In Enphase installations, the three-phase Q Relay (network system relay controller) acts as a galvanic disconnection device. It is designed for three-phase use and has built in contactors.
During specified grid abnormalities, the Q Relay disconnects the Enphase Microinverters from the AC grid, and when the voltages return to normal and the grid frequency is in the acceptable range, the Q Relay reconnects the microinverters to the AC grid. The Q Relay has built in current sensing that can detect DC current injection required by VDE V 0126-1-1 requirements.
The Q Relay works together with the Envoy-S to meet the need to break both line and neutral per grid requirements. See full installation instructions for the Enphase Envoy-S and/or Enphase Microinverters at: enphase.com/support. It is best practice to install the Q Relay when installing the Envoy-S and before commissioning the system. The Q relay is IP-20 rated. You must mount it in an environmentally protected enclosure.
Not required in the UK.

Eurener's 340W all black half cut panel is a high output and high efficiency panel. The Spanish manufacturer uses a highly developed fabrication process, including camera verification of welding, to ensure the high quality and consistency of the panels they produce.
As we're the premium partner for Eurener in the UK, these panels have an extended 20 year product warranty - a significant increase, at no extra cost to you - when bought from Midsummer.
These heavy-duty 200mm hanger bolts are suitable for fixing mounting rail to metal or corrugated cement roofs with steel supports, and come supplied with EPDM seal and two nuts, as well as a substantial steel or aluminium L-bracket. The bracket locks between the upper two nuts and is height adjustable.
The mounting rails are the core of the system. For each row of panels, a pair of rails is mounted horizontally on the roof and supported by rook hooks at no more than 1.2m intervals. The distance between the rails should be around three-quarters of the panel height. The panels are then laid on the rails and clamped in place with the end and mid clamps.
For long rows, simply join lengths of rail using the rail splice kits. Rails can be cut to length with a hacksaw or grinder.
These aluminium plates allow for the easy installation of solar panels onto slate roofs. The plates sit on top of the slate tiles and are fastened above the battens/rafter.
The Fastensol plastic tray can be extended using their mini 140mm rail. This allows panels of widths of up to 1140mm to be mounted in landscape configuration using these Fastensol trays.
Kit Includes:
1x Fastensol Plastic Tray
4 x 140mm Mini RailThis kit does not include:
Fastensol aluminium end clamps (4 per tray)
When fixing the 4x 140mm mini rails, you will need to drill additional holes on the side of the plastic trays.Please note that a lower ballast weight than the minimum weight on the datasheet can be used if stated by the ballast calculator
These substantial stainless steel brackets are used to secure the mounting rails to the roof beams. These are suitable for pan tile and concrete tiled roofs only.
To fit, a few tiles are removed from the outside of the roof and the hook secured to a rafter pointing 'downhill' with the tek screws provided. Plywood padding can be used to ensure the correct spacing from the tile surface. The tiles are simply replaced around the hook ensuring a weatherproof finish.
These standing seam roof hooks can be used to secure the mounting rails to the standing seams on a roof, with a "bulb" or "concealed" seam type.
You can then attach whatever you wish onto the hole on the top of the clamp.
Currently we do not have a solution in stock to attach this to Fastensol rails.
Triangle bracket for flat roof or ground mounted solar systems for panels in portrait orientation with an angle of 30 degrees.
This listing does not come with any screws, or cross connect clamps. Please select these separately, as these brackets can be utilised in a number of ways.
Dimensions: rail is 40x40mm in L profile with 3 lengths of 1410, 1350 & 720mm
Typically supplied either with:
Fastensol rail bolts to attach to  H-profile rail
With cross-rail brackets with hex nuts for attaching normal Fastensol rails.
Wood screws, metal screws, or hanger bolts, depending on your fixing requirements.
Mounting solar panels just got even simpler with this universal panel clamp from Fastensol. The clamp is spring loaded meaning that it is compatible with any panel from 30-46mm thickness. Due to it's clever design, it is also both a mid and end clamp in one - simply rotate the head 90 degrees either way to swap between either.
