Planetary Gearing For High Reduction Ratios
For high-torque, low-output speed gearmotors with self-locking capabilitIes, Wormetary gearing features integral-control capabilities ranging from four-quadrant digital speed or positioning to master electronics, including CANopen, Profibus and EtherCAT fieldbus connectivity. The brushless DC motors combine right-angle worm gearing to turn the corner with a planetary gearbox for reduction ratios up to 35,000:1 and peak torque capability up to 320 N-m (2,832 in-lbs) at an overall ratio of 80:1.

Electric Design For PV Systems
Helios 3D Electronic Extension adds to Schletter’s system planning software by handling nearly all aspects of electric design. Users can create device hierarchies, specify them with real devices and make string definitions. Users can also create trench structures, connect each to device areas and assign them to the fields. The software then assigns the string definitions to selections sets. It also places combiner boxes with wiring schematics and appropriate cable lengths.

New Multi-Pole Mount G2
The Multi-Pole Mount G2 system with fewer components is easier to set module tilt angles. The single row, vertical pipe structure offers ground clearance along with the Power Rail module clamping system and lock-in-place RAD twist bolts. The system supports two to four PV solar modules high in landscape orientation and provides unlimited horizontal expansion.

A Skid-Less Utility Inverter
The Power Xpert 1500-KW outdoor-rated, utility-scale inverter allows customers to replace three small inverters with one larger one. With a true megawatt inverter and transformer coupling, the inverter enables a skid-less station. It uses an MV pad-mount transformer, which is connected to the inverter by a direct-coupled throat connection. True reactive power (VAR) support means no power derating up to a ±0.91 power factor range. Fault-tolerance is achieved by a segmented and fault-isolating design.

Inverter For Limited Space
This 30-KW solar inverter delivers 480V AC three-phase power and supports grounded PV arrays without an internal or external transformer. It weighs 94 pounds compared to the 1,200 pounds of conventional 30-KW, 480V AC photovoltaic solar inverters with isolation. The inverter conforms to UL 1741 and achieved a CEC-weighted efficiency of 96.5%. The IPC solar inverter is used for commercial rooftop arrays or PV parking structures, where physical space restrictions can add significantly to installation costs.

Island Inverters With High Efficiencies
The Sunny Island 4548-US and 6048-US off-grid solar inverters reach 96% efficiency and CEC-weighted efficiencies up to 94.5%, as well as up to a 20% increase in power output for the 6048-US. The inverters pair with SMA’s Multicluster Box, making them ideal for 3- through 100-KW off-grid PV systems. Both include intelligent battery management for maximum life, state-of-charge calculation and AC and DC coupling.
Module Warranty Includes Microinverter
The Mage Solar module with frame-attached microinverter features module performance warranties and guarantees but distinguishes itself by extending the 30-year product warranty to the inverter element as well. The 60-cell polycrystalline AC-module is UL-, CEC- and FSEC-listed, plus ARRA-compliant.

Protection For Clear Cold Days
The Classic Lite MPPT Controller, with output up to 96 amps, features HyperVOC to preserve a system in clear cold weather. The controller’s six LED lights indicate its mode, including current limit, ground fault, bulk, absorption, float, equalize and resting. It features 380 days of data-logging, viewable on a PC or by using the optional display panel. Local app software logs up to 12 different selected values, captured every two seconds.

MPPT Without A Fan
The FLEXmax Extreme, a maximum power point tracking (MPPT) charge controller with passively cooled design, offers full power output from -20 to 45°C without a fan in a sealed unit that protects from contaminants. By eliminating the cooling fan, the MPPT removes the greatest obstacle to long service life and high reliability. The system features a ground-agnostic design, increased wire-bending space and oversized terminals.
