I'm currently working on an off-grid solar setup and trying to decide between a complete kit, which includes everything like solar panels, a hybrid inverter/charger, MPPT, batteries, racking, and cables, versus piecing together the system myself. I've noticed that kits tend to be cheaper and come with matched voltages and battery management settings, along with a single warranty for the whole package. On the flip side, sourcing components myself would allow me to choose different brands and optimize for upgrades or specific needs, like cold-weather charging or more advanced system monitoring. For those who have gone the DIY route, did you face any compatibility issues? Knowing what you know now, would you still choose to DIY? That's my main concern!

Buying parts separately can be a smart move, especially if you find good deals on used components. I managed to get my panels from Facebook Marketplace for a steal compared to the prices from big retailers. Ultimately, it depends on how much time and effort you're willing to invest in sourcing and ensuring compatibility across components.
I'd definitely recommend going the DIY route! It really pushes you to learn how everything works together, which is invaluable when something goes wrong. Plus, building your own system can save you a lot of money compared to buying a pre-packaged kit. You can customize components to fit your needs and even create a more robust setup with better safety margins.
Totally agree! The process of learning about the system is a big part of the fun. Knowing each component means you can troubleshoot much easier down the line.
If you're looking for something under 5-6 kW, I’d say a complete kit is easier and more noise-friendly. If it's going inside your living space, noise is definitely a concern. But picking your components offers more control over the end result if you're willing to put in the time.
That's true! If you don’t mind a little background noise, DIY can be more rewarding. Just depends on your priorities!
That's a great tip about marketplace deals! After researching, I realized that doing your homework can lead to significant savings.
