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 Sigenergy's 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.

Fast Commissioning
AI layout recognition maps each microinverter's position within the array automatically, enabling 5-minute commissioning per installation via the mySigen app, with no manual unit-by-unit address entry required.
System Compatibility
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 module's Vmp and Voc fall within the supported range before ordering.
Dual Independent MPPT
Two separate MPPT input channels allow each connected module to be tracked and optimised independently, minimising losses from shading or mismatch.
DAB Topology
High-frequency, galvanically isolated Dual Active Bridge design delivers up to 97.5% peak efficiency across both inputs.
WLAN Mesh Networking
The world's first WLAN Mesh system for microinverters improves reliability and scales cleanly as arrays expand.
Built-In EMS
An embedded Energy Management System removes the need for a separate network gateway, simplifying installation.
Whitelisting Security
Device whitelisting security gives enhanced protection to the communication network against unauthorised access.
Module-Level Monitoring
Per-panel performance monitoring, ground fault detection and rapid shutdown support give full visibility of both connected modules.
How many solar panels does this microinverter support?
This is the 2-in-1 model, connecting two independent PV modules to a single unit, each with its own dedicated MPPT input, for a combined nominal output of 1000W.
Do both connected panels need to be identical?
No. Because each input has independent MPPT tracking, the two modules can differ slightly in orientation or output without one dragging down the other's performance.
What efficiency can I expect from the SigenMicro 1000?
The unit reaches a peak efficiency of 97.5% and a weighted efficiency of 97.0%, using the same high-frequency DAB topology as the rest of the SigenMicro range.
Does this microinverter need a separate communication gateway?
No. A built-in EMS and WLAN Mesh communication system are integrated into the unit, removing the need for additional gateway hardware.
Is the SigenMicro 1000 suitable for outdoor and balcony installations?
Yes. It carries an IP67 ingress protection rating and operates across -40°C to 65°C, suiting both rooftop and exposed balcony solar installations.
