I have 3x80 watt panels and run lighting, fridge, TV, radio etc. I have no high current draw devices. Solar is the only way I charge my batteries. I have to be aware of what's on at all times, but wouldn't have it any other way. If I was to do anything I would upgrade my batteries to a larger Amp hour set to give me a greater reserve and thereby lower the cycle percentage, increasing their theoretical life expectancy. Batteries are only good for "X" number of full cycles, so the less they are discharged between recharges, percentage wise in cycles the theoretical life of the battery is at it's greatest. But if I was to upgrade the batteries then I'd want to upgrade the solar panels. So I'll stay where I am for now.
