No voltage at the terminals using multimeter.
CC does not see the battery
Inverter does not too.

Guess it's time to send it back. Their china technical office sent a message now saying a fuse must have broken inside and should be returned to the service center.

Thought I could rectify it without tempering the screws and save to and fro 40k for waybil and time.

From your explanation, I think the bms doesn't bring out the output. That bms may be changed.

bassdow:

first, your pictures says nothing about if it's for an ISP, or a financial institution.

Secondly, even if they do, which I know, the numbers are so small it's as good as none.

Thridly, have repeatedly made it clear I believe lithium technology is more performant BUT because it's very difficult getting genuine cells, it's more adviceAble sticking to Acid batteries. There's a reason I don't use LG products despite they having various showRooms all over the place.

Probably same reason Tokunbo appliances cost as much as brand new ones in Nigeria

You no dey ever gree.

BlueStripper:



Thank you so much Sir. Since last week I made up my mind to upgrade to a 24v system.

If anyone has a 24v system for sale, 2.5 to 3.5kva, please let me know.

I beg, the inverter must have low power consumption. I don't want to add more troubles to my trouble.



Insha Allah, I am buying a bigger lithium pack from Valto. Since I tasted Lithium, I have had peace of mind.

I don't know which devil pushed me to buy this Tubular Batteries. I regret it Walahi.

I have an open box, pure sine wave 1.6kw sachet inverter. Low idle power consumption. ...Also solar panels of various capacities, both used and new.

Shoot me a mail if interested.

The fuse in your second picture can be found in AliExpress but I dont have any idea where you can buy this in Nigeria.

See the link below where you can buy it in AliExpress. I have the 200amp MEGA fuse but you need 150a.

Also note, the max rated volt for MEGA fuse is 32v while the fuse Felicity used in my battery is rated for 70v. The little I know about fuse is, if you go higher than the rated voltage, the breaking capacity reduces.

My advise, reach out to Felicity & let them send you the fuse.

Are you 100% sure the problem is the fuse? Did you use a multimeter to check for continuity? If the fuse is blown, temporarily bypass the fuse & see if the BMS will come on.

Pls anyone with info on where to get this fuse model? 150A

Dear Team.

Please, I have a 24v 100ah lifepo4 battery pack. Please, what kind of charger(AC) is it recommended that I use.

Note that we have regular power supply in my area and I am not planning on getting panels.

Considering my points above, what kind and size of inverter is recommended as well?

Do I get a separate charger and inverter or do I get an inverter that can charge?

Total load - 150w fridge and 80w fan primarily.. Abeg no air me bosses.

will be hard to get a compatible 24v lifepo4 lithium battery charger or a cheaper 24v inverter that will match your battery.. your best bet is a 24v 3kw hybrid inverter available at 300k

Check the link, its future proof with 40A inbult solar charge controller... 1.2KW with 3.6KW Surge rating will handle your loads.

Good evening bosses..... Is it advisable to by pass hybrid inverter inbuilt charger and use a separate 60a MPPT charge controller for a 48v system with 8 units of 350w panels connected in 2s 4p ?

Sure, You can use an external controller with your Hybrid..

Hello house. Pls can i connect these 2 solar panels in series
PANEL 1
Vmp- 35.21v
Imp- 13.49A
Voc- 42.54v
Isc- 14.23A

PANEL 2
Vmp- 43.38v
Imp- 10.95A
Voc- 52.24v
Isc- 11.77A

Pls note that both panels are CONFIRMED original jinko panels bought frm different trusted sources. And both are 475w panels.

In Series Result: 90w loss.
vmp 43.38 + 35.21 = 78.59 V
IMP = Lowest Amperage = 10.95A
That's 860W total as compared to two identical 475 panels 950W.

In parallel Result: 90w loss.
Vmp = Lowest voltage = 35.21 V
IMP = 13.49 + 10.95 = 24.44 A
That's 860W total as compared to two identical 475 panels 950W.

what is your standard warranty on this sir?

Thanks for the response.
So best advise to prevent losses is to get a separate charge controller for both panels?
The total panels are 10. The owner initially installed 7 panels (PANEL 2), then he recently bought 3 panels (PANEL 1) to upgrade the installation from another source (Fouani).

Installed 7 panels? What configuration did he use?

I'll suggest you go ahead with the addition if your CC can accommodate it. Remember that your PV rarely stays at Pmp state for so long. Except budget is not a problem.

You know say na Una dey convince people say dem fit Mix & Match Solar panels of different capacities. Now you're seeing the result.
Wonder why you guys won't let somethings be, so those who really knows what they're doing, to take such risks.

Once again, whenever you combine Solar Panels of different capacities, expect the higher ones to come down to level of the lowest. At end of the day, na you go dey cheat yourself.

The same way you dey advice on Lead-acid.
the loss here is only 10%
If the person doesn't have a choice or the panel was gotten for free or similar why not!!

You can combine them all in series but note that there will be about 10% loss.
with about 5KW PV, it doesn't matter.. losses cannot be avoided when batteries are full and nowhere for power to go.
If cost is not an issue, proceed to get Separate controller for the new panels.

Those are edge cases better left to those who knows what they're doing in certain special circumstances.

you say "the loss here is only 10%" BUT many of us know that's extra avoidAble 10% added to many other losses that's mostly unAvoidable.

Have seen such used on client's project at least on 2 occassions. I recall even sharing one in here. na so the person just combine multiple 200w with multiple 150w solar panels and said client was a first timer. So excuse of getting for free, or reusing what's existing doesn't occur either.

why claim try saving cost, but still make such clients spend on unnecessary accessories such as rails, copper cables, etc. Some would even suggest Bifacial solar panels sef. What an irony
