Solar String Optimizer
Installation manual

Warning
•Read the manual before installation
•The EnergyHub may not be opened by unauthorized personnel. Contact Ferroamp for
instructions.
•The electrical installation shall be performed by an authorized electrician in
accordance with electrical standards and safety precautions
•The warranty is not applicable if the products has been modified.
•Observe, the EnergyHub equalizes imbalance between the phase conductors and uses
the systems neutral conductor. Large imbalance causes large currents in the neutral
conductor.
•The DC contact shall not be connected when the EnergyHub is powered up.

2. Location of the SSO
•Make sure there is enough space around the SSO to enable a safe installation and
steady airflow.
•The SSO should not be located in direct sunlight.
•It is recommended that the SSO are mounted close to the PV-Panels.
Advantages:
•Increased safety since the SSO can disconnect the PV-pannels from the DC-link if a
failure occurs.
•The cables from each SSO can be merged together through a distribution board so less
cables are needed between the SSO and the inverter.
3. PV connection
•Connect the Sunclix-contacts to the cables. The one marked with a + to the PV+ cable
and the one marked with –to the PV- cable.
•Connect the Sunclix-cables to the SSO

EnergyHub is powered on.
•Connect the cables to the 3-pole DC contact as shown below. Please note the order of
the cables.
•Connect the cables to the 4-pole DC grid contact. Note that the Neutral (N) is not used
for the DC grid contact on the EnergyHub.
