PWM charge controllers behave the way you just described when you connect a 24v panel to a 12v battery.
They drag the voltage down to battery voltage so you end up using half the panel capacity. An mppt would use the panel voltage and adjust current accordingly.
But it should still charge
1. You should be able to adjust the charge settings in the cc 2. You can get an MPPT cc 3. You can get 12v (18v) panels
I'd have added upgrading your battery bank to 24v but I've not had a good experience with pwm and 24v.
Hollawayn05: Thanks so much I just got a meter, the cable reads 33v when removed from the cc, but reads 12.5v after inserting into the cc, I have climbed the roof top check the joint, theres no acrk or so but I haave retwisted and still the cc dint display the real volt I got from the pv
islamics: Hello House, Be like I don be victim of lead acid not the best oooo. Is it possible to wake/charge dead lead acid battery? My ba3 drained completely, so I took it to where I can charge it but was told it won't charge as the thing no get even small charge.
My small souer 10a charger has woken car battery from 0v more than once.
Vahyela: Greetings to the Gurus... I have a centurion automatic gate which I always find it difficult to use due to lack of Electricity(we all know what light has become in Nigeria now) please I want to know the material needed to use Solar. I.e. The capacity of the Panel e.t.c The battery is 12V 7.2Ah I already have a solar controller.
What is the motor power in watts? can you find it? Charging a 7.2AH battery any small 12v panel below 200W would comfortably do that
From their site their solar kit recommends a 40W panel Solar kit includes: 1 x 12V Operator (comes standard with Foundation Plate, Controller, 1.8A SM Charger, 2 x 4 Button NOVA Transmitters, 4 x 1m modules of CP20N4 / Stagnoli Gear Rack) 1 x 33Ah Battery 1 x Battery Enclosure 1 x 40W Solar Panel 1 x Solar Panel Bracket 1 x Solar Regulator 1 x Solar Panel Connector Kit https://gateandfencehardware.com.au/product/d5-centurion-centsys-evo-sliding-gate-motor/
FireTheSun: Good to hear, though l have my doubts about the authenticity of that information, without any link/Reference to the manufacturer to back it up.
If that is the case, what is then responsible for the high Cost of Panels right now? Excessive Profiteering? High Input Costs? (Especially Power!)
FireTheSun: What does it take to produce Solar Panels in Nigeria? Dont we produce Batteries (Berec Batteries, Exide Batteries) in Nigeria, in the 70s/80's?
These are the two major expense in Solar Setup, if we set our priorities right and stop enriching China, every house can have a Solar Panel and Batteries for backup at night.
Please forgive my rant, e just dey vex me at times.
Looooooool has any government ever cared about intense enjoyment?
I'm only saying what I've observed over the years.
I even forgot the borehole one sef.
Our tax collection system is broken so the govt would always try to target who they feel has money to spend (check private jets, duties etc)
Remember radio taxes where/are a thing.
That's a future thing to worry about though.
ceaser: Bro, please let's not be prophets of doom. If such ever happens and I pray it does not, it is going to be a very ugly scenario and believe me, intense suffering for Nigerians. Remember, the plan to start such things for people sinking boreholes for home/residential water supply? Thank goodness that the idea somehow did not see the light of the day.
I see this coming soon. Govt can't see people spending money and allow them rest.
ceaser: I don't think that option comes with the freedom associated with solar generation which has a much less, nearly negligible footprint on the environment. If no be for God, the government would have legislated to have all solar enthusiasts prosecuted except they seek operating licences which has to be regularly renewed.
AMINDA: Good morning house. I am a novice in inverter matters and I intend to get one soon. I need advise and guidance please. Someone is offering a few months used hybrid 2.4kva De-bull inverter with 2 (telecom) batteries to me at 400k. Is this a good buy in terms of product and value for money? Or is it overpriced? If so, can anyone recommend a better and cheaper deal?
I currently stay in an area where light supply is extremely poor (less than 3 hours a day). My appliances are just basic for now but I need something with good battery backup. Thanks.
Adding to what @PenuelSeun said with less than 3 hours per day power you'd need solar to charge anything properly.
deking: Well detailed but the computation for the solar yield is too idealistic. This is why many clients over expect, installers over promise and at the end disappointment sets it.
The NOCT yield of most solar panels is practically around 19-35%.
This implies that that 1200W setup would at best give him 500W consistent generation for 4-5 hours.
