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.

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 SolarEdge Home Hub inverter’s industry leading 99% weighted efficiency paired with its ability to DC oversize up to 200% allows installers to install more power, increase system ROI, and better meet the increasing energy needs of their customers. Additionally, the DC-coupled Home battery offers installers the ability to install the inverter, battery, and EV charger on a single breaker which enables faster installation both at the time of install, as well as with future additions, with fewer main panel upgrades. DC coupling allows for inverter, battery, and EV charger to be installed on one breaker, resulting in fewer main panel upgrades, and lower installation costs. All of this paired with a standard warranty of 12 years extendable to 25 years, integrated arc fault protection, and in app features such as Weather Guard, enables installers to offer their customers increased peace of mind and reliability.

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.
