Please how much was the shipping of the inverter to Nigeria. Was there any custom duty paid? I intend making an order either on Aliexpress or Alibaba for a 48v 3.5kva inverter. I really need help from anyone that recently made a purchase from either of these platform

Yes i have just ordered for extra 8 batteries, but my issue is the promised fast shipping for charging me excessively don turn to delay o

What is the make and model of this inverter?.
No normal inverter outputs these above normal voltages, i wud even be wary of exposing my electronics to 265volts, not to talk of 290volts
I think these voltages are input voltages, not output.

You should use a dmm and measure the output of the inverter to be sure of these output voltages you posted

Homaya 1.5KVA

Maybe these are input voltages, but if they are input why tell me not to use computers and sensitive equipment on ECO mode

I will act on your advice and use a DMM to measure the output voltages and report back

You may be misreading your inverter manual.

ECO mode does not take longer to discharge the battery - it is talking about the mains input AC voltage tolerance - in ECO mode your inverter will allow voltage from PHCN or Gen between approx 90 - 300v to pass through to your loads.

In UPS mode, your inverter will allow mains voltage from PHCN or Gen from approx 170v - 275v to pass through to your loads. Also the transfer time in case of mains failure is shorter so that your sensitive equipment e.g computer does not reboot.

It is clear that these basic inverters offer scant protection to your equipment or loads at the voltage levels they allow to pass through - it is always best to install voltage protection at the input side of your inverter and set a threshold between 180v - 248v.

From above 265v you should witness light bulbs going pop and circuits running hot/burning out, I also don't think motor windings like to be fed too high a voltage.

FEGEITOK:


My inverter has 2 modes ECO and UPS.

ECO Mains high cut 290V +/- 10V
ECO Mains high cut recovery 280V +/- 10V
ECO Mains low cut 100V +/- 10V
ECO Mains low cut recovery 110V +/- 10V

ECO takes longer to discharge but has a range that hits 290 Volts

UPS discharges faster but has a safer range of not more than 265 Volts

UPS Mains high cut 265V +/- 10V
UPS Mains high cut recovery 255V +/- 10V
UPS Mains low cut 180V +/- 10V
UPS Mains low cut recovery 190V +/- 10V

Says to use UPS mode to run computers/sensitive equipment.

Says not to use ECO mode to run computers.

I am running computers on the inverter, but I don't wish to fry them.

ECO mode is the default mode.

I want to take advantage of the ECO mode but limit the risk to my equipment.

Thanks for this extra information.

I have been using this inverter for some 7 months and after this trial run, I want to get the Conext inverter which is superior I hope in protection as it is in load carrying capacity.

Please recommend voltage protection for me. Is it the stabilizer or is it a surge arrestor or both?

If yes, then appropriate capacity of each one if both or one or the other if just one of the two as well.

Thanks again.

hello everyone,

I am stil trying to get my feet on this solar thing.. today i used a pv meter to check on a panel (africell rated as 300w) . I got a shocking 110w 22v, 4.89 amps.. I have four panel that was first connected by a friend and according to him it was done in parallel. I am using an epever mppt controller 100v 30a.. before now i couldnt generate more dan 280w from this four set of panels my setup is a 4.8kwh litium battery with a 24v 1.5kva scheinder (homaya) hybrid inverter.

Today i decided to connect 2 panel in series and parallel both strings together...

I was able to get 44 to 50v of peak hours with current raning from 5 to 9amps today...

My question is why the low output from this panels....

How are things now?

I will act on your advice and use a DMM to measure the output voltages and report back

Its a normal warning on luminous, simba and other low end inverters.
The have a switch at the back normal and ups.
The significant difference in the output between the 2 modes is transfer time <10s3cs for ups and greater than 10s3cs for normal/eco...
What this means is if you are on nepa and nepa goes, the inverter transfers from pass thru to inverter mode, this transfer takes some time...which sensitive equipment like computer can detect and go off, but the human eye is unable to detect this.

Well built and Mid to high range inverters usually have ultra short transfer times...so this warning is irrelevant

brother,
this inverter specs is totally at variance with the norm and its a disaster waiting to happen.
i will advice you discontinue any further use until you have the funds to purchase a replacement.
what you're toying with right now is a potential multiple damage to your electronics as well as a
fire hazard. i think the engineers who designed such a derelict product need to have their heads
examined. a word is enough...

In the interim, he can deploy appropriately sized AVR between grid and input; or some voltage/current limiting device as alternative - while he source for a better inverter.

If the grid is always normal, you can do without those, but you can't bank on this.

Thank you very much for your concern.

The issue now is to determine an appropriately sized AVR to act as an in-between the inverter and the grid

If I didn't ask questions, I would never have known that when you buy the cheaper inverters, that you don't get all the protection of the expensive variants.

I am sure others are learning as well.

When it says 1.5 KVA, does that mean that I have to get an AVR greater in capacity than 1.5 KVA?

Yea, you should. 2KVA will do.

Meanwhile, the AVR needs to be a good one and in good condition because I have seen AVRs pass excess voltage as received.

My brother, I used to see 18 or more hours of grid power.

But this year, things changed.

Alternative power supply is no longer a luxury but a necessity.

I don't want to talk about the fact that buying fuel in jerrycans at petrol stations is now considered a crime but buying the same fuel in jerrycans from black market suppliers on the street is legal activity.

I therefore had no choice but to make alternative power arrangements, and now that I have seen some spare cash, I better improve my alternative power generating capabilities.

Given the way the government and the power companies keep increasing the cost of power, I believe in the end, this project will pay for itself and reduce my dependence on outside sources for a key input for my production.

I am following in your footsteps, and that is why I asked you about your experience a few days ago because I have fallen in love with the brand.

FEGEITOK:


Alternative power supply is no longer a luxury but a necessity.

I agree with you, it's now a necessity to own a backup power as the government do not care about power for the masses.

Hi. My inverter doesn't charge my 200a 12v Lifepo4 battery efficiently. In the manual it states it's has 80a solar charger and pv input is 90-450vdc. My pv input is mostly between 126vdc to 131. The inverter at times will just stop charging and will b blinking the panel symbol.. inside hot sun at times my bms shows 12a going into my Lifepo4 cells while the inverter is not under any load. Im using 3 400w panels connected in series. My pv connection is good and intact.

Have you considered getting a Deye 8kw inverter.
Specs are much better than the XW and has features that are extra cost on the XW.

How do I know d inbuilt cc is mppt and not pwm? And if at all it was "mppt", how am I so sure it is a true amp rating?

SO THIS YOUR INVERTER IS 12V MODEL?..u should have snapped the side, showing the specs..most high voltage hybrid inverters, their sweet spot is about 270 volts, the Voc of the avg 400 watts panel is 43 volts , so you need to increase your panel to 7 panels in series, wch wud be massive for your puny 12 volts 200 ah bank ----it appears u didnt do any serious research b4 setting up this your systenm.

all is not lost.you cab either look for a decentmppt standalone charge controller... ...and connect the 3 panels to it

I will suggest you buy a solar cc separate to charge the battery and do your panels in parallel becos ur panel voc is far higher than ur battery nominal 12v. so by this, you will have higher current to charge ur battery. the new mppt (e.g powmr) will help balance the excess voltage with current for use under load.

Yh. I'm planning on getting this. Which charger controller under 100k that can handle 130vdc do you recommend.
