Upgraded Cheap(est?) PWM Solar Charge Controller - 12v Solar Shed
This series of solar charge controllers are incredibly cheap, pretty efficient and quite functional. Previous versions have however been a bit light weight when it comes to current.
In this video I look at the latest version (CTK5S) setup for 6 or 12 volt sealed lead acid batteries and compare it to the previous versions (CTK3A).
