for applications incorporating battery storage systems
(BESS) alongside various energy sources.
Why choose ePowerControl ES?
Optimize your battery charging strategy
Integrate BESS with various sources like PV, gensets, and the grid. The controller optimizes charging to boost PV use, extend battery life, and cut diesel expenses.
Cross-compatibility with any BESS brands
Integration of multiple and heterogeneous equipment of different brands depending on the type of power plant.
Prioritize battery various uses
Easily select one or multiple features and prioritize them according to your battery charging strategy
Reclaim control of your plant operations
Ensure compliance with local regulation while maximizing solar penetration.
Our range of controller solutions are adapted your needs, including the Hybrid Fuel Saver Controller, ideal for larger installations with multiple gensets.
How does our energy storage controller work?
Features designed to achieve energy autonomy
Time of use management
Charge the storage system with PV production and/or off-peak prices and discharge during peak prices to maximize the value of your onsite production and reduce your utility costs.
Peak Shaving / Time Of Use management
Avoid penalties by reducing load when demand is above the maximum power purchase value.
Export and Import control for a single or multiple Points of Injection
Management of solar inverters, BESS, genset controllers and breakers to limit export to the grid and import (peak shaving) from the grid in grid-tied configuration.
Reactive power management
Reactive power is controlled dynamically to regulate PF at PCC or genset level within a configured range. Includes the possibility to prioritize active or reactive power objectives.
Respects the constraints of your equipments
Configure the active and reactive power ramps, the minimum and maximum SOC, the minimum loading, the rate of setpoints and more to make sure your operations are fully compliant with the constraints of your equipments.
Advanced maintenance and failsafe modes
Maintenance mode for assets to keep logging
data from assets which should temporarily not
be used for control. Optimized failsafes to stop
devices when communication of key elements
are missing.
Monitor your assets with data intelligence
Reliable datalogging & data acquisition
From all linked devices on site (meters, solar inverters, genset controllers, weather stations (irradiance/t°), and I/O modules), & offer a secure local storage.
Data export & visualization
- Locally, over USB,
- Locally, over Modbus gateway
- Remotely, using ePowerMonitor or compatible third-party monitoring platforms (FTP push, API integration).

Frequently asked questions
What are the applications for which the ES series are suited?
ePowerControl ES is another alternative for PV/GRID/BESS & PV/GRID/BESS/DG installations (limited to 300kWp). It offers high quality controllers dedicated to simple standard solar plants integrated with a BESS. Please refer to the ES product page for more details.
Can ES ensure the seamless transition between grid and battery during a shutdown?
Our standard controllers do not manage seamless transition directly, but can be used in coordination with various systems controlling it such as UPS and ATS.
Does the solution support BESS dispatch between batteries of different brands?
In case of multiple batteries of different brands, ePowerControl ES dispatchs the total BESS active power setpoints to the different BESS configured in eConf, our solar controller configuration interface. The produced dispatch ensures that no BESS exceeds the SoC configured range or the active power target range.
Is secondary Islanding Mode (N+2 Reliability) supported?
In case of multiple batteries of different brands, ePowerControl ES dispatchs the total BESS active power setpoints to the different BESS configured in the ePowerControl configuration interface. The produced dispatch ensures that no BESS exceeds the SoC configured range or the active power target range.
