Not sure if this is a dumb question or not, but should a solar regulator be installed nearer to the battery or nearer to the solar panel, or does it make little difference? Hope one of you blokes can throw some light on this for me. Cheers.

Solar regulators regulate the voltage and current flow from the panels to the battery...therefore in theory the closer to the battery the more accurate the regulators assessment and controlling
Having said that..... whether or not the controller is too far from the battery is relevant to the size cable used...if cable is too small you may some issues with volt drop and innaccuracies in battery management / regulation............correct size cable will overcome this........regardless of position
.....horses for courses as they say...rule of thumb is nearest the battery but not set in stone if the system is designed correctly
just visualise the water and hose pipe diameter example........the longer the hose and the smaller the diameter the less flow at the other end........pipe size = cable size. water = volts. pressure = current (amps)
