Sterling Battery-to-Battery Charger + 350W Solar Charge Controller (BBS1230)

Sterling Battery-to-Battery Charger + 350W Solar Charge Controller

The Sterling BBS1230 combines a battery-to-battery (B2B) charger with an integrated 350W solar charge controller in a single unit — ideal for campervans, motorhomes, and caravans running a dual battery setup. The B2B charger draws charge from the vehicles alternator to intelligently charge the leisure battery, while the solar controller manages solar panel input simultaneously.

Key Features

• Sterling BBS1230 — combined B2B charger and solar controller
• Battery-to-battery charging from vehicle alternator
• Integrated 350W solar charge controller
• Intelligent multi-stage charging for lithium, AGM, and gel batteries
• Single unit — reduces wiring complexity

Why Use a Battery-to-Battery Charger?

Modern vehicles with smart alternators and EFB/AGM starter batteries do not fully charge leisure batteries via a simple split charge relay. A B2B charger intelligently manages the charging process, ensuring the leisure battery receives a proper multi-stage charge from the alternator — significantly improving leisure battery health and capacity over time.

Installation

Professional installation recommended. Ensure cable sizing, fusing, and connection locations are correct for your installation. Follow Sterlings wiring guidance supplied with the unit.
