Solar controller A practical solar charge controller designed to manage charging for common battery types and to improve solar panel to battery conversion efficiency. Simple compatibility options and automatic voltage identification reduce setup time and potential wiring errors. Key benefits Automatic voltage detection and simple setup: detects 12 volt or 24 volt battery systems automatically, avoiding manual configuration. Supports multiple battery chemistries: available models support standard lead acid style charging with automatic 12V or 24V identification, lithium ion batteries, and lithium iron phosphate batteries. Improved solar conversion: regulates charging to make better use of solar panel output and increase effective energy transfer to the battery. Flexible deployment: suitable for small off grid systems, recreational vehicles, boats, and remote equipment that rely on solar charging. How it solves common problems Eliminates manual voltage selection errors with automatic 12V and 24V detection. Provides correct charging behavior for different battery chemistries by choosing the appropriate model for the battery type. Helps reduce wasted solar energy by optimizing the controller role between panels and battery. Main attributes Function: solar charge control to manage charging and improve conversion from solar panels to battery storage. Compatibility: supports 12V and 24V battery systems with automatic identification; separate models for lithium ion and lithium iron phosphate batteries. Models are identified as b1, b2, and b3. Model mapping: b1 for 12V or 24V automatic identification charging, b2 for lithium ion battery charging, b3 for lithium iron phosphate battery charging. Installation: designed for integration into typical small solar charging setups. Typical use scenarios Off grid cabin or shed: connect solar panels to the controller and a battery bank to maintain reliable charging without complex configuration. Recreational vehicle or boat: manage charging for on board batteries during daylight hours and simplify setup across 12V and 24V systems. Remote power equipment: power and maintain batteries for remote monitoring, lighting, or communication devices using a solar array. Ordering and model selection Choose the model that matches your battery chemistry and system voltage: b1 for automatic 12V or 24V systems, b2 for lithium ion battery systems, b3 for lithium iron phosphate battery systems. This controller is intended for use in solar charging systems where proper selection of battery chemistry and voltage is required to ensure correct charging behavior and improved conversion efficiency.
