Guided renewable energy equipment specification from first diagram to approved submittal.

Eaton service support is designed for teams that already know the project must work electrically, commercially and operationally. Our role is to turn early load assumptions, interconnection limits and equipment preferences into a defensible scope for Batteries & Energy Storage Systems, BOS Components, Solar Inverters & Microinverters and EV Chargers.

Engineers reviewing renewable energy diagrams

Storage and backup architecture

We review runtime, load shedding, UPS behavior, battery cabinet placement, thermal assumptions and metering points. The output is a practical equipment path that explains what must be coordinated before purchase orders are issued.

BOS protection coordination

Disconnects, surge protection, combiner boxes, busbars and transformers are examined as a system. This reduces the common problem of selecting correct individual devices that still leave gaps in service access or fault coordination.

Conversion equipment review

Hybrid inverter, string inverter, microinverter and power inverter requirements are compared against site voltage, grounding method, grid response expectations and monitoring needs.

EV charging integration

Charging infrastructure is connected to service capacity, storage dispatch, demand management and future expansion so depot or workplace loads do not become an isolated design afterthought.

Decision support

Questions answered before the bill of materials hardens.

The first pass checks the single-line diagram, site voltage, critical load list, environmental conditions and target renewable operating mode. Eaton then identifies missing assumptions, product families that belong in scope, and documentation that should be prepared for AHJ, utility or owner review.

Yes. Early reviews are often most useful before model numbers are locked. The service can define capacity bands, protection intent, enclosure constraints, monitoring points and the decision data needed to move from concept to exact equipment.

Before review

  • Separate lists for batteries, inverters and BOS devices
  • Unclear protection coordination across AC and DC boundaries
  • Limited documentation for utility or owner questions
  • Late discovery of service access and enclosure constraints

After review

  • Equipment scope tied to operating duty and voltage class
  • Defined disconnect, SPD and transformer coordination path
  • Submittal notes prepared with project assumptions visible
  • Maintenance and monitoring needs considered before install

The guided service is intentionally methodical. It does not replace the engineer of record, local code review or utility approval, but it gives those parties a cleaner starting point. For renewable projects with storage, inverter conversion and charging loads, that clarity can prevent repeated redesign, mismatched device ratings and ambiguous owner expectations. Eaton keeps the conversation anchored in practical electrical evidence: available fault current, load duration, voltage class, installation environment, communication requirements, transfer behavior and long-term service access.

Submit project data for a structured review.

Attach the single-line, load profile and project timeline so the response can focus on the decisions that matter.
