4.4.5 Parallel Connection
Up to six identical units can be connected in parallel. When connecting MultiPlus-II units in parallel, the following requirements must be
met:
•
All units must be connected to the same battery
A maximum of six units connected in parallel.
•
•
Only identical devices may be connected in parallel.
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 MultiPlus-II units.
•
Place the MultiPlus-II units close to each other, but allow at least 10cm for ventilation purposes under, above and beside the units.
It is essential the negative battery terminal between the units is always connected. A fuse or circuit breaker is not allowed.
•
•
UTP cables must be connected directly from one unit to the other (and to the remote panel). Connection or splitter boxes are not permitted.
•
Always interconnect the negative battery cables before placing the UTP cables.
Only one remote control means (panel or switch) can be connected to the system.
•
4.4.6 Three-phase operation
The MultiPlus-II 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 (MultiPlus-II plus an optional control panel) will require
subsequently configuration (see Section 5).
Pre-requisites: see Section 4.4.5.
1.
Note: the MultiPlus-II is not suitable for 3-phase delta (Δ) configuration.
2.
When the AS4777.2 grid code has been selected in VEConfigure, only 2 units in parallel per phase are allowed in a three
phase system.
