Solar Charge Controller | What is it and How it works in a Solar Power System

Shop solar charge controllers at altE: https://www.altestore.com/store/Charge-Controllers/Solar-Charge-Controllers/c892/ Find out the basics of a solar charge controller, what it does, how it works, and how to select the correct size for an off grid solar power system. A charge controller is an important component in a battery based solar system and are not used in straight grid tie systems. The primary role is to manage charging the battery bank, prevent it from overcharging and many control the rate of the current and voltage at which it charges. We'll cover related topics such as Bulk Charging, Absorption, Equalization, Float, Low Voltage Disconnect, PWM and MPPT types of charge controllers.

I'm a newcomer to your site but really impressed with quality of your solar presentations so most general folks would be able to follow you, being in Brisbane, Australia and heavily involved in solar here, still learn a lot myself through your videos, many thanks

7:06 you said "Panel" instead of "Battery".

If a had a 12 volt battery and provide it 30 volt through a PWM charge controller, only 14 volt will reach the battery meanwhile the other 16 volt is wasted? Correct me if I'm wrong
-
what is the best inverters. i stay confused about best technology.

Now from all info I've picked up from your video's the system I was looking to buy is just not going to work or did I get lost in the mppt's and series /parallel . Can you tell me if this system will work? 8 Renogy 250 w 24 v panels (voc 30.37,vmp 30.20, vmp 8.29, isc 8.84) with a Midnite Classic 200 (79 amp output) with a 24v battery bank.From what I found it should be a 48v battery bank and that controller wont work. I'm confused

Hi Amy I have a smart harvest charge controller SCCM20-100 MPPT outback is it ok to wire up 3 x 100watt 12 volt panel in parallel to a 300 to 400 WH battery bank Many Thanks.Brian

Hi, Friend!
I need your help, please. As I told you I am using Minghe mppt charge controller and here in Israel now is very hot. The display is showing that the voltage of the two Batteries is 31volts nearly 32, is that normal? Can the voltage of one battery reach more than 15 volts and is there any danger? When I turn off the charge controller or at night the voltage goes down to 26.4 volts? What should I do? Can you explain to me what us constant current and what is constant voltage?
Thank You very much!
Best regards,
Emmanuel Távora Freire. -
Would it be possible to send you some photo of the charge controller working so you can tell me if it is really working in mppt mode? So you will see our Kalnoit( Electric Vehicle) Direct from Israel! Maybe by email or Whatsapp?
Thank You and best regards!

Thank You!

Hi, Mrs. Amy!
Wonderful your explanation!
Would it be possible for you to make a video explaining the MPT-7210 Minghe charge controller. I put one in my electric car. It seems that it's working fine but I would be much happy if you make a video explaining how it works and I would understand it better.
Thank You and have a nice day.
Best regards!

thank for info

thanks for this!!! now i know the difference between charge controllers!!! great help!! i will go to mppt charge controllers!!

+altE I must say this is a fantastic video and an eye opener for me. I currently use twelve 130W solar panels on a 12V inverter system. The solar panels are connected in 2 different arrays with each array connected to its own PWM solar controller and then to a 12V battery bank. The solar controllers are each 12/24V 60A . Now I want to change my inverter to a 24V inverter, which means I would upgrade my battery bank to 24V. Since my solar controllers can handle 24V, how do I connect my solar panels to the charge controler. Do I need to increase the number of charge controllers? How will the modification affect the charging rate of my batteries, will it charge them faster or slower?

+altE store thanks so much for the info,i would like to know what is the limit to the number of panels that i can connect in series for a 12v system so that i can have lots of charging current using an mppt.Can i have 114v into an mppt charging a 12v battery
-
Great video and presentation...I run the highest voltages possible on my arrays.

I really need your help here. I have a small solar panel that I would like to use just to keep a charge on one 12 volt battery. I will give you all the information from the back of the panel, and hopefully you'll be able to tell me what type of controller I will need in order to use the panel. Panel Information: Zamp Solar Panel: Model # ZS-M-20Cell Type: Monocrystalline Peak power (Pmax): 20 WattPower Tolerance Range: (%) -3% to +5% Open Circuit Voltage / Voc (V): 21,0 Max Power Voltage / VMP (V) 17.5 Short Circuit Current / ISC (A) 1.23 Maximum Power Current / IMP (A) 1.14 Maximum System Voltage (V) 600 V DC Dimension (MM) 345*470*25
Above Specification At Standard Test Conditions
(STC) 1000W/m* , cell temperature 25*C,am1.5
This is all of the information from the label on the panel. I'm sure this may help you to figure out what type of charge controller I need in order to put the solar panel to use. Thank you very much for your time, and all of your videos. I hope to learn from all of them. -
doesn't most panels these days have a blocking diode to prevent that reverse current flow at night?
Also are there solar setups that use this reverse current flow to melt ice build up the the panels? in this case that blocking diode would have to be removed? what charge controllers have this function?
can you talk about sometime the relationship between windturbine and charge controller like the midnite classic?
thanks
