Hey everyone! Before I dive into buying gear for my solar setup, I want to ensure that my choices are solid and worth it. I'm open to suggestions for cheaper alternatives if they won't compromise quality. Here's what I'm considering:
- **Panel**: HIN-T435NF(BK) - starting with 1, but I might upgrade to 3 later if needed. Budget is around $160 per panel.
- **Charger Controller**: I'm looking at one of these options: either [this cheaper one](https://www.amazon.com/gp/product/B0719PGGBS) or [this one](https://www.amazon.com/POWLAND-Controller-Display-Regulator-Intelligent/dp/B0CDC9M1HJ). I'm leaning towards the cheaper option.
- **Inverter**: Considering [this 3000W inverter](https://www.amazon.com/WZRELB-3000W-Inverter-Outlets-RBP-300048/dp/B082XSR8JH) or [this one](https://www.amazon.com/gp/product/B0CCRRTWX6?smid=A34AVL2KAHCXQ8). I'll mostly be running a computer (~200-500W), with possible occasional use of A/C (20A) and microwave. I'm leaning towards the 4000W inverter.
- **Batteries**: Starting with my current 12V flooded 550CA batteries, but I'm also considering buying 4 of these [batteries](https://www.amazon.com/gp/product/B09L89LW3P?smid=A5KU5HDAPDC75) to achieve 48V for the inverter in the future.
Any feedback or alternatives? I appreciate it!

I admire your enthusiasm for solar energy! However, even three panels might not be sufficient for your needs. It sounds like you're aiming high with all those devices, so make sure you're checking the total energy consumption. Maybe scale down your initial plan or increase your panel count once you know more about your actual consumption. Getting it right from the start can save you headaches later on.
It sounds like you’ve done some homework, but just a heads up: your calculations seem a bit off. The 20A A/C unit will pull roughly 2200W, which means you'll need a lot more panel power to make it work consistently. An estimate shows that even with perfect conditions, a panel can only run that A/C for about an hour a day. Plus, battery efficiency losses will reduce that runtime significantly. You might want to reconsider your approach since your setup could be unbalanced for what you want to achieve.
Keep in mind that A/Cs have surge currents when they start. If you're pulling nearly 20A constantly, the inverter may not cope with those surges, which could be an issue for your setup.
Thanks for the feedback! I should clarify: I don't expect to run the A/C continuously—just need the ability to draw power in short bursts. Realistically, I'm focused on running my trailer's 12V system and charging my laptop, where I believe 400W of solar would suffice for my needs.
