Please how much does it cost normally to mount 2 solar panels on the roof of a Bungalow in Port Harcourt.

I moved to a new place and want to do a roof mount as no floor space but the prices I'm hearing I don't understand.

It shouldn't be more than 15k, if you buy the aluminum holders for the panel. About a year ago I paid 30k to hang 6 panels.

Every other connection is okay just to put the panels with existing wire.

I don't know how to set the charge controller.

It's all connected in parallel, 24v 200w x 6 in parallel

samnaija:


The setting in your charge controller needs adjustment. I have used this before. The interface is terrible.

You have to fiddle with the second button press it once, an item will start blinking on the display.
Now press the first button leave your finger on it for more than 10 seconds.
You will enter an interface that says L40 , H 40 or F35 written on the display
H40 is your bulk
F35 is your float
L 40 is your low voltage cut.
Use button one to increase each of this .
Finished press menu to exit

I don't use lithium, so I don't know their float voltage or bulk voltage...
And of course it is pwm.

Thank you, I've called the technician to change it to 48 volt, I will study the changes and see if I should get a better charge controller and of course get thicker cables.

I used your settings and the H is maxed at 30v at F at 27 and the L at 24 or so.

Chinese people and fake product, why sell a PWM controller disguised as MPTT.

Recommend one I can use, I will go and buy it asap.
I shutdown the whole system and measured the voltage with a meter it was at 41v.
I restarted the system and the controller stepped it down to 26.5 to 27.5 v the amps can go as high as 50amps.
Is it normal for 24v 1200w parallel to go as high as 41v+?
if yes what controller should I invest in for better performance.

First [b]your charge controller is PWM not MPPT [/b]secondly, confirm the settings on your CC, thirdly,confirm the orientation of ur panels.
Then lastly, if possible ask your installer to change the configuration of your panels to 2s3p as I believe this is more optimal.

NB: These are simply my thoughts....... Others will add and correct... Cheers

coldcandy:


Why do you have to change it to 48v? Your battery is 24v system or you want to change the battery too?
Just like somebody has suggested, change the CC to a proper 24v mppt, configure the settings and observe for a while.

Moneyboyz:


I just blew my inverter sef, the 48 volt somehow blew my inverter, I hope it's the fuse and not something else. I will go and get a felicity charge controller Tomorrow.

gadgetplanetng:


The battery to 48v or cc setting to 48v?

Moneyboyz:


Solar from 24 parallel to 48 series. Somehow it blew my inverter.

Penuelseun:
better change it back before you destroy your battery BMS, told you before to contact a professional. It is not everything you thinker with especially when you have no idea about how it works

Oshomo12:
If you are a lawyer, stick to the law, doctor, stick to medicine, and most especially if you don't know anything about electricity, dc/ac, stay clear of solar DIY. If you don't love yourself, don't risk the life of your loved ones. How much do you think you are saving by touching what you have no idea of? That was a very expensive mistake.
Well, life is so cheap in Nigeria.

gadgetplanetng:
With the way the average professionals behave it's better we learn.

I know what I went through in the hands of "expert" mechanics till I started learning about cars.

Same thing with solar.

If we stopped trying after falling the first time learning to walk as babies we won't ever walk.

He made a mistake, let him learn.

A professional probably suggested that "mppt" for him.

Juror:

For the load on inverter,
You may need external peripherals for that. For example, add a wattmeter or limiter that gives details of output voltage and current. That's what I did for an installation with TBB inverter.

And you may be asking for too much when asking for how long the battery would take to charge full or how long it'll last. Most inverters don't provide this information too, you may be able to estimate it based on other devices & plugins (Charge controller that logs, BMS that communicates, in-line amp meters etc etc )or history.


Possibly your next question would be to ask for Charge controllers that logs etc? lol

While not intending to ruin your parade, I hope you don't end up in a questioning loop/abyss. You need to take a decision based on the myriads of information provided to you(for some weeks now) while taking into consideration your constraints (budget, load, environment).

Some years ago I started my car and it caught fire

Why?

Trusted mechanic didn't plug in engine fuel supply hose properly after working so it disconnected during the day and poured fuel on the hot engine when I tried to start it.

If I had known and double checked what he did would have noticed it and avoided that trauma.

I'm alive today is God's grace

"Stay in your lane" encourages ignorance which doesn't help anybody even the experts were not born with the wisdom, they made mistakes and learnt.

A pack of 8 brand new 230ah Eve cells still available @80k each. Reachout if interested... Make a 24k pack or 2 units of 12v packs.

DM for price works for me bro a honest serious buyer slides into DM and seal deals, not asking and haggling prices on open forum and spamming the thread.

Malevonent:

Whatever rocks your boat, bro.

Valto:
i have many items of different specs for sale, u dont expect me to list thier numerous prices on a serious solar discussion thread. btw, here is not a supermarket either . thanks

truthbetold22:


E be like this Valto guy go worse pass Kiekie!

Malevonent:


omo, he is sounding like a mix of the legendary kiekie and zeestone.

TechGeek777:


Okay thanks. But how were you able to perform equalization and specify the battery type (e.g. flooded or SMF) to be used with this inverter?
