Hi, we’re running a 12v fridge off 3 leisure batteries connected to solar power. Though the fridge worked fine for the first week on solar charge, it’s now cutting out whenever we plug it in. It starts for 5 sec then shows error message ‘Not enough voltage’ - however, as per the manual the...
Hello,
I am building Solar Guitar™ prototype, an eco-friendly, self-sustained musical instrument solely powered by the Sun.
10-15 watt, 2 speaker guitar amplifier with preamp/reverb/chorus/delay/overdrive will be installed into the guitar’s body.
Looking for a creative specialist to build this...
I've been gathering electronics from CRT's to computer modems, to LCD displays, wifi extenders and much more. I'd like to mail products I have to people who have junk stuff lying around such as, the cheap open circuit boards that serve purposes and to anyone who can give me a schematic to build...
Hey everyone, I'm working on a little project but circuit design isn't my area of expertise. I want to build a little electric fence to put around some potted plants and keep the squirrels away. There isn't an electrical outlet nearby, so I want to rely on solar power.
I bought an electric fly...
Hi,
I'm currently in the process of converting a sailing vessel to electric propulsion and need some assistance/ideas on generating maximum power for battery charging.
Details of the system
Motor - 48v 20kw motor
Battery - 32 x 400ah 3.2v LiFeP04 cells - Connected in series/parallel for 51.2v...
OK, it has been few months now since i installed my solar system. It is a small one but i want to extract every ounce of juice i could get from my solar pv's. I am already aware that the mppt charge controller can do it's wonders. Currently using a pwm one and the only i time i get full...
Hello
I have got one last confusion about charge controllers doesn't matter whether it is pwm or mppt.
Thing is i have seen many CC with variety of output amps on 12v and 24v with different manufacturers... But they are all different..
Which number in a charge controller defines that how many...
Hello
Soon I am finally thinking of buying solar system.
Not that big only 600w max.
So I was thinking of buying 4x 150w panels.
I am confused how to connect them.
Series or parallel... I have researched a lot on this topic but in the end I always got confused.
The next thing is charge...
Hello
I don't know much about solar stuff.. I have been researching a lot lately on the topic. I stumbled upon this solar inverter on ebay
**broken link removed**
**broken link removed**
It has a pwm charge controller but what interests me is that with only 40A current 750W panals can be...
Hello
I need to clear some doubts about solar power.. I will write down my theory please correct them if i am wrong.
I must tell you that i have absolutely no knowledge of solar power system. I have tried google but couldn't understand how solar panals are calculated and how many batteries and...
Hello everyone. I am doing a project in which I use a buck converter to convert high vtg to low vtg.
Actually the input to the buck converter is from a solar panel which puts out 560 mA constant current and 34 V.
And output is a 12V lead acid battery. The N- Channel mosfet is used at high side...
