Critical Power & Interconnection Requirements
- Voltage profile: [NEEDS VERIFICATION] - no AC voltage, DC battery voltage, or MPPT window data was provided for this accessory kit.
- Continuous / surge ratings: [NEEDS VERIFICATION] - not specified in manufacturer data.
- This kit does NOT include an inverter, charger, or monitoring electronics — it is breaker hardware only.
- This kit does NOT include the GridBOSS unit itself.
Breaker sizing mismatches are a common source of nuisance trips or, worse, undersized conductor protection when adding distribution accessories to an existing GridBOSS install. Before landing any breaker from this kit, verify the amperage rating against your as-built load calculation and the GridBOSS unit's rated output — a mismatch here can trip fault codes on the monitoring node or fail an inspector's panel schedule review. Confirm torque on every lug with a calibrated torque wrench to the manufacturer's spec; under-torqued lugs are a leading cause of high-resistance heat faults in distribution gear. Document your breaker kit installation against NEC Article 705 (interconnected electric power production sources) if this kit ties into a service panel, and keep the panel schedule updated for your utility's interconnection review.
