I purchased the Felicity FL-IVCM5048 with claimed 5KVA (4KW). Quiet small and light. I was wondering if this thing can truly do 4KW. If the company can lie about the capacity of its lithium battery, [b]it shouldn't be difficult for them to lie about the capacity of their inverter[/b]. Special thanks to @Ojeysky for helping me with getting the data from the inverter using solpiplog.

Good evening house...

Please I want experts to help me clear something. I got Epever SCC today rated 30amps 12v/24v. My problem now is that it's written in the manual that maximum pv input should be 360W, whereas I have an arrangement of 4x 150W, making a total of 600w.

Would this be suitable for the SCC or will it damage the device?

Thanks in advance.

ojeysky:


How can it be 30A with maximum of 360w, please check the specification again

This looks dope...

this is nice. solar roofing sheets but those curves might make it lose some efficiency.

Good morning house, I have a fundamental problem that needs advice of the experts and your experience here.
I designated a safe well ventilated part of the house to situate my inverter but I have a problem choosing where to locate the solar panels.

The problems with the alternative solar panels location sites are presented below:

A. Car port.
It is close to the location of the inverter but at 9am, only 30% of the space is exposed to sun, at 10am about 50% and by 11am it is fully exposed to sun till sunset.
It is about 6 to 8m from the location of the inverter.

B. BQ Roof
It is exposed to the sun from about 7am to
to sunset. It is easy to access but it is about 18m from the location of the inverter and if the cables are to be buried underground, an additional length of about 9m needs to be added.

C. Main House Roof.
It's closest to the inverter but the roof is quite steep and the face of the roof selected is limited by the numbers of panels it can take. It's exposed to sunshine from about 7am to sunset. The installers think it's should be avoided.

Kindly advise.
Do I sacrifice the closeness of the car port to loss of 3hrs of sunshine daily?
Or to take advantage of the BQ good expose to sunshine but in the process run close to 30m of cable between the panels and charge controller?

Thank you.

I think you should go with option A

Malevonent:


Option b, use 16mm or 10mm cable and teansmit at above 100v, max of 9 x 330w panels each string.
You would be fine.

I hope ur system is 48v

I posted something earlier about that spaceX guy (Elon Musk) planning something of this sort. But I don't think this is his own exact concept.

His is flat tiles, but this seems to follow the traditional undulating roof format, which makes it more beautiful, that is if it can guarantee adequate electricity output from varying illumination that will occur on the exposed surfaces.

But the pictures look high definition like it's CGI. If they are real pictures, then that's cool evolution.

NiyiOmoIyunade:
I would go with the unshaded BQ roof and use an appropriate cable gauge for power transmission with a suitable MPPT CC.

Depending on the details of your CC you may even add more panels in series to make sufficient voltage to offset transmission line losses - there are online tables that tell you what gauge of cable is needed for a given distance and ampacity at 3% acceptable losses, 5% acceptable losses and so on.

At my current location, two of my PV arrays travel over 30meters from the back of the house to get to the CCs - I used 385w panels, 4 in series with 16mm2 cable from PV combiner to CC here and no trouble or losses so far, of course the PV comes into a 250v/100A CC - the second array is 330w side by side and these are arranged 3 in series with 16MM cable from PV combiner to CC - no losses there either - the only extra I did here is to run 16mm2 cable from the farthest PV string to PV combiner box as it was say 18meter distance for the farthest string - this is vs the typical 6mm2 people use.

Option A may not be your best bet as the direction of shading/shadows changes all year round - you may not have seen the worst situation yet in your short term observations.

From your basic explanation I will say go for either A or B. First ask yourself a few questions. Which is sloped southwards with least slope angle. You know solar orientation changes all year/life round. So those shadows start, stop and orientation will change too.

I don't know if you own the house & can still make corrections but when I was building mine I visited site every time with a compass and sun monitoring. This prompted me to construct my carport sloped southwards & placed with the least shadow effects.

I don't believe the roof is the best place to mount panels in this country especially for us wey slope am up to 2 storey building heights. But if you got no option look for the one wey face south and fill if up first.

As for distance from CC, easily worked around with proper cable sizing. I hope the attached pictures will help.

This is really nice. Even with junction box and MC4. Very neat and good aesthetics.

It's likely gonna be deadly expensive for now sha.

I have some questions to make troubleshooting easier.

1) Did you buy the battery new? --YES ITS NEW

2) What is the total load (total device power) connected to the inverter?---200watts approximately

3) Do you have any idea the maximum charging current and voltage of the inverter? Do you know the cut off voltage of this inverter? That is the lowest voltage that it cuts off the battery?-- NO TO ALL

4) Do you usually run the inverter with NEPA or generator?- NEPA

If generator, do you have any idea the frequency produced by this generator?


If NEPA, do you experience low voltage a lot in your 'hood?-160V minimum... usually around 180-203V
