MrTony32: Thank you for checking for this new innovation. One thing I want you to know is that ups( uninterrupted power supply) can be used as inverter. It is what Many of us don't have the idea of on what the ups can do apart from the short time back it does.
Due to its good functionality and features many inverter nowadays have ups mode selefftionode you can switch on between to prevent interruption of power during power failure.
UPS has has some features and merit over sachet inverters. 1. It regulates voltage during fluctuation 2. It provides quality power to load 3. It provides constant voltage 4 it serves as isolation btw mains and load
How to turn it into inverter for use
Step 1 Unscrew the ups casing
Step2 Locate the internal connected battery(ies) and disconnect them ( if with two battries check if the batteries are connected in series it is a 24v ups which requires two battries compulsorly but if connected in parallel it is a 12v which can use either one or two battery .)
Step3 Those two wires of black and red are your positive and negative . Cut off heat and Strip the insulation part to use.
Step 5 Get a flex wire of black and red and connect to them togethe to extend wire length and tape with an insulation tape.
Step 6 Get any inverter battery of your choice of 45ah,75ah, 100ah, 200ah as u can afford and connect the wires from the ups to the battery and tighten properly.
Step 7 Get a battery charger to charge the battery and have it plugged on wall socket to charge the battery when there is power supply
Step 8 Now you good to go to power any appliances in your house.
Connect any load you want to use with it to the back of the ups socket
Below is a picture of mine
This can save you cost instead of buying inverter of high cost . It is cheap and affordable Suitable for a room , self contained , mini flat and 2bedroom flat. Is what use too. Total of this cannot cost you more 40k, 50k, 60k,70k depending your batterychoice.
based on limited capacitt it is Suitable for a room , a room self contained , mini flat and 2bedroom flat. . The total of cost of doing this cannot cost you more than 40k, 50k, 60k,70k depending your battery choice of capacity.
HOW TO KNOW THE CAPACITY OF INVERTER/UPS TO CARRY YOUR LOAD To do that you will need to know first the total load in your house. Supposed you have: 1. TV 50"....60w 2. Decoder ...25w 3.fan 62".....80w 4. 10 lights each 25w.x10=250w
Total power ...415w What is the capacity of ups/inverter to carry the load (415w)
We divide the the power load (415w) by one of the standardd power factor (0.8, 0.7,0.6) That will give us ...415/0.7 =519va
Therefore we will need 600va or 650va inverter/ups to carry the load.
Note that It is recommended to chose inverter/ ups bigger than the one we need.
HOW TO CALCULATE BATTERY BACKUP TIME. supposed we have 2 batteries of 200ah/12v and a total load 415w. How many hours will the battery last?
Firstly multiply the battery voltage by the amp hour. 200ah x 12v =2400wh x2 =4800wh Divide by the load ..4800wh/415w =11hrs.5min
Our backup time will 11hrs.5min but due to the battery can not drop to 0% to prolong the battery lifesspan we will maintain the battery DOD to 50% that will give us 6hrs.
HOE TO CALCULATE INVERTER /UPS CHARGING CURRENT.
Firstly find out the inverter vdc(voltage direct current) which is usually ranges from 12vdc-180vdc above
If my inverter/ ups is a 12v ( that is for one 12v battery) the charging current will be 10% of the battery ah. That is 10/100 =0.1 0.1x 200 = 20a.. Therefore a 12v inverter of any given capacity charging 200ah battery has about 20a charging current.
HOW TO CALCULATE CHARGING TIME that will be battery ah divide by charging current.
200ah/20a = 10hrs
HOW TO CALCULATE NO OF SOLAR PANEL FOR YOUR BATTERY suppose you have one 200ah/12v battery and u need solar to charge in the absent of power supply. It is simple. First know your battery charging current as calculated above 200ah battery charging current is 20a and the battery is 12v.
Power is v x a i.e 12 x 20 =240w
We need 240w solar panel to charge our battery Note it is recommended we use panel bigger than the one we need in this case we will need 480w panel for proper charging .
