  • Page 20 RACKING TILE ROOF INSTALLATION Note: The tile roof interface is only suitable for installation on timber rafters. 1. Determine and mark the position of the tile roof interfaces according to your plans. Remove the roof tiles at marked positions or, if possible, simply move the tiles up slightly.
  • Page 21 RACKING 6. For thin tiles (such as slate, shingles), a portion of tile must be cut and removed from the tile above the tile roof interface, creating a recess. Suitable flashing must then be installed around the tile roof interface, with an overlap of at least 150mm at the edges of the recess.
  • Page 22 RACKING TILT LEG INSTALLATION Note: Screws supplied with the tilt legs are wood screws suitable for timber only. Screws used in metal purlins must be suitable for metal structures and have a TPI (threads per inch) of 14. 1. Determine and mark position of feet according to your plans.
  • Page 23 RACKING RAIL INSTALLATION 1. Install rails onto the roof interfaces. If the assembly consists of rails of different lengths, always begin with the shortest piece. Install the rail loosely onto the roof interfaces using the Allen head bolt, washer, retaining washer and Z-modules supplied (2 to 3 turns of the bolt are adequate for loose installation).

  • Page 24: Rooftop Isolator

    ROOFTOP ISOLATOR When installing the rooftop DC isolator, a Solahart Rooftop Isolator Subassembly must be used and must be mounted to the rail by following the steps below. To help prevent UV degradation, the Rooftop Isolator Subassembly should be mounted as far from the north side of the array as possible.

  • Page 25: Wiring

    (i.e. do not connect or disconnect plug connectors under load conditions). Only use plug connectors supplied with your Solahart PV system, or which are the same type/model and from the same manufacturer as those on the PV module. Ensure that all plug connectors and plug wiring are in good electrical and mechanical condition and are not subjected to mechanical stress.
  • Page 26 WIRING DC ISOLATOR WIRING The DC isolators utilised in Solahart PV Systems are not polarity sensitive (non polarised type) however for uniformity they should be wired as shown in the DC isolator wiring diagram below. Warning: DC isolator terminal screws must be tightened by hand only. Do not use power tools.

  • Page 27: Power Optimizers (Solaredge Only)

    Determine and mark the power optimizer mounting locations on the rail: a. Power optimizers should be spaced approximately 1009 mm (for REC280TP) or 1015mm (for REC290TP2) apart on the rail. See figure below. b. Power optimizers must be positioned so that they maintain a 25 mm clearance distance between the power optimizer and other surfaces to allow for heat dissipation.
  • Page 28 POWER OPTIMIZERS (SOLAREDGE ONLY) Attach each power optimizer to the mounting rail using the Z-module assembly provided in the BOS kit. See figure below. Apply a tightening torque of 9.5 Nm. Z-module assembly Note: It is recommended that the power optimizers be placed face down to ensure clearance between the back of modules and power optimizers.
  • Page 29 POWER OPTIMIZERS (SOLAREDGE ONLY) Ensure the Rooftop DC Isolator is in the OFF position, strip 12 mm of insulation from the end of each extension lead and connect the two extension leads to the Rooftop DC Isolator terminals. The Rooftop DC Isolator should be wired in a consistent manner.

  • Page 30: Pv Modules

    The Solahart mounting system requires the use of modules of equal thickness for correct clamping. Note: Ensure only modules of the same type (model & thickness) are clamped side-by-side and electrically connected.
  • Page 31 PV MODULES The following procedure should be adhered to whilst wiring module strings to prevent the risk of electric shock or inadvertent short circuiting of live cables whilst wiring the Rooftop DC Isolator: Two extension leads per string should be constructed using the DC extension cable provided in the BOS Kit.
  • Page 32 PV MODULES Warning: Only Solahart approved earthing plates are to be used. Warning: Module frames must be located on top of earthing plate earth bond protrusions. Warning: Earthing plates are intended for single use only and must not be reused.
  • Page 33 PV MODULES Module Mounting Procedure 1. Mid clamps and end clamps can be inserted into the rail by following the procedure shown, making sure the spring washer is correctly in place. For easy use of Z-modules, ensure Allen head bolt threads do not project through lower side of Z-module, so the Z-module is free to move along the rail.
  • Page 34 PV MODULES 7. Place an end clamp into the end of each rail. Ensure that the end clamps are tight against the module and are at least 25 mm from the rail ends. In positions where earthing plates are required, ensure the frame of module is located on top of the protrusions of the earthing plate.
