IP65 rating
By Priya Nair · Last reviewed An ingress-protection classification meaning fully dust-tight (6) and protected against water jets from any direction (5). For balcony solar, IP65-class enclosures are the practical benchmark for microinverters and batteries that live outdoors year-round.
Why it matters
An outdoor battery or inverter without a stated IP rating is a red flag: rain, dust and condensation are its daily operating environment. IP65 alongside a specified operating temperature range signals hardware genuinely engineered for the balcony rather than adapted from indoor products.
