Solar Project question/suggestion needed

(1/2) > >>

Greekman:
Well, i would like the members' viewpoint on what I intend to do.

For the time being I will be buying 4 3W solar panels to make a small appliances solar system (charging battery banks and a 7+Ah SLA battery)
Initially I was thinking of connecting the panels in such a way as to have either a 19V (4S) or a 5V (4P) output. Purpose was to skip the 19 to 5V converter.
(I have designed the wiring and switching method, and it is easily workable)

But now I wonder if it worths the trouble. What do you think?

I would suggest a 12 volt system to then power proper Lithium Ion chargers etc as you do not have the panel count for charging a 4S battery pack ,in my opinion.

Greekman:
no i meant regular power banks that are USB charged, not the DIY style

Carl:
Good luck.

kid_couteau:
This is just my thoughts on it.
Aim for at least 50 watts minimum for panels.

Solar is not as powerful as the youtube vids make it out to be.

I am planning on doing something similar as you and for a 7AH SLA battery if you want to charge it in a day go at least 50 watts.
