Tender to Empanel Firms For Supply of Grid-Tied, Off-Grid, Hybrid Solar Inverters

The Center for Development of Imaging Technology (C-DIT) has floated an empanelment tender seeking agencies to supply grid-tied, off-grid, and hybrid solar inverters for its solar projects in Kerala.

The last date for the submission of bids is November 24, 2020. C-DIT did not specify an earnest money deposit (EMD) for this tender. The tender form costs ₹1,180 (~$16).

The tender is invited from the manufactures, authorized distributors of battery models empanelled with the Agency for Non-conventional Energy and Rural Technology (ANERT) as an original equipment manufacturer (OEM). This list includes solar inverters of Growatt, Sungrow, Fronius, Evolve Energy, Huawei, SolarEdge, Hykon, Studer Innotec, and Enertech UPS.

C-DIT said that the power conditioning units (PCU) must be string inverter with the facility to export power to the grid. All on-grid inverters must include appropriate self-protective and self-diagnostic features to protect it and the photovoltaic arrays from damage in case of a component failure.


Off-grid PCUs must have a charge controller that is integrated with the inverter or as a separate unit.

Notably, ANERT recently invited bids from empanelled agencies for the rate contract of 10 MW of solar power projects in Kerala.

Hybrid inverters must be string inverters with the facility to export power to the grid. All the PCUs used in solar projects must come with a five-year on-site warranty, which is to be provided by the equipment manufacturer.
