How many solar panels can I use at the same time with DELTA Max?

It depends on the total voltage and watts of solar panels you choose. As long as the solar panels use MC4 connector and its voltage and current are under 11-100V, 10A max range.

What’s the max input for DELTA Max?

When charging DELTA Max and its extra battery together, you can reach 3600W max charging speeds by combining any two methods of AC, solar and Smart Generator. For DELTA Max single unit, you can recharge it at standard wall outlets (1800W max), or combine AC and solar charging to reach max 2000W charging speeds.

How does the Emergency Power Supply (EPS) work? And how fast is it?

When your portable power station is plugged into the wall, any electronics plugged into it are powered from the grid and not its battery. When power from the grid stops, as in a blackout, the power station automatically switches to battery power within 30ms.

What's the water-resistance rating for this product?

DELTA Max is not water-resistance, so it should be kept away from liquids. Or if you're looking for a water-resistance solution, you can purchase the DELTA Max case for water-resistance protection.
