EMS PRO 1000
The Solax EMS PRO 1000 is the energy management system (EMS) designed for commercial and industrial photovoltaic systems, as well as solar farms. It manages up to 120 inverters with a master-slave architecture (up to 10 slaves), RS485, Ethernet, and 4G communication, integrated web interface, and remote monitoring via SolaX Cloud. Ideal for optimizing energy flows, export control, and large-scale intelligent maintenance.
The Solax EMS PRO 1000 is the intelligent central controller for energy management in commercial and industrial (C&I) photovoltaic systems and solar power plants. Designed to efficiently coordinate complex systems with dozens of inverters, batteries, and priority loads, it ensures maximum energy yield and full real-time supervision from anywhere.
What is the EMS PRO 1000 used for in a photovoltaic system?
In a system with multiple inverters and storage systems, without an EMS each device operates autonomously and often suboptimally. The EMS PRO 1000 acts as the central brain: it collects data from all connected inverters, optimizes energy flows (self-consumption, battery charging, export management), logs secondary-level faults, and enables predictive maintenance. It supports local monitoring via integrated web interface and remote monitoring via SolaX Cloud, with local data backup for up to 1 year.

When is the EMS PRO 1000 needed?
The EMS PRO 1000 is the standard solution for commercial and industrial photovoltaic systems that require centralized management of multiple Solax inverters. It is necessary whenever you want to: optimize self-consumption across multiple load points, limit grid export at the system level, collect aggregated data for energy reporting, or centrally manage the maintenance of an inverter fleet. It supports systems from small C&I installations up to large ground-mounted solar power plants.

Frequently Asked Questions
How many inverters can the EMS PRO 1000 manage?
The EMS PRO 1000 in master configuration can manage up to 120 Solax inverters. Thanks to the master-slave architecture, it is possible to connect up to 10 EMS PRO slave units to the master, further expanding the supervision capacity for large plants or complex photovoltaic parks.
Does the EMS PRO 1000 work without an internet connection?
Yes. The EMS PRO 1000 has a local web interface accessible via LAN/Ethernet even without an internet connection. Data is stored locally for up to 1 year and, when the connection is restored, it is automatically synchronized with SolaX Cloud without data loss (offline data transmission resumption).
What is the difference between EMS PRO 1000 and standard EMS1000?
The EMS PRO 1000 is the advanced version of the EMS1000, specifically designed for large-scale C&I systems and solar power plants. Compared to the standard EMS1000, it offers support for multi-slave architecture (up to 10 EMS slaves), management of a larger number of inverters, integrated 4G connectivity, and advanced O&M functions such as cell-level battery monitoring and second-level fault logging.
Does the EMS PRO 1000 support system-wide export control (zero feed-in)?
Yes. Among the main functions of the EMS PRO 1000 is parallel energy control, which allows export limitation to the grid by simultaneously coordinating all connected inverters. This is essential for C&I systems subject to export constraints agreed with the utility or for optimal management in shared self-consumption scenarios.
How does the EMS PRO 1000 detect connected inverters?
The EMS PRO 1000 features automatic device detection: at first startup, it automatically detects and assigns addresses to connected Solax inverters via RS485, without the need for manual configuration for each device. Likewise, it automatically detects connected EMS PRO slave units, drastically simplifying the commissioning of complex systems.
