Eyre Peninsula, South Australia
The client brief was to design a Stand Alone Power System (SAPS) which would service a brand new home with a 18Kwh daily demand, and be totally Solar PV on ground mount adjustable tilt.
The Design Process:
The tailored ground mount frames were built using local expertise, with a prototype being build prior to the project commencing. Once tested and modified the frames were built and ‘flat packed’ to the site.
A 5.6Kw of solar PV [REC Panels] ground mount array, consisting of x6 sub arrays with a site specific 3 position adjustable tilt angle [solstice/equinox] incorporating AC coupled [SMA inverters] and a parallel 5.5Kw petrol generator [Honda] backing up a 48 volt 1600 ampere hour battery [RAYLITE] with 5 days autonomy and remote monitoring.
All situated in a purpose built control room 30m from the house.
A SAPS which has delivered on all levels to the point where it is able to support a 2.5kw air conditioner run as required.
Battery daily depth of discharge is around 15% [seasonally adjusted], with the generator being called in only every 180 days to do the battery equalizing charge.
