geesampower: hope you see this post. I have 10 desktop computers with flat screen monitor and a projector with an energy saving bulb. I need to know what capacity of, number of batteries and the inverter will be required to power them for like 6-12hrs and other required things for the above. Furthermore, i want to know does the fluctuation of light (caused by iron wielders nearby) affect the charging and life of the batteries during the day but at night the light is good and stable for charging. attached is the image of the power pack specification which is for all the 10 system.

uvalued:From the image that device uses 720 watts multiply x 10 hours 7200 Watt hours. You have ten of them 72000 Watt hours. I need to see the information on your flat screen and projector. Just for the desktops alone you need 3000 ah in batteries . For a 50 state of discharge You need new computers. They should consume 1/3 what yours consumes. You could elect not to have all of them on at the same time for ten hours. , *******Correction*****. I read the bottom and the maximum output power is 275 x 10 =2750. Times ten computers 27500. 1400 ah in batteries at 50 %. |

zeestone99:Look at the picture. It is right there amps x volts. I simply multiplied what he supplied. I want to agree with you. We have always used 250 Watts including the monitor for our calculations. However the picture that was presented says something different. Thank you for your observation. The sticker put the maximum power output at 275 watts |

geesampower: Why do you calculate the load of appliances in watts? example: You said a 1hp airconditioner is about 1,200w, why do you calculate it that way? |
Re: Beware!!! 5 Reasons You May Regret Spending On Solar Power!!! by geesampower(m): 6:58pm On Aug 14, 2015 |
jpphilips:The load or power rating of any electrical device is the product of the voltage and current the device/appliance/machine/electronic uses. You can't independently use the voltage or current requirement of such to determine what it takes to run it. That is why watts is used by electrical engineers to rate the power requirement in electrical devices. |
Re: Beware!!! 5 Reasons You May Regret Spending On Solar Power!!! by jpphilips(m): 7:48pm On Aug 14, 2015 |
geesampower: Do you agree that some 1hp airconditioners are rated 950watts?? And some refridgerators are rated 1000w? do you agree with any of the above? |
Re: Beware!!! 5 Reasons You May Regret Spending On Solar Power!!! by chris81964(m): 8:36pm On Aug 14, 2015 |
jpphilips: The norm when translating HP to watts is 745 or there about. However your 1 hp AC can surge up to 3 times that number on start up. And if it is not properly maintained or repaired can use more than that rating. While we can all hypothesize it is easier to look on the back or side of the unit and you can calculate what the number is. Manufacturers are making equipment with much more efficient motors. 1000 W refrigerator or Freezer. It has to be a commercial unit. I have seen home refrigerators repaired by Baba Seun (you know him) that pulled over 1000 W. Can't run those on Solar or an Inverter. Waste of energy |
Re: Beware!!! 5 Reasons You May Regret Spending On Solar Power!!! by geesampower(m): 9:43pm On Aug 14, 2015 |
jpphilips:That is very possible. It's possible in future for 1hp airconditions consume as low as 100watts, no controversy about variation in the wattage. There are 1hp pumps that consume 750w and some consuming as high as 1000watts. The technology is what makes the difference. Example. A brushed DC motor (BDC) and a Brushless DC motor (BLDC) can both be rated 1hp in what ever application were they function, and though they are both 1hp, the BLDC motor will consume at least 20% less energy than the BDC motor. So saying a 1hp Ac can also consume as low as 950watts is not out of place, it only shows there is a more efficient technology in use in that particular Ac. So that does not in anyway say we shldnt use Watts to calculate energy need. Or what is your point sir? Hope I am not missing anything? Is the watts quoted the controversy or the use of watts in calculation? Visit the website of LG, samsung and you will discover most of their 1hp Air-conditioners are rated 1200w |

geesampower: Since you agree, my next question goes thus; modified When you connect a 950w Airconditioner to a 1000w voltage regulator (stabilizer) what happens? when you connect the 1000w fridge to a 1000w voltage regulator, what happens? |

Re: Beware!!! 5 Reasons You May Regret Spending On Solar Power!!! by geesampower(m): 10:12am On Aug 15, 2015 |
jpphilips:Though your question is off topic. I will oblige you. I will like to see a true 750w air-conditioner (1hp) Back to your question. Connecting a 750w air conditioner won't work. The start up of a 750w air-conditioner will most likely be 2000w or more. A 1kw regulator will never work, I Mean NEVER work with a 1kw rated refrigerator. You either blow out the fuse, transformer or the overload circuit breaker kicks in to stop the load from damaging the stabilizer. |
Re: Beware!!! 5 Reasons You May Regret Spending On Solar Power!!! by jpphilips(m): 1:41pm On Aug 15, 2015 |
geesampower: please it is not 750watts but 950w. I guess you have not tried it before that is why you could not see the reason why calculating load in watts is wrong. Let me answer it for you, a 950w Airconditioner connected to a 1000watts stabilizer will fry it instantly even though the rated wattage seems to be "ok", the starting current can be annuled by running the AC first through a switch mechanism that will regulate in micro seconds transferring the load to the 1000w stabilizer after a while, it will still fry it so the starting current theory holds no water in this case. conversely, A 1000w refridgerator will run perfectly on a 1000w stabilizer the reason is simple, A 1000w stabilizer is rated 2.6A while A 1000w refridgerator is rated 1A, you can see clearly that even if the fridge decides to double its starting current, the 1000w stabilizer still have a current clearance of 0.6A. That way no shaking!!. Let us go and apply the same theory on the 950w Airconditioner. The 950w Airconditioner has a strating current of 5.2A and a running current of 4.6A against the 1000w stabilizer of 2.6A. you can see clearly that starting current or not, there is no way the stabilizer will stand a chance. Nigerian technicians make that mistake a lot that is why there are a lot of homes that are powered with oversized generators and inverters. It is still unclear whether the technicians do it to make the client pay more to their credit or the technicians are simply ignorant. When someone says he has a 1hp Ac, dont calculate his load as 1,200w like you erroneously did rather his load is 4.6A -5.2A depending on the make and model. This is not a subject of arguement because all the gadgets we mentioned are owned by people here, it wont be long before they tell you how wrong you are. The actual load in an electrical device is the current rated in Amps and not the Power rated in watts or horsepower. Learn that and move on!! NB: IT IS A CONFLICT OF INTEREST TO ASK THE SELLER OF A GENERATOR OR INVERTER TO CALCULATE YOUR LOAD, CLIENTS BEWARE!!! 2 Likes |
Re: Beware!!! 5 Reasons You May Regret Spending On Solar Power!!! by geesampower(m): 2:25pm On Aug 15, 2015 |
jpphilips:Lol Won't indulge u. Thanks While negating the operational voltage, you went ahead to work on current alone. We could go on with this but I won't. You have not made any point that abolishes the use of watts (power) in load And I am sure when balancing how much load a battery will power for a certain period, your logic would say we shld leave out voltage and focus on just the amps. Right? This is hilarious. And when considering what a solar panel can power I shld ignore the voltage too right? So a 100w panel that delivers a current of 5.5A is enough to power a deep freezer. Right at least according to your argument, we shld forget about watts (power) and focus on current (amps). So 100w panel is all I need to invert to alternating current at 5.5amp that it generates and I would power 5 freezers using 1amp. Hope you know this is online. Many will see this around the world. Those who have a foundation in physics or electrical engineering would be perplexed reading this 2 Likes |

Some times I wish everyone has a good foundation in physics. You would just laugh at some "experts" online. |
Re: Beware!!! 5 Reasons You May Regret Spending On Solar Power!!! by jpphilips(m): 5:07pm On Aug 15, 2015 |
geesampower: Mention one appliance in our homes that is rated 100w/5.5A? I gave my examples with appliances all of us can verify and you pull out fiction from the bubble of white garment expertise. Anyways, I don't really blame you I blame ignorant people who allow a seller to calculate their load. My arguement is based on the mannerism you calculate people's home appliance load which is wrong. You said A 1000w fridge can not be powered by a 1000w stabilizer, the proof I gave is beyond reasonable doubt, it is up to your would be clients to put your ingenuity to a test, pray you dont fail. 2 Likes |

jpphilips:Oga explaining common physics to u is a waste of time. U are just here to prove u 'sabi'. Of which what u are saying is totally flawed, how can anyone say it is wrong to calculate load with Watts. This is incredible. Keep waiting for my clients to come and complain u will wait for ever. |
Re: Beware!!! 5 Reasons You May Regret Spending On Solar Power!!! by geesampower(m): 5:33pm On Aug 15, 2015 |
