You abused the inverter. You didn't interpret its data sheet well and you do not understand some things about electricity.
Learn about:
Surge or startup power: Freezer goes on and off at intervals, at startup is draws up to more than 5 times its rated power.
Power factor: a 1kw load may draw 1.2kva. Inverter is rated 3.5kw at power factor of 1
Temerature: derating: at higher temperature total power draw should be reduced.
Voltage deratinng: if you're connected to mains and its available, you should derate load below 170V. Mains supply in some places can go lower than 150V in Nigeria
As Niyi put it, HF inverter is more prone to damage than LF inverter but more efficient. My old retired HF inverter (cyberpower) does not do more than 2.5kw even though it's rated 3.5kva

My reply to your suggestions or questions;

1, App issue, perhaps tried uninstall and reinstall, or another app?

I abandoned the inverter. I now use Felicity and it's working as it should. Mind you, it's about 100k cheaper. Though, Felicity is 24v 3kw, MPPT 100a while Sorotec is 24v 3.5kw, MPPT 100a.

2, You said amps, not watts, hope you know for mppt, 3amps 389v might be coming in from panels, and the mppt will change it to 15amps, 56v?

Imagine 1500w coming in from solar panels & inverter is shows it's using 70a to charge battery.

3, Might be an issue unique to your particular device, or perhaps you didn't wait long enough perhaps up to 5mins, mine doesn't behave like this.

There was a day, I had to wait for about 2hrs after load has been switched off and the fan is working like I loaded to 80%.

4, Yes, the load meter on most budget inverters are not very accurate.

Well, I bought the inverter because seller told me Sorotec build there inverters with quality components.

5, What size and type of battery do you have to load 2 electric kettles on your setup?

24v 15kwh, lifpo4

6, Most invertes get more inefficient as you are loading it towards the max capacity, and this is worse on budget inverters. 2ndly it might even be your battery sagging and tripping the LVD, if you are using leadacid batts or the bms cutting off if you are using lifepo4 battery etc, did you observe your battery voltage b4 the inverter turns off?

I have a Tomzn voltage/current protective devise connected to my setup. Max 2500w load is allowed. Anything above, the device will trip off. If inverter is rated 3500w & I occasionally do close to 2500w. I still have a gap of 1000w. I am no where near the max capacity of inverter. Battery is 24v 15kwh, so it has nothing to do with the battery.

The day the inverter died with a loud bang, LG 1.5hp inverter compressor AC & Thermocool 219 liters (not exactly sure) freezer were the loads on it.

Bottom line is, inverter is poorly built. Probably built for Bangladeshi market

I DEcided not to comment again on the sorotec inverter isssh, am not the owner of sorotec, neither am i a part owner, nor does sorotec pay my bills in anyway, so he is free to port to any other inverter model that gives him joy---though am certain most low end HF inverters would also fail if subjected to the loads he described. Sorotec unfortunately only has a 1yr waranty and due to difficulties in tracking claims, this waranty is tied to the date of manufacture on the body of the inverter.

growatt cost almost twice as much as sorotec\, and have an office in nigeria, but they footdrag and delay when it comes to waranty claims and repairs.
felicity also has an office in nigeria, and from what i have heard, have better waranty claims turn around period.

Hmmm. Sorotec. I have a 5.5kw unit (bought late last year) acting up. Displaying error 32. Manual says it's a communication failure between inverter and remote display. It will not connect to battery and when switched on by solar imput, will temporary display no battery mode before bringing out the error.
I had to put back my backup 5kw Gennex while waiting for the resolution.
My battery is 12kwh LiFePo4 and connected to the battery through positive and negative power cables only.

Felicity is good....they honor warranty, and there inverter is strong. I have been using their 5kva hybrid going to 2 years 24/7. I cook daily with it, iron, pump water,microwave and power my whole flat with it. It's reliable. It might not have the bell and whistles of expensive inverter brand but it works

NiyiOmolyunde, I mentioned 1.5hp LG INVERTER compressor AC. There is no surge. I always use the GEN MODE. At this point, I can say, the AC is working like a 1 HP inverter compressor AC. See what I initially typed;

The day the inverter died with a loud bang, LG 1.5hp inverter compressor AC & Thermocool 219 liters (not exactly sure) freezer were the loads on it.

NiyiOmoIyunade:
Ah! 1.5hp AC on a 3.5kw 24v HF transformer based inverter is plenty o

As you may know the HF inverters do not like inductive loads - they have virtually zero surge handling and what they do have is usually for 1 or 2 cycles - read like much less than half a second - although you may have an inverter AC, the variable speed motor will still present an inductive load. The physics limitations of switch mode power supplies must be respected as in an HF inverter lacking a large iron core/toroidal transformer they perforce cannot handle the surges and transients created as inductive loads go on and off (when your AC compressor picks up or cuts off). The ability of your inverter to handle surges and transients is directly proportional to the amount of iron present in the transformer due to something called the 'flywheel effect' . LF transformer based inverters rated for large loads have plenty of iron (more than needed for the application) in their transformers and the FETs switch much slower (hence low freq) and are often large sized and designed to run much cooler - all these factors surges/voltage spikes & transients/ back emf/reverse current/flywheel effect running temps etc impact how well your inverter does with surge loads.

In simple English most budget HF inverters are sorely lacking in the internals needed to run those large and problematic loads robustly for a long time.

There is also the issue of large loads on a 24v system - it is amps flow that makes cables and power electronics heat up which is why you may have seen your fan run more than you expected.

2,000w load on your 24v nominal LFP bank is 75a flowing through the inverter DC bus - even in a premium system 75a is significant energy flow talk less of a budget el cheapo with lower grade components.

I think you may have pushed the device beyond it's real hardware limits. It is not uncommon for the capacities and tolerances of el cheapos to be overstated.

Dear Mankind, how come all of you suddenly did not see that the AC is LG inverter compressor AC. Where is the surge coming from? Now imagine me using it on GEN MODE.
See my original comment;

The day the inverter died with a loud bang, LG 1.5hp inverter compressor AC & Thermocool 219 liters (not exactly sure) freezer were the loads on it.

mank1234:


I was even thinking it's a 5kw inverter the guys is loading a 1.5hp ac and freezer. Freezer alone has 5x to 10x starting power draw ( for a 150w freezer, that's like 700w to 1.5kw.
1.5hp ac is draws about 1.6kw to 2kw.
I'm pretty sure other minor loads were on - like light and fan.
It's insane to expect 3 5kw output from a 3.5jw inverter rated to just 5s at 105% load. It mean at 100%, it may just be less than 15min. Better inverters are rated to say 110% continuous load.

Again, he didn't even consider power factor of those loads.

Mankind 1234, total load of 1.5hp inverter compressor AC used on GEN MODE & a 219liters Thermocool freezer should be less than 2000w (plus freezer surge). How did I abuse it? If a so called well built inverter can not handle a load of abt 2000w out of the rated 3500 inverter capacity, re u saying I should only power LED bubs & DC fans?

Another solid battery brand with good warranty especially for Tubular Lead acid batteries. Better than Luminous in my opinion. They have authorized resellers across the country you can buy from and provide support/warranty issues. But don't forget that Tubular batteries don't like to be discharged beyond 50% of their capacity and need periodic maintenance (electrolytes). https://eastmannigeria.com/

I understand your plight and I believe you are right with been unsatisfied with sorotec. It seems these axpert clones apart from maybe growatt/felicity have same issue of unreliability. I have a 3kva ipowerplus which is an axpert inverter and occasionally run a freezer, 1.5hp inverter ac and fridge and nothing happened. Said inverter was bought 2018 and was retired after a thunder strike late last year, I bought exactly same inverter again and currently enjoying it. A simple Google search will reveal the unreliability of these axpert clones. There's even a decidated thread on it. It's a pity a known brand like sorotec will slap their name on those clones because I'm sure those inverter were not produced in house and therefore not as robust as their other models. I assisted a friend in getting such a clone because it has his desired capacity(3.5kva) and inverter didn't even last up to 6 months, now he has lost interest in HF inverters as it couldn't be repaired. These clones are hit or miss

Hello, I also have the ipowerplus 3KVA 24V inverter I've been using siince 2016 and still running strong.
It's my ipowerplus batteries that are now weak and I intend replacing them with a 24V Lithium battery.

Pls What battery do you use and can the ipowerplus inverter charge a lithium battery?

It's good to know that you have a user experience of using your inverter to power your inverter A.C occasionally as I have been contemplating doing so with mine when I get the new battery.

80k or 800k

Sorry, 800k.

I read you correctly boss about what type of AC you use(d). You quoted me but neglected to read what I actually wrote and I have now bolded below.

Without going too technical, your inverter AC uses a VFD to achieve energy savings and some pf efficiency by regulating the compressor motor speed - this process involves taking AC from the mains, rectifying to DC and then inverting back to a different AC waveform to drive the compressor motor.

The workings of the VFD (inverter drive) create voltage spikes/transients/back emf and harmonic distortions which your HF inverter is very ill equipped to handle - it is not just a question of the load wattage your Sorotec saw, but all the noise and distortions and faults and transients generated in the power line as the VFD ran. In fact you may have been better off with a standard 1hp AC mated to the Sorotec.

Beyond the technicals above, it is common for el cheapos to have capacity overstated - they may well use the surge capacity as the running capacity of the machine. Also temperature derating when you use the inverter in a non climate controlled room is a thing.

You already took your loss so let me not belabour the point, all these are for other users to be guided - it is best with el cheapo products to load conservatively say a max of 50% including surge i.e your peak load including spikes should stay well within 50% of the advertised running capacity - only go more aggressive if you have verified your particular machine to be built for that duty cycle.

Bus on the BMS, the battery's BMS uses same wire for charge and discharge

You will need an external LVD device that does the job for you, that way you won't have issue waking up the battery.

Okay, thank you 🙏

Please, is electrolytes the same as distilled water?

Good morning house. Please what is the recommended float voltage for a 12v gel battery?

abbey086:

Please, is electrolytes the same as distilled water?

Nope, electrolyte is water that has already been mixed with acid.----you should never add this to a flooded battery in use, as it will distort the acid-water balance, making the electrolyte too acidic.
And corrode the cells inside...leading to premature battery death.

You should only add distilled water to a flooded battery already in use
