UTL Solar String 4 Kw Grid Tie Inverter Price

UTL String (Grid-tied) solar panel system is simply a solar energy system that is connected to the electrical grid and, therefore, uses electricity from both the solar panel system and the electrical grid. If needed, the home can draw energy from the grid at times (such as on cloudy days or at night) when solar panels are not producing at full efficiency. Likewise, if more energy than is needed is generated by the solar panels of one home, that excess energy will be fed into the grid for use elsewhere.It will help to reduce our electricity bills and also reduce environment carbon emission.

Transformerless Inverter : Transformerless inverters are compact, light and relatively low in cost. Inverter efficiency is determined by the percentage measurement of energy convergence i.e. the closer to 100% of DC to AC.

Low Harmonic current distortion( THDi<3%) : Its improve the life of electronics appliances and also reduce the heating effect of system. Its improve the system power factor.

5 Years Standard Warranty : We have best in quality so that we provide 5 years on site warranty.

IP65 Certified : IP65 Enclosure – IP rated as “dust tight” and protected against water projected from a nozzle.

Onboard SPDs for DC & AC sides : Surge protectors (or suppressors) provide just that, a line of defense against surges, which are short-term high voltages above 110 percent of nominal. They are often associated with lightning strikes and utility switching.

Wi-Fi and Monitoring Application Available : WiFi Monitor is a powerful tool that allows you to watch the state of Wi-Fi networks and gather data about system parameters (power strength, frequency, consume power, etc).

Multiple Protection level : System have multiple protection level that’s makes system more reliable.

Efficiency : Maximum Efficiency over 98.6% , System provide maximum efficiency upto 98.6 %  , EU Efficiency over 98.2% , European or CEC Efficiency. The inverters or power converters don’t operate always at their maximum efficiency, but according to an efficiency profile as function of the Power. The “European Efficiency” is an averaged operating efficiency over a yearly power distribution.
