Hello everyone,
I’m encountering a persistent and serious issue with my SmartSolar MPPT 100/50, firmware v1.64, used aboard an off-grid sailboat:
- Serial number: [moderator edit: removed SN]
- Backup unit (same issue): [moderator edit: removed SN]
Every morning (after a night without solar input), the MPPT becomes invisible via Bluetooth, and requires a manual power cycle to wake up.
I’ve already:
- Updated to latest firmware upon installation
- Ensured continuous low-level loads overnight (LEDs, USB chargers, fridge)
- Measured normal voltages (LiFePO₄ system with JK BMS)
The same problem occurred with my previous unit.
I now suspect a firmware or deep sleep bug related to v1.64.
I’m currently at anchor (no shore power), and do not have a VE.Direct cable with me.
Can anyone confirm:
- Whether Victron is aware of this issue (v1.64)?
- If there’s a safe way to downgrade or patch via BT?
- Any known workaround to ensure stable operation?
I’ve contacted Victron support but received a generic reply saying they’ll answer “within 5–7 business days”, which is frankly disappointing given the severity of the bug.
Any help is greatly appreciated.
Thank you in advance.
