The ICC (Inverter Control Centre) is the ideal solution for Pylon when used with Axpert in an on-grid solution. The main purpose of the ICC is to provide accurate monitoring and the ability to remotely monitor when used with an Axpert or InfiniSolar inverter. Alternatively, the ICC offers the ability to connect to the Pylontech BMS and by doing so the inverter can be controlled by the ICC based on the SoC reported by the BMS.
Adding the ICC greatly improves the cycling efficiency of the Axpert with Pylontech, as the ICC will use the SoC reported by the BMS of the Pylontech battery to control when the Axpert will use grid or battery, rather than relying on the Axpert measuring the very narrow battery voltage range. By using SOC based control, the system will be able to use the full rated capacity of the Pylontech battery if set to do so. This is especially useful for Axpert inverters because they can’t supply loads from mixed power sources. Maximising the energy available from the battery means the inverter will delay switching to the grid for as long as possible.
The ICC will therefore increase the overall value of the system as the full 80% DoD of the Pylontech can be used in a self-consumption battery cycling setup. This short guide demonstrates how to setup and access the ICC as part of your storage installation.
2) Options, capabilities and limitations:
Two components will be required when using ICC with a Pylon battery:
Inverter Control Centre Module (Raspberry Pi 3 b+) INCLUDED
Pylon Communication Cable for ICC INCLUDED
The ICC offers the following features:
Real-time monitoring of all the different power sources in use in a solar system (solar panels, batteries, grid power, etc).
All data is captured, stored and can be exported for a specific time period.
Specific monitoring of the batteries in use.
Can monitor up to 9 Axpert inverters in parallel.
Support for a host of different Voltronic inverters, including the new InfiniSolar 4 Super inverter.
Can monitor grid tie as well as hybrid inverters.
Support for Pylontech batteries with true SoC and voltage monitoring.
Hourly trend analysis of the load, the solar panels, the batteries as well as the utility consumption and/or production.
Easy setup with integrated hotspot and configuration wizard.
When using ICC and Pylon with the intention to implement battery control, a few things must be taken into consideration.
The ICC Pylon battery control function can only be used in an on-grid application, while in off-grid the ICC can only be used for monitoring. The on-grid control only comprises the battery cycling. The ICC will take over the cycling control logic and will not rely on the inverter logic. The parameters “to Battery” and ”to Grid” will be controlled by the ICC based on the SOC reported by the battery BMS. Please note: When using the ICC and Pylon for Grid connected self-consumption applications, the system will run the risk of the batteries shutting down in the event of a power failure. If the battery shuts down due to the low-voltage cutout protection, the battery will have to be manually turned on once a charging source is available. This can be done by simply pressing the RED button on the master battery. During grid connected cycling, the battery will be limited to 80% DoD and during a grid outage the DoD will be limited to 90%.
