chux76: I need the best quotes for an inverter set up that would power the following,What size/rating of Inverters and battery can power the below conveniently:

1) 5 UNIT LIGHTING BULB POINTS
2) 3 CEILING FANS
3) 3 LG 14" PLASMA TV's
4) ONE LAPTOP

Pls get back to me asap.

mrtnt: Do u still hv those fairly used batteries?

feflo: Thats exactly what the Auto switch does, you'll hardly know when NEPA comes in or goes off. What i mean by effective management of your load is this, its expected that you'll have a NEPA indicator to tell you when utility is absent or present, also the inverter display tells you either you're on battery or utility, as soon as you discover that NEPA supply goes off, you'll have to go round to reduce the load on it. Remember the inverter can power all the load but our goal here is to increase the runtime of the battery and this can only be achieved by switching OFF devices thats not absolutely necessary at every point in time when you're on inverter alone.

Hope this answers your question and thanks a million for your interest.

feflo: 2. If I hv 1500w inverter wt 200ah deep cycle battery, hw long (average no. of hrs) wil it last for:
1 unit x 21" TV
1 unit x decoder
1 unit x laptop
2 units x ceiling fan
8 units x bulb of 60w each


A 1500W Inverter using a single 12V 200ah deep cycle battery

Total battery watthr is 12V x 200ah equals 2400W
Your inverter is not designed to drain the battery completely, assuming you only have 1800W usable battery watthours.
Your total load stated above is about 800W. This means that your Inverter should work for 3hours. Take note, when using inverter, its not expected that all the above mentioned load will all be ON at thesame time so if well managed you can have like 6hours or more out of the battery. Thanks

I will respond to the other questions later, once again, thanks.

feflo: 1. What diff. is there btw 1500w & 2000w inverter? What can 2000w do dat 1500w will nt be able 2 do? Enlighten d house.


Literally, your question is like asking the difference between N1500 and N2000. Everyone knows that N2000 will purchase more goods than N1500 but technically, a 2000W inverter has a greater load carrying capacity than a 1500W inverter. Assuming in my house, i have an Electric Iron rated 1000W, a fridge rated 200W and Ceiling fan rated 50W. My total load becomes 1250W. A fridge will require 2.5times the rated watt to start, this means a fridge will need 500W to start.
If your inverter is 1500W, its not possible for you to be using your Iron and still put on the fridge, the inverter will shut down on overload but the 2000W inverter will pick all your load at the same time. Hope this answers your question and thanks for your interest.

mrtnt: Do u also sell external battery charger? And hw much?

Lookng at 1200w or 2000w inverter wt 200ah battery, is external charger needed? And which would u recommend?

mrtnt: It's ok.


Dis issue of 'deep cycle' battery, pls, is dis diff. frm typical trailer vehicle battery? If yes, pls what makes d diff.?

mrtnt: Now looking at a typical situation where all d above listed loads are ON with Nepa light & suddenly Nepa takes light. Wt dis inverter that has inbuilt auto switch, I want 2 believe dat none of d loads wil go OFF cos d power wil switch immediately to battery source. Is dat nt what d auto switch does?

Or u mean, if Nepa takes light, all d loads go OFF? Then, I hv 2 go around d inverter & manually switch over to battery power? And then start to ON d TV, decoder, laptop, fan, etc all over again?

Pls clarify.

mrtnt: Thnks 4 your insightful analysis. Hope dis also helps some1 out there too!

However, u omitted question 3.

What good battery frm your stock wil u recommend wt your 1200w? Brand new or like-new? What is d implication of each vis a vis durablity. Hw much do u sell each?

feflo: Solar Cable
High quality wire is a key factor for your system. choosing the lowest cost wire usually result in systems that are inefficient. For solar current, high grade solar wire is the best option. We sell pure copper solar wire, encased in a rubber sheathing.The rubber sheathing on solar wire protects against electrical shock in damp conditions and prevents damage from outdoor elements and the sun.

Batteries

How much power does a battery hold? True deep cycle batteries contain Watts, AMPS and Volts. Viewing the label on a battery, we can see how
many volts and amps a battery contains. By multiplying the VOLTS times
the AMPS we can estimate how many WATTS of power that battery holds.



VOLTS x AMPS = WATTS PER BATTERY

6 Volt Battery x 250 AMPS = 1,500 Watts

12 Volt Battery x 100 AMPS = 1,200 Watts



Using Solar to Charge a Battery

The big question – How long will it take to charge a battery? If a battery
holds about 1,200 watts of power. It would probably take a 100 watt
solar panel about twelve hours to charge that battery from empty to full.
In comparison it would probably take a 50 watt solar panel about twenty
four hours to charge that same battery from empty to full.

ceejay80s: Ì need 30AH or 50AH deep cycle battery

cccimisioluwa: what is the cost of 200ah
and what make do you have and you guarantee period. thanks

arbitrage: Thanks for feedback but here above is the question I asked before
