I have a customer with a Xantrex C12 charge controller with LVD controlling a 5A load. Their battery and PV are not large enough to run the load 24/7, and they don't need it to run at night. I am thinking about recommending a photocell to disconnect the load at dusk and turn it back on at dawn. They are not interested in upgrading the PV and battery (too costly).
Can anyone recommend a photosensor source, and maybe a model number? Other ideas welcomed... Jason Szumlanski Fafco Solar
