How does the Giraffe 2.0 work?The Giraffe 2.0 is a hybrid power station ready to charge anything from your e-vehicle to your home – by capturing energy of the wind and sun.
This futuristic yet natural construction comprises a wooden structure supporting solar modules as well as a wind turbine.
Intelligent positioning of PV panels in 24 different angles allows for stable energy production – providing solar energy
PV mounting
The Giraffe 2.0 is normally equipped with a 3.5 kW wind turbine, but can have a 1.75 kW solution instead
The solar panels provide power capacity of 6.0 kWp.
Giraffe 2.0: stable energy productioncomplementing solar with wind power
The Giraffe 2.0 is able to produce up to 13 800 kWh per year even in countries with lower solar radiation and moderate winds – providing power 24 hours a day, all year round

InnoVentum’s Giraffe 2.0 offers attractive warranty conditions for PV panels included in the installation:
The Micro Inverter System has revolutionized the solar industry's approach to small- and industrial-scale installations. By distributing power conversion technology into the array(s), photovoltaic systems
- No system-wide point of failure- - - Increased safety with no HVDC- Conduct detailed performance analyses- Detect issues automatically- Take advantage of remote diagnostic tools- Proactively plan for maintenance instead of reacting to central inverter emergencies- Accelerated system installation time- - No need for procurement of specialized HVDC component parts
Micro Inverters

Micro vs. String InvertersSolar systems are constantly affected by environmental factors, such as shade, dust and debris. Using a traditional string inverter means that everything is wired in series, and the lowest performing module determines the performance of the entire series. This is commonly known as “The
energy production of the system.
Micro inverters allow each solar panel to operate
performance of the entire system (20% increase on average).
The ability to diagnose module issues remotely, precisely, quickly, and easily over the life of the PV installation results in
capabilities, as well as the ability to claim module warranties easily where appropriate.
standard. A micro inverter solution proposed by InnoVentum offers a 20 year warranty! Each micro inverter installed on a PV panel is working at low voltage, lowering the risk of failure.

Giraffe vs Giraffe 2.0 – Stronger & More Durable
Higher strength thanks to glulam enabling a bigger rotor turbine
Less reinforcement / wood needed to achieve higher strength
giving the 2.0 a more harmonious design
Stronger with less metal:long GL beam replaces bolt assembly.
Connections are less complex and more robust
