Marshall Technology
Marshall is a smart device connected to a digital platform that securely integrates and connects a variety of energy devices. Built in data algorithms allow optimisation of your energy usage to minimise power bills. Marshall monitors your energy data with the help of analytics on real time basis.
Marshall Inverter Interfacing
Hybrid and solar inverters from a range of manufacturers can now be interfaced with Marshall Eco System. At this stage, inverter data is read via their Modbus RTU or TCP/IP interfaces. In some cases, inverter data is read via API. Data collected from inverters will be sent to the Marshall Cloud using REST API calls.
Similarly, the inverter can be remotely configured and controlled using Marshall Cloud. In this scenario, the values for the configuration and control parameters are sent to the inverter by the cloud. Data connectivity to the Marshall Black Box can be provided via its own Telstra 4G dongle. It is also possible for Marshall Black Box to communicate with the Marshall Cloud using site WIFI or site routers.
Features
- Enables customers to monitor a range of essential parameters such as solar production and consumption, Energy Balance, Export and Import, Site Aggregates, Battery Performance, and Meter Parameters in Real-Time (Customers can also monitor these three parameters in cyclic patterns. E.g.: Yearly, Monthly, Weekly and Daily)
- Allows installers to remotely configure inverter basic controls
- Provides the ability to interface inverters with virtual power plants (VPPs), distributed energy manufacturing systems (DERMS), and other smart grid/ network features
Marshall EV Interfacing
Marshall offers a range of charging solutions for both single-phase and three-phase EV chargers/EV charging stations. Now, Delta AC Max basic and AC Max Smart can couple with Marshall Black Box to provide four different types of charging modes: fast charge mode, eco charge mode, eco plus mode, and time of use mode.
Features
- Fast Charge Mode prompts a maximum charge rate from the customer and performs fast charging in a relatively short amount of time. Under single-phase conditions, the maximum allowable charge rate is 7 kW and under three-phase conditions, the maximum allowable charge rate is 22 kW.
- Eco Charge Mode also prompts a charge rate from the customer and performs EV charging minimizing the amount of energy required during the charging process. In Eco Charge Mode, Marshall Black Box diverts excess solar to the EV charger. However, in the absence of solar power, Marshall Black Box allows EV chargers to use grid power.
- Eco Plus Mode only allows EV chargers to use excess solar power. In absence of solar power. EV chargers automatically shut down.
- Time of Use Mode allows users to determine the charging time-period and the respective charge rate.
Marshall Ovida Interfacing
Marshall Eco-System enables OVIDA Energy Solutions to actively monitor the solar production, instantaneous power and power factor of its PPA sites. In this application, Marshall Black Box communicates with NMI-approved EM 24 Meter via its Modbus RTU interface through RS 485. Data collected from EM 24 is sent to the Marshall Cloud using REST API calls. Data connectivity to the Marshall Black Box is typically provided via its own Telstra 4G dongle. However, in certain scenarios, Marshall Black Box can communicate to the Marshall Cloud using site WIFI or site routers.
Features
- Enables customers to monitor, the solar production, instantaneous power and power factor in Real-Time (Customers can also monitor these three parameters in cyclic patterns. E.g.: Yearly, Monthly, Weekly and Daily)
- Provides billing options based on the energy generation
- Allows installers to remotely configure EM 24 basic controls.
Marshall BX 6.3 Interfacing
Marshall eco-system now offers single-phase and three-phase monitoring solutions to Delta BX 6.3 AC coupled battery system. In both single-phase and three-phase scenarios, the data from BX 6.3 battery is read via Modbus RTU through RS 485. Even though BX 6.3 could read grid power in a single-phase scenario, it is not capable of reading solar power values in either single-phase or three-phase. Therefore, the Marshall Black box reads solar power values using the ZECO 3-Phase Wi-Fi Meter.
Additionally, in a three-phase scenario, Marshall reads grid power values via the Delta P3 Meter and Delta Data Collector 1 (DC1) combination. Marshall hardware is fully capable of communicating with the DC1 Modbus TCP/IP interface through Wi-Fi (Typically generated by the Telstra 4G dongle).
Features
- Customers who are part of VPP managed by Nectr can monitor the critical parameters such as load, grid and solar power values of their Delta BX 6.3 Battery assets.
Plant Concept & Load Balancing
For a site where the connected EV Chargers must operate under a threshold of load value (kW) and imbalance of load (%), over the 3 phases, Marshall can be configured as Master and Slave.
Master Marshall connects to the ZECO Wi-Fi meter that monitors the Grid IMPORT/EXPORT power value through 3 x CTs, one on each phase. Each of the Slave Marshall is connected to an EV Charger and controls the charging power of this EV charger, based on allocation from Master Marshall.
Master Marshall allocates the charging power to each of the Slave Marshall, based on the difference of Allowed v/s Actual Load, per phase. It distributes the available power per phase, to each Slave Marshall. Slave Marshall controls the charging power of the connected EV charger, based on the lowest allocated power per phase.
Master Marshall will also re-allocate the charging power to each Slave Marshall, based on the slope of charging power over time. This is for non-OCPP-compliant EV chargers. For OCPP-compliant EV chargers, Master Marshall will use parameters like EV %SOC and Battery temperature, to allocate the charging power.
Master and Slave Marshalls, form a PLANT for the site and the dashboard for the PLANT shows dynamic Grid, Load, and PV power values. Also, each EV Charger’s status and charging power value are visible on this PLANT.
