Old grid connection standards, perhaps influenced by skeptical grid operators, mandated that wind and solar inverters needed to disconnect from the grid if it became unstable. Enter: UL1741, a set of the latest grid connection standards that mandate new inverters stay connected and help out.
Now, UL1741 inverters support the grid by staying connected for longer periods of time after a slight change in voltage. If a voltage or frequency change occurs on the grid, the inverter must ride-through that instability event.
Our inverters are fully UL 1741 SA certified. You can connect them to the grid right out of the box and enable your inverter-based device to remain compliant with the latest certifications, including UL 2035, which includes enhanced performance requirements from inverter-based devices.
Instead of disconnecting, UL1741 mandates that inverters stick around and help, causing renewables to strengthen the grid, instead of weakening it. In addition to demands of power control, the inverter must also support the grid by remaining connected during grid instability events.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
