Solar photovoltaic and portable energy storage products have seen fast export growth in recent years. Compared to ordinary electronics, this category carries several additional layers of testing requirements — here's a breakdown.
What Makes This Category Distinct
Solar/energy storage products typically combine "large-capacity batteries," "independent power generation/supply functionality," and "extended continuous operation" — which stacks the testing requirements accordingly:
- Battery testing (UN38.3, etc.): energy storage products generally use large-capacity lithium battery packs, making battery safety testing a core item — and the larger the capacity, the stricter the transport compliance requirements tend to be
- Electrical safety: circuits involving power output and charge/discharge management need to meet applicable electrical safety standards
- EMC: as electronic equipment, these products also need to meet electromagnetic compatibility requirements
- Solar-panel-specific standards: solar panel products also involve industry-specific standards like IEC 61215 (performance) and IEC 61730 (safety), a different standards framework than typical battery products
Details That Often Get Missed
- Transport compliance for large-capacity batteries: portable power stations typically have far greater battery capacity than ordinary consumer electronics, and air/sea freight compliance requirements for large-capacity lithium batteries (UN38.3 reports, packaging grades) are stricter than for smaller battery products
- Whole-system certification for multi-component products: if the product is a system combining "battery + inverter + charge controller," it may need each component tested separately, or it may need integrated system-level testing — depending on the product's actual configuration
- Links to local subsidy/market-access policy: in some countries, energy products face additional certification requirements tied to local subsidy programs or market-access policy beyond baseline safety certification — worth checking against the target market's current policy ahead of time
Frequently Asked Questions
Q: Does a portable power station count as an ordinary battery product? A: Not entirely — while the core testing logic is similar, because capacity is generally much larger and involves charge/discharge management circuitry, the testing scope is typically more comprehensive than for a standard consumer electronics battery.
Q: Do solar panels need battery testing? A: A solar panel itself is a power-generation component with no battery, so it's tested primarily against solar-specific standards (IEC 61215/61730). But if the product is an integrated "solar panel + energy storage battery" kit, it needs to satisfy both the solar and battery testing requirements.
