What are the Major mistakes of off grid system and  How to avoid , Mistake number- 03 Mistake Selection of Inverter 1) What is inverter? An inverter in an devise that converts the DC voltage to an AC voltage. In most cases, the input DC voltage is usually lower while the output AC is equal to the grid supply voltage of either 110 volts and 60 Hz, or 230 Volts  and 50 Hz depending on the country. There are different types of inverters based on the shape of the switching waveform . These have varying circuit configurations, efficiencies, advantages and disadvantages An inverter provides an ac voltage from dc power sources and is useful in powering electronics and electrical equipment rated at the ac mains voltage. In addition they are widely used in the switched mode power supplies inverting stages. The circuits are classified according the switching technology and switch type, the waveform, the frequency and output waveform. 2) Basic inverter operation The basic circuits i...

  What are the Major mistakes of off grid system and  How to avoid , Mistake - 02 The topic are made in 2 title basic and mistakes Charge controller Basic 1) Selection of Charge controller: What is a Charge Controller? A charge controller is a device controlling the charge by properly managing the current and the battery voltage. Charge controllers protect the battery and ensure the Photovoltaic System Efficiency to deliver longer life.  Solar charge controllers are rated according to the maximum input voltage (V) and maximum charge current (A). These two ratings determine how many solar panels can be attached, as explained in the section below ‘Sizing a solar charge controller’. Current Amp (A) rating = maximum input and charging current. Maximum Voltage (V) rating = Max voltage (Voc) of the solar panel/s. The Major mistakes below the last page 2) Where it is used? i) The charge controller is used  for charge the batteries.    they adjust the input po...

12 Major mistake of solar power Off grid system- Mistake-1

What are the Major mistakes of off grid system and  How to avoid , Mistake - 01 1) Selection of Panels is the major mistakes people are doing, the following factor to be consider while selection of solar panels a) Site weather or Climate condition Cloudy,  foggy, rain or snow : The site weather cloudy or more rainy the poly crystalline efficiency of solar power production will reduce around 80% poly crystalline panel it will not perform very well,  but we can select  Mono crystalline or Mono PERC panel which will produce higher power compare to poly crystalline.   b)  Determine solar panel efficiency and compare to industry Polly crystalline of around  16% and Mono crystalline  around 20  c) Check solar panel manufacturer warranties against industry average of   10-25 years d) Compare cost to relative efficiency – efficiency is important, but the most efficient panels aren’t always the best value e)...
