BetaTechnicians:

You're most likely experiencing losses due to wire sizing.

How did you connect the panels
1. in parallel
2. to the charge controller

Share full details of the wiring

Solarrookie:


I recently moved into a remote area and got some tier 4 600 watts mono panels for myself (150 x 4) for a 12 volts setup. I also got a 50 amps PWM charge controller and 10m cable dual core cable.

olopan:
Lets start from the top

1. You use a tier 4 panel-why call it that is beyond me but you have your reasons

But you should expect the four panels to work like 2 good panels with each contributing 25% of its nameplate

2. Charge controller and cable looks just fine, highest those cable with do is get lukewarm in temp.

3. All you have done looks okay, panel to roof space is okay as long as you not slapping them panels to the roof

My advice, don't waste money, if you very sure your panel is clean, then know that your panels are the bad eggs ... I have similar setup one time but with 2 x 150W and highest from it is 17A

So manage it or upgrade, getting MPPT may give you a little gain but you didn't mention your battery.

I leave this to others to take up from here

As my Monicker implies, I am a rookie with "chikini" background in renewable energy.

I recently moved into a remote area and got some tier 4 600 watts mono panels for myself (150 x 4) for a 12 volts setup. I also got a 50 amps PWM charge controller and 10m cable dual core cable.

I arranged the photovoltaic array in parallel for more current (A) and positioned for proper exposure to sun radiation. Although I must confess that the distance from the rooftop to the panel isn't up to 5 inches.

Distance from Panel to CC = 8 Meters.

The reason for this post

1. The highest current I have recorded is 16amps (1st week after installation) at maximum voltage.

2. Now I record less than 12 amps even on sunny days.

3. Total AH per day is within 60 - 66ah.

I have installed a similar setup sometime in the past but with a different chinko 60 amps PWM controller and saw 20amps current output. Something is telling me to call my base and ask them to send me 60amps PWM (That brand i used in the past) but i feel its going to be a wasted effort.

I know you all will say "Buy MPPT", I will buy one by the end of the month for checks but please recommend between EpEver, PowMr and MakeSlyblue.

Expert suggestions will be appreciated.


You guys are king!

I think your major problem may be the charge controller in use and of course the tier 4 PV you are using

If each PV has capability of producing 8A at 18v or 20v, under ideal conditions you should get up to 32A. But the PVs may not working under ideal conditions as there are loses due to wire size, loses too due to tilt angle, shade factors, PWM inefficiency, etc. But you can even out these odds a little by using an MPPT and hopefully increasing the gauge of wire in use. My 3 cents

Thank you King!

I will order for Mppt by month end and update the house.

I appreciate you Sir!

Hello, I need some pre-packaged 48v lithium batteries for my office. Shouldn't be too expensive. Preferably Felicity, but I will consider other ones. Please quote me if you have.

IYGEAL:


Buy Epever


I'm not one of the experts

Thank you so much King!

1. I called them tier 4 because they are chinese variants rebranded as tier 2. They came cheap so I didn't bother to return them to the seller.

2. You are right. It gets lukewarm whenever current hits 16A.

3. I think I failed here �. I slapped em on the roof lol.

Needed electricity so badly. Welder told me to pay 40,000 for angle irons.

Battery is "Fullriver 200ah lead acid".

I appreciate you Sir!

olopan:
If you can get the local alunminum used for Windows .... Either lockstyle or interlock and use to raise your panels up a bit ...

Temperature may be one of its bane here ... You might just get higher power if you try the above procedures.

will get u one from jiji too so u can see it

What inverter do you use?

I would have recommended pylontech Or BYD if you can afford it.... Communication and seamless integration is so much easier with them

wilmaria14:
how do u tell a real solar panel when u see one sir pls I will like to know ?

adrusa:


If I can get any of them for good prices. The office is paying, so there is a little latitude here.

Dam5reey:


Abeg, Rest this case.

From all indication your panel is the original one,
But Awoof dey run be ;Dlle oo..
