GoodWe solar kit 7.08kWp with 5–10kWh storage – GW6000-ET-20 6kW three-phase hybrid inverter7.08kWp three-phase kit with 6kW GoodWe hybrid inverter and 5 or 10kWh Lynx Home D storage

Overview

A three-phase home kit with 7.08kWp of PV, the GoodWe GW6000-ET-20 hybrid inverter and one or two GoodWe Lynx Home D packs (5 or 10kWh), plus DC and AC protection boxes. The 6kW ET G2 inverter takes up to 9.6kW of PV on two MPPTs, charges the 150–720V battery input at up to 30A and switches its backup port in under 10ms. Each Lynx Home D pack has its own BMS, so storage can later grow to eight packs.

• GoodWe GW6000-ET-20, GW10K-ET-20 or GW20K-ET hybrid inverter
• Lynx Home D LX D5.0-10 packs, 5kWh each, LiFePO4
• Backup port switches over in under 10ms
• IP66 inverter and IP66 battery packs
• DC and AC protection boxes included
• SEMS+ monitoring, SolarGo app for set-up

What's in the kit

• 1 × GoodWe GW6000-ET-20
• null × PV modules, 7.08kWp in total
• null × GoodWe LX D5.0-10 (1 or 2, depending on the storage variant)
• null × DC and AC protection boxes

How the kits work

A GoodWe ET inverter manages the PV field, a Lynx Home D battery and the three-phase grid connection. Solar energy covers the loads first, charges the battery and exports what remains; when the grid fails, the BACK-UP port takes over in less than 10ms. Lynx Home D packs each hold 5kWh and integrate their own BMS and DC/DC stage, so they connect in parallel at 320–480V and the storage grows pack by pack without a central control box.

Inverter options

The GW6000-ET-20 and GW10K-ET-20 belong to the ET G2 generation: battery input 150–720V at up to 30A or 40A, PV oversizing to 160% and natural convection cooling without fans. The GW20K-ET belongs to the 15–30kW ET series, with a 200–800V battery input at 50A, two MPPTs taking 30A and two strings each, and a GM3000 meter in the box. All three are IP66 and can be paralleled up to four units.

Battery rules

GoodWe lists the LX D5.0-10 for the ET G2 and the ET 15–30kW series, each with a minimum firmware. Up to eight packs can be installed, at most four per stack and two stacks, for 40kWh. Each pack supplies 3kW nominal and 5kW for 10 seconds, charges from 0 to 53°C and discharges from -20 to 53°C. A black-start button restarts battery and inverter when there is neither grid nor PV.

Installation and what to add

Packs stand on an optional base or hang on a wall rack; GoodWe recommends the base above three packs and requires a terminating resistor on the last pack. The kits include DC and AC protection boxes. The installer adds mounting structures, string and battery cabling (6 or 10mm² DC cable to the inverter), the earth connection, an RCD where required (for the ET G2 GoodWe recommends type A, 300mA grid side and 30mA backup side) and the grid connection request.
