| Anti-corrosion Class | C4M |
| Dimensions / Weight / Noise | 318 x 226 x 37.5 mm; <=5.1 kg; <=20 dB |
| Footnote *1 on 'Max. Input Voltage (V)' | When the input voltage exceed 65V, the inverter will enter the standby mode, and the voltage returns to 63V to enter the normal operation state |
| Footnote *3 on 'Max. Short Circuit Current per MPPT (A)' | The Brazilian version is 20/20/20/20A |
| IoT compatibility list V17, row 'MIA1.6K/1.8K/2k' | Status 'Mass Production'; ARM Platform ESP32; Communication Module: WIFI BOX (*1 ARM 01 or above); Smart Meter: CT90 (*1); Data Logger: Ezlogger3000R (*1 ARM 01 or above) |
| Max. Efficiency / European Efficiency / MPPT Efficiency | 96.0% / 95.0% / 99.8% |
| Max. Input Current per MPPT (A) | 20/20/20/20 |
| Max. Short Circuit Current per MPPT (A) | 26/26/26/26 |
| Max. Units Per 6mm2 Branch*4 | 4 |
| Nominal Input Voltage (V) | 42 |
| PV String Current Monitoring | Integrated |
| Rapid Shutdown | Integrated |
| Units per AC branch | 3 units with 4mm2 cable; 4 units with 6mm2 cable |
| en.goodwe.com MIS G2 product page marketing copy | 12V ultra-low startup voltage; full power output up to 50 degC; less than 20dB; Wi-Fi Mesh connecting up to 25 units; IP67 & C4M-certified protection; 15-year standard warranty |
| identity.region_as_printed | EU / global EN |
| withheld:topology.max_units_per_ac_branch_detail | "Datasheet publishes two branch limits by cable cross-section: 3 units per 4 mm2 branch and 4 units per 6 mm2 branch (this record carries the conservative 4 mm2 figure). Footnote *4: 'Limits may vary. Refer to local requirements to define the number of microinverters per branch in your area.'" |
| withheld:topology.mppt_independence_detail | "Datasheet prints 'Number of MPP Trackers 4' and 'Number of Strings per MPPT 1' - four trackers, one string each, so every physical PV input has its own MPPT." |
