Gptech:

Buy from accredited stores only and for the case of Sumec firman, there are guides on their site to check for fakes.

Thanks sir. Think I will like elepaq kind of

Why didn't you consult here before going for a Senwei? I do advice against getting a Senwei.

Really man, I didn’t know :, I just stumbled on this forum while searching for solutions to my generator not starting

KEY POINTS BETWEEN RELAY & SERVO STABILIZER

AVRs (Automatic Voltage Regulators) or Voltage stabilizers have become something of great importance to every family and business alike to help protect electrical equipment from irregular current coming in from the national power grid. These AVRs helps to regulate the voltage supplied from the national grid such that it will deliver the required amount of voltage required for the family or business equipment if the incoming voltage is within what the AVR can regulate.

The production of this Stabilizers started with the use of an electromagnetic relay system that helps in selecting the right part to adjust the incoming voltage. This method came with its own strength and weakness. Later, another method was designed with the use of electronic circuit for the adjustment purpose. This method also comes with its own strength and weakness.

The initial technology that is also used for the production of Stabilizer is called the relay technology while the other technology is called the servo.



Relay Voltage Stabilizers / AVRs (Automatic Voltage Regulators):
With the relay technology in stabilizer, the electronic circuit inside the stabilizer compares the output voltage with a reference value that has been provided and built-in to reference voltage source.

Anytime the incoming voltage goes higher or lower than normal, the control circuit switches in the Stabilizer switches to the corresponding relay to connect a desired tapping for the output voltage. The relay technology comes with a ±10 % output voltage accuracy.

This type of stabilizer is mostly used for low rating appliances in homes, offices and industries as they are of low weight and low cost.

However, this technology comes with certain limitations which includes low voltage correction speed, less durable, less reliable, among other issues in the stabilizer technology.

At the same time, researcher has developed a later technology for the stabilizer and this is called the servo controlled system. This technology attempts to resolve the accuracy of output and the delay time in the relay technology of stabilizers.



Servo Voltage Stabilizers:
The Servo voltage stabilizer consists of the servo motor, Buck Boost transformer (BBT) and Autotransformer among other elements. The voltage that comes out of the servo stabilizer is voltage across the Buck Boost transformer (BBT). One end of the primary BBT is connected to fixed tap of autotransformer and the other end is connected to the shaft of the servo motor.

Whenever the incoming voltage is too high or very low within the input range, the servo motor in this servo type of stabilizer moves across the autotransformer in such a way that the voltage induced across the secondary BBT is equals to set output voltage.

This type of stabilizer is called a servo stabilizer because it uses a servo motor to enable the voltage correction.

Servo voltage stabilizers have a rugged construction and can sustain high fluctuation and it is more durable. It is mainly used for high output voltage accuracy, usually ±1 % with input voltage changes up to ± 50 %.

If we compare servo stabilizers with relay type stabilizers we can find various advantages of servo voltage stabilizer such as higher correction speed, high precision of stabilized output, capable of withstanding inrush currents and most importantly the high reliability.

SERVO STABILIZER ! :

-Servo motor is used for controlling unit of voltage level.

-Level of protection is high.

-Servo motor has good step size resolution for correction of voltage.

-It will give balanced output which may be ±1% error.

-It is available for higher rating more than 1 KVA.

-This stabilizer can be used in the industries as well as at homes.

-Cost of servo motor is more than relay.

-This stabilizer is used in the communication line.

RELAY STABILIZER !


-Relay is used for controlling the voltage level.

-Relay has lower size of resolution.

-It will not give stabilized output with accuracy.

-It is for low rating.

-This stabilizer can be used at homes.

-Cost of relay is lesser than servo motor.

-Level of protection is low as compared to servo type.

-This Stabilizer is basically used in home or for small scale purpose.

Thanks sir. Think I will like elepaq kind of

If you can get an original it's good, na fake plenty pass for Elepaq these days.

These days what you'll likely see in the market is Elepaq Constant. Hence, watch out for an engraved CONSTANT on eight basic components which are listed as follows:

Oil Tank
AVR
Air Filter
Engine Block
Alternator Rear Frame
Muffler
Carburetor
Cylinder Head Cover

Hello everyone.
I use a sumec firman spg3000. Of late, it goes off by itself aft 30minutes to 1 hour usage. It just trips off like someone put it off. I've cleaned the plug n air filter but the problem still persists. What could be the cause and the solution pls. Thanks

Check the oil level, if it's down fill it up. You may need to change oil.

Thanks chairman. But I recently changed the oil too. Like 9-10 days ago.
Although I recently bought a new sewing machine that requires the motor to run continiously without stopping unless I stop it, more like a ceiling fan. It's a 400W induction motor. N I notice the first time I used it with the gen, it almost went off but it picked it. Aft that day, no problem, I even used that machine for hours. Everything went fine till yesterday.

Hello brothers,

Please I am using an Elepaq generator and I noticed that it consumes alot of oil, what can I do to reduce the oil consumption.

And what us the best brand of oil to use

Good morning @enochogaga, other generator proposals in the house. My generator keeps burning the AVR. It burns the avr almost within a month. What could be the issue, pls?

Thanks Somuch.

How many hours do you run your generator daily? If you run your generator 24 hours everyday, you'll need to be changing the oil within 3 days.

Hello house

There is scarcity of Tec junior in Lagos as I have gone to most stores. I'm thinking of replacing my search with Sumec 1800 PRO MAX. Is that a good Choice?.. considering tv, fan, laptop, water dispenser, power saving bulbs, console

Any idea of where to get that Tec junior now I will appreciate, its my first choice

Jaiiis:


Will the 1.5 carry my fridge and blender? Even if it means I have to turn one off for the other. And say if I get a TV in future (I don't know why I would tho) will it be able to hold the TV and the fridge?

I have a sumec firman 1.1kva generator that powers my TV, LG 1000 Watts dvd sound system, 2 fans, inside and outside lights. I sometimes use it to blend my groceries too, without stress. I've been using it like that for the past 6 years without any issues or problems. What matters most is I regularly service it and use the recommended branded oil, not the road side oils. Hence that 1.5 is good to go. Just buy it from a reputable dealer. I'm currently planning to upgrade to a bigger gen make the old gen retire , I want to get a 1.5hp ac and I need something to power my fridge. A Tec 2.2kva will deliver.

Try jumia or konga. Thermocool has there products on display with even discounts on konga. U don't need to worry about the genuineness, it's straight from their warehouse and has the normal warranty that is common with tec products.

For that 1.5hp AC, you should be looking at a 3.5kva generator, and it will be better if the AC is the inverter type.

Please I need review on Maxi Generator, is it worth it?

Please tell me why plus the pros and cons

Please tell me why

Simply because they need to stand the test of time. Another issue for me is they are owned by Fouani Nigeria, don't trust those guys with standards.

Firman is not pure copper. I confirm it. Check the pix

How did you confirm it, if it's pure copper or not? From the pics I didn't see how it's confirmed. The first pics isn't Sumec firman. Are you permitted to inspect the coil to confirm if it's copper or aluminum?

I don't have their review and I can't say anything about their generator. What you need to consider in buying generator is availability of OEM parts.

Go to any of their accredited showrooms outlets. Don't buy from any online stores. I respect don't buy from online stores

They opened it. The coil is not pure copper and its few. Compared to elepaq. Elepaq own is pure coper and not mixed with aluminium. I checked both out. Firman try but they are doing substandard now

Is the store an accredited Firman store? It's a well known fact that Firman being the most popular brand has more counterfeit out there.

I think I will go with elepaq

At all but I checked everything,all was intact including all the trademarks crested logo but he discouraged me from buying that particular brand. When buying gen,tell them to open the coil to confirm its its pure copper or more aluminum mixed with less copper

Sure you should in this case but I don't think that Firman is original.
