panels, like batteries, produce differing voltages. the rule is that voltage (potential) wired in series, (neg open, pos-neg, pos open) produces voltage increase. such as 6v + 6v in series = 12 volts. if you have just created a 12v system from two 6v, you can then increase the amount of Amp hours available. you increase the capacity. you do this in whats called a parallel circuit by connecting pos+pos and neg+neg. so if you have a 12v system @ 50Ah + same = 12v @ 100Ah.
Good video as usual. It should be known that it’s not a good idea to pull deep cycle batteries down below 50% as this will dramatically shorten their lifespan. Also you shouldn’t mix battery types or even the same type batteries with others of very different ages. The whole bank will only be as strong as the weakest one.
great vids dan! i am currently waiting on my 2.58kw grid tie system w/out batt backup. any thoughts on hooking batteries up in the future? would hate to loose the power my panels generate during power outages due to hurricanes. i am currently buying 2 deep cycle marine batteries per month to keep it affordable.
Excellent instructional videos. Check out my 3 video series and let me know what you think. If everyone ran just three small panels, our need for oil would be greatly reduced.
thanks, you are right about all this . if i remove solar panel i get 12.6 volts . i thougt it had to hold what ever it was showing me when it was with full sunlight
example 13.5
When you have them at 13.5 v, remove the panel leads and see what the batteries are I would guess 12.5v is what they will be at. They should be around 12.5 with nothing attached. Most charger units will cut off before 14v to prevent overcharging. When your batteries are fully charged they will register 13.5-14v with the panels attached full sun and 12-12.7 when no panels or at night. How are they holding the load. Your system sounds normal. What you are seeing is full batteries + panel v.
hi Dan , please i need some help. i’m haveing all kinds of problems here . during the day the batteries will chrge to 13.5v and then in the afternoon they start to drop down and eventuatly by 6 pm they would reach 12.5 volts. is this normal ?
Do recommend if its safe to mix batteries in a battery bank? I have motomaster acid golf cart battery and was think of hookin in 2 gel batteries. Is that safe?
well i’m back from the us. we had a few days of full sun and when i came back my 4 batteries of 20 amps each where only at 12.4 volts when they should have been at about 14 volts i guess. so i returned my solar charger controller and not i have a 7 amp controller and we will see
is it possible to have like a giant battery by my house (Like a generator except holds energy) and use solar panels to charge it, and use the battery to power my house? lol
Thanks for the video, one question for you, when we start to use batteries do we need a device that stops charging them when they become fully charged if so what is it called?
Thanks again
so wiring in parrallel keeps the same voltage and you add the amps all together. Wiring in series you keep the amps the same but add the volts. My question is, when is it beneficial to wire it one way over the other – like what kind of power demand would do better with each?
k heres a question..check out a video entitled
“12 volt room II”, by a youtuber named “yuandrew”. In the video, he’s got 2 6volt batteries and speaks of their output to the inverter as 12v. But in your vid, you have lots of 12v batteries but don’t add the voltages together to determine the voltage output. Which is the correct way to calculate the voltage going out to the inverter?
so lets review. a 12v panel rated at 50w can produce a drain of about 4.16 amps. now if you are using an inverter to power 120v Ac you can only pull 1 10th or .416. its all relative.
i hope i really understand what ive just typed. at least thats been my thinking all this time. if its not exactly right… i apologize for being an idiot in advance.
in order for electricity to travel greater distances without much loss, it is a practice to increase the voltage. panels 200 ft from house (i think its something like thatf.. dont promise. do a google on it) you might increase the systems voltage to 24v and install a proper inverter that can handle it.

THANK YOU!!!!!!!

SEEP CYCLE 12 V?
I thought it was a deep cycle. well anyway I love your videos
February 23rd, 2009 at 3:23 pm
Also, how can I figure out how many amps a deep cycle battery can pump out?
February 23rd, 2009 at 3:23 pm
Can you please make a video on how to connect several solar panels together to pump out more juice? Thanks much, your videos are very useful.

February 23rd, 2009 at 3:23 pm
If the amp output is not WAY off also the voltage must be the same when hooking in parallel. do not mix 6v and 12 v in parallel.
Acid gel not the issue.
Amps/Volts. Amps important in Series if you have a peak load above the weakest link/battery.

your the man thank for your video joe williams it helped me va
February 23rd, 2009 at 3:23 pm
they are called charge controllers, they are pretty cheap. 25 bucks on ebay.

In the 9 minute of your video I learn more then 2 months worth of reading on the forums. Thanks you so much. I just brought my first solar panel kit
