i just read a post on the other survival forum and read a post on how some guy made a homemade generator from a old 5 hp motor, a car battery and a 300 watt inverter.

Do you guys know if this could be done with a bank of batteries, solar panel and an inverter. Seems to me this would be quit and the way to go.

and the bank of batteries would hold power overnight i know people do this for RV's would it work for the house?


has anyone tried this?

They are called solar generators. I have been toying with the idea of building one to power my freezers in the garage. Some of the more sophisticated ones use a combination inverter/charger to keep the batteries topped off and ready for an emergency. I've seen homemade ones on CL.

I have heard of these, but from what I know, they are supposed to not be very efficent. (sp).

Might want to add a charge controller for the sake of the batteries.

I'm planning by next year to slowly and I mean slowly buying the equipment: solar panels, 30 amp charge controller, 120v plug in battery charger with float capability and AGM batteries. In regards to inventer, I have 3 - 400 watt running that I purchased from Home Depot at a clearance for less than $30 a piece. The inventers can also be plugged in a vehicle.

I only plan to run small wattage appliance for now. Since my backyard faces south I can get 10 hours of daylight non-summer months to charge the batteries and more than 10 hours during summer months.

Here are three sources for solar equipment that I've been looking at for a while.

Sure big battery bank and a big inverter along with a high amp charger.

Batteries have a shelf life. I read some where 5 years is good for many deep cycle type batteries needed to store power from a generator or from solar. Its the expensive element. I like the idea of a solar package that will run things during its peak time like air conditioning so there is no need for batteries but it will reduce my usage and keep me in the lower tiered rates. You can build solar panels pretty cheap if you look at eBay there are some good packages there, and then even better if you look at buying the elements separately. Its time consuming and you can buy panels and save a lot of time and the amount of money you'd spend will be insignificant to that time.

The size of your system is based on the load you need. I have a 5 kv system for my home with a generator and a bank of batteries. I'm still on the grid but the difference between usage and production leaves me with a electrical bill of about 200 dollars a year total.

With the throw of a switch, I'm off grid and my solar and battery bank powers the house unless it is a short cloudy day with high usage. We are a family of 4.

We heat with propane or wood and have a swamp cooler for the hot weather. We have energy efficient equipment in the home.

My standby generator is a continuous duty 15 kv unit that will charge the battery bank and the complete home with everything on.

Don't cut corners on your inverters as it will cost you in the long run.

A huge problem is getting your battery bank completely charged between cycles. If you don't get them charged up and cycled properly you will have very short battery life and low power output.
