OK, I'm sure this has been covered here many times but i can not find it. I hear several of you talking about the dangers or draw back of 12 Volt systems. Can you point me in the right direction to past posts that cover this. Is the problem the system or bad workmanship or poor planning? I will begin construction in 3 years and i'm a planner and list maker and like to have things all planned in advance. I'm looking at as many propane items as possible ( fridge, oven, hot water, lights. With a modest solar and battery. I have several generators as back up, and to use when i need the extra power. Wood heat. I agree there are so many 12 volt items available and the technologies are always changing so i am prepared to change as needed. Thanks for any info.
