GoodWe ET G2 (GW6000-15000-ET-20 AFCI) - 4 reasons why. + Lynx D (HV)

GoodWe ET G2 hybrid three-phase inverters (6-15 kW) are HV-class units that combine high efficiency with safety features and <10 ms UPS backup. The series is designed for flexible installations, supports large oversized DC and HV storage operation.

1) 3 MPPT starting at 10 kW - three slopes without compromise

  • ET G2 has 2/3 MPPT: 2 in 6-8 kW models and 3 MPPT in 10/12/15 kW (1 string per MPPT).
  • MPPT operating range: 120-850 V, 150 V start; UDC,max = 1000 V.
  • Max current per MPPT 16 A,ISC up to 24 A - compatibility with "high-current" modules.

2) UPS <10 ms + full EPS mode.

  • Switching to back-up mode <10 ms - standard in ET G2.
  • Power in back-up mode = model power (e.g. 10 kVA) + 60 s overload (up to 18 kVA for 10K).
  • Parallel operation of up to 4 units (increasing system power).

3) Asymmetric power dissipation

  • Support for unbalanced phase operation (unbalanced output). In 6/8/10 kW models - up to 150% per phase (according to the note).
  • More stable operation under uneven loads and higher grid voltages.

4) Safety + communication

  • SPD type II on DC and AC side, IP66, natural cooling (no fans).
  • AFCI 3.0 (optional feature by card), remote shutdown.
  • Wi-Fi/LAN/Bluetooth to portal, RS485/CAN to BMS, RS485 to meter.

GoodWe Lynx Home D energy storage (HV 5-40 kWh) - full compliance.

GoodWe Lynx D is a high-voltage energy storage based on LFP (LiFePO4) with scalability from 5 kWh to 40 kWh (up to 8 modules in one installation). Each LX D5.0-10 module has 5 kWh of usable energy, 3 kW of continuous power and 5 kW/10 s of peak power. It communicates with the inverter via CAN and has IP66 - suitable for wall or floor (tower) mounting.

Parameter LX D5.0-10 (module) System (1-8 modules)
Usable energy 5.0 kWh* 5-40 kWh (1-8 x 5 kWh)
Voltages Nominal: 435 V (charging), 380 V (disconnecting); 320-480 V range HV range compatible with ET G2 input
Power 3 kW continuous; 5 kW / 10 s (peak) Linearly scalable depending on the number of modules
Communication CAN (BMS ↔ inverter) Auto-detection, remote diagnostics/updates via inverter
Operating temperatures Charging: 0...+53 °C; discharging: -20...+53 °C Humidity 0-95%; altitude up to 4000 m
Degree of protection IP66 Indoor/Outdoor
Dimensions / weight 700×380×170 mm; 52 kg (module) Wall / floor (stack)
Certifications IEC62619, VDE-AR-E 2510-50, CE, UN38.3 EMEA datasheet

Lynx D data source: EMEA datasheet (EN).

ET G2 + Lynx D integration - installation practice:
- ET G2 battery voltage range of 150-720 V fully covers HV Lynx D (320-480 V modular); nominally 500 V on the inverter side.
- Battery control and diagnostics are performed over the CAN bus (BMS). Commissioning: SolarGo application / SEMS portal (auto-detection).
- In EPS/UPS mode <10 ms ET G2 supplies critical circuits from Lynx D with power up to Pn of the inverter (short-term overload according to the table).

Why GVOLT relies on GoodWe.

  • Flexible design: 3 MPPT from 10 kW + high current MPPT (16/24 A).
  • Ruggedness and safety: SPD T2 DC/AC, IP66, AFCI 3.0 (optional).
  • Blackout readiness: UPS <10 ms, back-up mode to rated power.
  • Ecosystem: native compatibility with Lynx D storage and common SEMS monitoring.
