GVOLT - Installer's Guide
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.

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.
