Sigen PV Max is Sigenergy’s grid-connected solar string-inverter family, also named Sigen PV Inverter Max. It is distinct from the Sigen Hybrid Inverter and SigenStor Energy Controller because PV Max has no direct Sigen Battery connection.
Single-phase and three-phase schedules
The current European warranty covers 3 to 6 kW SP models and 5 to 25 kW TP models. SP and TP identify the single-phase and three-phase schedules; the complete code keeps that distinction visible.
The TP schedule has two to four MPPTs depending on rating, with one string and 16 A maximum input current per tracker. Its MPPT range is 160 to 1,000 V and maximum efficiency reaches 98.3%. These are TP-family boundaries, not specifications for the separate SP schedule.
PV-only boundary
PV Max is a PV-only inverter without the Sigen Battery connection assigned to the Hybrid family. A separately AC-coupled battery at the same premises does not change the PV Max product into a hybrid inverter.
UK approval and warranty
UK approval is code-specific and recorded through ENA Connect Direct. The former public Type Test Register closed on 16 April 2024 and is now an archive.
The European inverter-system warranty available on 22 July 2026 gives the named PV Max models ten years.
