I want to buy Sumec Navigator NG2200 today. How good is the generator in terms of fuel consumption and durability. I need advice please.

Hailings engineer: i'm inquiring on behalf of a friend. Which gen can you suggest for her to buy. Gen should be able to comfortably power a freezer as well as a 1.5hp inverter ac. We saw a sumec firman 4kva gen for 200k but we're not sure if it can power an ac+freezer comfortably

Thanks and anticipating your reply.

The problem with ELEPAQ generator is that it has a lot of FAKE in the market and they're good in Exaggerating the generators KVA like a 2.5kva what you will see in the sticker will be SV4000, please if you want a good Generator that will serve you well go for SUMEC FIRMAN SPG4000E2 or ECO4990ES go for one of them, they are very strong and reliable.

Ojaysport:
Hello professor, I'm planning to buy an elepaq 3.5kva generator, when I got there, I discovered they're two types "constant and sehweh" elepaq constant is costlier than the sehweh. Pls is elepaq constant the best to buy or the other type is good as well? I'll be glad for your expert advice.

If you don't want a Lutian product,stick to original Sumec Firman or Haeir Thermocool products.

If you need the opinion of a generator technician,visit this thread

Prof, good day Sir. Sir, what do you think about Kemage?

I inspected a genuine Elepaq Constant Generator with a sticker that says it is rated 11kW and a Kemage Generator rated 8kW. Upon my inspection, I found out the Elepaq has a 390cc engine while the Kemage has a 490cc engine. I also found out that the coil of the Kemage was way fuller and longer than that of the Elepaq. Also, the Kemage weighed more without accessories despite having a lesser frame than the Elepaq.

What do you think?

Post your issue on this thread -- https://www.nairaland.com/2335449/professor-type-generator -- for expert help.

That said, my advice would be to return it and get a replacement as it should still be under warranty. It's completely normal for some units to be defective; there's no perfect assembly line.

With standard moderate usage, an original Lutian gen should last 1 year plus before you even remember to service it.

I experience this most times. The oil doesn't last more than one week before changing it. Secondly, my relation bought fireman sumec rugged. What can it power effectively?

I need some help here.

I have an Elemax 6.5kva Gen I have been using since 2016 but recently our transformer broke down and I was forced to buy Sumec Fireman 3000e2 to save fuel since the Elemax was gulping like 2.5 litres every 1 hour. It is a 2.5kva Gen and I noticed it consumes like 1 litre of fuel per hour. The load on the Gen is usually around 1kva whenever I use it.

I want to know if there is anything I can do to improve the fuel efficiency of this Sumec since I purely bought it to save money on fuel.

Your help will be greatly appreciated.

Hello Professor, Thank you very much for your offer to help people here!

I am an Engineer in USA and I am helping a Nigerian Engineer design a phone remote start-stop for generators. He has a Firman SPG3000E2 and we are trying to understand the engine wiring. Can you tell us where we could see the electrical diagram for this unit or a similar Firman generator?

It is difficult to advise him when I am far away. He is a good Engineer and he has things somewhat working but he needs to be able to make sure things are wired correctly. Also he would like to be able to do similar controls for other generators.

Please tell me how we may find this diagram / information..

Regards, Terry King in Vermont USA terry@terryking.us

How much can I get the spg4000E2?

toxicbrain:


Can this SPG 4000 carry a 1200W iron and 750w 1 phase industrial motor?

Debignony:

Hello Prof, I took your advice on getting a more popular brand that I can easily get the spare parts. So I got SUMEC SPG2200, hope it will serve me well?

DazzyOfficial54:
Hello professor,good day
Prof I made some necessary investigations about your reply on the question I asked about constant elepaq,and found out there is sense in what you said,thanks..... I bought this SPG4000E2,,For my younger brother who stays in my village home,he is a Barber.... The load he is using on this generator is not up to 1kva whereas the generator is like 2.8 - 3kva,so I would love to know weather it would affect the work rate of the generator...

Abosede2020:
Hello prof thanks for your prompt answer to my question the other day. Please I want to know if Power Value is the same as Sumec Firman. That's what I was told because it is in almost every Generator shop in Ilorin and it has the same Frame with Sumec Firman. Although it is cheaper they said everything about it is the same with Sumec Firman.

Olebunne94:

Nnadozie20:

Jamaxema35:
Hello professor

I have bought the AC6000E2, thanks for your advice. I would like to know the space of time to change oil? So as it would last long, the seller gave me a space of 1 to 2 months... Thanks

afoluwato:
Hello Prof. Where can I get original battery for my 6KVA generator? I have given technicians money to buy for me but they keep buying fake ones for me. I don't mind a location in Lagos. Thanks
