Growatt LV (GBLI-series)
Compatible Growatt LV batteries~
- Growatt GBLI6532 ✅ — confirmed live for weeks against a Solis S6-EH1P8K-L-PLUS inverter
- If you try another GBLI-series pack, please add it to this list!
Software configuration~
For this battery type, use the option called "Growatt LV (GBLI-series) battery via CAN, 500kbit/s" under the "Battery Protocol" setting.
Wiring notes~
The GBLI6532 has three RJ45 sockets. Use PCS (the inverter-facing one), not Link-In/Link-Out — those carry the inter-battery bus on different pins and will silently not work.
| Pin | Signal |
|---|---|
| 4 | CAN_H |
| 5 | CAN_L |
| 7 | PCS-WAKE− |
| 8 | PCS-WAKE+ |
WAKE (pins 7/8) is documented for waking the pack from a non-Growatt inverter, but it is not needed — a CAN-only connection (just pins 4/5) is enough to both enable and revive the pack, confirmed by wiring a cable with WAKE deliberately left disconnected.
A standalone battery still needs the correct master-select plug fitted in Link-In/Link-Out, or it may never enumerate on the bus.

CAUTION
Working with high voltage is dangerous. Always follow local laws and regulations regarding high voltage work. If you are unsure about the rules in your country, consult a licensed electrician for more information.
