The Deye SUN-12K-SG01HP3-EU-AM2 is a three-phase high-voltage hybrid inverter with a rated AC power of 12 kW, designed for both grid-connected and off-grid applications. The inverter acts as a central power controller within PV systems using high-voltage batteries (HV battery stack ±160-700 VDC) and one or more PV strings.
The inverter is equipped with two independent MPPT trackers, each with one or more parallel inputs.
- MPPT voltage range: typically 150-850 VDC
- Max. DC input voltage: ~1000 VDC
- Max. DC input power: ±15.6 kWp for the 12 kW variant
The wide MPPT range allows serial configurations of 12-18 panels per string (depending on Voc). The internal DC bus is high voltage based, which increases energy conversion efficiency and reduces thermal losses. The PV input features DC reverse-polarity detection, DC inrush current limiting, and electronic surge protection (SPD Type II).
The SUN-12K-SG01HP3-EU-AM2 features an emergency power output (EPS/Backup), fully galvanically isolated from the mains side.
- Switching time: < 20 ms
- Peak power: up to 1.5× rated for several seconds
- Suitable for critical loads
When the grid fails, the backup output is powered locally from PV and/or battery, with autonomous frequency control.
