Gurus in the house, please does anyone one know if a PRAG GED GELL BATTERY 12v 200 ah is as good as other inverter batteries eg Zenith battery in the market? Kindly advise

Thank you sir yr take on this and other issues is so enlightening.

[quote author=George_D]dsunmade,

yes, they are truly intelligent. and yes again, you're right about the sulpahation part.

charging your batteries to just 85% full is not good enough but unfortunately most peeps don't know this.

the above reason is why most inverter batteries fail. you see peeps keep changing out batteries every two years or less
and they even see this as normal. i was at some other inverter thread a few days ago and was shocked to see a self-styled 'inverter expert' spreading this kind of mis-information.

most average inverters we see around these parts, including cyberpower, sukam, nexus, mopower, prostar, etc are the culprits. they never charge your batteries even to absorption not to talk of float. but then, they are what most peeps
can afford as going for those high end types in the list above costs quite a bunch.

so, if you can afford it please go for high end as far as inverters are concerned. but if you already have solar then your charge controller will always take off from where your inverter stops - provided again your charge controller is a high end type.[/quote]Goodmorning, please kindly clarify. If one gets any of d high end inverters listed above will there be need forfor one to still use a mppt solar charge controller?

Chiefo goodday can see business is booming on numerous threads I need an extra key and d spare tyre cover 4 d liberty. Kindly advise

Guru's in d house I have an offer for a tristar mppt solar charge controller 60 amps for 125,000.00 and d meter display for 20,000.00. Are dy r good bargain or could I still get it cheaper? Kindly advise

[quote author=inspired_m]If Other Major Importers Set a Price Above than Ours, We may have to Upwardly Review Our price.

Anyone that Orders from Us Now Will be counted LUCKY.

[quote author=George_D]hello dunka,

the prag servo does not carry the whole house load. if it did i would not have been able to switch it off like the
way i'm doing right now.

as you rightly guessed, the water heaters and cookers are all connected to public power. that being said, every
other house load is being powered from the inverter, namely the deep freezer, fridge, water pump, tvs, fans, home
theater, lighting, etc.[/quote]Thank you sir

[quote author=George_D]prag servo, still on holiday! [/quote]Please wanted to find out if your Prag servo stabilizer is connected to carry the whole load of yr house or did you remove some heavy loads such as waterheater, cooker etc

[quote author=George_D]dunca,

i think that's about the best bargain you can get for suntech 280w right now.

some peeps even sell for 120k and above. except maybe you want to go for joy solar?[/quote]Thank you sir must say it was due 2 yr influence as I told him Warri man referred me. as

[quote author=onome25]U DO NOT NEED ANY OTHER CONNECTION APART FROM UR DSTV CABLE THATS ALL(so simple) &U ARE GOOD FOR UR EXCITEMENT IN SPORTS & MOVIES.[/quote) Good day but I am not using Dstv only strong decoder. Kindly advise.

BUTONEDAY: @ DUNKA,

What is the cost of the 280W Suntech Panels?

I got a quote of 70, 000.00 per panel from Mr. VITUS when i called him on d phone. gurus kindly advise if dt is a good price or can I get a better deal.

If one gets one of d HD boxes listed above how does one install when sent?

Goodday can u get a solar charge controller?

Mono-, Poly-, Thin Film: What’s the Difference?

When researching solar photovoltaic panels you will probably see references to the materials that make up the wafers. Panels will not only be classified by their rated power output, but also by the wafer or cell material. Silicon is the main element in almost every panel on the market. However, the formation of the silicon determines its characteristics. Most wafers are made from either Monocrystalline or Polycrystalline silicon. Both are made from the element, but their molecular structures are slightly different. Amorphous silicon, commonly known as Thin Film, is a different beast all together and is also common, especially in commercial applications. Hopefully the following lists can help shed some light on the differences, pros and cons of these three materials and help you decide which one should you choose for your application

The newest of the technologies mentioned
Created using a process that makes sheets that can be rolled out like carpeting
Less efficient in the standard testing conditions than mono- or poly- crystalline
The cheapest of all the mentioned technologies, but because of the lower efficiency only cost effective if used for very large projects.
The most heat tolerant of all the mentioned materials. In fact, some studies show that efficiencies for thin film rise in high temperatures.
As this is a newer product, most installations are no more than 10 years old making its longevity and durability unknown.

Monocrystalline:

Oldest of the 3 technologies. The first solar cells ever made were monocrystalline
Molecular structure is formed from a single crystal (patterns throughout the structure will be identical)
Formed in a cylindrical mold and cut like slices off a loaf of bread. These cuts are squared off so wafers are usually squares with rounded corners.
Most expensive of the 3 materials.
The uniformity in the crystalline structure makes this the most efficient of the 3 materials under testing conditions.
Extremely durable technology. Many of the first cells ever made (in the late 1950s and 1960s) are still working today.
The least heat tolerant of the 3 materials. This means that panels made using monocrystalline wafers are subject to greater loss of power output in temperatures above 70 degrees.

Polycrystalline:

Most common for residential application.
Molecular structure built from more than one crystalline material.
Formed in square molds and cut like slices off a loaf of bread
Less expensive than monocrystalline cells but more expensive than thin film
Currently the most cost effective material for residential application
Slightly less efficient that monocrystalline cells, but new technologies are closing this gap.
Extremely durable technology. Many of the modules are still operating after 30 years
More heat tolerant than their monocrystalline counterparts but still have a slight drop in power output in extreme temperatures

Thin film (Amorphous Silicon):

The newest of the technologies mentioned
Created using a process that makes sheets that can be rolled out like carpeting
Less efficient in the standard testing conditions than mono- or poly- crystalline
The cheapest of all the mentioned technologies, but because of the lower efficiency only cost effective if used for very large projects.
The most heat tolerant of all the mentioned materials. In fact, some studies show that efficiencies for thin film rise in high temperatures.
As this is a newer product, most installations are no more than 10 years old making its longevity and durability unknown.

Thank you for d informative write up

TotalGreen: hi,
this is strictly my view.
u setup is cool, u just need to add one more panel, i am assuming the 3.5kva is a 48volt system.
for 48volt the "Tristar mppt controller 60amps", u need to connect the panels in multiple of 3's, so u need 6panels, but a total of 12(3x4)panels should fill up your "Tristar mppt controller 60amps" finally before you buy a new one.

i dont share the same view on "thin film panels of 90w has a better efficiency dn poly or mono panels".. but thats just my take.. i would advice you browse the internet and you get your answers on this, not just one installer telling you what someone else probably had told him without backing... hope i dont sound hash.

just that with solar i always advice you start on the correct technical foundation..

Thanks a million. You gurus really the best.

Goodday all being silently following this thread and I must say I am really impressed with the information gleaned. Being a learner please gurus in d house wanted yr thots/advice on ds hybrid installation:
1. 3.5 kva su kam inverter
2.4 12v 260ah Zenith batteries
3. 5 280w Suntech panels
4. Tristar mppt controller 60amps
How best would I get d maximum output from d panels or wld I need 2 increase dm? Also installer is saying dt thin film panels of 90w has a better efficiency dn poly or mono panels and is suggesting dt we go for ten 90w thin film panels? Your advice would be highly appreciated.

onome25: 4940 can not accept dongle because it does nt have rss32 port.it doesn.t accept cc cam account.it is married to my tv cards.
i do not regard strong hd reciever as FULL HD MACHINES because the features looks too ordinary.
GET A BETTER & QUALITY HD MACHINES THAT DO NT NEED UPGRADING, RS32 COMPATIBLE( DONGLE SUPPORTS & ACCOUNT ACCEPTANCE)
SUPPORTS ALL DSTV CARDS.
SO THE LIST ARE HERE tnx.

Goodmorning please how about SRT 4663XII? Secondly if you were to choose an HD receiver 4 yr personal use as u listed above which would u go for?

onome25: ALL OF THEM ARE WIRELESS & SKYFOX HDMI HAS SIMSLOT

please which of your dongle works with Strong 4940 decoder?

Goodday having problems loading the pictures but as earlier confirmed vehicle is live here at Jos and it is exactly as d pictures Chief Inspired had communicated. Honestly, I had never met face to face with inpired before deciding to go ahead with this concluded transaction in fact my people thot dt I must be crazy for sending money to a lagos based car dealer without knowing or dealing with him b4 as people here are not used to buying cars thru preorder rather dy buy ones as seen at d various car stands around town.

So to their great surprise and amazement when dy saw d car in my possession dy were really impressed dt all worked out well.

I for my part with following inspired on Nairaland even despite a slight delay I had no doubt dt he is genuine and here 2 stay .I have no doubt dt d sky is d limit for inspired.

Everybody has his own ways 2 get a car to own but I believe dt 2 get a a clean non accidented car pre order is d way 2 go and Inspired should be considered a 1st choice . With a preorder u get d exact color and specifications u want and u are sure dt yr car is what u get.

I have no doubt dt if I am still 2 get another car pre-order would still be d way for me.

Chiefo do keep up d good work for providing us with d cars of our choice and not salvaged vehicles dt you would not recommend to yr family members! Talk 2 u soon. Regards

Delivered,Delivered Delivered. Car was delivered to me safe and sound yesterday evening. Details to follow

I dont do Blackberry stuffs. Call u later for further discussion. Regards

Inspired goodday and welldone. Kindly advise me when the driver leaves Lagos and also his details. Regards.
