i have a fangpusun 50D mppt charge controller, that got bad. the cables from the battery was wrongly put in the pv input, while the pv cables was put in the battery out of the CC, it released the blue smoke and smell, i later opened it, and couldnt see anything burnt or wrong. anybody h experienced this or knows how to solve it

Work done and dusted by my professional installer, Mr Aliu. Thanks to Mr Osita for the patronage, God bless you sir.

2 unit of 200Ah 24v felicity lithium battery
8pcs of 380w prime solar panels
1pcs of 5kva 48v MUST hybrid inverter.

Hello, nice sacarsm but that's company formal information as quoted but kindly ignore if not interested Sir .. Cheer's

ceaser:


Does that imply that the two units 24v200ah Felicity lithium are connected in series? I think a single 48v200ah would be good, right?

issy1500:



I have been using the 1.6kva(24v) and Tubular battery for a while now without any issues. The brand is not bad.

ceaser:


Sorry about your CC. I keep hearing this "blue smoke" phrase when it comes to CC frying. Is the smoke actually blue coloured and is it with all CCs or with select ones?

NiyiOmoIyunade:
It may be useful to know whether or not your CC also comes prepackaged with this blue/white smoke.

The whole idea is to give you visual and olfactory clues when something is not right.

So if you reverse the connections e.g. plug the battery cables into the PV terminals of the CC and plug the PV cables from the solar panel into the battery terminals of the CC, then you should release some smoke and afterwards you would be alright. Such a connection will usually blow out the capacitors on the CC battery side at a minimum and this should be a fairly easy replacement part also giving you a chance to open up and see your CC's internals

Be sure to let us know the particular color of warning smoke the test CC released so we can all update our records.

ceaser:


Thanks. I will try that in the at daybreak preferably when the sun is not high up in the sky so as to minimize the damage.

Shebi you said it's just a capacitor that will kaput at the minimum and it should be fairly replaceable? I will keep guys posted.

Thanks once again.

NiyiOmoIyunade:
Please don't do it o!

I was just playing along with your original joke.

On the average a CC made to support up to 48vdc nominal battery will have caps rated for say 72v or so on the battery side, if you plug in say 105v from PV early in the morning surely you will cause serious damage.

Releasing the white/blue smoke is euphemistic for damaging a CC badly.

Still trying to get a hang of the lifepo4 battery.
So which is preferable for an amateur, buying single cells & building a bank, or buying a ready made bank.

2ndly which is preferable, bank made up of say 48 units 3.2v x 100ah cells or 16 units 300ah cells.

Is Rs 485 port critical,
if yes Does the RS 485 only need to know the current and voltage of battery pack ?or it need to connect with inverter?

Lastly, CATL and green power cells, which is preferable?.
Basic research favours CATL, however i want firsthand reviews

ceaser:


Two out of the three battery packs I have are made of CATL. I actually inquired from the guy that sold the pack to make sure he will be using that.

Another good one is CALB. I've not really heard about Greenleaf before.

Hello,
Please i use a 1.5KVA/24V Solar Hybrid Luminous its working very well
I intend to add 2 extra batteries. I know charge time will be longer for 4 batteries as against 2 batteries.
Please can it Charge it well without any adverse effect on the inverter or batteries?

funken:
Who sold the packs to you? Was it here in Nigeria? And how have they been behaving? Thinking of going all lithium...
Appreciate the info...

My inverter trips when senses high load once an inductive load as low as 10w is started. The inverter is rated for 3000w. The product name is Power system. I start noticing this problem since i started using my washing machine on the inverter. Now any little load ,it will sense it as high low and trip. Sometimes the cooling fan won't cut out even after the load has been switched off.
By design once there is a high load on the inverter, it will automatically starts the fan to cool and cut off the fan once the load is removed. But what is happening now is that the fan will remain and don't stop.
Has any one experience such before so i can think of what to do to rectify it.

My normal operational load on the inverter is below 15% load and maximum is around 20-25%.

I have a similar set-up (1.6KVA - 24V) and I added 2 more batteries and it all cool.In my case my inverter has fast charging and power is relatively stable too at least 8-10hrs a day.

I was scared that the Inverter might not be able to fully charge the 4 batteries optimally, so I bought a 50Amp smart charger to support the charging excercise. The 50Amp charger is just there without being put to use because the inverter does the charging perfectly for now.

In my opinion, your inverter should charge the batteries if equiped with fast charging and you do have light for not less than 8-10 hours a day. Though the charging time required for the batteries to get fully charged will be a bit extended.

ceaser:


Yep. In Nigeria. Same guy that supplied Ojeysky. He assembles the packs. He has one year warranty on the packs and he guarantees that cells are grade A with serial numbers/codes that can be used to confirm. So far, the batteries have been doing well.

The third pack was imported already assembled. The cells are not CATL. In fact I don't even know the names of the cells sef, but hey the battery has not disappointed going to 10 months. I believe they'll likely be top grade cells too.

@ojeysky pls who sold your lithiums to you?
@ceaser you can also tell me too. Should I dm you or is it something you can share here? did they come with BMS or its something you had to add yourself?

Ol boy, you have been wasting energy since. Switch to
3s1p you shud see about 45v to 50v coming into the Cc,

, revert to 2s2p when u have 4 x 150w panels
