RELINK - the company✓ Founded 2013 in Malta to develop an innovative range of Energy

Storage systems combined with Micro Inverters co-developed with a primary technology provider of PV conversion.

✓ RELINK relies on the wide and strong skills of its founders in the Energy and Renewables segments, in photovoltaic since 2007.

✓ RELINK has offices in:✓ Malta✓ Germany✓ Melbourne foreseen in 2016

3

RELINK - micro inverter technology✓ The unique RELINK technology has been developed with a

partnership with a world leader of Energy Conversion and the former R&D manager of a PV inverter leader.

✓ The RELINK micro inverters optimize the energy output of a PV module converting in the most efficient way the DC power in AC power available to the electric grid.

✓ The RELINK micro inverters offer an impressive value proposition for the PV systems.

11

RELINK - microinverter benefits✓ Longer life time and reliability

o eliminates components that represent main reason of failure getting a life time of 25 years.

✓ The best output powero Optimizes power for each module / stable over wide

temperature range.

✓ Increased safetyo Low voltage AC current, no high DC voltages, significant

reduction of fire hazard

✓ Simplified design and installation o Easy design due to independence of each/couple of

modules, minumum shade impact. No DC cables.

✓ Advanced monitoring systems o Accessible via Web, smart phone and tablet.

RELINK - the best convertion systemComponents with limited reliability, short life used in string inverters:✓ Electrolytic Capacitors and opto-isolators.

o the best electrolytic capacitors have an operational duration of about 7.000 hours @ 105°C.

✓ String inverter expeted life time 8 to 10 years.

The RELINK technology has superior performances: ✓ Does not use components with limited life time.✓ Improves the stability and the Maximum Power Point Tracking (MPPT). ✓ The life time of a RELINK micro inverter is more than 25 years.

o Uses innovative capacitors with operational duration of about 21.000 hours @ 105°C. (3 times more than string inverter)

14

RELINK - real case in Australia 2,2kWp✓ Difficult roof for string inverters

due to double shade.

✓ Professional PV installer should not install a string inverter in this situation.

✓ RELINK micro inverters offer best solution by reducing shade impact and maximising energy output

15

RELINK - real case in Australia 2,2kWp✓ The increased PV

system energy production ranges from:

✓ Min + 5% w/o shadeo more MPPTo no mismatch

✓ Up to + 30% with shade

Shaded modules have no impact on overall performance of the system
