SBB 20 C PRO – Charging booster and MPPT solar charge controller for caravans

The SBB 20 C PRO combines a charging booster and MPPT solar charge controller in a single device for caravan applications. The onboard battery is charged via the alternator while driving and seamlessly supplied by solar power at the campsite. The adjustable charging current allows for use with virtually any towing vehicle, regardless of fuse rating or cable length. AGM, GEL, wet-cell, lithium, and sodium batteries are supported. Configuration and monitoring are performed via Bluetooth, CI bus, CAN bus, or directly on the device. ECE-R10 certification ensures safe operation while driving.

Areas of application

• Caravans and motorhomes with charging via alternator and solar power

• Adjustable charging current: 5, 9, 13, 15 or 20 A

• MPPT solar charge controller for maximum solar yields on the go and at the campsite

• Suitable for lithium and sodium batteries

Performance

• Charging current up to 20 A, vehicle-specific and adjustable

• MPPT solar input 12 to 48 V, solar input up to 20 A

• Suitable for on-board batteries from 10 to 400 Ah

• Automatic switching between alternator and solar charging

Security

• Protection against reverse polarity, overheating and overvoltage

• Starter battery undervoltage protection

• PV overload and PV overvoltage protection

• ECE R10 certified for safe operation while driving

Control and comfort

• Bluetooth control via the connECTIVE app

• Integration via CI and CAN bus

• Silent operation thanks to passive cooling

• Battery temperature sensor for optimized charging characteristics

The SBB 20 C PRO enables self-sufficient energy supply without shore power through the combined use of alternator and solar energy while simultaneously protecting the vehicle's electrical system.
