Don't. Mind you, when you mix 2 batteries of varying capacity and strength, the WEAKer would kill the STRONGer

I've seen some advanced mix of lead and lithium on YouTube. Some people said it can be done with good BMS or separating the two battery types, with the lithium acting as a charger.
There is a possibility of using a load-based function to stop the voltage sag of lead using the lithium, when large loads are applied.
I want to know any Naija man wey don do am.

Fakeisfake:
Bros, this was my problem with Lead Acid too... I became a "manager of power sagging management" with LA until I got Lithium I didn't know life is this sweet..

Imagine at evening after work, fridge is on, family is microwaving, in the morning as early as 6am they are microwaving for school and me going to work yet lithium stands strong without sagging but gradual diplation...

Please why is Lead Acid still in the market?

I have connected an LFP and SLA together before, in parallel. It worked ok.

I set the CC settings to favour the lead acid though. The LFP BMS simply protects the lithium

Reports coming out suggest that the Afriland Towers Fire was started in the INVERTER ROOM.

"According to the Federal Fire Service team leader from Ebute Metta, Mr Ehimen Momoh, the fire started from an inverter battery in the basement and spread to a parked Toyota Sienna and a motorcycle, both of which were completely burnt. Other vehicles in the basement were, however, saved."

Its very important that if you are installing solar systems to get EXPERIENCED installers who calculate load, wiring sizes and use fuses, breakers properly. Ensure that you also install smoke detectors and a fire extinguisher nearby in case of fire.

Help me ask people like Georged1 who are still living in delusion and trying to encourage themselves that lead acid is a superior technology!!

Think it isn't very likely that such a facility would use hacks to handle their solar installation. As long as it's electricity, there's always a risk of fire--doesn't necessarily have to be a case of bad installation.

But yeah, things like smoke detectors and extinguishers are always necessary to mitigate damage if it happens.

Please make your point without mentioning any names. Respect that username please as he was the one who opened our eyes in this thread to the endless possibilities of renewable and affordable energy

A delusion is an unshakeable, false belief that is maintained despite clear evidence to the contrary.

The use of the word wasn’t meant to be disrespect. However, for the records, he opened “your” eyes. Some of us knew about solar before Nairaland.

Just because he or anyone else opens or starts a thread, it now means they cannot be mentioned and they should be treated like “gods?”

Hi guys, does anyone know why some manufacturers say you can't parallel their LFP. My thinking was one should be able to parallel LFP since they have separate BMS .Just asking for knowledge sake

I've personally seen a fire that started in an inverter room at a bank, and it turned out a faulty AC was the culprit. The AC caught fire, and melted rubber dripped onto batteries stacked below it, which were subsequently engulfed in flames. Without the CCTV video, many might have thought the inverter system was to blame.

​Anyway, nothing still beats using experienced installers or workers for your job. You can't cheap out on safety.

​Also, I wonder why our tall buildings in Nigeria don't have fire escapes. This is especially concerning since our Fire Service lacks the capacity to rescue people stuck in high-rises during fires.

​I just hope people install fire safety devices, like FM-200 fire extinguishers, in such sensitive areas

@ dam5reey1 and others, please which is better to use, Haisic 25.6v 8kwh battery or Sungene 25.6v 300ah lithium battery.

Dam5reey1, have you done capacity check and tear down of any? Any good result from them

These 2 batteries appears to be cheaper and compared to DIY of mrreed and valto.

Good morning to you all

Please I need the in house utmost input.
My akt 120w solar flood light (with separate panels), the panel was cart away by unknown person leaving the light casing.

I've been searching for possible solutions to continue using the solar flood light either by getting another panel that could fit into the kit or probably tap D.C current from an another solar panel of 50w through the charge controller(to charge eclectic fence wizard4 machine battery) and cut the kit end on the solar flood light casing and join the wire ([b][/b]Note the original solar panel that comes with it stated 15w, 6v and 3A).

Please I need the house input on this [b][/b]DIY
Thanks in anticipation.

Are you in Nigeria ?

Yes, Ibadan, Nigeria.

I don't see any technical reason why you can not connect batteries with same chemistry and similar voltages in parallel. When batteries are conncetd in parallel, they act as individual batteries merely taking and contributing to the pool based on their internal resistance which depends on capacity and voltage. During charging, they take what they need and stop taking once they are full. During discharging, they give whatever they have until their voltages get to that of thers in the parrallel configuration. It is the same behaviour whether there is a BMS or not.

However, manufacturers sometimes give specific instructions about their products, not for technical reasons, but for warranty purposes. It gives them the opportunity to dodge warranty claims if they can prove that your usage was "out of specification". It also helps them simplify troubleshooting when their is a problem.

By the way, I currently run four LFP batteries in parrallel. Two have JK-BMS, one has an ANT BMS and the last has a JBD BMS. They have been running in harmony for years now with no problem. I'm able to monitor the performance of each of them through their smart BMSes.

An electrician (those locally called RadioNic) that repairs Televisions should be able to help out. Alternatively, if you set for work, then share more pictures so we direct you accordingly.

I have two ABB meters I used for something like this. Very rugged. Drop your digts.

Abuzz33, is this meter still available?

Thanks what about Sungene pls

Is there anyone in the house that have experience with sungene
Please help a brother choose between the 2 batteries.

Where were you when solar panels are being lock up on the roof after installation and u claim solar discussion existed long B4 Nairaland,that I might disagree with, anyways u are entitled to ur opinion.
But these great Nigerians made this thread thick back then and encouraged many of us in this journey of fta and solar ,so if they are seen as gods here on this thread,they deserved it

Yh
Its around 690k on jumia
Have you heard any reviews on it so far
Im stuck between getting it or delta 2 ecoflow

Personally I'll prefer the HeroEE 2 than the Delta 2 cos of aftersales service. Hithium has service centres now in PH and Lagos... I doubt ull be able to replace a part or fixthe Delta 2 if it gets bad 2 years later

Which means that there was nothing installed so they could remotely monitor that room and the installations therein so that they could respond before the crisis got out of control.

When building alternative power supplies for critical infrastructure such as that building, we aren't supposed to stop at just the power equipment, but there should be sensors and meters monitoring the alternative power supply as well as people assigned to monitor those sensors and meters on shift.

At the electricity utility level, we have SCADA.

There is something similar available for such a building so sad.

Back in the day we deployed an fm200 installation in our ups server room. At the time it must also have looked to mgt like oversabi.

Already suggested He avoids anything All-In-One except the cost of said system is nothing to his finances. The money wey some of us dey struggle to gather and spend, na Beer money to some others.

Things such as this looks to superiors like waste of funds. Just like data backUps, it continues looking like waste of funds till the very day you need it

This is incorrect. Ecoflow has a functional after sales center too in Lagos and environs.
We retail them and know this.

This a typical example what this forum has become, someone cannot give his personal experience and opinion on what they use, because it differs from yours he is delusional.

Well sorry to burst your bubble , we plenty still using lead acid. And years are counting and no regrets. If that eats up, my brother go hug transformer .
