GoodWe EzManager3000 HEMS Gateway
SG-Ready heat pump in the same schedule: One heat pump, connected via DO.
Tariff-aware scheduling: Dynamic and negative tariffs with AI-optimised scheduling.
Retrofit-friendly: on-grid plus storage inverter parallel operation is supported for retrofits.
Compact IP20 gateway: 99 × 85.6 × 71 mm, 0.2 kg, up to 7 W.
Clear device limits per gateway
One hybrid inverter, one grid-tied inverter, two EV chargers, one SG-Ready heat pump and twelve Shelly devices are the listed maxima. Mixed grid-tied and storage setups depend on the inverter model, and data from third-party grid-tied inverters cannot be collected.
Connections for the whole house
RS485 COM × 4 links meters and grid-tied inverters with Modbus-RTU; LAN runs Modbus-TCP. Wi-Fi 802.11 b/g/n, Bluetooth 5.2, DI × 4, DO × 2, CAN × 1 and AI × 1 cover the rest; the heat pump connects via DO.
IP20 gateway for wall, DIN rail or tabletop
The 99 × 85.6 × 71 mm housing weighs 0.2 kg, is rated IP20 and draws up to 7 W. Power comes from a 12 V / 1.5 A adapter with 100 ~ 240 V AC input.
Dynamic tariffs and trading-platform connection
The gateway offers automatic connection to electricity trading platforms, dynamic and negative tariff support, and AI forecasting of generation and use. Station-level modes include AI Mode, Self-consumption and On-Grid Power Control.

Project fit
Where this model fits.
Scenarios that show which projects the GoodWe EzManager3000 HEMS Gateway belongs in, and the limits behind our engineers' recommendation.
Homes with a heat pump, EV charging and storage
A home with a GoodWe hybrid system, an SG-Ready heat pump and EV chargers should run on one energy schedule, including dynamic tariffs.
EzManager3000 schedules the home's energy centrally; the connected devices are monitored and controlled in SEMS+. It takes one hybrid and one grid-tied inverter, two EV chargers, one SG-Ready heat pump and twelve Shelly devices.
- Inverters: up to 1 hybrid and 1 grid-tied; the mixed setup depends on the inverter model
- Heat pump: one, SG-Ready, connected via DO
- Smart devices over Wi-Fi or LAN: up to 12; LAN is recommended for stable communication
- Power: in a hybrid grid-tied setup the gateway is not supplied from the inverter backup side.

Product questions
Will one EzManager3000 cover this inverter and device mix?
One EzManager3000 manages up to 4 hybrid inverters, up to 4 grid-tied inverters, up to 2 EV chargers, 1 heat pump (SG-Ready) and up to 12 Shelly devices. Compare your planned device mix against these figures.
Does the gateway work with dynamic tariffs and trading platforms?
The datasheet states auto-connect to electricity trading platforms, dynamic and negative tariff support, AI-optimized scheduling for maximum tariff savings, and AI forecasting for personalized, habit-based energy optimization. In the tariff setting you select export energy tariff or import energy tariff and set the tariff type, supporting fixed tariff, time-of-use tariff and dynamic pricing. Dynamic pricing obtains dynamic pricing from the utility company and combines it with user-set tariff surcharges to adjust the actual electricity buying and selling tariffs; it is applicable only to certain regions and certain equipment. The manual notes that only some European countries or regions support the use of electricity market tariff, and the current electricity market only supports Nord Pool.
How do the inverters, meters and heat pump connect?
Smart meters and grid-tied inverters connect via RS485. The SG Ready heat pump connects via DO, supporting a maximum of 1 heat pump. Energy storage inverters, AC charger, smart sockets and GoodHeat connect to the router via WiFi/LAN, and the gateway connects to the router via WiFi/LAN; up to 12 smart devices are supported, and LAN is recommended for communication stability. The wiring diagram shows the smart meter on RS485, the SG Ready heat pump on DO, and the grid-tied inverter on RS485. To set the heat pump working mode, select the desired working mode via the SEMS+ App after completing the wiring.
