String inverter and solar container

What ICs are available for a string or central solar inverter system?

Discover ST's solutions and ICs for your string or central solar inverter system design, including SiC MOSFETs, IGBTs, power modules, microcontrollers and connectivity solutions.

Are string inverters good for energy storage?

Typically, central inverters have been the standard for commercial and utility-scale energy storage applications. But that is shifting as costs drop and developers, EPCs, owners and operators discover more about the performance benefits of string inverters. The solar PV market embraced string inverters first, but energy storage is gaining momentum.

What is a string inverter?

As their name implies, central inverters centralize the project’s energy through one conduit. String inverters use a distributed architecture, breaking the system down into smaller, multiple inverters and usually more than one DC bus. The concept behind string inverters should be familiar.

What is a modular string inverter?

Flexible system design: Modular string inverters open many doors for system layouts. Inverters can be distributed at the end of array rows, clustered in “virtual central” arrangements, co-located near the point of interconnection, and anything in between. Increased energy harvest: String inverters with multiple MPPTs will produce more power.

Can a solar inverter create a microgrid?

Grid-forming capability. Inverters for solar PV are unidirectional, but string inverters designed for energy storage are bi-directional and some (such as those from LS Energy Solutions) have grid forming ability. This opens up the opportunity to create a microgrid.

Does Solis' skid solution work with a 1500 VDC string inverter?

Solis' Skid Solution supports larger scale projects to simplify implementation and work seamlessly with our 1500 VDC PV string inverters (250-350kW). We reduce complexity by placing all supportive architecture for your large project on a single skid.
