Product Q&A

Q:Q1: What material is the grid-connected box made of, and can it be used outdoors?

A1: It is made of thickened galvanized steel plate with anti-rust spray coating. It reaches IP65 waterproof and dustproof rating, resistant to rain, dust and coastal salt fog, suitable for long-term outdoor installation of solar power stations.

Q:Q2: What safety protection functions does this distribution box have?

A2: It is equipped with circuit breakers and lightning protection modules, supporting multi-protection including over-current, over-voltage, short circuit and surge lightning protection. The internal AC and DC circuits are separated to avoid electromagnetic interference and electric leakage risks.

Q:Q3: Is it convenient to install and replace internal electrical accessories?

A3: Standard pre-opened cable holes with sealing rubber rings are reserved for quick wiring. The internal DIN rail design allows free disassembly of breakers and lightning protectors. The flip front cover enables direct inspection without removing the whole cabinet.

Q:Q4: What solar power scenarios is this combiner box applicable to?

A4: Widely used for household rooftop solar systems, commercial industrial photovoltaic power stations, off-grid and grid-connected solar energy projects, matching most mainstream solar panel combinations.

Q:Q5: Will the cabinet deform or rust easily after years of use?

A5: Reinforced folded edge structure enhances compression resistance to prevent deformation during transport. Multi-layer electrostatic anti-corrosion paint effectively isolates humid air and rainwater, greatly slowing rust and oxidation.
