Overview

Entogo provides the grid-connection equipment that brings solar, storage and hybrid renewable projects onto the network — grid-connection cabinets and boxes, prefabricated PV box-substations, combiner boxes and power conversion — engineered to align with IEEE 1547 and UL 1741 interconnection requirements.

Connecting a renewable project to the grid is its own engineering problem, distinct from generating the energy. Entogo supplies the equipment that sits at the interconnection point — new-energy grid-connection cabinets and boxes, prefabricated photovoltaic box-substations, AC/DC combiner boxes and power conversion — specified to align with the IEEE 1547 and UL 1741 requirements that govern distributed energy resources in North America.

For solar, storage and hybrid projects, the grid-connection package is what turns generation into deliverable power: combiners and conversion aggregate and condition array output, a PV box-substation handles transformation and switching as a factory-tested unit, and grid-connection cabinets manage the interface with the network.

When the grid is the constraint

Interconnection queues and weak feeders increasingly delay projects that are otherwise ready to build. Entogo’s grid-connection equipment is designed to pair with battery storage for firming and grid-forming, and extends to grid-forming off-grid and PV-storage-diesel hybrid configurations — letting a site generate and use power where the connection is weak, delayed or pending, then energise cleanly once interconnection approval arrives.

FAQ

Common questions

What equipment is needed to connect a renewable project to the grid?
A grid connection typically needs combiner boxes and power conversion to aggregate array output, transformation via a PV box-substation, and grid-connection cabinets that interface with the network — all specified against interconnection requirements such as IEEE 1547 and UL 1741.
Can the package include energy storage?
Yes. Grid-connection packages are designed to pair with battery storage for firming, grid-forming and hybrid configurations, including grid-forming off-grid and PV-storage-diesel hybrid systems for sites with weak or delayed grid connection.
What is a PV box-substation?
A prefabricated photovoltaic box-substation integrates the transformation and switching a solar plant needs to connect to the grid into a single factory-built and tested unit, shortening on-site work and energisation time.
How does this support projects stuck in interconnection queues?
Off-grid and hybrid grid-forming configurations let a project generate and use power where the grid connection is weak, delayed or pending, while interconnection-aligned equipment is ready for energisation once approval arrives.
