The M215 solar microinverter offers a weighted power conversion efficiency of 96% (CEC), according to the company. Featuring an output 13% higher than previous versions, the microinverter is compatible with 60-cell modules. Standalone and AC module (ACM) models feature CSA certification. The ACM model speeds installation by eliminating the need for rack mounting, a separate system ground wire, and DC cable management.

Development Kits

The C2000 Solar Developer’s kit is a high-voltage, string-ready isolated MCU-controlled product comprised of two development boards. This kit provides a dual-controller design, allowing users to work with high-voltage power stages and inter-processor communications systems. The primary board features a 300VDC compatible input stage supporting up to 500W. The secondary board features a full bridge DC-AC inverter supporting 120/220VAC output. The C2000 Solar Explorer low-voltage kit supports the company’s Piccolo and Concerto C2000 MCUs. This kit includes multiple DC-DC conversions as well as a DC-AC state that supports 12VDC/100W input stage. Other features include a single-switch DC-DC boost for MPPT, DC-DC SEPIC for battery charging and a full bridge DC-AC inverter capable of driving 24VAC.

Multi-Pin Connectors

Solar SPEC Pak multi-pin connectors meet the requirements specified in UL 6703A. The connectors offer power handling capabilities up to 1,000V and feature a locking latch that complies with 2008 NEC section 690.33(C) requirements. Designed for wire-to-wire applications, the products are capable of handling up to four individual lines, which reduces the number of traditional connectors needed in solar applications.

Combiner Box

The Hoffman solar combiner box is available in Polypro and 14-gauge mild steel models. Non-metallic Polypro material is non-glass-filled polyester that offers a combination of corrosion, impact, chemical, and UV resistance, and protects against wind and moisture. Polypro boxes provide an overlapping tongue-and-groove raised cover and gasket for a secure seal and are Type 4X-rated. Mild steel models feature continuous hinges, oil-resistant gaskets, and a Type 4 rating. Both versions are available in 6-string and 12-string configurations and include touch-safe fuse holders with a non-load break rating to 30A max.

Mounting System

The Evolution FR flat roof system features fiberglass baskets and rails as well as tool-less pivot clamps constructed of 16-gauge 304 stainless steel. According to the company, the fiberglass components are corrosion-resistant, and there is no thermal expansion. Featuring a universal design, the product requires no roof penetrations.

Grounding Connectors

The SGB-4 and GBL-4SS connectors for solar panel grounding prevent galvanic reactions and enhance conductivity. The SGB-4 connector body features a clamp-on design as well as extruded serrations for breaking the anodized finish on photovoltaic (PV) modules and frames. The serrations in the wire binding break corrosion on the grounding wire, eliminating surface preparation for the PV module, frame, or ground wire. The UL 467-listed and CSA-certified aluminum connectors accommodate 4 AWG to 14 AWG and are dual-rated for copper or aluminum conductor. In addition, they are electro-tin plated for low contact resistance, and a lay-in feature facilitates installation.

Grounding Clamps

Approved for portrait orientation use with the company’s Arista Monolithic commercial rooftop racking system, these module clamps with integrated grounding feature Weeb washers that use “teeth” designed to break the anodized layer of the module frame and provide a gas-tight connection. According to the company, this eliminates oxidation and provides a reliable bond to ground the racking system and PV module. The clamps also eliminate the need to use separate ground lugs and copper wire between each module and are ETL-listed to UL 467.

The Enphase Energized AC Module (ACM) combines the company’s solar modules with Enphase microinverters. The microinverters easily attach to the frame of the 60-cell module to generate grid-compliant alternating current (AC) power directly at the module-level. Constructed of ethylene-vinyl-acetate, the modules feature a weather-resistant frame and durable glass surface that is field tested to support more than 300 kg (660 lb) of load per square meter (10.7 ft2).

Mounting System

Made of 100% recycled material, the Ecofoot solar flat roof mounting system uses a green industrial-grade polymer to eliminate the need for grounding and the potential for corrosion. The universal design adapts to all PV modules and challenging roofs without the need for customization or roof penetrations, according to the company. An optional deflector reduces total install weight and is engineered for high wind zones.

The E-Force 1MW, air-cooled solar inverter has received ETL certification to UL 1741-2010 and CSA C22.2 No. 107.1 standards. Designed for grid-tied large solar applications, the unit integrates two 500kW inverters in a single enclosure, which the company says can reduce the skid footprint by as much as 30% compared with independent 500kW competitive inverters. In addition, the units achieve peak and CEC efficiencies of 97.9% and 97%, respectively, with total current harmonic distortion of less than 5%.
