    to get the most bang for your buck, stay with solar. Start with a basic system and pick a charge controller that will allow you to grow. That way you can add panels and batteries as your budget allows and you wont have to buy another controller. Nad is a tremendous resource in the area. I'm surprised he hasn't chimed in on the thread yet. Good luck.

    First thing to think about when getting a power set up for an SHTF event is how much power do you really need. There are so many products that don't require much power like LED lights, smart phones and anything that used AA batteries. In fact for light, a head lamp and several garden solar lights (Walmart sells them for a few buck each) will light a home. And a 40 watt system may be enough. But if you want to run a tv, toaster, or refrigerator you may need 100 times that amount. Most of your need can be better dealt with by other means other than using electricity.

    I think it all comes down to what you are preparing for. If you are only worried about a few days, you can keep food cold by keeping your refrigerator and freezer closed, and focus more on recharging your phone or computer or using energy efficient lights and small appliances. If you are worried about long term grid-down situations, a larger system will be needed to run appliances needed for comfort (refrigerator, freezer, hot water heater), but things like cell phones and the like will be of less importance.

    That 1800watt system that they're selling for $1900+ is a supreme ripoff. That ripoff prefab system can't even be upgraded for more power. Here is a system that you can put together in 10 minutes with 1200 watts (or more) of power for less than $350. The plans for this Battery Bank is at the link. Here is picture of the basic system. However you can set one up anyway you want according to your needs:
