Compact 20 A MPPT solar charge controller with built‑in Bluetooth and Victron BatteryLife for reliable battery protection and maximum energy harvest.

• Ultrafast MPPT Technology: This 20 A MPPT solar charge controller is designed to deliver the highest possible energy yield using high‑speed Maximum Power Point Tracking for superior performance, including excellent low‑light results.
• Inbuilt safety protection: Fully equipped with an extensive range of safety features, including battery reverse polarity protection, load short‑circuit protection, low‑voltage load disconnect and battery overheating monitoring via an internal temperature sensor; self‑diagnostic fault reporting via high‑intensity LEDs.
• Intelligent BatteryLife function: To prevent complete discharge and avoid potentially permanent damage, the BatteryLife algorithm monitors state of charge and limits excessive loads to extend battery lifetime.
• Inbuilt Bluetooth and live data: This SmartSolar charge controller features built‑in Bluetooth allowing monitoring with VictronConnect. Live data transmission provides real‑time solar panel voltage, current and power; data logs store system activity for the past 30 days and include total energy counters.
• Load configuration and remote options: Choose from pre‑set load management programmes or create a custom profile. Optional MPPT control panel (sold separately) and VE.Direct/USB connectivity are supported for local display and configuration.
