SolarEdge hits 1 million monitored PV systems (doubling its total in two years)


SolarEdge has been tracking the importance that monitoring has in the PV industry. This trend is demonstrated by the fact that less than two years ago SolarEdge reached 500,000 monitored PV systems in its system after seven years of sales and now in only two years this figure has doubled – now reaching 1,000,000 million monitored sites.

“Just under a decade ago, monitoring PV systems was a passive and reactive process. System owners would install an expensive PV system without monitoring their investment to ensure maximum performance,” stated Lior Handelsman, SolarEdge’s VP of Marketing and Product Strategy. “But as the PV industry evolves, the role of PV asset management is now seen as being strategically important for the PV system lifetime RoI.”

SolarEdge is celebrating the impact of these 1 million monitored PV sites by focusing on the sites’ positive climate impact. The 1,000,000 monitored PV sites have produced 14TWh of energy, reduced CO2 emissions by nearly 6.5 billion tonnes, which is equal to the equivalent of over 20,000,000 trees planted. More fun facts about the collective impact that installers and system owners make will be presented on SolarEdge’s social media accounts – following along: Facebook, Twitter, LinkedIn, and Instagram.

The 2019 Solar Inverter Buyer’s Guide!

SolarEdge’s free for 25 years monitoring platform, with module-level monitoring and remote troubleshooting, offers real-time insight into system performance from anywhere, and provides value to installers and system owners alike. System owners can track their energy production and monitor both system performance and environmental impact. For commercial systems, the monitoring platform offers a way to track and ensure performance ratio. Installers and O&M providers are able to optimize their business while simultaneously offering tailored PV asset management services.

Dynapower debuts its next-gen utility-scale energy storage inverters


Dynapower just introduced its next generation utility-scale energy storage inverters. The air-cooled CPS-1500 and CPS-3000 are available in both indoor and outdoor configurations, and work with all battery chemistries.

Each feature a high-efficiency, three-level topology designed for both grid-tied and microgrid applications. The Gen 4 CPS inverters also feature Dynapower’s proprietary Dynamic Transfer technology, which allows for the seamless transfer from grid-tied to microgrid mode, and industry-leading Black Start capabilities. Multiple CPS units can be paralleled together to meet the sizing and power needs of any energy storage installation.

Dynapower’s CPS inverters are an integrated solution containing all required protective features, as well as an AC output breaker, and DC disconnect switch. This creates cost savings for end users and integrators when compared with other inverters that require additional add-on items needed for battery integration. CPS inverters can be supplied with MV transformers to easily integrate customer supplied battery systems into any network.

Key technologies

  • BLACK START — In the event of a complete system power outage, Dynapower’s patented Black Start restores power to the facility without the need for external power. Dynapower’s Black Start technology can start distribution networks even with transformer magnetizing currents that exceed the power rating of the inverters. Multiple CPS units can be restarted at once.
  • E COMP— A Volt Var function that provides immediate and automatic voltage support to the grid.
  • F COMP— A Hz-Watt function that provides immediate and automatic frequency support to the grid.
  • DYNAMIC TRANSFER — Dynapower’s proprietary patented Dynamic Transfer algorithm monitors grid stability and, upon detecting a grid disturbance, disconnects from the grid and transitions to stand-alone battery backup power mode on the load connection. The transition is seamless to the critical loads and supports 100% phase imbalance in UF mode.

Morningstar’s Energy Storage Partner Program keeps growing, now includes specs for 12 battery providers

Morningstar Multiwave

At one of the solar industry’s most respected events — the North American Board of Certified Energy Practitioners education conference — Morningstar Corp. announced that its Energy Storage Partner Program (ESP) has more than doubled in size since being introduced just last September.

Morningstar launched the ESP program to make it easier for solar professionals to specify lithium batteries into new systems or drop them into and upgrade existing ones. Initially including five leading advanced battery brands – Discover Battery, NEC Energy Solutions, PowerPlus Energy Solutions, RELiON, and SimpliPhi Power -ESP eliminated the uncertainty and “lithium anxiety” for installers by doing their homework in advance.

How Morningstar designed its software-first solar inverter for the lithium battery age

All critical settings required for switching a system’s electronic control over to lithium-iron phosphate (LiFePO4) chemistry were determined in advance, between Morningstar and the battery brand partner. Installers no longer needed to “ping pong” between a battery manufacturer and a solar system component manufacturer to get the information they needed – ESP provides it up-front in verified documentation. All the installer has to do is access the documentation free of charge, saving them considerable design and set-up time.

Based on its initial success, the next wave of battery partners has joined Morningstar’s ESP program. They include: Trojan Battery, Pylon Technologies, Dragonfly Energy, KiloVault, Blue Planet Energy, Battle Born Batteries, and Lithium Werkes BV.

Information on the program and all its partners is available here.
