Revised on 1 October 2026: The spec sheet footnotes CSA C22.2 #107.1:2015 to model MI-200-2P-HYB-AW-04 only, so it does not apply to this MI-200-2P-HYB-AW-03 record.

PV and storage ports
Three hybrid inverter ports at 120/240 VAC, 90 A maximum each, supporting EG4 12kPV, 18kPV, FlexBOSS18 and FlexBOSS21; plus four smart ports usable for smart loads or AC coupling at 125 A, 80 A, 60 A and 60 A
Official datasheet
Sources

The spec sheet states third-party inverters are not supported and cannot be connected to the hybrid ports, and that a correctly sized breaker must be fitted per inverter (50 A for 12kPV, 70 A for 18kPV and FlexBOSS18, 90 A for FlexBOSS21). There is no direct photovoltaic input: the device interconnects inverters, not arrays.

Maximum grid current. The same 200 A figure is published for the backup and non-backup ports. EG4 states the 200 A service entrance rating applies only when the unit is used with an Eaton CSR2200N (CSR25K) 200 A main breaker, in the United States only.

    Manufacturer specification sheet, version 1.1.8 with a changelog entry dated 17 June 2026, downloaded from the GridBOSS product page on 21 September 2026. It records the ratings EG4 publishes and the standards it lists; the certification lines are the manufacturer’s own statement, not an issuer verification, and the document itself says data are subject to change without notice.
