Can I mix two charge controller pwm and mppt to charge my battery.

How l wish it was 7k would like to get one

lol

This DMerciful is a very nice guy, I am amazed with the way he has been providing guide and help to the guy. This kind of selfless help is not common without immediate gain or reward. Kodus to people like this. :

I need a 130 or 180 or 200 watt panel to add to my current panel installation. Anyone with a trusted and perfectly rated panel here?

Just give me the prices and let meet to transact thanks

chris81964:
The two spikes are a concern. It could be an error or your charger on the inverter is faulty.
It was a pleasure meeting you. I just got to Ogun state. Traffic is trying.

Mr chris happy you got to your destination safely

here are my readings generated from my charge controller, who fit interprete am

Mr Chirs came over to my place today and help me sort out my solar panel problem, even help me upgrade my charge controller fiemware

yeah met with Mr Chris today, he was able to locate my area which is usually difficult, he help me analyze and power requirement and also help me upgrade my firmware. I am happy I met him. thanks Mr Chris. Very easy going and easy to relate with. THANK

Just call Chris, no need to make private business matters public. He is happy to help you out, of course!

Dont have his phone number

HI mr Chris I have a problem with my solar panel, please can I call thee?

Hello Solar Guru in the house I have a solar panel with 260watt (2x130watt) recommended and installed an installer to charge my 200ah battey. The problem is since the day I installed it in July 26th 2016, the highest i have seen is about 120watt, 9amps (lasted for 5secs) but it usuually hover within 10watt to 90watt. If the sun is out it could be 90watt if am lucky.

There are two things I wanna confirm from the guru in the house .

1, for a 260watt panel despite using 30amps MPPT charge controller, is it ok if the panel is outputting 10-90watt on average sun intensity? I am worried cause i am losing about 200watt.

2, If we assume the weather is the cause, what is the likely average watt one can expect from a 260watt panel on a rainy or cloudy day.

3, Finanlly on an a normal sunny day, assuming installation was ok and panel was well positioned, what can be expected?

Need reply for gurus and those who had experience such situations before

still need help

Hi Guys where can I get this training in Lagos. Number 08034288798

Can you please upload a picture of the solar module's name/type plate.
Did you measure the Amps on the solar charger where the battery is connected or directly on the solar panel.
With the multimeter you only can measure I sc (short circuit current), but it does not tell anything about the performance.

Please upload a picture of the panel's front and the specs of your charge controller.

The panel is high up on the roof so kinda difficult to take a pix without a ladder, the name on the panel is Perlight and it a monocrystalline panel 130w(x2). What we did at the point of purchases was measure the volt which was around 18v-19v mid sunny day and on cloudy time it could be around 17v.

I first tried a 30amps Roy solar PMW charge controller and then tried Fangpusung MPPT 30amp charge controller.

Both were the same outcome. After installation and after some days when I noticed that the battery was not charging even when the indicatior was moving up and down on the controller, I borrowed a clamp meter to measure the amp as advised by another installer and that was when I noticed that there was no amp reading from the cable connecting solar panel to controller and the cable connecting controller to battery.

If I had ur number could give u a call to explain better.

Would appreciate if anyone can help

how many gig is it

waoh thanks guys ...lot of answer, really appreciate though I have to confess I am a bit confuse due to the different solution suggested.

I however would like to know if anyone have experience similar situation like mine where they could measure voltage from there solar system but when it came to measuring amp they couldn't get any reading.

Perhaps you could tell me what u did specifically to resolve it.

This youtube video shows similar problem like the one I am having:

iLoveTheSun:
Hello,
you need to check the maximum DC voltage of your controller; < open circuit voltage of the module = 18..19 Volt.
If the maximum DC voltage of the controller is beyond 40 Volt, then I would put the modules in series.
On cloudy days it is better to have higher voltage.

One possible source of problem can be a burnt diode in the small black connection box on the backside of the module.
It is very rare, but it happened several times to some of my modules. I had to replace them.

good luck!

Hi ilovecloud what causes burnt diode, cause i just bought the panel new prior to installing it, and this diode is it something I can find at a nearby electical store? and is it something I can fix myself?

uwadia79:
let's see the type of controller u are using,and check the panels connection well or u read the voltage from the panels direct. if the problem persists chat me up on whatsapp on 08076683788

Voltage from the panel read 19v to 18 v most time

spyglaxx:
Parallel or series connection problem . Type of cable (mm ) and distance. Alaba boys are bringing in fake controllers now. I bought two that are fake 30 amps. Are you in lagos?

the panel were connected in parrellel... I used a ROY Solar pwm charge controller and a Fangpusun mppt charge the cable according to the installer is suppose to be the best don't really no much about cable

I am having problem uploading the pix, though I am still trying to. I have tried two charge controller so far, a ROY Solar pwm charge controller and a Fangpusun mppt charge controller but were 30amp. I used a clamp meter to measure the amp for either of the two controller but got no amp current reading... Please help me

Hi guys this service is still on i case u want it, step by step easy one on one course

still needed

Hi still looking forward to hearing from that beautiful someone

Hi Solar gurus in the house, I recently upgaded my inverter system (200ah battey and 1.2kva inverter) with a solar system, (2 Perlight monocrytalline solar panel 130w each with 30amp charge controller), however there is an issue I have been facing, I notice that after the solar system was set-up and connected to the battery, that the battery wasn't charging as I expected, I go some meter from a friend to measure the voltage and amp coming from the solar to the controller and tthe voltage and amp coming from the controller to the battery and to my surprise I discover that although I had voltage , but there was no amp (current reading) and the funny thing is the battery indicator goes up and down on the controller as if it is charging . please guys I really need your help any advise would be appreciated.

sup

what is the model of the m-audio inface and the studio monitor wanna do a research

So here we go...

1, The number one ingredient is you need to have a passion for music production. It could be hard at the beginning, this is what will see you through those time
2, you need a laptop to begin with
3, DAW - I would suggest FL Studio, easy to use and versatile
4, you need music production education - that where I will like to help out.
5, you need sounds- basic and premium quality vst plugins and sound kits. I have some sound kit and plugins ready to assist anyone just make your request and if I have I will help out.
6, set of good headphones to begin with. I could help suggest some low cost Studio headphones just in case

7, a midi keyboard controller in order to achieve realistic timing and expand your creativity this you can buy as time goes on


Will be dropping more good stuff later

For the upcoming guys out there I will be dropping some info on stuff you need to put together to help you begin your Music Production so stay tune and get bless
