Funny coincidence. I just watched a Will Prowse You tube bifacial "Signature" brand solar panel review couple of minutes ago and I now see this post, about the first on this thread I think, about bifacial solar panel.

Na the installation go get problem sha. It has to be installed at a much higher level than the average regular panels and placed on a reflective/white surface in order to get the max out of it.

I use bifacial and though it's not a car port setup I still get some hervest from the other side of the Panel so long as there is sunlight ray getting to the other side.. However a carport setup will make sense and more Optimal. It just makes sense to get it especially when price and quality is same with the single faces......one may find a need to change configuration within the 25 years lifespan

Hello Valto. Hello @ Ojesky, @ Niyi, @ all.

Just a quick help here.

60A MakeSkyBlue MPPT already hooked to 3s 2p 360watts panels for a 48v system. Readings on the CC approach 35amps on some sun-smiling days.

Now there is intention to add more panels. But apparently original Felicity 360w are scarce in the market, or rather let me say my trusted supplier has ran out of stock. And I honestly don't want to source from another point until such a time he has stocks available, something which seems to be taking forever.

I know other vendors here may have it, but I've over time developed a relationship with my supplier such that he gives "pay later options" on some days, reason I'd still want to stick with him on the Felicity.

Okay so I thought, maybe I can get 3s configs of other higher or lower rated panels in parallel with it, at least I can source for those from my existing supplier or a new honest supplier altogether if the former has no stocks.

So is it allowed to get something like 410w panel in 2s or 300w panel in 3s or 270w panel in 3s and then parallel the string to the pre-existing 3s 360w on the same MPPT CC?

Will that step be a blunder or it isn't considered counterproductive considering that the VoCs from the new proposed strings will differ from the pre-existing strings?

If I get you right, you already have 6 units of 360 panels wired in 3s2p and you want to add another? You can do 2s of 410w in Parallel with the existing one because you want to get the voltage as close as possible to the existing strings, but note that this is not an optimal setup.

Recently installed a 5.5kwh Smk hybrid on and off grid inverter system coupled with 4 units of 12v 200ah blue carbon lithium ion lifepo4 batteries and 8 450watts mono solar panels. Everything seems fine, but the only downside is that my 9kva firman 12990esr generator can’t seem to charge it. So far only the solar and Nepa light have been able to charge it. But with the raining season on full mode and epileptic power supply, I really need the generator option. My installer said my generator frequency isn’t enough, this is a generator that comfortably powers my 3hp inverter standing AC and 1.5hp inverter AC. What can I do pls? So far from the inverter screen, my gen produces btw 275 -285v and btw 48 - 50.5hz. Shouldn’t this be enough to charge the battery?

I will also look at the generator voltage again, you may also try to apply other loads on the Gen and then see if your inverter starts charging. Try a lower charge rate as well.
That said, will like feedback on this bluecarbon, I see you have 4 so each is 200ah 48v? and you have them in parallel or they are 200ah 12v each and you have them in series?

I greet dem Bosses in the house,

Please i have a very delicate question,

Is is possible to get a solar and inverter only system without battery?

The function of this is to use only solar during the day and switch on nepa/grid at night without having any backup battery in place.

It's important to note that the PV should be the only one working during the day with drawing power from nepa,
And it should be automated in a way that if sun goes down or more power is required it can tap small from grid

Why I'm saying this, is so we don't need to start disconnecting nepa during the day,......

If you are not budget tight then go for Deye as already mentioned. Other budget alternatives are MPP, growatt and sorotec....I don't know Felicity hybrids that support this; they will require some kind of battery no matter how little

Thanks for your reply sir. But sorry how did u come up with 48kw? By my newbie calculation I assumed two 1.5hp to be about 3kw. And for 12 hours (6pm -6am) that should be 36kw right?

You are right sorry I was using 15hrs in my mind (real sunlight starts to taper down from 3pm).
