We are experienced, highly qualified, and discreet professionals in solar PV sector. We provide a customised solar design solution for residential and commercial solar as per requirements of the customer and DNSPs, and relevant Australian Standards and CEC design guidelines. We specialise in the design of grid-connected, grid-connected battery back-up, standalone / off-grid/ and hybrid system-solar plus diesel generator. In order to yield a maximum return on your investment, we always strive to design an optimum solution for our customers.
We have :
- More than 20 years’ of experience in solar PV
- Specialise in design and testing & commissioning of Commercial Solar.
- Complete engineering designing solution form commercial solar from grid connection approval to detail design to testing & commissioning to report preparation.
- POWERCAD software to check faulty level, grading study( discriminating and cascading of breakers).
- PVSyst simulation software for PV generation.
- In-house Registered Professional Engineer of Queensland (RPEQ ).
- Equipped with OMICRON Ponovo Universal Test System for Secondary Injection Testing of Protection Relay.
- Equipped with Fluke Power Quality and Energy Analyser for power qualiry test on HV and LV side.
- Service across Australia ( QLD, NSW, VIC and SA).
We have been providing our services to the solar companies across Australia to lodge the grid connection application and get an approval from DNSP across Australia such as Ausgrid, Endeavor Energy, Essential Energy, Jemena, Ausnet, Powercor, United Energy, SAPN, Energex & Ergon. In addition to grid connection approval, as a consultant we also provide the complete engineering solutions from site inspection to design to testing & commissioning. For every system over 30kVA, we carry out an injection testing of the central protection relay on site by using OMICRON CMC and Ponovo Universal Test System. Secondary injection test is required to ensure the relay trips as per settings programmed for under-voltage, over-voltage, under-frequency, over- frequency, ROCOF, vector shift as per the DNSP requirement. The central protection relay isolates the IES from the network in case of abnormal / faulty conditions. For system over 30KVA IES, in some cases, DNSPs also require the power quality test to confirm the network power quality is not deteriorated due to the installation and operation of the solar system. The PQ parameters such as harmonics, flicker, and voltage unbalance are measured before solar and after solar during power quality test. We use the Class A compliant Fluke Power Quality and Energy Analyser.
