You have a solid plan from the sound of it. You are far ahead of most. But we Prepper’s know about 95% of the population aren’t prepared. Heck my neighbors, who are ex military, are out running around in their camper! Which frankly shocks me.
Did you buy a special freezer or just an energy efficient one? Also, can you share what panels and inverter you decided on? There are so darn many.
The current freezer is an older non-efficient version (those things run forever). Looking at picking up a energy efficient this weekend and will put in my garage.
As far as Solar Panels, I went with 6 HQST 100 Watt Polycrystalline panels for a start giving me 600 watt system (with ability to grow later). Have a SolarEpic MPPT 40 AMP charge controller. I will be running the system on 24v so I can use smaller wiring. The initial inverter is a KRXNY 2000 watt 24 volt inverter.
Most of this is just a starting system. I went with a more expensive charge controller that will allow me to add additional panels and batteries once I get the system working and can prove it's value. The inverter is really just a starting point. I expect to upgrade that in the future once I have a better understanding where I am going with this. I have NO plans to ever grow this to be able to power 240V appliances. It is designed to simply supplement my existing power. I will add several new outlet in the walls and wire that back to the solar breakers. NEVER touching the existing grid system. If the system ever gets bigger than that level, then it would be beyond my skills and I would have to bring in professional electricians. I just want to keep it simple.
