My question is do I need to add a voltage regulator to restrict the voltage in the above situation? Alternatively, is the only (or perhaps the best option) to tie it into a battery system. I would very much like to keep costs down and getting a charge controller, discharge control, etc. gets pretty expensive I fear.
Finally, battery maintenance aside, can you safely connect the pond pump to batteries and manually switch it on/off say for a night time party, and then trickle charge the batteries on ac separately?
I have been trying to educate myself online but technoterminology has fatigued me.
Any help is GREATLY appreciated.
