Important:
It is recommended to label both ends of each cable with the appropriate tenancy name (e.g. Unit 21) and
SolShare output name (e.g. R1 or W4, etc.) to ensure the correct cable is wired into the correct tenancy in
the main switchboard.
Important:
For maintenance and troubleshooting purposes, it is requested to write the tenancy names corresponding
to each output on the bottom plate of the SolShare (with permanent marker).
Important:
SolShare must have output connection (with grid connection) to R1, W1, B1 for correct operation.
If possible, wire these to common power connection.
Important:
Check the order of the SolShare outputs carefully. The SolShare terminal block is configured to wire in
the order R1, W1, B1, R2, W2, B2, R3, ... etc. Ensure the connections from the Tenancy Main Switches
(Inverter Supply) via any SolShare Maintenance Isolators (Grid) are connected in this order. Ensure the
switches are labeled clearly and logically.
Follow these steps to complete the output wiring:
1. Complete the Unit Connected column of the Commissioning Document on page 6, allocating a SolShare output
to a unit/apmt number.
2. If using SolShare Maintenance Isolators (Grid): Cut output power cables to appropriate length to reach from
SolShare Maintenance Isolators (Grid). Label both ends of these cables with the tenancy number.
3. If using SolShare Maintenance Isolators (Grid): Run cables between SolShare and SolShare Maintenance
Isolators (Grid). Terminate cables to appropriate SolShare output connectors as per the configuration in step 1.
4. Cut the power cables to appropriate length to run from the SolShare Maintenance Isolators (Grid) to the Tenancy
Main Switches (Inverter Supply) in the Main Switchboard. Run and terminate these cables.
Warning:
Only one neutral and ground shall be wired out of the SolShare, as shown in the diagram on page 14.
Output neutral and ground must be wired to main neutral bar and main earth bar respectively, located in
the main switchboard.
Warning:
- Ensure the phase of the solar supply correctly matches the phase of the unit’s supply from the grid.
- Additional circuit breakers must be sized to perform overload protection for SolShare output cables.
- The solar system max output must be less than the main circuit breaker rating of every connected unit.
- The neutral for the SolShare must be wired directly to the main neutral bar inside the main switchboard,
i.e. at the MEN link.
-
Point of connection of solar should be on the service side of tenancy main switch unless specified
otherwise by your Project SLD.
