Sigenergy 99.9kW 3 Phase C&I PV Solar Inverter 4 MPPT IP66

The Sigenergy 99.9kW C&I PV Solar Inverter (Sigen PV 99.9M1 AU) is a powerful, high-efficiency inverter designed for large commercial and industrial solar installations. Built to support high-capacity solar arrays, this advanced three-phase inverter combines exceptional energy conversion efficiency, extensive safety features, and flexible system design in a durable, compact form factor.
With an impressive maximum PV input power of 199.8kW and eight independent MPPTs (Maximum Power Point Trackers), each supporting two strings, the inverter allows highly flexible string configurations. This makes it ideal for complex commercial rooftop systems or ground-mounted solar projects where panels may be installed across multiple orientations or subject to varying shading conditions. The 98.6% peak efficiency ensures optimal energy conversion and maximum solar generation.
Designed for reliability in demanding environments, the IP66-rated enclosure enables safe outdoor installation while protecting internal components from dust and water ingress. Integrated Arc Fault Circuit Interruption (AFCI), residual current protection, and DC/AC surge protection provide advanced system safety and help safeguard both the inverter and connected equipment.
The inverter also features an intelligent air-cooling system to maintain stable operating temperatures and ensure long-term performance in Australia’s harsh climate conditions. High current input capability of up to 32A per MPPT allows compatibility with modern high-power solar modules, further enhancing system performance and flexibility.
For installers and system designers, the Sigen PV 99.9M1 AU simplifies planning and deployment. The inverter shares the same physical dimensions and weight as other models in the Sigen PV series, making logistics, mounting, and system expansion easier across projects. Parallel operation is supported without the need for an external data logger, helping reduce balance-of-system (BOS) costs.
