530-580k is the price range

ibietela2:


I dey see 500k, is that the price

Yes that is the inverter

ibietela2:


do you mean this one https://felicitysolar.ng/fl-ivem5048-5kva-48v-hybrid-inverter-with-mppt%EF%BC%9A120-450vdc6000w%E2%89%A412-parallel/?

I am thinking of getting the felicity IVEM 5048, but i just want to be very sure i am not making any mistake buying this inverter. Can anyone who has used this particular brand of inverter or currently using it, tell how durable and rugged this inverter is, coughing out the money and entering one chance will be very painful.

i will be ernestly anticipating people's reponse.

please what could be the issue, my inverter will be showing 24.0v on the display and within less than 2 mins it will jump to 22.3v and the alarm started showing low battery.

Trippledots:


Mine has same issue as. Initially my batteries were balanced but after some months I noticed significant drift. Mixed up the batteries but same thing.

I fear I may have broken the equalizer during reconnection or I need to reset the equalizer.

Either way, my schedule hasn't allowed me to work on the bank again.

What type of balancer do you have?

Edrizz:
With the individual battery voltage u shared, nothing is actually wrong with ur system, u only need to add/install a battery equaliser/balancer to ur system n everything will be fine. Ur 48volt inverter will continue to run provided that the battery voltage is still above 10.5v per piece, once the inverter detects a voltage drop of below 10.50v it would off itself... ur installer ought to have equalised the battery before installing them though

Thank you for your response, i have battery equalizer installed to the batteries and also the system is a 24 voltage system. I thought my batteries were already getting weak.

Please i need expert knowledge here, i have four 220ah tubular battery, i just noticed that when the battery is fully charge and i start using it for the night, @136w(5pm-10pm) and 98w ( 10pm -7am). i noticed that the battery will be 24.2v @2-3am then between 3-4am the battery voltage drops to 23.4v and this will get me to the morning. Recently i had to set the battery SOC from 50% to 70% because at 50% the battery goes off at 5-5:30am but at 70% it takes me till the morning. What could be causing the sharp drop in voltage.

With a battery monitor, i am getting this readings in the morning Batt 1: 11.95v Batt 2: 10.99v batt 3: 10.95v Batt 4: 11.94v

FRESHTWANYE:
Please professional help me I just install 2.4kw pure sinewave mercury hybrid inverter using it with dstv xtraview decoder, the primary decoder working perfectly but the secondary decoder didn't work and loss connection with the primary decoder heart beat. But using it with grid or generator works perfectly for both decoder but when switch to inverter it loss connection, please help me

some mercury 2.4kva inverter are modified sine wave and not pures sine wave, so that could be what might be affection the other decoder

good day All,
Please i need a review on Ipower XMAX 3KVA inverter,
also i need a recommendation for a reliable and good 24v 3kva or above hybrid inverter

I will advise you to leave power xmax alone, it's relatively new in the market and zinox has not really gotten a hand of it, please go for any other ipower brand.

deyem:
But Yohaco hybrid inverter usually has inbuilt charge controller na, why then did you need to buy charge controller

I am using external charge controller becasue it has been there, i just changed the inverter.

Sapiosexuality:
I've been seeing some very high prices here and it made me take it out of my order of things. For this 2.5 KVA 24v hybrid system, do I still need my old MPPT charge controller or it's inbuilt into the inverter? Thanks.

please use your old charge controller and leave out the in-bult charge controller

Good evening

Please I have this kind of configuration setup in my apartment

5kva 24v Inveter
400Watts Solar panels (5)
220ah battery (2)
60amps charger

My question is whenever I try charging with Nepa light o shows it fully charged within few minutes but when it’s on resting stage meaning when it not connect to any form of charge and I check the battery I get 77% even while on solar it shows it fully charged but at the end of the day I see 75% please how can I get it charged to 100% or should I just ignore the fact that it say fully charged and continue charging please any help would be appreciated. Thank you 🙏🏾

please answer this questions

1. what is the battery voltage when is shows 100%
2. what is the Voc of your Charge controller.
3. how was the panels connected, in series, parallel or mixed.
4. what is the panel Voc.

Dam5reey:


You are using a good Batteriy chemistry that allows charging up to 0.5C continuously.
60A on a 173AH batteries is 60/173C that is 0.35C.. So you are fine.

Also note, since the charge controller is limited to 60A If you have inverte powered on, most people tend to use their Fridge during peak periods, so, in essence, your 60A is reduced to about 40A (or less depending on load), left to charge the batteries, so Not all 60A will charge the batteries except you always shut down inverter to charge which may not be the case.

Expect the MPPT charge controller is bad it will always limit the current to what is required to charge the batteries when you turn the inverter off.

Allem:
Happy Sunday all.
Pls can I connect 2 550w panel in parallel to a 12v 173ah system with a 60a PowMr cc. Hope it will not fry the cc?
What exactly will happen
Rain is fast approaching and I don't want to survive like last year.

Please I need this information,
the VOC for the charge controller,
the PV operating voltage for the charge controller,
the Vmp for the panels and
the Imp for the panels.

kristien4:
So sending 60amps into a flooded battery before it reaches near full stage is good for the battery??

you will likely damage the battery.

Drgreatone:

Being curious to know.. while using a 60amp CC with flooded batteries, does it send the whole 60amps into ur batteries while charging? If yes, wont that quickly damage the battery as a result of the high current?

it will never send the whole 60a to the battery, the MPPT charge controller is built to be intelligent to only send what the battery needs for charging, while the others are used to power other loads connected to the inverter. If no load on the inverter it will only send what the battery requires to charge it.

HeavenlyBang:


VOC isn't much of an issue, as you can get past that with smart wiring.

SRNE's 3KVA hybrid for example, is capped at 1440W.

The popular Powmr 60A MPPT CC is capped at 1400W, even. How do people go about it?

So you can over panel your system but ensure your connection does not exceed the specified VOC and Rated Amp for the charge controller. I have a 3600w pannel connection on a 60A, 145v Charge controller and my system is a 24v. what i simply did was to respect the charge controller specification and i have been running it for a year now without issues. The only thing is that the charge controller will limit the wattage been generated to the CC specified cap wattage and waste the others inform of heat.

that is the behaviour of Tubular batteries and most lead acid batteries, it is call voltage sagging. you can read up on it. once you turn off everything, it will return back to its intiate voltage or 5 bars in your case.

Hi House.
My charge controller drops from 5 bar ( 13.6 volts ) to 3bar ( 12.4 volts ) after full charge on a load of 150 watts within 2 minutes.

What could be the issue ? Setup was done a week ago.

Note had to charge with external intelligent 20amps charger to full bar.

This is my set up :
1. 2 x 335 watt GCL panel in series
2. 60 amp PWM Charge controller
3. 220amps Caesar tubular Battery
4. 1KVA MSW Inverter

The main issue is the battery dropping from 5 bar to 3 bar on the charge controller with 2 minutes once load is applied on the the battery.

so guys my set up is as follows

-3.5kva 24 v yohako hybrid inverter
-4 (220AH) batteries
-12 (300W) solar panels
-60A felicity charge controller

I have been partially off-grid, i only get 24 hrs light from Nepa in a week and the rest has been on the solar grid. During the day with everything on, the inveter fridge, inverter deep freezer, the ceiling fans, the standing fans, the washing machine, TVs. With everything on during the day i draw 400w-700w but when the evening come, the max i draw is 200w and then at night time( bed time) i draw 90w-100w till the morning when the sun comes out.

i must say this journey has been a wonderful one for me. I hardly on generator only when they want to grind in the evenings and that will be for like 20mins.

isangjohnson:
Please I need review on this inverter.

please run from this Ipowerx max.

the problem with it is that, it takes up to 30min-1hr before it start charging via mains supply. it is too sensitive and not rugged.
in my case within 24hrs of purchase it started showing code 09. Mosef don blow. please avoid it. go for other type of Ipower than this one.

The inverter has been bought and installed, the question is can it do remote monitoring.

Jefferyzz:
Stay away from yohako product. There are lots of substandard products under yohako umbrella, there no way u u can figure out the good one.
This features u mentioned is on growatt, powmr, felicity, srne etc n price is budget as well.

Good day people, please i want to find out if Yohako hybrid inverter especially the 3.5kva/24v has that feature of remote monitoring. I see it has a rs323 in the pack. i just want to be sure before proceeding to buy the wifi module.

Saipro:

I apologise, if the science statement rubbed off you the wrong way. I come from all 3 backgrounds. I merely believe your readers come from all walks of life. This thread began as a way to be a compendium/resource for all things to support the FTA rave of the time. Along the way, it became about all things renewable energy and the FTA aspect was relegated to the background.

I'll simply state what I had in mind. Peukert's law. You were talking about power equivalents thus a comparison of 12V 400AH vs 24V 200AH vs 48V 100AH is apt, being the same stored energy quantity. I₁V₁ = I₂V₂ = I₃V₃. It means one could draw the same amount of energy at lower current, if you raise the nominal voltage. In practical applications, the amount of power each is capable of delivering differs, as energy drawn varies due to discharge inefficiencies (mostly as a result of the internal resistance of the batteries vis a vis a resultant heating too). As a result, higher voltage systems would often perform more efficiently, as the amount of energy drawn increases. In practice, the upper limit of continuous discharge in a 12V system is about 6kW, beyond which you stand a real risk of melting the battery terminals or creating weird fluxes in the electrolyte (if FLA). Most conventional chargers don't exceed 120A thus limiting charge to an 1.8kW max anyway.

The resistance of the cabling matters just as much. This is why cable diameter and transmission distance matter! Multi-stranded chosen as superior to single strand.

My intention was not to waste anyone's time.

Bros the upper limit for a 12v system is 2KW beyond this is bad, while that of 24 is 4KW and that of 48v is 8KW.

What's your thoughts on Gel batteries everyone?
Good morning all.

To answer your question watch this youtube presentation
https://www.youtube.com/watch?v=a3PN1IjZFYs

temi4fash:


Is this applicable to GEL Batteries too?

Yes, but with slightly different values.

Drgreatone:
Pls which would be more efficient charge wise? 4 150watts paired to a pwm or 2 300watss paired to a mppt charge controller for a 12v 200ah battery?

i would want to say the PWM controller but go for the MPPT charge control for the sake of future upgrade and efficiency, you wouldn't miss it.

please can anyone suggest reliable non-hybrid wall mounted 5KVA/ 48v inverter and i need pointer to its technical data.

solareclips:
Please is it normal for a 24v tubular batteries that is 100% when there is sunlight or public utility but modestly after sunlight or public utility goes off, the power reduced to 85 or 75% , it will now depend on the loads before it will start to ho down.

Tubular batteries does what they call voltage sagging. It goes to fully charged at 27.1~ 27.5v floatation. After the sun goes out it start dropping to 25.3v (still fully charged) stays there for a while and when you put load on it, it further drops to 24.8v. it can say on 24.8v for hours depending on the load before it continues its voltage drop. So for a firm response what is your voltage at 75 or 85%?

abbeymighty:
Thank you, 2.5kva is mppt while 1.7 and 1kva are pwm

Thank you very much for the correction

brightk:
try to reduce your charging current. Check ur present charging current

I don't think you can change the charging current, what he needs to do it tune the generator up a bit for it to be able to charge.

abbeymighty:
Please can anyone give me review on affripower 2.5 kva hybrid , i used it with 3.5kva generator but it does not charge and we hardly have public utility.

I don't know much about the hybrid, the only thing I know is that it's not a MPPT charge controller but a PWM.
I use the 2.5kva non hybrid and I must say it is very rugged and durable.
