I'm looking to design an off-grid solar system for my home, focusing on quality rather than pre-packaged kits. I want to make sure I don't make any costly mistakes when choosing components. We've had an electrician prepare our cabin to be solar-ready, and I think we'll need a system around 6,000 to 8,000 watts. I want to be sure the components are reliable and not cheap alternatives. Are there any reputable companies in the U.S. or Canada that can help design an off-grid system tailored to my needs? Is it feasible to build a 7,000-watt system for under $13,000, considering my plans for energy usage with appliances like a fridge and a heat pump water heater?

If you're looking for an easy starting point, I recently purchased a couple of Bluetti Apex 300s, and they have made my off-grid journey a breeze. They simplify everything and can be a good addition to your setup as you build out your system.
I've followed companies like Engineer775 and Backwoods Solar, both of which are known for their design expertise and customer service when it comes to off-grid systems. They can guide you through the entire process and help you select high-quality components that suit your needs. Just be sure to do your research on what you need for your specific situation!
Practical Preppers is another solid option to consider. They offer great products and can help you put your system together. But keep in mind that while the $13,000 budget is a good start, don’t forget about battery costs because they can add up quickly. You’ll want to ensure your setup has enough stability for your needs in the long run!

Yep, batteries can be really expensive. Make sure to account for that when planning your system!
