The Inverter is the heart of any installation. We have a full range of inverters from Grid-Tie, Off-Grid, and full Hybrid Inverters

Grid-tied Inverters

Grid-tie inverters convert DC electrical power into AC power suitable for injecting into the electric utility company grid. The grid tie inverter (GTI) must match the phase of the grid and maintain the output voltage slightly higher than the grid voltage at any instant. A high-quality modern grid-tie inverter has a fixed unity power factor, which means its output voltage and current are perfectly lined up, and its phase angle is within 1 degree of the AC power grid. The inverter has an on-board computer that senses the current AC grid waveform, and outputs a voltage to correspond with the grid. However, supplying reactive power to the grid might be necessary to keep the voltage in the local grid inside allowed limitations.

Grid-tie inverters are also designed to quickly disconnect from the grid if the utility grid goes down. This is a requirement that ensures that in the event of a blackout or during load shedding, the grid tie inverter shuts down to prevent the energy it transfers from harming any line workers who are sent to fix the power grid.

Properly configured, a grid tie inverter enables a homeowner to use an alternative power generation system like solar or wind power without extensive rewiring and without batteries. If the alternative power being produced is insufficient, the deficit is sourced from the electricity grid.

Off-grid inverters

Off-grid inverters are designed to work as a stand-alone and cannot synchronise with the grid. They connect to the property in place of grid power and cannot work in conjunction with it.
Off grid inverters must supply power from DC to AC instantly to power the appliances. It must react quickly and up to and over the capacity rating of the inverter. It draws power from the battery, converts it from DC and outputs AC.

Hybrid Inverters

A hybrid inverter or smart grid inverter is a trending generation of inverter for solar applications using renewable energy for home consumption, especially for solar photovoltaic installations. Electricity from solar panels is generated only during the day, with peak generation around midday. Generation fluctuates and may not be synchronized with a load's electricity consumption. To overcome this gap between what is produced and what is consumed during the evening, when there is no solar electricity production, it is necessary to store energy for later use and manage energy storage and consumption with a hybrid (smart grid) inverter. The Inverter would generate AC directly from the PV panels and any access energy produced can be utilised to charge back-up batteries and even supply power back into the utility grid. This versatile unit will control all the energy needs and keep the system balanced. The essential loads will always be supplied first with power and when more power is generated by the PV array it will automatically supply the non-essential loads. The inverter also has a CT coil (current transformer) that can be programmed to allow feed back into the grid or use the access power to non-essential loads.
