SigenMicro is Sigenergy’s module-level solar inverter family. Its four-model global schedule is preliminary. SigenMicro 400 and 500 each connect to one PV module, while 800 and 1000 connect to two. Availability is limited to selected regions, and current UK new-supply status remains unconfirmed.
Input and output
All four models use a 16 to 60 V MPPT range. Maximum input current is 16 A per connected module and maximum short-circuit current is 25 A per input. Nominal AC output is 400, 500, 800 or 1,000 W as the model name indicates.
Maximum efficiency is 97.5% and European efficiency is 96.7%. The enclosure is rated IP67.
Branch design and monitoring
SigenMicro uses WLAN and a mesh arrangement between units. It supports PV module-level monitoring.
UK approval and warranty
Before UK installation, the exact SigenMicro model should be checked in the current ENA Connect Direct device database. The former public Type Test Register closed on 16 April 2024. A preliminary datasheet or overseas approval is not a substitute for a current device record.
The European inverter warranty lists SigenMicro 400, 500, 800 and 1000 for 15 years.
