First, you're never going to get full nameplate capacity output out of any solar panel. Second, Chinese manufacturing is generations ahead of the US and anywhere else. Where do you think more than 80% of solar panel production happens?

What? You think the US is investing in solar panel manufacturing? We're actively doing the opposite.

Can you not put the batteries in parallel? Connecting batteries in parallel involves joining positive-to-positive and negative-to-negative terminals to increase total amp-hour (Ah) capacity and runtime, while keeping voltage consistent. This setup allows for longer-lasting power, such as doubling a 12V 100Ah system to 12V 200Ah by linking two batteries. It is critical to use identical batteries (same voltage, capacity, and age) to avoid premature failure and uneven charging.

I am interested on how do you guys utilize this set. The output is 12 volts and I saw people on this thread proposing buying additional iron phosphate battery to store the energy. How do I then connect it to my fridge, for instance? Do I need to buy an inverter and can I then plug it into the house outlet or just appliances individually?

Quote from SkillfulMask719 :
while I applaud your commitment to the goal, there is nothing green about solar energy. It is alternative energy at best. The carbon offset for these panels will never be achieved in their functional lifetime. They will produce power YES, they will never be green by the time you factor in the pollution created in their manufacturing. Until you find a solar panel plant being run by solar power and wind mills, its all a trade off which I am fine with. ultimately its about producing power WHERE you need it and WHEN you need it. living in hurricane alley (FLORIDA) I would accept lower output vs NO output after a storm kills the grid.

The fact that they're charging 14.5% sales tax (at least in SoCal) on the ORIGINAL price kinda kills this... Not sure what Aliexpress is smoking.

Ummm, it's cheap. It's Chinese. Don't get the controller wet. Don't expect 400w, more like 240w on a very sunny day. Have a safe journey.
China has the most advanced solar panel and battery technology in the world bud. You're delusional.

Quote from JohnathanC8680 :
https://youtu.be/KtQ9nt2ZeGM I learned a lot watching this
I learned that after understanding that video, and made sense in the video, that in Alabama they have a monopoly and if you attempted to install solar they will charge you more money than you will make off of it to force it where you have to buy money from them instead.

that's why apparently no one has solar here.

Various comments stating that it's chineasium, And I think that It's misplaced, It's not just that it's from China , it's that it's lying like online retails do. combined with the fact that it's made cheap and ready to break intentionally almost . I think that we should try to boycott companies until they stop lying .
