Contrary to popular belief, quality photovoltaic inverters don't automatically shut off during rainfall. 2 inches per hour – far beyond typical storm. While most modern inverters have IP65 ratings (dust-tight and protected against water jets), prolonged exposure to heavy rain can still cause: "Think of inverter protection like a good umbrella – it's not just about surviving a drizzle, but weathering storms. " - Solar Maintenance Expert, NREL. Example: The installation position is in a dip or the installation height fails to meet requirements, it may lead to the inverter or cable port being exposed to water. Solution: Refer to the product manual for installation spacing, the bottom of the conventional installation inverter is≥500mm from. However, outdoor environments expose solar inverters to harsh conditions such as dust, rain, humidity, heat, pollution, and voltage fluctuations. This is where IP65 protection plays a critical role.
