 ~ +60℃
temperature coefficient of voltage stop charge: -3mV / ℃ / cell
Item size: 10.2 * 9.5 * 3.8cm / 4 * 3.7 * 1.5in
Item weight: 132g / 4.7oz
Package size: 11.5 * 10 * 4cm / 4.5 * 3.9 * 1.6in
Package weight: 136g / 4.8oz
There is no output to the load +/- studs as a result.
Do I need to replace the diodes? Is it outputting too high a voltage ?
Appreciate advice. Thanks Darin
