Hello everyone. I’m looking for advise on the best way to set my system up.
I’ll try and give as detailed description as possible about the system I am currently building for the well.
I’ll be using a 24v low flow rate pump (3GPM) to pump the water into a 275 gallon tank at the head of the well.
The well is 140’ with a static water level of 20’. It produces 30+ GPM
This is the pump
Using online voltage drop calculators I can set this pump at 70’ down the well using #10 wire with a allowable voltage drop of 3%.
I’ve got the renogy 40a charge controller, 4x renogy 100w solar panels and a couple of 12v lead acid deep cycle batteries
I’m going to set the solar panels up 2s2p to have a VOC of 48.6v and a Isc of 10.42a. The maximum draw of all the loads should be around 9-10 amps.
The loads will be, the pump, a 24v extractor fan, lights and a low voltage heat pad controlled by a thermostat for when it gets really cold.
This is the extractor fan
The tank has two electric float sensors (didn’t trust just one) that trigger a normally closed relay controlling the pump.
I only want the pump and the extractor fan to run when the solar panels are producing enough to power them without the aid of the battery.
I need the batteries to be fully charged and the heat pad needs to be able to come on at any time.
Can anyone help me with the best way to do this?
Thanks in advance.
