Thanks my fellow solar engineer. The truth remains either 1kva or 3kva inverter, it's all the same. They all consume from prepaid meter. I have answered this question years ago when Nigerian power holding companies anounced about the introduction of prepaid meter. If you're using inverter on a prepaid meter, it means you're working for power holding companies and that of yourself. So I use to be plain to them. Solar is the answer. Thanks.
Every inverter has a resistance value which is relative to size, a 1kva inv will draw a 1kva energy equivalent on your prepaid meter, a 3.5kva for the same batteries will draw a 3.5kva equivalent energy on your prepaid meter thereby making you pay more when charging same battery
@@SeleniumTeck but doesnt the time to charge cancel it out? I have now idea, just wondering... lets say it takes 3 hours to charge at 1kw and 40 minutes to charge at 3.5kw... would that not be the same cost?
@@SeleniumTeck like wouldnt a 3kwh battery take 3kw to fully charge no matter at what rate? So will have to pay for 3kw no matter what if you charge via grid?
Your're theoretically right, charging is a function of Current and duration, however in reality with experiment, a 3.5kva 24v drains battery faster than a 1.5kva 24v at equal load. implication is you need more energy charging with a 3.5kva inverter than a 1.5kva at the same Load. Also note: more heat will be generated by the 3.5kva transformer compared to the 1.5kva inverter transformer.. Also in reality the difference in charging current in most inverters are not that much... Some 2.5kva inverter charges with 20Amps while some 3.5kva charges with the same 20amps. Just like I mentioned in the video different manufacturers produce inverters with different purposes
The simple truth is this, if you do not want to spent excessive amount on prepaid metre then, go for more solar grids. For example, if you have a 2.5kva inverter with 4units of 250watts solar panel, it is advisable you upgrade the number to 6units. This will enable the batteries charge much faster and in return, saves you money on prepaid. A 2.5kva inverter will draw a same size energy from your meter mostly when the batteries are flat but will start to drop the energy as the batteries get fully charged. Most people depend on solar for their inverters without bothering to charge with nepa. In most cases, if you must charge with alternative source aside solar, then get an external charger, charge with generator for 2hrs when your battery bank is low. Thank you
what you are saying is wrong ,your battery and solar panel should be at least 3 times great than your load,with that way your battery can easily get filled up
Solid content mate. Uve earned my sub👍🏽

Thanks for vid..no need for the music man👍
Pls Subscribe, like, & share ..
This information is helpful. Thanks for the update
the background music is too loud
Thank you
How does the inverter size impact the saving of costs? Like it would just charge tge battery way faster than a smaller inverter? Or what am i missing?

@@SeleniumTeck or does it now work like that? Im not an electrician or anyrhing, could be totally wrong? Thats why im asking

That is theoretically, in reality cost is a big factor to consider
