I understand your point, Bro.

Just because a Product is New in the Market, or the Name is Chinese or does not 'ring a Bell' or even because it is NOT Expensive, does not mean it is of Bad or of low quality!

In Nigeria, we usually associate "quality" with "High Price" but experience has shown that Sellers are capitalizing on our assumptions and just upping the Price for us.

Some Sellers are New therefore, their Products are relatively Unknown.
But they want to "break" into the Market and make a name for themselves so, they (initially) reduce their Prices, to attract Customers since they know that we are all Price-sensitive!

It is after they have established The Quality of their Product in the Market, made a Name for themselves, that they then revert to Normal or even higher Prices.

My suggestion:
- Read Reviews, from those who have actually bought and used the Product.
-Rread such Reviews from Reputable and Independent Sites like TrustPilot.
- Check the Sales level of the Product: the more the Buyers, the more trustworthy their Reviews
- Pay attention to their "Warranty & Returns Policy": Manufacturers who have confidence in their Products, are not afraid to offer long Warranties and will make 'Returns' very easy for their Buyers, should they have any issue with their Product. They are just confident that only a very tiny Fraction of Buyers will have the need to Return their Product


BTW: I was having this same discussion an hour ago, with my youngest Child, a University Freshman, who wants to buy a Soldering Iron for one of his Engineering Courses and we saw a "Cheap One" that has Temperature Control, On/Off Switch, Extra Solder Tips, etc.
His immediate response was: Dad, l dont want that One, if it is that cheap, it cant be that good!
Young Man did not even bother to read the reviews or any of the other things l mentioned above.
Ofcourse, l am the one Paying, shey you get.

bassdow:
would have suggested you share screenshot of their stickers.

Make we no go assume. Have seen Jinko panels with funny looking junctionBoxes but with jinKo sticker.

Also no be only VOC that's to be considered

Also are you handling things yourSelf or outSourcing ?

idsolar:
Thanks for ur response, I am handling the installation. I am going for upgrade. The panels are already installed on non hybrid with CC, now upgrading to hybrid. Though VOC total not up to 450v which is safe and within limit but just asking if Jinko panels from experience use to have voltage spike or any install closer or over my VOC working well without issue

Gshems:
Your fear should be the max amperage. You need to series all 9 panels to be safe. So confirm what configuration the panels are currently on

FEGEITOK:
Please I need TOMZN TOB9DC-63 or dedicated Tuya DC Smart MCB (stamped DC 8V–90V)?

bassdow:
which is why I suggested we see the stickers.

Because when e sheyLe, na We e go blame - which is quite understandable

Glad to hear He/She is personally handling it though to a lot of us, it's a loss of Revenue abi inCome

idsolar:
The 9pcs Jinko panels are currently running on series and parallel. I am upgrading with hybrid on MPPT VOC max 500v. With total panel VOC of 443.34v, though within range, I just want a second opinion from experience, have you installed close to this range and working without issue of voltage spike? Thank you

Good afternoon my bosses, please enlighten me on this issue. I'm stuck between buying Itel power tank ( 1000wh ) and building the pack myself a 12v system ( Lifep04 , 125AH ).

I do not much load , my major needs is Laptop, Router, Fan and to charge phone.

Thank you.

JUST so You Know: There are clients who wanna sell Itel Power Tank just in case you interested.

rePeatedly, we've shared and discussed, and even argued the PROS and CONs of such systems hence wouldn't wanna go back to it.

BUT

If I were in ya shoes, and don't wanna spend much, I would do the below:

Ensure Fan is DC. Have shared how to buy them at dirt CHEAP prices and wouldn't be rePEATing ma self again

Buy 1pcs Brand New 625w halfCut mono solar panel or 2pcs of USEd 350w Mono solar panel for not more than 100k

1pcs quality 12v 200Ah battery (New or USEd). If Lithium, feel free to do 100A but if leadAcid, must be at least 200AH

A quality USEd 60A MPPT charge controller for <= 100k

1pcs of DC 400W 15A step up boost converter or similar for approximately 10k

With the above, you can power your loads and even add 2 more laptops and could even add TV if it's the type that uses external power adapter.

NB: The above gives 100% room for fuuture upGrades with almost no reason to reSale anything which is often one major way to loose.

Guys, I think I’ll need a technician to come check out my inverter.
The inverter shut down even though the battery still had 25% left. After that, it stopped charging from both the grid and PV, and it only comes on when I switch on the PV.
I eventually switched off the inverter and the battery. When I tried powering it back on, the inverter wouldn’t come on by itself. it only comes on when I switch on the PV, but it still won’t charge. It keeps blinking red, which looks like a fault.
A similar issue happened a few weeks ago. When I called the installer, he just dusted off the inverter, re-screwed the battery connections, and it worked fine again.
Now the same problem has started. I also noticed that the fan no longer makes any noise, which usually means it’s not charging.
@bassdow @valto

bassdow:
no be low Battery I dey see for screen so ?

Also depending on the configuration, that 25% could be the cutOff.

Also those battery percentage ain't always accurate. I sense the battery's BMS don lockUp to prevent issues.

That error 3 na mostly over voltage but just try charge that battery first. if e no gree, call ya installer to assist you. Currently too busy to type plenty

Okay I have called the installer and he said he’ll come tomorrow. The issue now is that this same thing happened 2 weeks ago, all he did was re tightened the screw that connects the battery to the inverter, then he opened the inverter and cleaned the inside because it was dusty and it started working well. Now the same issue has started and the battery won’t even charge, both by grid and PV. What do you think may be the cause? It’s been over 8 hours and it’s still the same thing
