- Page 2 • 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.

Page 4: Introduction
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. - Page 5 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.

Page 7: Location Of The Energyhub
Location of the EnergyHub • Make sure there is enough space around the EnergyHub to enable a safe installation and steady airflow. • Mount the EnergyHub indoors or in a suitable enclosure with sufficient ventilation. • The wall and fasteners needs to be able to carry at least 25 •... -
Page 8: Current Sensor Installation
Current sensor installation • There are 3 available current sensors. The size of the current transformer is decided of the current flowing through the cable and its physical size. < 100 A, ratio 2000 < 160 A, ratio 4000 < 600 A, ratio 6000 Page 7 of 19... - Page 9 See wiring diagram in section 4 • The EnergyHub has an automatic calibration for each of the current sensors which handles the current direction and phase. • Observe. In order to facilitate the analysis and identifying different loads in the facility the sensor marked with 1 should be connected to L1, 2 with L2 and L3 with 3 •...
