  • Grid Connection An open letter to those on grid considering pursuing hydro power

    Many people contact us concerning the possibility of using a power source that is either connected to the commercial power grid or feeding power to a house that is. While this may be possible, it is not likely to make economic sense. Over 99% of our customers are off-grid and there are reasons for this. The question is then more like: ’Can I put in a small hydro system or should I spend ...

  • Performance of grid connected inverter with maximum power point tracker and power factor control

    Detailed analysis, simulation and hardware results of grid connected inverter with maximum power point tracker and power factor control in Malaysian climate are presented. A six-switch topology inverter with symmetrical pulse width modulation (PWM) switching technique is used. A low-pass filter is incorporated in the circuit to filter out unwanted harmonics and produce a sinusoidal AC current. ...

  • Controlling the number of on-grid multiple photovoltaic inverters to improve their conversion efficiency

    Two experimental PV-grid connected systems of 8.8 kWp and 36 kWp rating have been designed, installed and interfaced with Abu Dhabi utility grid. The PV arrays of both systems are interfaced with the grid via single phase grid-tied inverters. The inverters are installed in three separate groups that each injects 50 Hz electricity into one phase of the utility grid at the 0.4 kV level. The main ...
