Project Snapshot
Challenges
- Remote location
- No population – no amenities
- Extreme temperature conditions
- Product reliability and high performance critical
- Difficulty to access
- Difficulty to service
Solution
A 63kW PV array comprising of 252 Suntech STP250 solar panels is be mounted on Clenergy Solar Terrace II ground mount array frame with concrete footings.
The output from the array is fed to Kaco inverters acting as solar regulators; delivering their output to two paralleled banks of 60 Hoppecke 12OPzV1700 sealed lead - acid cells configured at 120 VDC nominal.
The batteries feed 3 x Selectronic SPLC 1202 inverters configured as a 60kW 3 phase inverter.
All power equipment is housed in a purpose-built insulated Colourbond power enclosure with the battery and power electronics separated by a lockable door. Ventilation to the battery area was via rotary roof vents.
The power enclosure is further protected by a separate tropical roof to give a separation and air movement gap. An air conditioner is fitted in the electronics room.
Outcome & Benefits
- Cost saving
- Reliable power
- Less reliance on diesel
