1GENERAL INFORMATIONS
1.1 About Solar Eclipse
Solar Eclipse totally works in DC and the only energy needed is from the sun!
Solar Eclipse is the smarter way to take advantage of all the energy produced by your PV plant (see picture
no. 1).
It stores electricity overproduced by the photovoltaic modules even before it arrives at your inverter,
charging standard batteries of any type (lead, gel, lithium, etc.) in DC, to re-use it when needed (at night or
in poor sunlight moments), making you inverter behaving like a sun irradiated panel!
Solar Eclipse totally works in DC and does not need external power supply, the only energy needed is from
the sun!
Figure 1 - Solar Eclipse

1.2 How the Solar Eclipse works
When the PV modules power exceeds the power required by the loads of the house, Solar Eclipse feels,
through the network sensor, that there is an electricity grid connection and begins to store energy into the
connected batteries.
On the contrary, when the power required by the loads of the house is higher than the one produced by
the PV modules (for example if it is cloudy or at night), Solar Eclipse picks the energy stored by the batteries
up and provides it via the inverter. Solar Eclipse works as a battery charger when the solar power is in
excess, and as a solar module string irradiated from the sun when the solar power is not sufficient or it is
totally absent.
This allows the inverter to deliver only the power required, minimizing unnecessary entries or withdrawals
from the grid.
Solar Eclipse complies with the following rules:
• No batteries charge through grid energy
• The available energy from the PV modules is used to power utilities
• The excess energy is used to charge the batteries
• The further energy produced by the plant is sold to grid network.
• Battery power used only if the sun is not enough to power utilities, or at night
1.3 Manual use

NOTE: To prevent electromagnetic disturbances generated by power cables from generating
"bounced" voltage, current and frequency readings of the Power Meter, always wrap the
signal cables on dedicated cavities and appropriately separate, trying to avoid wiring lengths
greater than 100 meters.
NOTE: In the presence of electromagnetic disturbance, the voltage and frequency values
detected by the Power Meter could be "bumped" and this could cause the Solar Eclipse
"block" status, which detects network parameters outside the admitted range.
•Prepare the grid sensor wire with a three-pole
terminal using an UTP twisted pair cable or a
shielded STP twisted-pair cable with a minimum
0.25 mm square section (see image below).
WARNING: If the inverter has no isolating
transformer, double insulated signal cables
(double sheath in polyethylene) should be used
and do not ground any screen stocking.
•Use two pairs of twisted wires, making sure to connect the central PIN (O) to both pairs as shown
in figure 4. In the case of STP shielded cable, connect the braid to the central PIN (O),
remembering to insert the PG9 and note the color of the wires.
