Solar Panel Inverter Size Calculator

Sizing a solar inverter is an important part of any solar installation big or small.

Solar panel inverter size calculator. Please consult an accredited installer for precise details. An inverter must be used to convert the power in a dc only system to ac power. The size of the controller is then calculated as 1000 24 41 67amps a safety factor is then introduced and this is done by multiplying the value gotten by 1 25 this puts into consideration the variable power produced. I tried to use this calculator for sizing solar panels in hybrid system for micro gsm bts but size of invertor is too big for total load of 500 w.

As a general rule of thumb the size of your inverter should be similar to the dc rating of your solar panel system. Solar inverters convert the low voltage dc electricity created by your solar panels to the 120 volts ac electricity used by household appliances. No greater than 6 5kw worth of solar panels for a 5kw inverter. If you are installing a 6 kilowatt kw system you can expect the proposed inverter to be around 6000 w plus or minus a small percentage.

Inverters consume power as they convert dc power to ac power and in doing so contribute to the system load. For total load of 500 w with operational time 24 h per day calculator gives size of invertor about 555 kw. The less power an inverter consumes the more efficient it is which is how its efficiency rating is determined. How to choose the right solar inverter size for your solar power system.
