I want to operate my devices in the apartment with solar energy. Camera Batteries Phones Laptop and my Power Bank. I do not have any or minimal experience in electrical engineering, but I'm a logical thinking person with a crafty passion. And would like to build that from the ground up.
In the net I found only modules that cost a lot of money
My idea goes in the direction that I place a car battery on my terrace, the day and night is outside and is charged by the sun
Which I can tap at will to charge my batteries and the same
What would I need everything to implement that and what I wanted to pay attention to
You need the solar panels and the battery. That's clear. In addition, you need a charge controller. And those are not sooo expensive again.
certainly there are charge controllers for several 100 euro but in the performance class there are also devices already around the 40 euro the duchaus work and sufficient. It's not worth building for yourself!
and then the question arises, what do you want to do everything for devices exactly.
my tip: for cost reasons, I would think about giving up the inverter. Also for reasons of efficiency. Instead, you just get some USB charging plugs for the car for your small devices and for the laptop a matching power supply with a 12 volt input…
I have a yuasa np17-12I 12v, 17Ah she is several years old and was in the corner (should first enough for the test)
If I measured correctly he has a voltage at dcv / 20 6.98
What I would most like to recharge would be my power bank from Anchor with 20k mah over AC charges you in 8:47 hrs 17290mah
Also from techno line the bc 250 a delta u charger with single shaft monitoring for my AA-AAA's
My Cam Rechargeable Batteries from Nikon Lithium ion battery Pack with 7.2v 1230mAh
My two DC 12680 with 12.6v 6800mah for various equipment
There comes a lot together that I would like to load with the sun just not quite so much idea in the matter. Ch is a budding photographer and that's all part of the equipment
I hope I hb all the necessary information summarized
Yes, that's all, especially the batteries of the camera, small stuff. Since I would get the appropriate travel charger, which run on 12 volts and build a pure 12 volt system… That's enough…
What solar panel can I take or pay attention to which values
What am I packing between the battery and the USB hub
And what happens when the battery is fully charged by the sun
I would take one that fits a 12 volt charge controller. That would be about 20 volt open circuit voltage. And then a 12 volt battery, between the battery and cell, a 12 volt charge controller. This limits the charging voltage of the battery. For your 5 volt stories a cigarette lighter adapter. And for e.g. The travel charger for the camera or a power supply for a laptop, if desired, then just go directly from the 12 volt rail.
