How does our energy storage controller work?

Features designed to achieve energy autonomy

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.
Avoid penalties by reducing load when demand is above the maximum power purchase value.

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 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.

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.

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

From all linked devices on site (meters, solar inverters, genset controllers, weather stations (irradiance/t°), and I/O modules), & offer a secure local storage.
  • Locally, over USB,
  • Locally, over Modbus gateway
  • Remotely, using ePowerMonitor or compatible third-party monitoring platforms (FTP push, API integration).

Frequently asked questions

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.
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.

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.

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.
