To protect your panels, consider surge protection like Citel DS72-RS-120 or Delta LA-302, and proper grounding. Following guidelines and using quality equipment can bolster safety.
[pdf] Mutual influence may be driven by different models and operating mechanisms of grounding systems in multi-in- one substations. Even equipment damage and personal injury will occur in the event of a short-circuit.
[pdf] Lightning protection function: In the combiner box, lightning protection devices such as lightning arresters or surge protectors are usually installed.
[pdf] For the solar panel grounding, general use 40 * 4mm flat steel or φ10 or φ12 round steel, and finally buried depth of 1.5m underground, the grounding resistance of the PV module is not less than 4Ω.
