Need help for project plans (Solar and Wind Generator)

AI Thread Summary
The discussion focuses on building an auto-sufficient energy station using solar and wind generators. Key inquiries include calculating voltage and current entering the charge controller without direct measurement, and the feasibility of connecting wind turbines and solar panels in parallel. Participants emphasize the importance of following charge controller manufacturer recommendations for connections and configurations. Additionally, they highlight that charge controllers protect batteries from overcharging and back current, with specific mention of the current requirements for charging a 12V battery. The conversation also touches on experiences with various battery types and their resilience to overcurrent.

Hi, I'm trying to build an auto-sufficient station, this is my "blueprint" for mounting everything together :

and I would like to know if it was possible to calculate the voltage and intensity entering the Charge Controller without measuring it, if connecting the WT and the SP in parallel is a good idea, and how much current intensity is needed to charge a 12V battery (even if it has to take many hours) any tip is appreciated ! ^^

Every charge controller I have owned came with recommendations for connections including serial/parallel in the manual.

I would follow the manufacturer's advice.

Okay, i'll wait till it's delivered to check that configuration then, thanks !

A bit vague. Charge controllers generally 1.) protect solar cells or wind generator from back current and 2.) prevent the battery from being damaged by overcharging. For my 1st 100W Solar Panel I had a rectifier and a relay that cut charging above 13.6 volts for a 12 volt LeadAcid battery. Twelve volts because RV stuff is 12 V. My panel was 21.6 V open circuit, but lower at its max current of 1 Amp. A L-A battery can absorb 10 Amps so overcurrent not an issue. Other battery chemistries are less forgiving. I once lived on a farm where the windmill charged an Edison battery, 50yrs old, which ran the electric water pump in the well. Edison is not the greatest battery but it survives abuse.

Yeah, the post you're trying to respond to is 3 years old. Thanks for trying to respond. :smile:
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
