Sigenergy Sigen Hybrid 6.0 TP 6kW6kW three-phase battery-ready hybrid inverter

Overview

The Sigen Hybrid 6.0 TP is a first-generation Sigenergy three-phase inverter rated 6kW nominal and 6.6kVA maximum, with two MPP trackers taking up to 9.6kW of PV. It runs as a PV inverter on the wall and, once a battery licence is purchased and activated, can be mounted on a stack of one to six SigenStor BAT modules to work as a hybrid storage system. Its 10-second peak is 9kW. Efficiency is 98.2% maximum and 96.6% European, and Sigenergy recommends a 25A AC switch.

• 5.0–30.0kW, 380/400V, 2–4 MPPT
• PV up to 160% of AC rating, 1,100V input
• Battery function enabled by purchased licence
• Mounts on 1–6 SigenStor BAT modules
• IP66, smart air cooling, 36kg
• CEI 0-21, CEI 0-16 and VDE-AR-N 4105 certified

How it works

The Sigen Hybrid TP is Sigenergy's first-generation three-phase hybrid inverter. Supplied as a wall-mounted PV inverter, it can later run with storage: the owner buys and activates a battery licence, and the installer moves the inverter from the wall onto a stack of SigenStor BAT modules, where it becomes the top unit of a SigenStor system, as described in the SigenStor Home three-phase installation guide.

The datasheet names SigenStor BAT 5.0 and 8.0 modules, one to six per inverter, in the 600–900V range; the current three-phase installation guide also lists BAT 6.0 and 10.0. With a Sigen Gateway the system supplies backup loads and can coordinate a diesel generator, and a Sigen power sensor at the grid connection point enables zero export.

Key features

Ten sizes span 5.0 to 30.0kW. The 5.0–8.0 TP use two MPP trackers, the 10.0–15.0 TP three and the 17.0–30.0 TP four, each taking one string at 16A (20A short-circuit) between 160 and 1,000V. PV can be oversized to 160% of nominal power, and for 10 seconds the inverter supplies 150% of its rating on the sizes up to 20kW. Protection covers insulation and residual current monitoring, type II DC/AC surge arresters and, on certain models, AFCI.

Installation and compatibility

The 700×300×283mm housing weighs 36kg, uses smart air cooling and is rated IP66 for -30 to +60°C and 0–95% humidity up to 4,000m. Sigenergy recommends AC switches rated at least 380V, from 25A for 5.0–8.0kW up to 63A for 30.0kW, and 4–6mm² copper AC, earth and PV cables on the smaller sizes. The 30.0 TP is only available in certain regions.

Certificates in Sigenergy's download centre cover CEI 0-21 and CEI 0-16 for Italy on all sizes from 5.0 to 30.0 TP, plus VDE-AR-N 4105, EN 50549-1, NC RfG, C10/11 and TOR Erzeuger Typ A for 5.0 to 25.0 TP. Supported earthing systems are TN-S, TN-C, TN-C-S, TT and IT.

Monitoring and settings

Communication uses WLAN on 2.4GHz, Fast Ethernet, RS485 or a Sigen CommMod 4G module. Commissioning and monitoring run in the mySigen app; with a battery the owner chooses self-consumption, time-based control, full feed-in, Sigen AI or remote EMS modes and can set a backup reserve and a peak-shaving limit for grid import.
