Pylontech H48074 + SC0500 high-voltage compatibility

Short answer

Yes, since firmware 2.8, on generation 2 and the Lite: the device reads high-voltage packs driven by a controller such as the SC0500 through its Console port, and detects the high-voltage pack by itself. The support was built from real controller readings, but an H48074 has not yet been connected to a Pylon-Monitor.

Thank you for your message and your kind words, and sorry for the delay.

Yes: since firmware 2.8, Pylon-Monitor reads high-voltage Pylontech packs driven by a controller (BMS) such as your SC0500, through its Console port. It detects by itself that it is a high-voltage pack. You get state of charge, voltage, current, temperatures, every module and every cell, alarms and status.

To be fully transparent: this high-voltage support was built from real readings of Pylontech controllers, but we have not yet had an H48074 pack connected to a Pylon-Monitor. If your controller answered differently, the device has a diagnostic page that collects its replies, and we would adapt the firmware.

Merci pour votre message et vos compliments, et désolés pour le délai de réponse.

Oui : depuis le firmware 2.8, le Pylon-Monitor lit les packs Pylontech haute tension pilotés par un contrôleur (BMS) comme votre SC0500, par son port Console. Il détecte tout seul qu'il s'agit d'un pack haute tension. Vous obtenez l'état de charge, la tension, le courant, les températures, chaque module et chaque cellule, les alarmes et les états.

Pour être totalement transparents : ce support haute tension a été développé à partir de relevés réels de contrôleurs Pylontech, mais nous n'avons pas encore eu de pack H48074 branché à un Pylon-Monitor. Si votre contrôleur répondait différemment, le boîtier dispose d'une page de diagnostic qui collecte ses réponses, et nous adapterions le firmware.

To be precise: high-voltage support is on generation 2 units (with a screen, shipped from 5 September 2026) and on the Pylon-Monitor Lite. Units shipped before that date read the low-voltage US series only. The controller reports no state of health and no cycle count, so those two lines show a dash.

Original · Français

Pour être précis : le support haute tension concerne les boîtiers de génération 2 (avec écran, expédiés à partir du 5 septembre 2026) et le Pylon-Monitor Lite. Les boîtiers expédiés avant cette date lisent uniquement la série US basse tension. Le contrôleur ne donne ni état de santé ni nombre de cycles : ces deux lignes affichent donc un tiret.
