Thanks, I'll have to look into how much effective light we are getting. So you're thinking that it's not enough... Is there a way to turn off the inverter so it's not having idle draw when not needed? I could also use a timer and reduce the hours of the lights vs. the photo eye I'm using now...
It’s a 110W panel and when measured is throwing out around 20.5V. It’s getting around 4 hours of direct sunlight a day and around 2-3 of indirect light.
This is what the specs are "Maximum no load current (at nominal input voltage) ....<0.30 ADC". All I'm doing is running 2 strands of christmas lights at night (controlled by a photo eye) and then no draw during the day. The battery should be able to be re-charged as the draw is very low, but...
So the inverter with no load is drawing enough power to drain the battery that quickly? What can I do to disconnect the inverter when not needed? Is there a DC photo eye I can put between the battery and inverter? I'm using a photo eye on the lights.
Also not sure if it has a standby mode is or...
I've been struggling for the past month to figure out why I can't keep a battery (12V 109AH Deep Cycle) charged with just running 2 strands of LED Christmas Lights (0.04W each). I'm using the 110 Watt kit from nature power with 300 W power inverter and 11A charge controller. I've tried other...
