Irradiance Meter

The Survey 100 irradiance meter uses a precision PV cell sensor for highly accurate irradiance measurement, displaying results in either Wm-2 or BTU/h/ft2 and making it suitable for both solar PV and solar thermal site installations. The device also incorporates a digital compass, digital tilt meter, and dual-channel precision thermometer. These features allow users to quickly identify the location where maximum levels of solar power can be collected and accurately measure irradiance, roof pitch, orientation, and ambient air/PV module temperature. Battery-powered, the instrument incorporates a display hold feature that enables site readings to be captured in difficult locations.

Combiner Box

The Solarlok is a 5-string input, plug-and-play combiner box for residential PV systems. Offering a simple 4-step installation process, positive and negative PV input string connectors plug in on the outside of the box. Internally, the box is prewired so that each input string can be fused up to 15A and combined in parallel to a single output. Four ¾-in. knockouts allow output conduit to exit in any direction. Additionally, each input string can handle a PV short circuit current up to 9.6A.

DC Connectors

Designed for solar junction boxes, field installations, and photovoltaic (PV) grid wiring, SolarSpec DC connectors are IP67-sealed. The connectors feature an internal locking mechanism that prevents accidental or unauthorized decoupling of the connector during service in the field. With contact resistance of less than 0.5 mΩ, the contact can handle 30A and accommodates 2.5-mm2 and 4-mm2 to 6-mm2 
(14 AWG and 12 AWG to 10 AWG) cable. In addition, the products remain fully sealed when mated and feature an enhanced strain relief design.

Inverters

With a power range of 3.3kW to 8kW, PVS300 solar inverters feature an intuitive control unit equipped with a user-friendly graphical display that provides sun meter, solar energy production information, and help/settings menus. A built-in data logger displays and stores the exact daily, weekly, monthly, and yearly production up to 
24 yr. In addition, the display can be detached from the inverter and mounted on a wall to monitor inverter performance from outside the installation room. An in-built microprocessor monitors internal protection devices and immediately transmits error messages or information to the inverter display and optionally over the Internet as an email in the event of a problem.
