You too like big English. You for just tell am make him provide a size reference.

I know the guy don sell the CC but for record purposes the CC would have worked well.
CCs can tolerate over panelling but not overvoltage.
So, what the CC does is take the maximum of 1650w @24v and ignored the rest. Many people on this forum recognised that and overpanel for cloudy days where production may be severely affected.

To determine the expected daily generation of the panels, a factor of 0.7 (inefficiency factor, wiring, distance, cloud cover etc) X total panels X hours of insolation.
2400w X 0.7= 1680w well within the range of the 1650w @24v.

Benefit? He would have been making full use of his money without extra expenditure.

There is absolutely certainty that four panels will be giving him about 1200w/h only

My SRNE 3.3kw has been pretty much rock solid for two years. And I load it up all the time.

handled their products BUT not this your "all in one stackable unit"

I got this particular panel and I thought it was just small panel till it got delivered. Infact I had to wait till everyone was out and in the evening before I installed because I know if the landlady see it, she might not accept to get it installed. Now the installer is telling me that I’ll need atleast 2 to allow my inverter to charge fast. I was like which kind wahala be this one. A 1.5kva inverter though.
Now my question is, can I get a lower panel like 200 watt to compliment it or I’ll have to buy that exact 535 watt bi facial panel again?
Meanwhile since I installed it 5 days ago, the highest it has produced is 250 watt and lower, I don’t know it it is due to the weather or that is the highest it would be generating

I have 3x 550w jinko for my 12v 2kva inverter and on a regular charging I get 350w, I need to mention that I treat it like an egg, max load it takes is less than 150w, but I get up to 1.2kw input from the panels when I am blending during the day. I think some of these inverters behaves like ajebo when they don't have enough loads.

cyif2003:
And any reviews

Gshems:
Well I have 2 535w and I get 650w before 10am it only reduces when my battery is full

Gshems:
2 possibilities : it's either it is a fake or the angle that you installed it.

Unfaized:
Increase your pv charging current for maximum yield. Probably stuck at 40A.

Unfaized:
Check your inverter settings and increase charging current to about 80A (This should improve your output from panel)
Either way you still need extra same panel to charge efficiently.

What's your battery size?

hoover420:
Thing is I don’t even know how to increase the charging from the inverter and I hope increasing it won’t have effect on the inverter?
Battery size is just 3.6kwh

SourYoghurt:
it's 60a

Unfaized:
Which inverter do you use? Check the manual you should see how it's done. Pretty easy.

And no it won't have any effect on inverter. Lithium batteries can take up to 100A depending on the battery bms.

hoover420:
I use the Haisic 1.5kva inverter. I’ll check the manual once I close from work on how to increase it. Thanks

hoover420:
Quick question, once the battery is full, any watt coming from the panel will be used on any load carried on the inverter right. I mean if my total load is 250w and the PV is producing above that, does that mean we are using the sun directly?

Unfaized:
You're welcome.

You just need to press the down arrow 5 times to menu option 6, you should see the current max pv input current, press enter, the value should start blinking, use down arrow to increase till 80A, press enter and return.

The angle it was installed is very okay. And I got the panel from CDcare and I expect them to be selling original products only. If it isn’t from the connection then I believe I bought fake Jinko panel from CDCARE

bassdow:
you mean both are MONO but both are not halfCut ?

if issue is BOTH are not halfCut, no much wahala, continue using them like that BUT as money comes, buy more halfCuts so you phase out the Ordinary ones.

Hopefully, the solar panels are at least 400w each so you don't end up having lots of 200w panels

Unfaized:
Increase it. Mind you, once battery is full it will cut down yield to match load on inverter.

SourYoghurt:
to how many?

Unfaized:
Which battery are you using? LiFePO4 can take up to 100A. But do 80A and check.

osayuwamwen:
cdcare don't sell fake and beside u can confirm the panel serial number on jinko website, but easier way to check the panel efficiency if u are using hybrid inverter just put a load of 1000watt during a very sunny they you see that the yield will be much closer to 535watt may around 400watt plus or u increase the charging current of the inverter
