Hi, The 3 most common types of charge controllers are: 1) Simple on/off 2) pwm type 3) MPPT I'm currently working on a pwm type charge controller. The easiest is on/off, where the circuit sense panel voltage (optional) and battery voltage and decides whether the battery should be (...)
Im working on a home project using solar panels and a morningstar pwm charge controller. My goal is to somehow connect the charge controller to my arduino ethernet controller to monitor the voltage of the charge controller. The only problem is that looking (...)
You need to study the photovoltaic panel itself before the charge controller. Briefly: As current is drawn from the panel, the panel voltage drops, not necessarily in a linear fashion. So, there will be a point (voltage, current) at which the maximum power is transferred; where P=IV is a maximum. As the illumination changes, this point changes, so
Is there somebody that has the project of the battery charger published in the Elektor magazine with a BTI-CCS charge controller? I guess the charge controller code is CCS9620SL so don't read the article. Regards, Fernando

Dear Guys, I have developed a solar charge controller, using MPPT algo. It actually charges the battery in three stages : Stage 1 => Bulk charge using MPPT Stage 2 => Constant Voltage charging without MPPT Stage 3 => Trickling, when the battery is fully charged When i connect 12V battery to (...)
Hey. I have a quick question regarding this fast charge controller chip (MAX712/3). The data sheet says that it "supplies Battery's Load while charging". So this obviously means that when in fast charge mode, the loads power source comes frm the DC IN while the battery is being charged. However, what happens in trickle (...)

Have a look here a very good article Silicon Chip Online - Build A 12/24V 3-Stage Solar charge controller - PicAxe charger If you have lead acid then fully charged open circuit voltage will
for a safer side set the current to 1/3rd of the capacity of the battery....for ex: if the battery has 3AH capacity charge current shall be 1A....this is a case with lead acid.... voltage shall be set around 54V(2.25V * 24)....... i worked only with 12V batteries but i hope the same can apply here too.....
Friend i am going to design Solar charge controller for my Panel !!!!! i found this paper on here by Mr Arun!!! if any one of you have suggestion of charge controller using other UC or any other desgin please give your suggestion thanx regards :)
I want to know how to design MPPT solar charge controller. Can anyone help for this case?
Hello Everyone! I have started designing a solar charge controller to charge a 12V lead acid battery. Load for the battery will be a dc motor. What I have done till now is that I had designed a Buck - Boost Converter for a output of 14.5V. For the feedback circuit I had to use op amps for controlling the mosfet. In addition to these I (...)

I feel like doing up a circuit on charge controller charging a battery of 800mAh 3.7V 3.0Wh. I have no idea of how should i start.
I would say battery voltage,charge current and battery temperature, set a flag to sample the voltage/current every minute or every 5 minutes say All this depends on what you want to do with the data afterwards wizpic
Sir, can you help me make a solar charge controller 36V 40A with LCD display
The output of two 24V MPPT charge controller can be combined. I would not recommend to combine the input of the controllers. The best solution could be, connect half the number of solar panels to one charge controller and the remaining to other controller and combine the output to the battery.
If I connected 10 batteries with 10 solar charge controllers in different houses which are connected with common solar panel. the battery near to the solar panel is charging fast compared to other so now my concern is how to charge all batteries with equal energy distribution? You can connect a diode in series t

Hey i have built a small home made wind turbine i reckon it will produce maybe around 50-80 amps i have a battery bank Of 6 x 6 volt 305ah battery's all wired in series and parallel to make a masive 12v bank i would like to build a charge controller to protect them from over charging any help with a schematic Many Thanks Kizer
Hello everyone. I want to design a solar charge controller that can charge a lead acid battery of capacity 2 Ah, 12V, using a solar panel with 10 Wp capacity, 15V, and power an LED light of 5W rating when switched ON.

Hi Search this forum, Solar AND charge, there are a project in elektor,check their homepage. Perhaps you tried but there is always Google... /Cl
The specs of your PV panel suggest it is meant for a 12V system. Although you can connect it directly to your 6V battery, and it will charge the battery at a safe rate (.3 A is C/15 for a 4.5 AH capacity)... You should not allow it to overcharge the battery. In time there is risk that it will reduce the electrolyte level. A commercial (...)
Hi all, I am working on a simple system working to balance charge among four Li-ion cells in Matlab-Simulink. All the controller and Li-ion cell models are in Matlab-Simulink. I want to discharge four cells within an hour (3600 seconds), so I work around with the R,V, and I values so that the cells would take an hour to (...)

Sound on the frequency 1 kHz is normal. (Increase freq. and you will not hear sound) Capacitance of electrolyte doesn't matter. You have negative voltage on electrolyte. I can give you disadvantage of first circuit: 1. Stress for MOSFET and electrolytic capacitance. When you switch on transistor, capacitance impedance will be 0 Om at the
