Note : Bidders should submit the make & Model no. of PCU with technical Bid. All the required test reports &

Manufacturer authorization for providing the support with all the spares for 5 years are to be

submitted with the bid.

SPECIFICATIONS OF POWER CONDITIONING UNIT (PCU)

The Power Conditioning unit mainly comprises of MPPT based PWM Solar Charge Controller and a Single

phase bi-directional inverter.

The MPPT Charger is a microprocessor based system designed to provide the necessary DC/DC

conversion to maximize the power from the SPV array to charge the connected battery bank. The charge

controller is equipped with necessary software that allows precise charging of the battery bank. Many

protection features are also included to ensure that no abnormal or out of range charge conditions are

encountered by the battery bank. The system incorporates a front panel LCD display with LEDs and a

switch to indicate the “operational status” and “fault status” of the system, reset system faults and

implement various operating modes.

BASIC SYSTEM OPERATION

‘Full Auto’ mode

• Under defined/light load conditions and with the battery in a “Full State of Charge” the available

solar power will supply the site load via the inverter.

• Under medium and heavy load conditions above the defined load, all available solar power is used

to power the load as well as to charge the battery. The balance of power needed by the site load is

provided/shared by the grid.

• In the event of low solar power being available or Battery Bank reaches at predetermined low level,

the PCU configures itself as a charger and the grid commences charging of the batteries in addition

to supporting the site load.

• Once the batteries have reached a predetermined level of charge all the available renewable energy

will be utilised to power the site load and reduce the power drawn from the grid.

• In the event the grid supply was lost or moved too far out of its nominal range, it will be

disconnected and power to the load will be supplied from the battery and any available renewable

resources.

• Once the grid supply was detected to be back in range and stable, the inverter module connected

back in parallel with the grid supply to power the load.

SYSTEM FEATURES AND OPTIONS

• Full automatic operation with no break to the supply during transitions from inverter+ grid to

inverter only operation.

• Output voltage conditioning when operating in grid interactive mode to ensure stable and reliable

supply to the site loads.

• The Peak load shaving (PLS) feature is available which utilizes batteries based on battery state of

charge (SOC) thus optimising grid usage. PLS feature provides for extending battery life as the

battery is discharged under controlled conditions. of 30.


• Renewable resources are fed directly to the site load via the inverter as much as possible to

minimise losses due to battery inefficiency.

• Capable of being integrated with renewable/distributed generation sources on both the AC and DC

bus.

• Local LCD (liquid crystal display) and keypad for system control and monitoring instantaneous

system data.

Important features/protections in the PCU:

• MPPT included.

• LCD keypad operator interface menu driven.

• Automatic fault conditions reset for all parameters like voltage, frequency and/or black out.

• MOV type surge arrestors on AC & DC terminals for over voltage protection from lightening induced

surges.

• PCU operation from 0° to 55° C,

• All parameters shall be accessible through an industry standard communication link.

• Over load capacity (for 30 sec.) shall be 150% of continuous rating.

A. Cabling Practice: Cable connections shall be made using PVC Cu cables, as per BIS standards. All

cable connections shall be made using suitable terminations for effective contact.

B. The PCU shall include an easily accessible emergency OFF button located at an appropriate position

on the unit.

C. All doors, covers, panels and cable exits shall be gasketed or otherwise designed to limit the entry of

dust and moisture as per IP 21.

D. In the design and fabrication of the PCU the site temperature 5° to 55°C, incident sunlight and the

effect of ambient temperature on component life shall be considered carefully. Similar

consideration shall be given to the heat sinking and thermal for blocking diodes and similar

components.
