How can I choose the right inverter battery for my home?
The first thing you have to do is to calculate what you ‘needs’ are. That means everything you will be powering from your inverter. Everthing! Coffee makers, lights, TVs, PCs, fridges, freezers and etc. and etc. Some things like coffee makers and toasters draw high currents for short periods and others like lights and TVs low currents for long periods. It will also vary my season and weather. Once you have worked that out you know what you require in KWH from the battery system. Add at least 20%.Batteries are usually rated by VDC and AH capacity. That means you need a battery that matches the output of your charging system and the input of your inverter. Generally the higher the voltage the more efficient the system.At this point you go looking for a battery. It absolutely has to match the charging system and inverter input voltages.Used nickle/metal hydride batteries from electric cars may be possible. Lithium type batteries may be possible. I doubt very much if they would be cost effective due to their voltages, charging profiles and cost.What’s left? I’ll be damned. Flooded lead acid (FLA) batteries! What? The FLA battery has been around for over 150 years! Isn’t a new technolgy better? Maybe.But no newer technology can give you a more cost effective solution.FLA batteries are a commodity product. They are manufactured and used by the millions. You can buy new and used FLA batteries that will last for years with decent installation and maintenance. They are green too. Over 95% of the lead in an industrial battery is recycled. So is the acid and plastic.If you are going to use FLA batteries you want ‘A’ battery of the desired voltage not a bunch of batteries in parallel. Big 2 volt cells in a string like the telephone companies use or a forklift battery of the right voltage. That way if a cell goes bad you can have it replaced.If you do your homework per paragraph one you have choices. Stick with flat plate batteries. Tubulars have more power but also cost more and have a different charge profiles.This answer is based on my experience assisting farmers, ranchers, cottage owners and others off grid.
How can I convert the single phase to three phase?
There are 3 ways (or more )Couple a single phase motor with 3-ph generators (this method is not much practical )You can go for Ernoconverter .Let me explain ……. Suppose you are having a 3ph induction motor . Connect it in delta configuration . Apply 1ph supply to any of it's winding amd gove an.external starting torque . Now you can.see there is a vtage across each winding . So , thus youay have 3ph power from single phase supply . But this system is too much unstable ,that's why it is notuch reliable .3. Now here is the sophisticated way out . Just connect a single phase rectifier with a 3-ph imverter . This method is too much reliable as you can control the output voltahe and frequency very easily even you can add remote control ( if interested ) . Here is the circuit diagram ……My phone camera is not too good as well as my handwriting . Hope you understand the picture and I haven't shown firing circuit for simplicity . You can control the firing pulses using microcontroller or arduino .For any query , mail id : hasmatmondal141@gmail.com
What is the HSN code for ups, inverters, and batteries?
UPS/Solar Inverter: 85044090Static converters: Electric inverter: 85044010BATTERY TYPE: HS CODESLead-acid, of a kind used for starting Piston engines: 85071000Other lead-acid accumulators: 85072000Nickel-cadmium: 85073000Nickel-iron: 85074000Nickel-metal hydride: 85075000Lithium-ion: 85076000Other accumulators: 85078000
Is it possible to connect a UPS unit on an inverter?
Such a queer combination is only used when supply quality is very poor, with very wide voltage variations on lower voltage side. In such case, first inverter raises the voltage to a limit, which can in turn be handled by the second one to give stabilised output.Basically otherwise UPS as well as inverter are same - both have batteries and are used to provide stabilized output despite variations in mains supply.
How many solar panels and batteries are needed for a 3kW solar system?
There's allot more to sizing a system.3kW solar is easy to achieve, but how many hours backup do you need?16 x 100Ah lead acid batteries will give you roughly 3kW for 2 hours, assuming a DOD of 50%.If your evening loads are kept to a minimum then you should get quite a few extra hours out of them.16 batteries is also easy to wire up for 48V, which most inverters ask for.The biggest thing to check is the rating of the charge controller. If you plan on depleting your battery bank every day, then you need a solar system with inverter that can satisfy the AC load during the day and ALSO provide the energy to charge the batteries via the charge controller.That is why the clients wishes/ intended usage patterns are critical design considerations.Often you will find a backup heavy system has a very large PV end to it, unless you are happy using grid power to charge the batteries in off-peak times…many factors to consider indeed!
Can you use just a car battery to power a TV and a lamp?
Folks with campers/RVs do this all the time, but often with a second "house" battery that is isolated from the start battery so that if you do deplete it you will still be able to start the motor when you are ready to leave.So yes, you can... but for how long? A car battery can power an LED television and LED lights, especially if they are 12V, quit easily. An old-fashioned TV and incandescent light bulb it can power (through an inverter) much more briefly...It all comes down to the storage capacity of the battery, the state of charge, and your ability to charge it back up again.If, for example you have a 100 Amp Hour lead acid battery that means you have 50 useable Amp hours. If you are watching TV and running your lamp for 5 hours, then you can deliver 10 Amps per hour - or 120 Watts. A decent sized flat screen TV will draw on the order of 100 Watts. A decent LED lamp could be 8-12 Watts.
How can I write a request letter to my administration for the installation of a new electric fan in our office?
I would suggest a short, to-the-point request that could even be set up as a memo with the organization “To:”, “From:” and “Re.”To: General Electric AdministrationFrom: 5th Floor Typing PoolRe: Need for Air Conditioning on our floor.It is extremely hot on the 5th floor and all workers affected would be extremely grateful if those in a supervisory position would use the accompanying work order to obtain the necessary cooling equipment, in order to raise the productivity of the workers affected and provide a better work environment.Thank you for your attention to this matter.Sincerely,At this point, have everyone on your floor sign the letter, make copies, and forward it to anyone who is at the top of your company and, therefore, in a position to allocate the funds for whatever is needed. (*Note: my use of General Electric was just an example, as were the other details.)Use a computer and make copies of whatever you send.
Can you run a PC off a car battery?
If there are any science wiz's out there. Would the following work: Use something (e.g. a exercise bike/treadmill) to charge a car battery and use the car battery to power the PC. Would that work? If it would work, for how long? Just a random thought....no biggy...you thoughts please.
