Specifications Item type: Solar Controller Style: 28 UK Material: Plastic Application: Suitable for small solar systems for household, industries and commerce System voltage: 12 V / 24 V (auto recognition) Maximum photovoltaic voltage: 23 V for 12 V battery; 46 V for 24 V battery Boost voltage: 14.4 V Floating voltage: 13.7 V (default value, adjustable) Disabling cut off voltage: 10.7 V (default value, adjustable) DIS recovery voltage: 12.6 V (default value, adjusted setting) Trache de re: Re: 13 V Light controlled influence: has a delay Light deactivation threshold: 8 V PV panel (controlled light stop has a delay) USB output: 2 USB outputs, 5 V / 2.5 A (maximum) Standby current: (specification provided) Working temperature: 35 to 60 C Package contents 1 x Solar Controller 1 x User manual Installation and usage notes The controller automatically recognizes 12 V or 24 V systems. On first installation make sure the battery has sufficient voltage for correct recognition. Install the controller as close as possible to the battery to minimize voltage drop caused by long wiring which can affect system sensing and judgment. The light control function contains an internal delay; configure thresholds and timings as required for your application. Practical use scenarios Off grid cabin lighting and battery charging: manage panel input and battery charging for LED lighting and small appliances while monitoring cumulative energy production. Remote signage or sensor power: control charging for 12 V or 24 V battery systems that power lighting and monitoring equipment, with USB charging available for auxiliary devices. Small commercial or workshop power: maintain and protect battery banks used for backup lighting, instrumentation, or small DC loads with staged charging and overcurrent protection. This controller is intended for use in small solar installations where reliable charge management, basic protections, and convenient USB charging are required.
