2KVA inverter

                            welcome to super green energy tech.blogspot.com

                                                   Good home made inverter

Hello ever one welcome to my blog I will like to introduce to you my home made inverter.

Most people think that home made inverter are not reliable thy may have had some ugly experience about a home made inverter in the past but the truth is that every inverter is base on some one idea and how well the person understand the technology is what will determine how good his inverter will perform.

I have been building inverter for years and I have been working herd to understand it better and to improve on what I already know I have had up and down situations in the past but all thanks to God today am doing great.

                                              What are the challenges in some inverter

There are many things that can make an inverter not to perform well.

(1)   Frequency. if the output voltage of the inverter do not have a good frequency it can create a humming sound in an inductive load and it can make an inductive load to work on a higher amps and there by making it to generate much heat and get burnt.

(2)   Low batter cut off. If the inverter do not have a low battery cut off  it can drain down the battery to an extreme low voltage and there by reducing the life sperm of the battery.

(3)   Under Charging. If the inverter has an inbuilt battery charger that is under charging the battery or the charging current from the inverter is too poor the inverter will take a much longer time to charge the battery and if such a long time is not giving the battery will always be under charge and this will reduce the life of the battery.

(4)   Over charging of the battery. If the inverter charging current is very good then  there should be a battery full cut off circuit or a circuit that can reduce the charging current of the inverter and keep the battery on a float voltage otherwise the battery will be over charge and over charging of a battery can reduce the life of the battery.

(5)   Overload. If you overload an inverter it will over heat the inverter circuit and create a damage in the inverter this is why all inverter must have an overload protection circuit or a reliable  circuit breaker.

      the inverter in the above picture is my 2KVA 24V DC input inverter with inbuilt battery charger with built in automatic change over, the automatic switching from mains to inverter mode or power back up mode of this inverter is as fast like a UPS.

                                                    technical parameters 

1. system DC input voltage.......................................................24V

2. system AC output voltage.....................................................220V

3. mains input.......................................................................... 200V to 230V

4.battery low voltage cut off.................................................... 20.5V

5.battery full cut off voltage......................................................29V

6. over load warning alarm at...................................................1300W load

and cut off after 10 to 15 seconds 

7. over load cut off at .............................................................1800W and above

8. red color low battery indicator bulb.

9. green color battery full indicator bulb.

10. orange color mains indicator bulb.

11. red color over load indicator bulb.

12. charging current / load capacity meter.

13. DC input voltage meter.

14. AC input voltage meter.

15. DC input circuit breaker.   

16. AC input circuit breaker.

some one may ask if the inverter is 2KVA why is the load delay cut off at 1300W?

it is because i don't think it is a good ideal to load any appliances to its maximum capacity and the user may not be able to calculate the amount of load he or she is using that is why i design the inverter overload delay cut off at 1300W and instant cut off at 1800W this will make the system on its own to manage the amount of load you are using.
