Description
Maximum MPP versatility with fast connection
The Weidmüller PV Next Fireman Switch 2MPP WM4C Represents the highest standard in fire protection to solar energy. By managing Two independent MPP followers, It is ideal for roofs with different orientations or shadows. Its great added value is the combination of this double capacity with Fast connectors WM4C, which reduces the labor time and guarantees a sealing of hermetic factory, vital for Longevity of photovoltaic installation.
This intelligent system eliminates manual error management. If he AC supply interrupts, the equipment opens the circuit of Duty current (DC) Immediately. Once the network is restored, the automatic recirement Activates the system without technical intervention. In addition, its robust box Polyester with fiberglass Supports extreme weather conditions and protects electronics through a Safety thermal sensor that disconnects the equipment if it detects internal temperatures higher than 100 ° C..

Frequently Asked Questions (FAQ)
- What advantages does the 2MPP WM4C model have on the rest? It is the most complete model: allows managing Two panel orientations independently and it is installed in minutes thanks to its Plug & Play connectors, without the need to open the equipment.
- Is it compatible with standard MC4 connectors? Completely. The terminals WM4C from Weidmüller They are designed to be 100% compatible with the standard Mc4, ensuring a secure connection and without hot spots in your photovoltaic system.
- How does fire disconnection work? The switch monitors the alternating current of the building. If firefighters cut the general light, the PV NEXT switch automatically cuts the duty how low from the roof.
- Does the rearme system require maintenance? No, it’s totally automatic. The device detects the return of the electrical network and, after a brief security check, reconnects the panels to continue with the generation of self-consumption.
- Can it be installed in extreme climate areas? Yes, your envelope reinforced polyester It is superior to traditional plastic boxes, offering high resistance to UV, corrosion and extreme temperatures.
