I'm trying out a little project and have hit a brick wall. I'm trying to design a 12v system to circulate some water over 200 metres. I have a 12v water pump which draws 9 amps. It is powered by a 100Ah deep cycle battery. My dilema is how to recharge the battery. I'm told that i need a 3 step charger for this type of battery. I only have a 12/24v 30A car/truck charger. Is it possible to use a solar controller but instead of connecting to solar panels, connect it to the 12/24v battery charger?
I'm assuming then that the 12/24v battery charger will supply more than enough current to the solar controller, which will then in turn regulate the charge to my deep cycle battery. The pump will run for about 6hrs a day. So i have about 18 hrs to recharge the battery.
Is this possible? Or am i completely of track?
Any assistance would be greatly appreciated.
