Product overview A compact MPPT solar charge controller board designed for small solar systems and DIY projects. Optimized for charging lithium ion titanate battery packs with a maximum charging current of 1A. Provides improved energy harvesting from solar panels and consistent charge management tailored to LTO battery chemistry. Key benefits More efficient charging than simple regulators by using MPPT tracking to extract higher power from solar panels under varying light conditions. Designed for lithium ion titanate batteries to follow appropriate charge behavior and maintain battery performance for intended applications. Small, PCB style module that is easy to integrate into prototypes, sensor nodes, portable devices, and custom battery systems. Stable 1A charging current suitable for small battery packs and low power applications where controlled charging is required. What this module does and how it solves problems Maximizes solar input: The MPPT algorithm continuously adjusts operating point to capture more energy from the panel when irradiance or load conditions change. Matches battery needs: Charge control is configured for lithium ion titanate chemistry so charging follows the charging profile appropriate for this type of battery. Simplifies integration: The module combines regulation and charge control in one compact board, reducing wiring and component count in small systems. Compatibility and function Compatible with lithium ion titanate battery modules and a wide range of small solar panels designed for low current charging. Rated for a maximum charge current of 1A. Suitable for small battery capacities and low power storage applications. Function set includes maximum power point tracking, regulated charging output, and straightforward input and output connections on a PCB module. Form factor and materials Compact printed circuit board with standard electronic components for power conversion and control. Designed for mounting in enclosures or on project boards in hobby, academic, or light commercial prototypes. Connections provided on the board for solar input and battery output to simplify wiring. Performance highlights MPPT control improves energy capture when sunlight varies through the day or under partial shading. 1A charge current provides predictable, controlled charging for small LTO packs and reduces the need for multiple external components. Stable operation for low power systems where consistent charging behavior is important. Typical applications Remote sensor power: Solar charging for environmental sensors, telemetry nodes, and monitoring equipment where frequent maintenance is not possible. Portable lighting and backup: Charging small lithium ion titanate battery packs for portable lamps, emergency lighting modules, or small backup power systems. Education and prototyping: Solar power experiments, proof of concept projects, and small DIY energy systems that require MPPT charging and LTO battery compatibility. What to consider before Verify that the battery chemistry is lithium ion titanate and that a 1A maximum charge is appropriate for the battery capacity. Confirm that the chosen solar panel voltage and current fall within the practical operating range for a low current MPPT regulator module. Plan for mounting and enclosure to protect the board in outdoor or humid environments if used outside. This MPPT solar charge controller board offers a compact, efficient solution for integrating small solar panels and lithium ion titanate batteries into low power systems and prototypes where controlled charging and improved energy harvesting are required.
