This controller is designed to efficiently manage power from solar panels to charge various battery types, including Lead-Acid (Sealed, Gel, Flooded) and Lithium (LiFePO4, Li[NiCoMn]O2) batteries, in 12V or 24V automatic identification systems. It features advanced Maximum Power Point Tracking (MPPT) technology for optimal energy harvesting and includes multiple electronic protections to ensure system safety and longevity.

2. Informació de seguretat

ADVERTIMENT:

• Risk of Electric Shock: Do not remove the cover. There are no user-serviceable parts inside. Refer servicing to qualified service personnel only.
• Risc de descàrrega elèctrica: quan la matriu fotovoltaica està exposada a la llum, subministra un volum de CCtage to this equipment. Always ensure solar panels are disconnected or covered before working on the system.
• Hot Surfaces: To reduce the risk of burns, do not touch the controller during operation as surfaces may become hot.

3. Característiques clau

• MPPT Technology: High tracking efficiency up to 99.5% and peak conversion efficiency of 98%, maximizing energy from solar panels.
• Battery Compatibility: Supports Sealed (AGM), Gel, Flooded, LiFePO4, Li(NiCoMn)O2, and user-defined battery types.
• Carregant Stages: Four stages of charging (bulk, absorption, float, Equalization) to prolong battery lifecycle.
• Display & Control: Integrated LED indicators and LCD display for monitoring PV/Battery/Load status. Five buttons for easy parameter adjustment and browsing.
• Communication: RS485 interface for connecting accessories like MT50 remote meter, BLE/WiFi Adapter (APP), or PC software for detailed monitoring and parameter modification.
• Protections: Built-in protections against reverse polarity, overcharging, over-discharging, overload, short-circuiting, and reverse current.
• Grounding: Common negative grounding design for wide application in various systems (e.g., communication base stations, household systems, RV solar systems).
