1 95W panel as part of a GoPower system - PWM controller charging 2 225 amp/hr 6V batteries. Trailer has all LED lighting, low power furnace (1.8 amps) Maxx Fan, 1000w Xantrex ProWatt SW inverter.
I can boondock until I run out of water - 2 weeks so far, making a pot of coffee each morning (60 amps for 6 minutes), a couple of hours on a 9 amp @12V laptop, running the furnace around 45 minutes, a cell phone amp & router drawing 2 amps, and various camera & phone chargers. The system is back to 100% by the end of the day, usually before noon.
