Do you mean lfp battery is more superior than lithium ion battery in terms of load handling, assuming there are the same capacity?
Lfp could be discharged to 80% dod. Is lithium ion not having the same dod?

Yes, lfp handles load better than lithium ion because lfp has a more stable voltage during its discharge. Lithium ion can also be discharged to 80% but voltage will be much lower and this affects inverters performance.

For comparison, LFP fully charged at13.6v and 12.9v at 80% Dod while lithium ion 12.6v at fully charged and 12.0v at about 20% DOD. Note the voltage difference.


Most times, inverters will hit LVD on some load while using lithium ion despite having a lot of juice but it rarely happens when you make use of LFP (especially when your battery bank is not large).

Though you can correct this by changing the configuration of the lithium ion by changing from 3s to 4s but this usually cause a problem with getting the voltage to work with your inverter especially 12v systems.

It depends on the variant you buy. The first one is original too. The fake dey too but the edges are sharp not curve, the sticker looks like say nah blade dem take cut am. And if by chance u see curve edge with bubbles under it too. Most likely fake. Save ursef the stress n buy from fouani, gennex n other accredited sellers

Pls hw do i identify original Jinko Solar panel from these two stickers.

Make i no go buy fake product, both are priced the same

Thanks

18650 li-ion or which 1 boss
18650 has higher nominal voltage than Lifepo4 nah
Some of them even dey do 1c too
Few do over 1c sef.
Down side is d cycle life
Average Lifepo4 will give u at least 2x of wat 18650 will give
Unless there are other li-ion dey use in solar applications sha

Yes lithium ion do have higher nominal voltage but the voltage sag is more noticeable on lithium ion than lfp.

Though you can correct this by changing the configuration of the lithium ion by changing from 3s to 4s but this usually cause a problem with getting the voltage to work with your inverter especially 12v systems.

li-ion does not do so good in a 12v configuration, best for 24v and 48v systems, has a greater energy density than lifepo4 albeit with lower cycle life. Also 12.0v is not 20% dod for a 3s battery pack as you have a voltage range of 4.2v to 3.0v if you are discharging to 80%. Lfp is also fully charged at 14.4v while 80% dod is at 12.8v

From what I've seen so far, solar generator batteries are mostly build with Li-ion battery pack as it's cheaper in price, lighter in weight, and faster in charging than its lfp battery counterpart.

12.0v is 20% Dod for li-ion 3s configuration. Lfp is fully charge at 13.6v(when the charger is disconnected), 14.4v is the voltage when the battery is still being CHARGED, same thing applies to Lead acid batteries (flooded) charged at 14.2v to 14.6v depending on temperature and while at rest, it's fully charged at 12.7v.
On a final note, depending on your source of information and brand of LFP I'll stick with 12.8v for 80% DOD (to avoid over discharging)

a 3s li-ion pack has a voltage range of 8.4v to 12.6v if you are discharging to 2.8v per cell, so how is 12.0v 20% dod when the batteries are still at 4.0v per cell? Your lifepo4 batteries are fully charged at 14.4v and not at 13.6v, some batteries have a rest voltage of 13.4v depending on how long they have been resting

hi everyone,, am having a hard time choosing between canadian 600w panel, jinko 550w and 580w panel.. am on a tight budget and want to replace some old sticker panels i have...

i would appreciate your comments..

thanks

If the battery breaker trip off while the pv is still supplying power to the hybrid inverter, what would happen to the inverter?
Could it damage the inverter?

The calculation that helped me decide which panel to buy:
To calculate the ratio of watts to dollars for each solar panel, we'll divide the wattage of the panel by its price.

555-watt solar panel:

555 watts / $166,000 ≈ 0.0033 watts per dollar

600-watt solar panel:

600 watts / $202,000 ≈ 0.0029 watts per dollar

670-watt solar panel:

670 watts / $224,000 ≈ 0.0030 watts per dollar

Comparing the ratios, the 555-watt solar panel offers the highest ratio of watts to dollars, indicating that it provides the most wattage for the money.

Substitute dollars for Naira

Add the cost of freight to the cost of the panel for a more accurate figure

No it won't. It would switch to batteryless mode instead.

That is good. Some installers refused to either fuse or install breaker between the CC and the battery, just for the fear of damaging the CC/inverter should the breaker trip off the battery while pv still powering....
I just read somewhere in another forum and also in Victron Community that the CC/inverter would not damage if the battery is disconnected.

There can be damage to some inverters (particularly hybrids) if mains should enter the inverter while there is no battery or battery breaker trips.

Thanks bros i dey go pickup from Gennex tomorrow to avoid stories that touch.

Appreciate ur help sir.

I was reading in the thread of a guy whose system was likely affected by lightning. Imagine spending 100s of thousands in this harsh economy only for your system to be affected by lightning(inverter).

I saw the op of the thread put an arrestor near the solar panel arrays in the beginning of the thread. Can we also have more submissions and pix of setups that have protective measures installed aswell cause like there's more emphasis on installations.

Thank you.

I beg to cheap in here. I do the same analysis when buying solar PV

sharks776:

Using the above analogy, in my case, I regard/use the PV that gives me the lowest cost per cell as the most efficient in terms of cost.

Therefore, the 600w is the most efficient and cost effective PV because it has the lowest cost per watt (i. e 0.0029 watts per dollar)

so you want to pay more for less wattage per USD, interesting...

you will pay 1USD for 0.0029w instead of 1USD for 0.0033w...
