Approximately 50 kilometers from Melbourne’s CBD in the beautiful Dandenong Ranges the environment is lovely, the air is clean but living up here does come at a price.
The electricity distribution system consists of poles and wires above the ground and this area is subject to a lot of blackouts and brownouts effectively from large trees or limbs falling on the wires.
The big storm
This became incredibly apparent in 2021 when a massive storm swept the area and a lot of houses were destroyed and some properties lost power for up to two months.
The customer and the system
The client is an animator and he works from home so the brief of this particular solar battery solution was energy at all costs.
The system that Greenwood Solutions designed and installed consists of:
- A PV solar array of 6.66 kilowatts
- That's 18 Canadian solar panels
- Each one of those panels accommodates a Tigo optimizer
- Tying it all together is a five kilowatt hybrid inverter from sungrow
- With 12.8 kilowatt hours of energy storage
Analyzing all of this is the Sungrow monitoring system.
How it works
With all solar systems the loads in the house are first serviced by the solar during daylight hours and if that's not enough the grid kicks in.
But this system is slightly different as there's something in between the solar contribution and the grid contribution and that is the energy storage component.
So loads in the house are first serviced by the solar if that's not enough then they're serviced by the batteries and if that's still not enough they're serviced by the grid. But in addition we've designed the system in such a way that a certain percentage of the energy storage is always there for backup because as I mentioned previously this area is notorious for brownouts and blackouts.
At the end of the day it’s all about finding out what the customers wants and needs, coming up with the right design and implementing.
