Solar Off Grid Inverter

    Rating
  • 500W to 100kW
 
Overview
Enertech Solar Inverter indigenously manufactured in Pune, India works by converting the direct current (DC) electricity from a photovoltaic array into alternating current (AC) and are perfect for household as well office use. The inbuilt solar charge controller is used for regularising the power flow. MPPT based solar inverter the firing angle is adjusted to get voltage output such that higher current at output is available for battery charging. Same can be discharged through the Solar Inverter to provide conditioned AC power to the consumers. Option is also available for battery charging with unique topology of solar charging having priority only in case of battery discharged to a pre-determined level and if solar is unavailable the mains grid will charge the battery to certain level leaving scope of further battery charging next morning when solar is available. This feature is provided to make maximum use of solar energy to minimize electricity bills.

The solar charger has a PF of more than 0.9 with protections such as overload, short circuit & reverse grid for the inverter. The solar inverter also comes with an auto DUSK ON facility to utilize maximum energy from the solar panel.

Solar inverter has an overall efficiency greater than 90%. An easy-to install and a cost effective solution which can cater to the growing power needs.

The single phase solar inverters comes in the range of 500 watts to 20 Kilowatts.

The three phase solar inverters comes in the range of 10 Kilowatts to 100 Kilowatts.

  • Pure sine wave output with low total harmonic distortion (THD)
  • High efficiency & high reliability
  • Pulse by pulse current limiting with auto-reset resulting in efficient overload and short circuit protection.
  • Battery pole reversal protection & battery deep discharge protection.
  • Noiseless in operation
  • When solar energy is sufficient then output of MPPT charger is given both to batteries & inverter, the output of inverter will give AC voltage to load.
  • When solar energy is weak then inverter is taking the possible DC source from solar in combination with batteries.
  • If batteries have low a voltage condition then load is shifted to mains grid & batteries are charging on solar output.
  • If solar energy is not sufficient to charge the batteries the mains grid charger will be active & DC voltage is given to batteries in combination with solar energy.
  • Once batteries are fully charged then load is automatically shifted to inverter & inverter is operating on solar & batteries
