Connector Type Defines the electrical or fluid connection used in the system—includes plug types like MC4, Anderson, SAE, XT60, as well as ring terminals and hard-wired or quick-connect setups for solar, batteries, HVAC, and heating applications.	MC4 Industry-standard PV connector for safe, weatherproof DC wiring.
Protection Rating [IP] IP (or \"Ingress Protection\") ratings are defined in international standard EN 60529 (British BS EN 60529:1992, European IEC 60509:1989). They are used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture.	IP67 Fully dustproof and water-resistant against temporary immersion.
Max. PV input voltage [V] Maximum PV voltage, which is an absolute limit of the voltage of PV panels connected in series, and “nominal PV power”. If more wattage is available from the panels, the controller won\'t use it, it will just limit the current to what it can handle.	1000V
Warranty Normally covers, manufacturing defects, durability issues, or equipment failure. The warranty typically covers the cost of replacing the faulty or damaged panel with a new working one. Please refer to the Warranty Documents of the product on the Manufacturer s webpage.	2 Years
