I have 12 vdc panel, 12 vcd used motor cycle battery, and 12 vdc pump for my pond. Do I need the 12 vdc charge controller? Can I connect pump directly to battery and the battery directly to panel for charging?
The basic answer is yes, but your battery may not be correctly charged and protected if you have no charge controller.
HI I have a small solar powered pump for my pond with a back up battery for night . Battery is not great , would it be possible to connect the pump to a powerbank battery so it lasts the whole night or would this burn out the pump . thanks
If the new battery has the same voltage just a different Ah rating to extend the time, then there is no reason why the pump would not burn out.
Great Article, i was looking for those informations in german Language and found this…
I have two solar panel kits and pumps for my Koi pond. One for the fountain and one for the waterfall which also aerates the water. Can I connect some colored lights and batteries to one of the solar panels or do I need another solar panel. Thanks.
Hello Jenkins, you can, in theory, connect your lights to one of the solar panels, but the total power drawn by both the pump and lights may exceed the panels rating. Also during dull cloudy days the lights, which will only illuminate during the day, may take most of the solar panels power stopping the pump.
It would be better to have a separate panel just for the lights, a bigger panel for pump and lights (you will need to check the power ratings), and maybe a storage battery for the night, as this is when you need the lights the most.
