The standards for matching solar panels with power station are determined by several key factors:

1. Internal Battery Capacity of the Portable Power Station

The larger the internal battery capacity, the longer it takes to charge when paired with low-power solar panels, leading to poor user experience.

Example:

Explorer 500 has an internal battery of 518Wh, and Explorer 2000 Pro has an internal battery of 2160Wh. If both are charged using 100W solar panels, the theoretical full-charge time (for simplicity, not including charging efficiency) would be:

Explorer 500: 518Wh / 100W = 5.18 hours (within an acceptable range)

Explorer 2000 Pro: 2160Wh / 100W = 21.6 hours (long charging time, poor experience)

For high-capacity devices like the E2000 Pro, using low-power solar panels (e.g., 100W) results in unreasonably long charging times, affecting the experience. The Explorer 2000 Pro is ideally paired with 200W-1200W solar panels.

Conclusion: The battery capacity of the power station is a key factor in selecting the solar panel.

2. Charging Specifications of the Portable Power Station

The charging specifications (maximum voltage/current range allowed for solar charging) determine how much power and how many solar panels can be used. If the portable power station's charging specifications permit, larger solar panels and more panels can be connected.

Example:

Explorer 2000 Pro solar charging specs: Supports 17.5V~60V / 12A, supports 2 inputs (max 24A), max 1400W. Because the design charging voltage is limited to 60V, it supports 3 solar panels connected in series (1 panel is 18V, so 3 panels would be 54V, within the range).

Thus, it’s important to match solar panels that align with the voltage and current specifications of the portable power station to ensure efficient charging.
