ES Uniq - GoodWe hybrid inverters

GoodWe ES Uniq 8–12 kW (GW8000/10K/12K-ES-C10) — hybrid inverters for home solar, backup power and smart energy

The GoodWe ES Uniq 8–12 kW range includes single-phase, low-voltage (48 V) hybrid inverters designed for residential PV systems where self-consumption, reliable backup, generator support and load management matter. The series features two MPPT trackers, supports PV oversizing up to 200%, fast UPS-level transfer < 4 ms, microgrid operation, and parallel connection of up to 6 inverters to scale system power.

Core technologies and benefits

• 2 MPPT + high tracking accuracy (MPPT up to 99.9%) for better harvesting on mixed roof planes/azimuths.

• High efficiency: up to 97.6% max efficiency (96.2% European efficiency).

• Protection and durability: integrated protection functions, built-in AFCI, IP66 enclosure, SPD Type III and more — suitable for demanding residential environments.

• 3-in-1 port (GEN / Smart Loads / inverter in microgrid) — a practical architecture for “grid + PV + battery + generator + priority loads” scenarios.

Integration with Home Assistant and openHAB (OpenHub)

ES Uniq offers interfaces and protocols commonly used in smart-home energy systems: RS485, Wi-Fi/LAN/Bluetooth, plus Modbus RTU and Modbus TCP. This enables telemetry (PV/grid/battery/load), automations and energy monitoring.

• Home Assistant: the GoodWe Inverter integration can be used for local monitoring and energy-flow sensors.

• openHAB: a typical setup uses the Modbus Binding (Modbus TCP and serial RTU), exposing inverter data as Items for rules and scenes.

Automation examples

• “Savings”: enable water heater/floor heating/EV charging when PV exceeds a threshold and battery SOC is sufficient.

• “Backup”: on grid outage, shed non-critical circuits while keeping critical loads (internet, boiler, fridge).

• “Generator”: start/stop a generator based on battery SOC or a timer (when GEN port control is used within an approved wiring/configuration).

Inverter, battery and generator connection should be done by a qualified electrician.

External generator support: what types and what power

ES Uniq accepts a single-phase generator 220/230/240 V with an input voltage range of 170–280 V and 50/60 Hzfrequency (45–55 / 55–65 Hz). In practice, single-phase gasoline or diesel generators with stable voltage/frequency regulation (AVR or inverter-type preferred) are suitable, as long as they match the limits below.

Sizing guidance: use rated apparent power (kVA) aligned with the inverter model and keep headroom for peak loads.

PV side: MPPT, strings and maximum PV power

The 8–12 kW models use two MPPT trackers. Maximum PV power: 16 kW (8 kW model) / 20 kW (10 kW) / 24 kW (12 kW), PV input voltage up to 600 V, MPPT operating range 60–550 V.

Batteries: power, current and compatible options

ES Uniq supports 48 V battery systems (range 40–60 V) and works with Li-ion and lead-acid batteries. Maximum continuous charge/discharge currents: 160 A / 200 A / 240 A (8/10/12 kW). Max charge power: 8 / 10 / 12 kW, discharge up to 8.8 / 11 / 13.2 kW (per datasheet limits).

Examples of compatible LiFePO₄ / lithium batteries (based on GoodWe compatibility lists):

• GoodWe Lynx Home U (LX U), GoodWe Lynx Home A (LX A)

• BYD Battery-Box (LV / LVS / LVL etc.)

• LG RESU LV

• Pylontech (US2000/US3000/Force etc.)

• Dyness, Alpha-ESS, Soluna, Tecloman and others (depending on model/firmware)

Fast installation and scalable power (parallel operation)

For installation, practical parameters matter: wall-mount design, dimensions 560×444.5×226 mm, weight 27–29 kg, IP66 protection. This simplifies mounting in a utility room or on a protected exterior wall.

If demand grows (home + workshop, electric heating, EV charging), the series supports parallel operation of up to 6 inverters, enabling higher power without replacing the entire system.
