For lithium batteries, there are many problems to deal with first. If it's an N-string, you need to buy an N-string protection board first (both electronic city and car products are available, but you can't buy it, so you need to get a broken notebook battery and remove the protection board). As for the protection plate current 5A, it should be enough for you. This is the first thing;

Second, the solar controller (electronic city, car products are sold). Generally, the solar controller is designed for lead-acid batteries, which is usually 12V or 24V. If you buy 12V, the number of strings of your lithium battery can only be three, but you can connect multiple strings, multiple strings and three strings, and the capacity of each string must be the same, so that the full charging voltage of the lithium battery is set to 13.8V/3=4.2V, 4.6. So that the lithium battery can be normally charged;

Third, the inverter (electronic city, automobile products are sold). 300W 500W, that should be enough. The price is only 200-300.

As for how to wire, it's actually very simple. In fact, you only need to prompt the protection board. I suggest you draw the wiring when you disassemble the notebook battery. The rest of the wiring is simpler, not a problem!
