1. Introducció
The EPEVER 40A MPPT Solar Charge Controller, model 4210AN, is an advanced Maximum Power Point Tracking (MPPT) charge controller designed for off-grid solar systems. It automatically identifies 12V/24V system voltages and is negatively grounded. This controller supports various battery types, including lead-acid (sealed, AGM, gel, flooded) and lithium batteries, and features automatic limitation of charging current and power. It offers high tracking efficiency of no less than 99.5% and a maximum DC/DC conversion efficiency of 98%.
2. Informació de seguretat
- Ensure proper grounding of the controller before any connections.
- Always connect the battery first, then the solar panels (PV array), and finally the load. Disconnect in the reverse order.
- Verify correct polarity for all connections to prevent damage to the controller and connected devices.
- Instal·leu el controlador en una zona ben ventilada, allunyada de materials inflamables i de la llum solar directa.
- Use appropriate wire gauges for all connections to handle the expected current.
- No intenteu desmuntar ni reparar el controlador vosaltres mateixos. Poseu-vos en contacte amb personal qualificat per al servei tècnic.
