The amp rating gives an idea of the wattage, i must say the plasma is a power guzzler, maybe should be thinking of replacing it. I'll suggest you go for a 2.5kva inverter using 4pcs 12v 200ah batteries. If well managed you could get more than the 8hrs. you stated.

Local pure sinewave will cost you 550k with installation if you are in Lagos.
Foreign sine wave will cost you 620k with installation if you are in Lagos.

Many thanks

Thanks for the feedback. Pls do I need a charger for the local package?

Thanks

Good evening boss

Need ur WhatsApp contact

Will love to av the UPS

Hipe it's in working condition with good battery

Seamareggae:
I need an inverter with 2 batteries that can power a tv, 2 fans, 4 bulbs nd then charging of phones nd other items, at least when the 2 batteries are full, will it be enough for atleast 18hrs, nd how many hrs, will the batteries take to get fully charged nd then finally the cost.


Pls answer me naaa....

Hello Feflo,

Pls what is the difference between Deep cycle battery and Valve Regulated Lead Acid (VRLA) battery. Can you you recommend VRLA battery for your inverter?
Thanks

feflo:
Sealed Lead Acid Batteries

Sealed lead acid batteries are also known as valve regulated lead acid (VRLA) batteries, recombinant batteries and often called maintenance-free lead-acid batteries. Examples of VRLA batteries are:
• Absorbed glass mat (or AGM)
• Gel cells

The term “seal lead acid battery” is misleading: a sealed battery would be a safety hazard due to overpressure risks the battery is overcharged. There is always a safety valve present, hence the name valve-regulated. Even the term “valve regulated” does not really describe this technology. These are really “recombinant” batteries. This means that oxygen evolved at the positive will mostly recombine with the hydrogen ready to evolve on the negative and thus prevent water loss. The valve is only a safety feature in case dangerous amounts of hydrogen are produced.

Flooded Lead Acid Batteries

[quote author=feflo post=48018992]AGM Batteries
Absorbent glass mat (AGM) is a class of lead-acid deep cycle battery in which the electrolyte is absorbed into a fiberglass mat. The plates in an AGM battery may be flat like wet cell lead-acid battery, or they may be wound in a tight spiral. The internal resistance of AGM batteries is lower than traditional cells, they can handle higher temperatures, and self discharge more slowly.

These batteries have a valve which will activate when the battery is recharged at high voltage. Valve activation allows some of the active material to escape thus decreasing the overall capacity of the battery. The lids /vents typically have gas diffusers built into them that allow safe dispersal of any excess hydrogen that may be produced during charging. They are maintenance free; and they can often be oriented in any manner, unlike normal lead-acid batteries which must be kept upright to avoid acid spills and to ensure the plates are sitting in the electrolyte.

AGM batteries are totally sealed and are easy and safe to transport
They never need topping up with water
They can be safely mounted inside a boat, car, caravan, motorhome etc
AGM batteries only need to be vented to atmosphere, they do not need to be in a sealed box vented to the outside like wet batteries, and
can be mounted on their sides or ends if needed.
Due to their very low internal resistance AGM batteries will fully charge at a lower voltage, and accept a much larger charge current, so when
charging from a standard car/truck alternator these batteries will all but fully charge, and they will charge quickly, in about 3 hours!
AGM batteries can be discharged deeper than conventional deep cycle batteries without major damage.
AGM batteries only self discharge at the rate of up to 3% per month, and even after 12 months sitting idle can be recharged and put back
into full service without any major damage. (A standard deep cycle battery if treated the same way will have destroyed itself, it will no longer
hold a good charge)
AGM batteries were originally developed for the military, they are very robust.

Feflo, how much does this flooded battery cost?

feflo:


A 1.5kva 24vdc system will do but I doubt if it will power those loads simultaneously for 18hrs. If you are able to manage it well you could get 12hrs upwards. The batteries should be fully charged BTW 6hrs and 8hrs

A converted UPS with 2 fairly new 12v 200ah batteries will cost 145k without installation.

A regular 1.5kvà with 2 new batteries will cost 280k without installation.

Thanks.

@Feflo,

Femi, do you have the MHB battery in stock?

Thanks

turok:
@Feflo.... Please oh. Is mercury elite 1200 pro UPS 24v? It hàs two battery

feflo:


Yes sir, its 24vdc, i've converted quite a few of them, make sure you don't overload it.

turok:
Thanks.
Since you have converted it before, can you direct me on which wire to connect the fan? Please. Also I believe I will be using 24vdc fan.

Hello, I need an estimate for inverter that can power the following :
1. 12 energy saving bulbs
2. 6 wall fans
3. 3 ceiling fans
4. 1 standing fan
5. 1 TV set
Length of use : 8 hours daily. Thank you.
Base estimate on converted UPS please

feflo:


The conversion is replete on the pages of this thread. Take time to go through it and you're good. Many Thanks

turok:
@Feflo... Thanks I will do that. Which number are you using on WhatsApp?

There is an invention I want to discuss with you.

Please house I urgently need your help. I need to buy a 24v pure sine wave inverter at most 1.5kva but preferably 24v, 1kva capacity but this is scarce. I am currently considering a BTS inverter which I saw on Konga and Jumia, please is that a good inverter? Which other one can you recommend. Thanks.
