| 22 | Grid Tied Inverter: Supply, Installation, Testing & commissioning Grid connected solar inverter of suitable capacity of not less than 30 KW .1.Enclosure of all Thea Inverters are Aluminium Die cast. Aluminium Die cast Inverters are excellent in heat dissipation which reduces the thermal cycling of the components within the Inverter ensuring lower failure rates and a higher product life cycle.2. Only Tier 1 components are used for manufacturing of Thea Inverters. Please refer the make list of the components used in the BIS test report, you will find that all reputed brands are used which leads to less failure.3. Thea Inverters have Bluetooth as a standard which allows for easy communication, parameter setting, data collection and visualization.4. The thea web portal is an advanced platform through which a. We can have all historical data including voltages, currents, power energy,faults all stored for future reference. No other manufacturer allows for such detailed monitoring.b. Even the firmware updates can be done from the Thea portal thereby minimizing the time to roll out new firmware for enhanced performance and reduced failures.5. EMI and RFI filters are inbuilt in all Thea inverters, manufactures reduce the EMI / RFI filtration to reduce costs, but will cause damage to customer equipment in the longer run.6.The Inverters all come with inbuilt DC disconnect switches, manufacturers reduce the costs by removing DC disconnect switches which we do not7. We have Type II SPDs inbuilt in all three phase products which other manufacturers do not provide. This helps protecting the Inverter from damages related to surges and customers can install our inverters without Array Junction boxes. |
