In modern photovoltaic installations, it is increasingly less common for only the power of the modules and the selection of the inverter to matter. Today, the key factor is how energy is used on-site – meaning self-consumption, system stability and real savings over the year.
That is why solutions such as HEMS (Home Energy Management System) are gaining importance, i.e. home energy management systems. One such device is GoodWe EzManager (EzManager3000) – a solution that acts as the “brain” of the installation and helps control the flow of energy between PV, storage, the grid and loads in the building.
GoodWe EzManager is a HEMS device that collects data from the installation (production, consumption, storage status, grid import) and enables automatic control of system components in such a way that energy is used as efficiently as possible.
In practice, EzManager does not replace the inverter – it complements it. The inverter is responsible for conversion and energy operation, while EzManager supports the control logic: when to charge, when to discharge, when to start loads and how to respond to tariffs.
The biggest value of a HEMS in a home is maximizing self-consumption. EzManager helps use energy on-site instead of exporting it to the grid, which is very important in conditions where the profitability of PV depends on how much energy the user consumes directly.
In installations with energy storage or additional loads (EV, heat pump), manual control quickly becomes inconvenient and ineffective. EzManager makes it possible to set operating scenarios and priorities, so the system works automatically – without daily user supervision.
Depending on the tariff and consumption profile, EzManager can support the system strategy in terms of:
EzManager integrates with the GoodWe SEMS+ platform, which means convenient monitoring and system management in one place – especially important when the installation has more components than just “PV + inverter”.
B2B offer: if you design installations with energy storage or self-consumption-oriented systems, at Gvolt we will help you select compatible GoodWe solutions and control components for a specific site.
The operation of EzManager can be described simply: the device collects data from the system, analyzes it and controls the installation according to defined priorities.
EzManager in practice:
Example operating scenario:
EzManager3000 is designed to integrate various elements of the building energy system, which makes it possible to build a “smart” installation without using many separate controllers.
Example integration possibilities:
From the installer’s point of view, flexibility of installation and integration is important. EzManager3000 offers a wide set of interfaces, making it adaptable to different configurations:
In practice, this facilitates integration with devices in the building and launching scenarios that increase self-consumption and reduce energy costs.
For many projects, mounting and environmental parameters are important. In the case of EzManager3000:
It is a compact device that can be conveniently integrated into a distribution board or technical area.
EzManager will be a particularly good solution if the user:
The PV market is moving towards installations designed for self-consumption and energy control. More and more users are looking for solutions that:
GoodWe EzManager meets these needs – especially in installations where maximum efficiency, control over the system and the ability to expand in the future matter.
GoodWe EzManager (EzManager3000) is a practical solution for PV installations that are meant to operate as a system, not just as an energy source. Combined with an inverter, energy storage and load control, it increases self-consumption, automates system operation and improves control over energy costs.
If you are planning PV installations with energy storage, EV charging or a heat pump – it is worth considering HEMS as an element that realistically increases the value of the entire project.
