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.

DUAL MPPT• Strings at different tilt angles.• Non uniform orientation.• Total module count is odd.• Subjected to different shadowing.• Different module types.

SINGLE MPPT• One string or array exceed the max

current/power of the single MPPT.• PV array is uniform and for cost

saving a single DC cable collects the power from 2 or more parallel connected strings.

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.

Maximize investment returns with Aurora!
