Description
DC DC Protective Panel
Features:
• Number of inputs: 4 inputs for connecting photovoltaic strings.
• Operating voltage: Up to 410 volts DC (open circuit voltage).
• Operating current: Up to 13 amps per input.
• Surge Protection: Triggers at 415 volts DC.
Main components:
1. Fusible two-pole fuses (16A DC) – For overload and short circuit protection.
2. Two-pole arrestor groups (415V DC) – For surge protection, with automatic deflection of excess voltage to ground.
3. Two-pole automatic fuses (25A DC) – Automatic overload shutdown.
4. Ground Rail – Provides secure grounding of the system.
Working principle: In events such as thunderstorms, when the voltage in the photovoltaic wires exceeds 415V, the arresters instantly connect the positive and negative conductors to ground. This causes the fuses to trip, which disconnect the connection between the inverter and the strings, providing protection for the inverter input and connected devices.
Compatibility: The switchboard is ideal for photovoltaic systems with inverters from brands such as Growatt, Deye, SAJ, as well as others with MPPT inputs, maximum current up to 22 amperes and voltage up to 500 volts.
Application: Particularly suitable for systems with inverters such as Growatt SPF6000ES Plus, which have two MPPT inputs, protecting each of them individually.
The dashboard offers reliable and effective protection for your PV system, ensuring smooth and safe operation of the inverter and connected devices.
