Hello BYC members I am looking for advice on my harbor freight solar system.
I purchased and installed said system using their sealed battery as storage and plugged a 60 watt light bulb into a thermostat controlled plug which in turn is plugged into a 400 watt inverter. The light bulb is inside of a cement block just like I saw it done on u-tube. All this to keep the water font warm of course.
My problem is the bulb turns on as it should immediately when cold but does not stay on. No fuses are blown nor does the inverter trip. If I shut the inverter off and then back on the light bulb comes back on only to shut off a while later. The problem is not temperature related.
