4.4.3 Parallel Connection
The Phoenix Inverter can be connected in parallel with several identical devices. To
this end, a connection is established between the devices by means of standard RJ45
UTP cables. The system (Two or more Inverters plus optional control panel) will
require subsequent configuration (see Section 5).
In the event of connecting units in parallel, the following requirements must be met:
•
A maximum of six units connected in parallel.
•
Only identical devices with the same power ratings may be connected in parallel.
•
Battery capacity should be sufficient.
•
The DC connection cables to the devices must be of equal length and cross-
section.
•
If a positive and a negative DC distribution point is used, the cross-section of the
connection between the batteries and the DC distribution point must at least
equal the sum of the required cross-sections of the connections between the
distribution point and the Inverter units.
•
Place the units close to each other, but allow at least 10cm for ventilation
purposes under, above and beside the units.
•
UTP cables must be connected directly from one unit to the other (and to the
remote panel). Connection/splitter boxes are not permitted.
•
Only one remote control means (panel or switch) can be connected to the
system.
4.4.4 Three-phase operation
The Phoenix Inverter can also be used in 3-phase wye (Y) configuration. To this end,
a connection between the devices is made by means of standard RJ45 UTP cables
(the same as for parallel operation). The system (Inverters plus an optional control
panel) will require subsequently configuration (see Section 5).
Pre-requisites: see Section 4.4.3.
Note: the Phoenix Inverter is not suitable for 3-phase delta (Δ) configuration.
