Citel PV surge protectors are DIN mount and are ideal for placement inside combiner boxes.
The Citel DS210DC surge protector is designed to protect 12V, 24V, 48V and 150V DC power lines for an off-grid PV system. The maximum voltage surge protector should not be exceeded in any operation conditions. Use the next higher rated surge arrestor if necessary. The Citel DS210DC surge protectors protect the charge controller and other system electronics. The Citel DS210DC surge protectors automatically reset after each lightning surge or electrical transient. The Citel DS210DC surge arrestors offer much the best protection for charge controllers and inverters in low-voltage DC systems.
