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.

## 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.
