Buying the Best Inverter
It is best that you gain some knowledge about what to look for in an inverter before buying one. Read on to know some considerations to make before buying an inverter and tips to buy UPS for home:-
#1)Consider your power consumption
Before setting out to buy an inverter for your home, it is always best to know beforehand the rough estimate of your total power consumption. Take any average summer day and make a note of what all you need to power. An inverter is very different from a generator in the sense that it cannot run all the electrical appliances of your house when the electricity goes out; you have to select the few indispensable appliances you want to stay running all through the day, no matter what!

Determining the combined load that would be run using the inverter is of critical importance in purchasing the inverter of adequate size. The watts of power drawn by every single appliance you will connect to your inverter can help decide the VA rating of your inverter. An inverter can back heavy electricity drawing appliances such as refrigerators as well but powering such devices has its own downside—the inverter battery is going to last for fewer hours than it would if devices such as heavy refrigerators were not powered using it.

#2)Understand how an inverter is different from a home UPS
A home UPS is the same as an inverter, as far as the functionality aspect is concerned—both the devices are used to convert direct current to alternating current which is in turn used as a backup option to generate power. However, the main point of differentiation between an inverter and a UPS—the acronym for Uninterrupted Power Supply—is that there is no time lag between the devices being powered off in the event of a power cut and being powered back on subsequently in case of a home UPS.

However, with devices powered by an inverter, there is a very short period of total blackout when the electricity goes out. It is only for this reason that most computers and laptops in homes and offices are connected by UPSs instead of inverters so as to allow users to save their critical data before powering their machines off.

#3)Know which appliances you can power using an inverter
An inverter can be used to run appliances such as fridges and air conditioners. However, the motors of the aforementioned appliances are equipped with compressors that require huge amounts of currents, especially in order to start up. Thus to cater to such heavy-current-drawing appliances, it is best that you buy inverters that have high VA values and sizes or inverters specially designed to cater to refrigerators and air conditioners.

#4)Know the VA rating that your inverter requires
VA ratings and watt ratings are not to be taken interchangeably. Appliances that we use around our homes such as lights, bulbs, refrigerators, air conditioners et al are the ones that consume power and hence are rated in Watts. In contrast, power generating equipment such as inverters, uninterrupted power supplies, generators et al are rated in VA.

VA is actually apparent power and is the product of the voltage and the current supplied by the equipment. The ideal case scenario calls for both, the VA value and the watt value to be the same. However, in actual circuits, it is not practically possible for them to be the same. Do not be misled by manufacturers into believing that both of them are the same.

#5)Miscellaneous Considerations
As with any product, with a UPS and inverter too, you must make sure that the products are guarded under a stipulated warranty period by the manufacturer. Inverters are appliances that require close to no maintenance at all, until and unless they stop functioning altogether. An inverter is not 100% efficient because it uses a part of its energy to power its own circuitry and run a cooling fan.

Now that you know all that there is to buy the perfect inverter, make sure you buy only from reputed manufacturer. Mercury Inverters

Hi Guyz, please I would like to make enqueries as per usage of my inverter. Currently, I have a 2Kv inverter, which is getting the job done, but I have a standing Fan (ORL), which I was advised not use with the inverter mainly because the fan has big coil. The fan watt is 126w. Is this reason justified not to use it with my inverter

Your 2kva inverter will power it but will eventually drain the battery fast.
The more the load the lesser the back up time

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.

AderibigbeAAA:
The voltage is between 190-200

The voltage is low, it could affect the the battery life span and backup time due to the low voltage.
I advise you get a stabilizer so as to stabilize the voltage for optimal charging and efficiency .

Hello sir, what is the Nepa voltage in your area? To determine where the problem is coming from.

AderibigbeAAA:
My inverter doesn't last long as usual.

My Inverter vendor said I will need a stabilizer as the power from PHCH didn't charge the battery well. Whereas, the inverter indicated battery full before power outage.

Please how true is this?

Avoid local battery manufacturers
Many are tempted to buy very good brand inverter but local brand battery which is can be a very incorrect decision based on many aspects. Local brands usually do not follow safety, efficiency standards and they tend to have a relatively low lifespan. But local brands vouch for it and say as they are manufactured very close to this place they are offering very cheap, almost half of the price. But selecting the right battery is more important than inverter based on safety concerns. Many battery types release little fumes and poisonous gases like carbon monoxide and big brands ensure the emission to be the lowest level, which local brands do not give much importance. Local batteries tend to insist excessive maintenance work. Apart from that, local batteries do not have warranty or guarantee. Not only that do not buy refurbished batteries even for a cheaper price as they will be most likely unsafe and have shorter life span.

Hello sir, you can open the indicator nob to check the level of the water.
The maintenance do have effect on the backup time.
It is better to get the water from Mercury
Contact Mercury Direct in 07037451701 for more information .
Thanks.

Hello house.

I started using my two 200ah Mercury tubular batteries with 2.4kv 24V Mercury inverter on the 27th July 2020, when is the best time to refill/top up the battery water? Meanwhile, i have been checking the battery water indicators which haven't dropped at all (i didn't open the indicator nob or do i need to open the battery water nob to check the level from top?)

Moreso, I discovered that the back up time/hours has reduced but not drastically. I noticed drop in the back up time. Does the water maintenance has the effect on this?

If I'm to top-up the water, is there a particular water to use? Must it be from the Mercury company or just any acid water or distilled water? I'm scared if using any battery might spoil the whole battery.


Thanks
