About Hybrid Solar Inverter

In UTL Hybrid solar inverter is a multi functional inverter which combines the functions and capabilities of both grid-tie and off-grid solar inverters. A hybrid solar inverter is like an electronic heartbeat of a solar system that connects solar arrays to the utility grid and increasingly to the battery storage. One side, it stores the electricity into the solar battery for crucial times and on the other side, it will exports the excess or unconsumed electricity to the utility grid. The energy generated by solar arrays flows into the hybrid solar inverter where it will be converted immediately into alternating current (AC) to be uses in homes and supply to the grid.

A hybrid solar inverter provides all in one solution you need for solar with storage backup power. If you have an unreliable grid or if you want to lower your electricity bills or generate your own power then you should install a good quality hybrid solar inverter i.e. Sigma+ Hybrid Solar Inverter.

Sigma+ hybrid solar inverter is a premium quality hybrid solar inverter by UTL with an energy management system that intelligently calculates generation and consumption in real-time. It calculates the actual load for local consumption and stores the surplus into the batteries for later use. As day turns to night, the solar panels will cease to produce energy at which points your Sigma+ hybrid solar inverter will automatically fulfill the consumption within the house from battery stored energy. In case, your consumption exceeds what the batteries are able to supply then it will automatically switch over to the utility grid and continue to operate.

Sigma+ Grid Export Solar PCU

UTL hybrid Solar inverter has only one inverter named Sigma + Grid Export Solar PCU. It is solar power conditioning unit which is a single phase output solar inverter system. It works as a Bi-directional inverter which means power will be exported into the grid or power will be imported from the Grid.

The Sigma+ PCU work in two operates condition:

  1. Stand-alone
  2. Grid Interactive

Stand-alone: Solar Inverter operates from solar battery and produces AC output. The solar battery charged by solar power in first priority and from grid second priority.

Grid Interactive: Solar inverter operates from solar battery and produces AC output and also operates in parallel with the grid supply. Any excess solar power will be exported into the grid. Whenever sufficient solar power is not available to run the load, the required power is shared from the grid. The maximum power feed into the grid is depends on the system rating.
