MPPT Solar Controller for OffGrid Photovoltaic Systems Overview This MPPT solar controller optimizes power harvest from solar panels and coordinates panels, batteries, and loads in offgrid photovoltaic systems. It detects solar panel output in real time and tracks the voltage current value V1 to charge the battery at maximum power output. The controller serves as the core control component in offgrid PV installations. Key benefits Maximizes energy harvest by tracking the voltage current value V1 for effective maximum power point tracking. Improves system stability and battery life by coordinating charging and load control for consistent performance. Reduces risk of component failure through comprehensive protection features and automatic current limiting. Easy monitoring and adjustment using the builtin LCD and control buttons; includes a 5V 3A USB output for auxiliary charging. Main features Item type: MPPT Solar Controller designed for offgrid use. System voltage: 12V and 24V adaptive for flexible installation. No load loss: approximately 0.4W. Realtime PV detection and MPPT algorithm that tracks V1 to deliver maximum available charging power. LCD display showing operating state, running parameters, and configurable control settings. Parameters are viewable and adjustable via front panel buttons. 5V 3A USB port for charging small devices or powering accessories. Current limiting charging mode: when panel power or charging current exceeds rated values, the controller automatically reduces charging power to maintain safe rated current. Fanassisted heat dissipation to manage temperature under heavy load and extended operation. Protection and maintenance Input power limit to prevent overdrive. Protection against excessively PV input voltage. Photovoltaic input short circuit protection. Photovoltaic input reverse connection protection. Load over power protection. Load short circuit protection. Night reverse prevention to avoid battery discharge through the panel at night. TVS surge protection and over temperature protection to reduce risk from installation errors and system faults. Battery compatibility Supports multiple charging procedures for colloidal battery, sealed battery, open battery, and lithium battery types, allowing use with common battery chemistries in offgrid systems. Typical applications Household photovoltaic power systems for remote cabins, cottages, and offgrid homes. Communication base station power supply where stable, autonomous energy is required. Highway intelligent monitoring systems and landscape lighting installations requiring reliable day and night operation. Why choose this controller This MPPT controller offers realtime MPPT tracking, configurable controls via an LCD interface, robust protection features, and adaptive 12V/24V operation to suit a wide range of offgrid photovoltaic setups. It is designed to maximize charging efficiency while protecting system components and simplifying maintenance.
