NEP's Rapid Shutdown units are 20Amp models. The PVG-2 (dual PV) and PVG-3 (3 PV modules) are built with a metal enclosure. Why metal? The industry has seen numerous examples of RSD reliability issues with Non-NEP units. To reduce the risk of such, a metal enclosure improves heat dissipation and overall thermal management. Also, a metal enclosure is more robust, ‘fail-safe’ engineering investment to lower overall risk and improve the expected life-span of the devices. These same units are tested to 25Amp in Europe (CE marking). Lots of design margin with this improvement.

The Sunny Highpower PEAK3 FLEX US-21 (PEAK3 FLEX) model delivers adjustable AC outputs for power, current and voltage. The PEAK3 FLEX can be tuned to match older inverters that might operate at now uncommon voltages, like 385VAC or 400VAC, thus enabling customers to leave the transformers in place and avoid costly or time-consuming studies.  Similarly, the AC output current can be adjusted to help customers avoid replacing AC wires and OCPD equipment.

Adjusting the AC Voltage downward also widens the DC operating window of this 1500VDC inverter, so the PEAK3 FLEX can repower older projects with central or string inverters that were built at 600VDC or 1000VDC. Once field commissioned to the desired AC output values, the UL label will be completed to match, and those parameter settings are lockable behind OEM password protection.  The flexibility in design, capacity and capability makes the Sunny Highpower PEAK3 FLEX the perfect inverter solution for repowering projects.

Solis’ fuse-free design supports long-term reliability, further enhancing the overall return on investment for large systems.Not many products this size have the wide array of voltage options and already integrated AFCI, making this a great , versatile solution for large-scale projects.

Size / category: Residential and Commercial Inverter Wi-Fi / Cellular Data Logging Device

The best “combination” Wi-Fi / Cellular data logging communication device on the market.  NEMA 3R, plug-and-play connection to the Solis inverter external comm port.  Powers up and begins broadcasting with 2 minutes.  Default Wi-Fi to the local router.  However, if the router fails, within 2 minutes, the W4G “stick” finds the nearest GSM or LTE cellular tower.  No breaks in data, ever.  Physical reset button and three (3) LEDs on the front tell the installer what the device is doing.  The Solis Wi-Fi / Cellular “stick” is a data logging communication tool that can broadcast data from as many as ten (10) Solis residential or commercial PV string inverters daisy-chained with Solis cords or CAT5e cable.  The S1-W4G-ST is also a great troubleshooting tool.  Using the S1-W4G-ST, an installer can connect any Solis inverter to the nearest cell phone tower and see if the inverter is broadcasting data to the Cloud.

• Touch-safe, plug-and-play installation with no configuration of the device
• Easy Wi-Fi connection to the local router using the installer’s own cell phone
• NEMA 4X, installed under the inverter for all-weather performance
• Each Solis data logging device can broadcast data from as many as 10 inverters
• Small, rugged and easy to carry, the Solis Wi-Fi / Cellular data logging device can be a handy trouble-shooting tool

The new SolarEdge TerraMax 330kW Inverter is designed to maximize energy production for any project terrain and for overcoming challenges posed by shading and uneven terrain on community solar ground mount sites. In addition, it is the ideal product for agri-PV, small-medium utility-scale projects and floating PV. It delivers more energy with 200% DC oversizing for up to 50% less Balance of System (BoS) costs (Based on comparisons using HelioScope on 8MW projects and typical string inverters. Numbers can change based on project characteristics).

In terms of power, this inverter helps ensure continual peak performance with an integrated PID (Potential Induced Degradation) rectifier and boosts energy yield through DC-optimized technology with multiple MPPTs.

To save on BoS costs, the inverter works with fewer and longer strings on up to 80 modules, and further streamlines by providing higher power through fewer units. The SolarEdge TerraMax inverter also speeds up onsite work with a topology feature that places the inverter in a central location alongside distributed, multiple MPPTs in the array. These factors can reduce labor, installation time and material cost with virtual central topology and single DC input architecture.

Finally, the TerraMax Inverter also simplifies operations & maintenance, reducing unnecessary truck rolls with granular, module-level monitoring, and reducing schedule risks and maximizing system uptime with automatic alerts and remote troubleshooting capabilities.

Key specs:

• kW range: 330kW
• Operating voltage range: 587-759 Vac
• of MPPTs / MPPT voltage range: 12.5-105 Vdc
• Max / CEC efficiency: 2/99.0%

Supporting high power 650W modules, SolarEdge H1300 Power Optimizers enable modules in the array to work independently. The underperformance of one module will not affect others in the string, eliminating mismatch-related power losses due to shading, soiling, or aging, enabling higher overall energy production. 

The H1300 also helps to harvest more energy from bifacial modules by mitigating electrical losses caused by the varying ground albedo, shading, obstructions, or other rear-side factors. Further, inter-row shading losses are minimized with module level MPPT. Plus, up to 80-module string length is supported, resulting in fewer strings and enabling up to 50% BoS savings when compared to traditional string solutions.

Additionally, the H1300 helps keep production rolling with granular and continuous module-level data monitoring for EPCs and O&M personnel. It tracks system performance and helps to pinpoint & resolve issues remote or onsite using our Monitoring Platform.

The hybrid architecture of the EI Inverter delivers a wider operating voltage range, enabling energy production earlier in the morning and later into the evening. The EI Batteries are charged directly by DC (direct current) electricity and take advantage of the inverter’s 2:1 DC oversizing ratio to charge the batteries with additional power that would otherwise be lost. For grid-tied systems, the Tigo ATS senses grid loss and automatically switches between grid-tied solar, islanding with solar-plus-storage, or battery-only, as needed. With Tigo Flex MLPE devices, installations benefit from module-level monitoring and advanced rapid shutdown safety measures to protect solar professionals, building maintenance personnel, and first responders. Tigo is committed to serving its installers by providing in-depth training and support resources for system design, installation, and monitoring.
