The LV-HUB solves this by acting as a \u003cstrong\u003ecommunication concentrator\u003c\/strong\u003e: it collects data from all connected battery strings via CAN or RS485, aggregates it, and presents a single BMS data feed to the inverter — as if the entire bank were one battery. The inverter can then make precise charge\/discharge decisions based on the overall bank status rather than a single module's data, \u003cstrong\u003eprotecting every cell in every string\u003c\/strong\u003e and maximising the usable capacity of the whole system.\u003c\/p\u003e\n    \u003cp style=\"margin:0;\"\u003eThe LED indicators on the LV-HUB face-panel provide instant commissioning feedback: the binary-coded NUMBER\/BIN LEDs (1–4) display the count of connected and online battery groups, making it straightforward to verify that all strings have been correctly recognised during start-up.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- FEATURE CARDS --\u003e\n  \u003cdiv style=\"display:grid;grid-template-columns:repeat(auto-fill,minmax(260px,1fr));gap:16px;margin-bottom:30px;\"\u003e\n\n    \u003cdiv style=\"border:1px solid #d4ecea;border-radius:8px;padding:18px;\"\u003e\n      \u003cdiv style=\"font-weight:700;font-size:15px;color:#008377;border-bottom:2px solid #008377;padding-bottom:6px;margin-bottom:10px;\"\u003eDual-Protocol: CAN and RS485\u003c\/div\u003e\n      \u003cp style=\"margin:0;font-size:14.5px;\"\u003eThe LV-HUB supports both \u003cstrong\u003eCAN Bus (500K baud, 0\/120Ω terminal resistance)\u003c\/strong\u003e and \u003cstrong\u003eRS485 (9600\/115200 baud)\u003c\/strong\u003e communication standards.

The LV-HUB is only required when you exceed 16 US5000 modules in a system and need to connect multiple strings. For RS485 multi-string connections with US5000 modules, an LV-HUB is also not required — refer to the US5000 User Manual for the RS485 multi-group wiring diagram.

Pylontech permits mixing of compatible 48V series modules within the same system, but enforces a strict \u003cstrong\u003emaster battery priority order\u003c\/strong\u003e: US5000 and US5000-B take precedence, followed by UP5000\/US3000C\/US2000C, then US3000\/US2000. Mixed strings should follow this hierarchy and it is strongly recommended to use the same model within each individual string. Never mix LV (48V) and HV (high-voltage) battery series on the same LV-HUB.

It will not alarm if a new group is added — only if an existing group is lost. Under normal operation with all groups online, the STATUS LED is green. If you see a red STATUS LED during operation, check that all battery strings are powered on and that no communication cable has become disconnected. The binary-coded NUMBER\/BIN LEDs (1–4) will show fewer online groups than expected, helping you identify which string has dropped.

This means the inverter can apply charge and discharge limits that protect every cell in every string, not just the module closest to the inverter.
