Protection coordination
Breaker, fuse, SPD and disconnect schedules are checked as one electrical system.
Eaton helps EPCs, developers and facility owners connect Batteries & Energy Storage Systems, BOS protection, Solar Inverters & Microinverters and EV charging assets into disciplined electrical architectures.
| Review Point | Eaton Guidance |
|---|---|
| Battery chemistry and runtime | LFP, UPS backup and commercial BESS duty cycles mapped to load profile and reserve margin. |
| Protection coordination | Breaker, fuse, SPD and isolation points verified against available fault current and site service voltage. |
| Monitoring interface | Gateway, metering and alarm points documented for facility BMS and O&M workflows. |
| Review Point | Eaton Guidance |
|---|---|
| Disconnect placement | AC and DC disconnect locations evaluated for code access, lockout practice and emergency serviceability. |
| Combiner and surge protection | String aggregation, SPD type and enclosure rating aligned to rooftop, ground mount or battery container conditions. |
| Transformer interface | Dry type and pad-mounted transformer scope coordinated with inverter output and utility interconnect requirements. |
| Review Point | Eaton Guidance |
|---|---|
| Inverter topology | Hybrid, string, microinverter and backup inverter selections compared against resilience and expansion targets. |
| Grid event response | Ride-through, transfer logic and protective settings prepared for jurisdictional review. |
| EV charging load | Depot or workplace charging profiles integrated with storage dispatch and service capacity planning. |
Breaker, fuse, SPD and disconnect schedules are checked as one electrical system.
Battery cabinets, UPS backup and inverter interfaces are mapped before site procurement.
