Please i need some claerification on a problem (not my personal system)

They have a 12volt 2.2kw hybrid inverter
6pcs of 550w jinko
2.1kwh lithium battery

its just for basic home usage no much load, not even fridge or freezer just pumping machine sometimes.

I personally adviced they can use the freezer when its sunny, they started doing that and it went well but one day they put on the freezer and the inverter entered error 58 and didnt work for 24 hours but later magicall started working again.

Now i am thinking what could have caused that because they said nothing else was even on when it happen, it was majorly just the freezer but it was just after they finished pumping water with it though.

maybe the high surge from the freezer compressor to pick up?

just want to understand what could have happened before they upgrade the system

Inconclusive but did they check the battery voltage and state of charge before turning on the fridge after running the pump?

Because the water pump is not nice to the battery.

It seems the battery did not fully recover when you decided to turn on the fridge.

I could be wrong.

But given my experience running a pump on a 1.5kva inverter, I think is most likely the issue.

Please don't do it again unless you allow the battery to juice up after such a beating.

Have you used the Sako inverter or other transformerless hybrid inverters with a 3000W max on hot plate before ? Seeking feedback from users who have paired transformerless hybrid inverters with high-power appliances (up to 3000W) like electric stoves. Success stories or challenges?

Okay, last month i bought a sako hybrid inverter from a nairalander here (nexus). To cater for the same thing. 3 tanks to be filled at least twice a day. 24v system. Just adding panels gradually but so far, it okay. How many litre tank do you fill.

Yes you can... Once it get to the needed 800w,it will cut the rest 300w plus off... In my own opinion, why not series the panel...? That cc can take up to 150V and 2 550w panel would enter max 100V.
Anyways both way works...

Can i over panel this Felicity mppt 12 volts 800 watts with two 550watts panels( making it 1100 watts) on parallel. Can the mppt handle the oversizing?

Thanks so much for responding. It's actually a 145 volt CC sir.

I dont think that the issue here... For those numbers of jinko panels and capacity, I doubt if it will even take from the battery at all.. And again that is if the pumping was done during good harvest.

Still the 2 550w won't get to that even if you stay at the northern part of the country.

Check the panel data sheet, the voc should be btw 45 and 50max..kindly confirm this pls..

It's 49.82V and my state of residence is kaduna. Should i still go ahead and connect them in series?

what is the advantage of a series connection over a parallel?

it reduces power loss, wire size... some of the many advantages..

But for a small system as yours.. Parallel connect no bad.. Just that its gonna need bigger and plenty wires unlike series connection.

My SRNE 3.3KW hybrid inverter handles my water heater like a champ. Water heater is around 2.5kw.

Gbayi baba mii 🙌 🙌 🙌


Do you use their battery too? Hope hin make plenty sense?

SRNE has got awesome inverters.

Series connection is your best option here. It will give the cc the required voltage to perform it's mppt function.

Nah, I use a battery built by isangjohnson here. Solid so far.

Heater use is also only when I'm getting peak power from sun anyway.

Please does anybody by chance here sell a 36V pure sine wave inverter

One quick question again, what the capacity of your heater...?

@olatade
Series your pv and see the wonders of great output from your cc. Your cc will convert the rest voltage into usable amp. You will smile .

No i haven't, the sako hybrid was for a pumping project. But if you want to get an hybrid with transformers go for Felicity hybrid.

Thanks for the advice bro

Your last sentence should have come first in the form of a condition:

Provided that the pumping of the water and the turning on of the fridge happened during good PV harvest then ....

But instead you put it last giving the impression that you were making a categorical statement earlier on.

That said the guy made a telling statement, that it happened immediately after two conditions were fulfilled, first, the pumping of the water and second,
the turning on of the fridge.

That could (note not should) lead to the conclusion or assumption that they are related.

He did not state whether he was in a good harvest or a bad harvest season.

So without knowing all the variables, it is safe to not be categorical.

I did include a disclaimer that I could very well be wrong, but my experience has been that if the battery goes too low, the inverter either registers a fault code or doesn't turn on at all or just goes off.

There are at least three other variables we don't know: the capacity of the water pump aka how fast it ran down the battery or used up the juice from the PV

the state of the charge or discharge of the battery when he started to pump

how long the pump ran aka how far gone the battery was as at the time he turned on the fridge

Which might (note I said might not must) have caused the inverter to go into self-protection mode.

How is the Sako inverter. Is it still performing ok? How many KvA is the one you bought

Dam5reey:
Durability time will tell, they have 3 years warranty and support is available from the factory, as well as local support.
We managed to set up communication between the 6.2KW inverter and the 5KWH.
The Inverter can now read the correct SOC from the batteries.

Boss, is this the battery app or the inverter app

samnaija:
I got it for a friend, so i only check up on the system on weekends. But what i could sample for now it carries one pump at a time.
2 surface pump ( 1hp).
1 submersible pump (1.5hp).

The first cycle starts in the morning 10 am.
Second pump cycle starts at 3 pm.
All 3 tanks are filled twice a day. For fish farming.

Sako hybrid 3.5 kva 24v.

Wouldn't He save more power investing in water recycling. All these almost everyDay pumping of water would reduce drastically

futurenix:
Take it to felicity service center for repairs. There is something not good about those new felicity solar charge controller.

They repaired it then but it developed another fault 2 weeks ago. Still thinking of how to send to them again.

especially when you think of cost of transporting yourself to and fro their service center.

This is Inverter app, This 6.2kva version has local WiFi for monitoring..

Not holding brief for the seller, but I've bought an item from that guy before. Although I went to pick the item and paid cash.

bassdow:

To be honest, i don't really know much about the water recycling, but if i may ask wont it involve pumping from one point to another then back again. This will require energy and pump.
The fish farming is a very stinky business,the stench from the water not changed in two days is out of this world.

Yes still requires pumping water (recycling the water) from the pond, into a small drum (say those blue drum of 200 litres) back into same pond. That way, it's same water.
As for the pump, it uses smaller pumps that costs less than 15,000 naira brand new and runs on say 12-volts power source.

The purification happens inside the small drum.

Funny thing is, we don't need such app most time. I see these things as nothing but selling point and means to extract more money from people but then, it keeps them in business
