Solar Module Cable and Accessories

MC Connector Cable and Accessories for Solar Modules 

We custom make UL Listed MC cable in any length . We make these in "loops" with a Positive MC connector on one end and a Negative MC connector on the other.  To figure your cost for the UL Listed assembly, simply multiply the number of feet required and add a pair of installed MC Connectors.

 These cables are NOT intended to be used as supplied, rather they must be cut either to length, or in the middle of the loop, for insertion into a combiner box or other appropriate connection.

Don't forget to order our impossible to find Stainless Steel cable clips to keep your module interconnect cables neatly connected to frames so they do not drop below the array. Stainless Steel Module wire clips will last forever, without corrosion. We don't recommend using plastic tie-wraps as they fall apart in sunlight in a very short time.

They are designed to hold one OR two USE-2 cables securely, with a specially designed tab to allow the use of a flathead screwdriver to aid in installation and removal of the clip.

Simply enter your MC Connector cable (USE-2) into the box, make your connections to your THWN-2 wiring using your choice of wiring methods (see picture) either DIN rail-mounted connectors (internal DIN Rail provided), Wire Nut Connectors or Weatherproof Butt Splices, and you're done.

UV resistant two piece shell with a special seal for water-tight enclosure. Appropriate for Roof Mount, Top-of-pole Mounts and Ground Mount installations.

 

 

Includes aluminum attaching bracket to mount box to the rack rail.

PV Low Temperature Over-Voltage Bypass Circuit Box

Protect equipment from high PV Open Circuit Voltage at Low Temperatures

Size the PV array for maximum energy harvest
Every PV array can now be sized without being limited by the high open-circuit voltages present at low temperatures. The Apollo Solar LTOB automatically switches modules out of the circuit if the temperature falls below the specified point.

Simple, Reliable Operation
The LTOB removes 1 module from the 6 module string keeping Voc under 140v. When the temperature falls below 10OC (50OF) the LTOB turns on and the top module is switched out of the circuit so the Voc drops to 120 volts. The 5 module string is below the 140volt limit down to -40O. When the temperature rises, the LTOB turns off and the module is switched back into the circuit.

Fast, Easy Installation
The Apollo Solar LTOB units are supplied with an adhesive tape on the back side. Just peel off the backing layer and stick the LTOB and Temperature Sensor to the back of the PV module to be cut from the string. Simply snap the MC connectors together. At normal or high temperatures the LTOB connects straight through and the PV array functions normally.

Features and Benefits

·         Automatically bypasses PV module at low temperatures to drop Voc.

	Expand the input voltage range of any Inverter or Charge Controller.
	Enables an extra PV module in every string.
	Use with any modules up to 85Voc.
	Any string voltage up to 600VDC.
	Switch up to 8 Amps per string.
	Choice of temperature switch point.

·         Complete safety at the lowest of temperatures without compromising the high temperature performance.

	Size arrays for maximum power and forget the cold/Voc problem.
	MC connectors - quick wiring.
	Failsafe to low voltage output
	Sticks to back of any module.
	Very low power consumption.

WEEB Grounding System Introduction                                              

Introducing the latest technology in grounding your solar array! Soon to be an absolute must for all PV systems! No more running ground wire to and from every module, and the sweetest thing is that the WEEB system is more effective!

WEEB stands for "Washer, Electrical Equipment Bonding". The WEEB family of products are used to bond solar modules to solar mounts. The mounts are then grounded so the entire assembly is grounded. The products use patent pending technology for bonding anodized aluminum surfaces together. Bonding PV modules to a mounting structure removes the need to wire the modules separately. Only the mounting structure needs to be wired to ground.

Why Should I Use it?

	Gives more consistent results than the method of scraping off the anodized coating by hand and using star washers.
	It saves you time!  ...No more running ground wire to every PV module.
	It's safe. ...Meets UL467 requirements for bonding/grounding systems.
	Its reliable. ...Patented design features stainless steel teeth that bite into anodized aluminum, providing a gas tight connection which prevents oxidation.

Grounding the entire array is now much easier! By simply mounting one WEEB Lug for each rail assures the teeth will penetrate into the aluminum rail. The lug itself is tin plated copper and the washer is stainless steel. The lug is a lay-in type, making it easy to attach the ground wire. Because you don't have to run ground wire to every single module, you save time and have a much cleaner installation. Neat!

Introduction to the parts needed

The WEEB-9.5 is a washer used to bond the frame of a PV module to a pole or ground mounting structure. The WEEB-9.5 has fingers which will hold the part in any 3/8 inch hole. This allows the WEEB-9.5 to be inserted at the mounting locations and stays in place while the module is aligned. When the hardware is tightened, specially designed teeth on the WEEB-9.5 embed into the module and mounting structure, making a gas-tight connection.

 nA variant part, the WEEB-9.5NL, does not have the fingers. This allows the part to be used to join structural pieces of a mounting structure where only a single fastener is used and allows bolts up to 3/8 inch in diameter. The fingers are not needed because it is relatively easy to assemble a single fastener with the WEEB, while for the case with modules, the large size of the module would make it difficult to position both the module and the WEEB. See the installation instructions for detailed pictures.

The WEEB-xMC(s) are used for rail-mounted modules. Retaining features keep the parts on the rail while still allowing them to be correctly positioned beneath the modules.

Rounding out the product family is the WEEB Lug, a two piece set of washer plus lug. The washer has specialized teeth for making connection through an anodized aluminum surface. The lug allows the lay-in connection of wire after the lug has been mounted.

Delta DC Lightning Arrestor                                                          

Don't forget lightning! If you have all those expensive modules on your roof or top of pole, that's alot of metal to attract lightning into your house. Most combiner boxes are made so that the PV - and + are isolated from ground. This enables you to install a Delta lightning arrestor at the combiner and bond the module frames, Delta and the combiner box to the ground stake at the bottom of you rack.

Lightning does what it wants but, if you make a good suggestion it may follow it, and keep it from entering your house. Call Tom at 888-826-0939 to discuss wiring this up.

We also carry AC and Hi Voltage Delta products Call with your needs
