  • Page 6: Why Install Photovoltaic Solar Panels

    Locating the Unit Why Install Photovoltaic Solar Panels? Since the revisions to Part L of the Building Regulations in March 2014 there has been a need for a greater contribution from renewable sources of energy for domestic and commercial constructions. One way to comply with the updated regulations is by in- stalling Photovoltaic (PV) Solar Panels.

  • Page 7: Contribution To Running Costs

    PULSA PV installation manual Contribution to Running Costs The table below gives typical consumptions of standard electrical devices. Even when electrical devices are turned off they may still be consuming power. Photovoltaic Solar Panels can contribute towards the operation of these products with the contribution given being determined by the amount of panels installed.

    • Joule Pulsa modules do not need special cables for connection. All of the modules have permanent junction boxes, cables and connectors.

  • Page 13: Fire Safety

    PULSA PV installation manual • Under normal conditions, a module is likely to produce more current and/or voltage than reported under Standard Test Conditions (STC). Accordingly, the values of ISC and VOC marked on the module nameplate should be multiplied by a factor when determining the component voltage ratings, conductor current ratings, fuse sizes, and the size of controllers connected to the photovoltaic system.

Do not install the AC junction box without first removing AC power from the Enphase Sys- tem.

  • Page 23: Step 4 - Attach The Microinverters To The Mounting Rail

    • Position the Engage Cable to the right hand side of the centre of the panel so that connectors that are attached to the panels are not obstructed when fitting the Joule Pulsa panel to the mounting rail.

    Locating the Unit Electrical Installation Step 5 – Dress the Engage Cable Adhere to the following requirements: • Do not expose the connection to directed, pressurized liquid (water jets, etc.). • Do not expose the connection to continuous immersion. • Do not expose the AC connector to continuous tension (e.g., avoid pulling or bend- ing the Engage Cable near the connectors) •...
  • Page 25 PULSA PV installation manual • Place tie wraps on either side of the drop connector. Use one or two tie wraps, or other support scheme to secure the Engage Cable between connectors. • Remove and discard the temporary shipping caps from the Engage Cable.

  • Page 26: Step 6 - Terminate The Unused End Of The Engage Cable

    Locating the Unit Electrical Installation • Install sealing caps on all unused AC connectors. Unused AC connectors are live when the system is energized. • Do not use the shipping cap to cover unused connectors. The shipping cap does not provide an adequate environmental seal. Enphase sealing caps are required for protection against moisture ingress.
