Sigenergy SigenMicro Inverter 1000W 2-in-1 Microinverter

The Sigenergy SigenMicro 1000 is a 2-in-1 microinverter that connects two independent PV modules to a single unit, each with its own dedicated MPPT channel, delivering a combined 1000W nominal output. It is ideal for rooftop arrays and balcony solar setups where installers want to reduce the number of individual units per string while keeping full module-level independence.
Built on Sigenergys DAB (Dual Active Bridge) topology, the SigenMicro 1000 reaches conversion efficiencies of up to 97.5%. Each of its two inputs tracks its module independently via separate MPPT, so shading or mismatch on one panel does not drag down the output of the other. The unit shares the same WLAN Mesh communication, built-in EMS and AI-assisted commissioning found across the SigenMicro range.
This 2-in-1 unit requires two PV modules, each within a compatible power range of 400W to 670W and an input voltage window of 16-60V. Both module inputs operate on independent MPPT channels, so the two connected panels do not need to be identical, but confirm each modules Vmp and Voc fall within the supported range before ordering.
