BESS On-grid
The easy to use solution for BESS On-grid energy management
When you need to control the charging, discharging and overall operation of the BESS - the ECpvX is an excellent solution
While parallel to the grid, the controller can control the active/reactive power export. It can be used for:
- Zero Export/Self Consumption to only produce energy behind the meter.
- Scheduled arbitrage allowing the customer to set timers for charging and discharging at feasible time slots.
- Automatic arbitrage based on spot prices from ENTSO-E.
- Grid support, either P/f or U/q based on customizable deadbands (LFSM-O/LFSM-U)
BESS On-grid can be applied in applications that has:
- DC-coupled solar
- AC-coupled solar
- Both DC- and AC-coupled solar.
- Ancillary services (ECgrid)
- Sites with EV chargers
In a DC-coupled system, the DC output from the solar panels is directly connected to the DC input of the BESS, while integration of AC-coupled solar is possible via Modbus RTU or Modbus TCP protocols.
While connected parallel to the grid, the controller has capability to manage the export of active and reactive power. By integrating market price data, it can schedule the charging and discharging of the battery to optimize revenue generation. Additionally, it features a daily charge scheduler for manual timing of operations. The controller prioritizes solar PV to meet the load demand. If load exceeds the solar PV output, the controller utilizes the battery to cover the additional load. If the battery State of Charge (SOC) is insufficent, the remaining load is supplied from the grid.
In cases where the solar PV output exceeds the load demand, the excess solar PV is used to charge the batteries. Once the batteries reach their maximum SOC, any surplus PV is either exported to the grid or set to zero export.
A single line example can be found here for an ECpvX application:
All set up and onsite monitoring are done using our easy-to-use ECweb software.
The site data is freely accessible to read out via Modbus from your ECpvX. The ECpv Modbus data will always be uniform for every site, no matter which brand and model of solar inverter and power meters you are using in the application.
When the ECpvX is connected to the internet, it can produce consumption and production reports with values in terms of kilowatts, penetration, fuel-saving, charging/discharging, PV curtailments and performance ratio - but also report on financial performances.
In addition to live monitoring via ECweb and sharing live data via Modbus. The ECpvX also logs plant data on SD card or USB - enabling a lifetime of logging directly in the unit, which you can utilize for your own analysis. Moreover, all data the ECpvX reads - it can export to our ECcloud, FTP or MySQL databases, you can read much more about data acquisition and monitoring on our monitoring page. Remote service access is possible through our EClink service
ECpvX S, M and L covers any size of solar plant and can easily interface to any genset controller, power meter, Battery Energy Storage System and solar inverter. Check out the full list of supported models on the ECpvX product page
