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.
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
earthrealm: plenty annoying problems, kpele....., below in green are some of my thoughts on the issues, you had
Battery was always showing 100% on the app even when the voltage drops to about 25v or below.
Also, total power generation is always showing 0.00kwh on the App. You can imagine that I paid 30k extra for the wifi dongle.
On the inverter display screen amp charging the battery is greater than the power generated from the solar panels.
After switching off all load from inverter and no PV power is coming in( night), the fan does not stop working.
Once you put a load like electric kettle, microwave or cooker of abt 1.2kw on it, the load in kilowatt can fluctuate from almost zero to 1.8kw.
When you put 2 of those load on it, the inverter switches off. I guess overload due to fluctuation. I guess the inverter was over rated to 3.5kw
Many other issues I can't even remember.
earthrealm: OK, YES, THIS ISNT THE SOROTEC FLAGSHIP MODEL WITH TOUCHSCREEN DISPLAY. this is the vm ii, one of their budget models. sorotec has been in existence for 15yrs---am sure they would have folded and closed shop, if they are known for churning out wonky products
endless problems,, would be great if you can share a few of the problems........perhaps 2 or 3 for starters
My revo vm ii pro. See pics. The list of the inverters problem were endless. I was not shocked when it finally gave up the ghost
earthrealm: Post a picture of the particular Sorotec model, lets see. I am a fan of Sorotec and premature failure by unknown causes isnt among its known faults.
Revo ii is their flagship brand and quite reliable.confirm this is yours
Maybe, Sorotec use to make them good. When I bought my, the Sorotec logo was poorly printed on the inverter casing. I had to send the picture of the inverter & logo on it to Sorotec & they confirmed the inverter was made by them. It only worked for abt 4 months & died. I had to replace it with Felicity. Atleast, if anything happens to it within warranty, Felicity will take responsibility & repair it. That can not be said of Sorotec
earthrealm: Do enumerate please, so we can all learn Hv 3 units running for over 2yrs now
You should have bought the RCCB or RCBO type A and not type AC. RCCB type AC have been discontinued in most western countries because if electrical circuit is saturated with DC milliamps, RCCB type AC may not work well or trip when it should. Most of our electronics feed our electrical circuit with DC milliamps. RCCB type AC will only work well if it is dedicated to an appliance that has no electronics in it, eg regular water heater, electric kettle.
Good day Sentio. I tried googling the company that plans to build such a massive property and the don't seem to exist or have a website. Who is or are the owners of the company. What is there track record. Have they carried out similar project and delivered on time. Answers to these and many other questions will give potential investors confidence
Check the average super market, you will likely find one with lower power consumption. I have personally seen a 1.5liters electric kettle with 1300w power consumption on it. I wanted to buy it but my wife suggested we go for 1.8liters/1450w.
isangjohnson: I tested 1600w qasa electric kettle today with nepa light. Though I didn't check the litre but the water was boiled at exactly 8 minutes. I want to buy and be using it for day and night on solar. Does anyone know another product with lower watt? Night consumption is my little concern, though my battery bank is sufficient for such load.
If a 1.5hp pump is drawing 1.8kw for its regular run then it is either ancient or inefficient or falsely labelled (should have a higher hp value stuck on for the duty cycle it can actually handle)
Dear Niyi, the power consumption of submersible pumpd Earthrealm stated is what most of us see everyday. My 1.5 HP gulps btw 1700w to 1800w. Initially, power consumption was btw 2000w to 2200w. I had to double the size of the cable to 5mm2 before power consumption dropped to 1700w to 1800w. You should also know this, most of us buy the Chinese pumps. The efficiency of this categories of pumps are low. Only very few people buy the very expensive pumps made in Germany or Italy. Just the same way, only very few people buy Victron. So Oga Niyi, the power consumption Earthrealm mentioned a while back is the reality of most of us.
Report them to FCCPC (Federal Competition and Consumer Protection Council). Its a federal government agency. They can help mediate & resolve the issue.
How to report a complaint to the FCCPC The FCCPC has set up an online form for consumers who want to make a complaint about a company.

If you are not comfortable completing an online form, and would need to talk the complaint through first, then the CPC has dedicated customer complaint lines which you can call. You may contact them on 08056002020, 08056003030, or by email on : contact@fccpc.gov.ng
I want to warn members and the general public from buying from energymall.ng especially solar panels. [img][/img] I bought 4 units of 350w solar panels at 77,000 each for a total of N308,000. They showed me the original Felicity panel as sample and then shipped me fake 180w panels. I hope those panels are up to 180 sef.
Find picture of said fake panel nameplate below. All effort to reach them after has proven abortive.
It’s difficult doing business in Nigeria if people are looking to rip you off at any chance that they get. If only someone had posted their experience online, I wouldn’t have fallen victim.
Please do not buy from energymall.ng they will scam you
Thank you Adrusa. I will reach out to you when am ready to install FCC
adrusa: I don't know what your setup is like. It may be difficult starting from scratch, but for me, it was easy because I already had all the ingredients; a raspberry pi running Raspberry OS, the necessary cable and home assistant with utility integration helping me to sum up the daily harvest. You can also use emoncms or pvoutput if that is your thing.
I started with this code on GitHub. https://github.com/solarsnoop/PCM60X-Monitor. I then stripped it down to remove the http part. So, I ended up with a json array which I feed into nodered which then splits them up and gives me what I need. You can use MQTT if that works for you. I then feed the power into Home Assistant which does the daily summation.
Some people may suggest that you should just get a CC that does the summation without going through the trouble, but that won't necessarily work for me because I will still need to get the figure out of the CC and feed it into my system. I don't have to go the CC to see what I generated at any instant.
I can share my codes with you if you have a similar setup. No need to reinvent the wheel. FCC stands for Felicity Charge Controller
Good day Adrusa, kindly share how you did this. Thanks
adrusa: I also have a Felicity CC in action and I'm okay with it. The only problem is that it doesn't show daily harvest. I have gone round that with a data cable and a system that calculate the daily harvest from instant power. So, nothing do Felicity CC.
Dear Odimbannamdi, different company will make/design there inverter differently. My mother's Schneider inverter while switched off display this light(see the first picture). The source of the power of the light is not spiritual but from the battery. See the second picture while the same inverter was switched on. What Dam5reey said is true & valid for some inverter.
From his experiment, he has just debunked the emphatic position you took yesterday that an inverter that is SWITCHED OFF consumes power/energy continuously. Also, it is now clear that you were mixing up "idle state" with "No Load state" yesterday.
We hope you can take the same correction you wanted someone else to take yesterday.
Anyways, each time I come here to read posts, I do with an open mind and a learner's mindset. Ready to learn and take corrections coz I hold everyone here in high esteem. I encourage everyone here to do the same as well so that we can all learn.
Just Emmanuel, you are a disappointment to yourself & business. You came to Nairaland to lambast me while on whatsapp you are begging me. Shame on you. As for the Schneider Inverter, that's what I wanted to buy but you where trying to sweet talk to buy another brand which I refused. Immediately, I called Kiekie & I bought 2 from him. How did I complain. Like I said, shame on you Just Emmanuel
justcallmenuel: You’ve always been a complainant right from the first time you chatted me up for 1.5kva 24v Schneider inverter (08-01-20), I should’ve listened to my instinct and not do business with you. If you think you can destroy the good name I’ve built for years on this forum, you lie bro. Stay safe and enjoy your Sunday
Just Emmanuel have been advertising LG inverter ac for sale. I bought 2 from him, only to realize that this AC's are not made by LG and they don't have inverter compressor. See the the pictures below. The company that manufactured the AC is called LGEFF Electronics. I tried googling about this company and came up with nothing. After installing it, the AC behaved exactly like the normal AC with a normal surge. The LG logo print on the AC is poorly done. Each time I compare these AC's with the ones I bought from LG outlet(Fouani), there is a world of difference. I wasted money. I would have bought Hisense inverter AC for the same price. I called just Emmanuel and told him about all my observation, he was insisting the AC is made by LG & it has inverter compressor. I also bought 10mm2 PV cable from him at a very cheap price, only to discover that, it's not 10mm2 but somewhere btw 6mm2 & 8mm2. Olopan can bear witness. I personally will never have any dealing with Just Emmanuel.

Buy Century Stabilizer, though your out put maybe around 160v to 170v if input is 65v
Peterlove11: Which is better servo or relay stabilizer....the voltage in my house could be as low as 65v sometimes, simply unusable. Which should I go for?. Needs one urgently. Thanks
My mum have a 48v, 3.5kva Sukam inverter which she retired after 2 yrs because she could not afford to replace all 4 batteries when they died. She is currently using a 24v inverter bought from Kiekie. I am interested in the exchange
adrusa: I have a perfectly working 4-year old 24v outback inverter (VFX-3024E) that I will like to exchange for a 48V variety or another good inverter or sell for cash if I get a reasonable offer. I also have a mate 3 I can sell at a reasonable price.
tonididdy: Thanks but sadly I am confused even further. I give up, am just worried a system I setup for 200k should last long. I have a feeling the installer just zapped in and out hurriedly. Please if any DIY NL is in Benin city, please chat me up.
Good day Kiekie, kindly let me know the idle power, max surge power & continuous running watt of the Schneider homaya1500va. Also, does it have voltage selector? Am interested.
Search for Thundervolt on Jumia or Konga. There 24v, 1.5kva comes with a 30amp Fangpusun MPPT charge controller (110k) which is one I am currently using. The 120k version, is also a 24v, 1.5kva that comes with 50amp MPPT charge controller
Andreda1st: Really!!! Do you know if I can get something similar with a higher mppt charge controller at that price?
GeorgeD1: here's a rough depiction of what i have on ground. please never mind the hand drawing. replicate that in 3 places to represent each of the three strings and connect each string to a single bus bar. so i have 3 positive cables and three negative cables connected to my inverter through the bus bar. and very importantly, each cable having equal length regardless of distance from battery bank. so essentially, it's three independent banks operating as one. same charge current, same discharge current from each string. hope this helps?
Good day Oga George, kindly share the pictorial diagram of your battery connection. I am amazed you don't use battery balancer.
GeorgeD1: niyi, you're very much on point. in the early days of my renewables journey, i did some extensive research on various methods of battery connections in a bank and the method i finally adopted was ranked among the best. that, along with my oversized solar array has ensured that my batteries remain in top shape these many years, beating even the most enthusiastic predictions. and, it's also the reason why i don't use a balancer despite having three parallel strings in my bank.
Good da Distech, I am interested in buying some of your type of batteries if it is still available
Dishtech: For I have small package like that, 2 used 40ah LiFePo4 battery (10k each), 250watt solar panel (33k) 40A pwn charge controller ordered from China (6.5k) and a homemade inverter made by my self (7k), cable (3k) TOTAL #69,500. This power my 32" Led TV, home theater, decoder, my standing fan, charge my phones, and 4 Led bulbs. Am usually home from 7pm which my appliances comes on then, till 11:30pm or 12am bed time TV is off leaving light and fan till 3 or 4am when weather is cold fan is off leaving light till day break. If am home I equally use the system when battery is charged from noon and the system is running smoothly for 6 months going. Below are my setup!
Dear Adrusa, Kindly link me up with your local Installer. Thanks in advance
adrusa: That is largely true and it is because many "dealers" here are just middle men trying to make a living on enthusiasts who don't want to go to the market. I almost paid for 300W flame solar panels here until my local installer got them for me from Alaba for about 10K lower. What they do is to advertise goods in other people's shops as their own. It is the reason why they also try to put people under pressure to pay fast as the "stock is small". I personally would have preferred that this place is reserved for hobbyists and enthusiasts while marketers and middle men set up their own thread.
