EnergyHub System
Installation and user 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.

Introduction
The EnergyHub is an inverter for the modular solar power systems, with new features. The
EnergyHub does not only convert direct current from PV-panels to alternating current, but can also
be used around the clock as an active electricity meter.
Adaptive current Equalization (ACE)
The patented ACE technology dynamically transfer energy between the phase conductors of a threephase system, thereby limiting the supply phase currents to the main fuse rating, without limiting the
load currents. This can reduce the required main fuse or increase the load currents, without
increasing the main fuse.
Figure 1 - ACE technology transfers available current from L1 and L3 to L2 so the loads in the facility can be utilized without
an interruption from the main fuse

DC nanogrid
The EnergyHub can be used with PV-panels and/or Energy Storage in order to utilize renewable,
locally produced, energy. This is enabled through the optimizers as they work as DC/DC converters
for solar power and Energy storages. The EnergyHub works as a bidirectional bridge between the
DC nanogrid, created by the optimizers, and the AC grid inside the facility. With this system, batteries
can be charged directly with solar power or with electricity form the AC grid, depending on the season
and weather. Accordingly, the EnergyHub is used both as a rectifier and inverter.
