New functionalities in the latest xtender system update R672

At the online keynote, our CTO Pierre-Olivier Moix mentioned the innovation as a core value at studer, but not simply focusing of creating the next range of new products but also improving existing devices to meet the needs of our specifics markets.  

In the latest xtender software update there are relevant elements that will contribute to the xtender family to be even more versatile for your current and future projects.  

Along with the incorporation of the new variotrack, vt 40, this update brings a further step in the integration of communicating lithium batteries in systems with ac coupling production. We have incorporated the smart management of ac coupled sources for offgrid systems with lithium batteries. More and more clients are taking advantage of mixing DC and AC coupling generation (especially solar) to maximize the system efficiency. In an offgrid system, the xtender can manage the ac coupled source in the output, according to battery voltage. In systems with lithium batteries, the xcom CAN integrates for now on a smart management of the ac coupled generation according to the battery status, communicated by the battery BMS.  

In systems with communicating lithium batteries, the configuration remains straightforward and centralized by the xcom CAN settings. There are 3 new parameters in the xcom CAN advanced settings menu that will help easily configuring ac coupling with lithium batteries. The rest of the devices in the system, including xtender inverters, will follow up these settings without any further configuration required.   

The frequency control of the AC output is again the responsible of controlling the AC coupled source as represented in the following graph:  

You could find further details in the Xcom CAN manual and the AC coupling section in our FAQ.  

In addition to these features, the multicast option by phases (L1, L2 and L3) has been also integrated in the CAN protocol for communication, making possible to easily address all the devices in one phase from the external CAN communication system.  

The system update can be downloaded from the download page in our website, under the “Software and Updates” section. The update is a simple procedure and you can find a detailed description in the FAQ section.   

We are looking forward to seeing your next offgrid installation with both DC and AC coupling sources. Do not hesitate to contact us in case of any further inquiry.
