Key Features for UK Residential Market
Dual input MPPT (>2kW PVI) to process two
strings independently so maximizing the energy
being harvested.
Wide input voltage range allows very short
strings to long strings.
The wide input range also allows the inverter to
start generating energy from the solar panels
very early on the morning to late in the day.
Maximum Power Point Tracking (MPPT) finds
the optimum working point to maximize the
energy harvesting.
Benefits
 Cater for different aspects (ie East and West)
 Different tilt angles
 Partial shadowing (chimney, trees)
 Different solar panel brands, ie;
MPPT 1 = 10 x 190W Brand X
MPPT 2 = 5 x 235W Brand Y

Key Features of the Aurora Inverters
 Dual MPPT on all Inverters above 2KW- this ‘two in one’ design means you can
have different aspect strings optimally managed by a single Inverter!!
 Widest DC input range of Inverters on the market and so maximizing PV
harvesting time
 Very Efficient – up to 96% Euro efficiency ( Max 96.8%).
 Best performing MPPT algorithm which tracks changes in 1.3 secs to 99.5%
 Optimum efficiency is seen in the mid voltage range – which is most typically
seen in string designs.
 10 year warranty with Trio 3 phase
 Light weight makes installation considerably easier.
