EcoFlow ZMS331-2-AKIT-2 Rigid Solar Panel Set 2 x 100 W, Monocrystalline, Black, IP68

The EcoFlow ZMS331-2-AKIT-2 is a 200W rigid solar panel kit designed for fixed off-grid installations. It consists of two panels that provide a combined 200 W output for charging compatible battery systems. The monocrystalline cells reach 23% efficiency, maximizing energy yield relative to the panel surface area. This model is intended for permanent mounting on surfaces such as roofs, trailers, or caravans, serving as a stable power source for outdoor applications where portability is not required.

Each panel measures 586 mm in width, 980 mm in depth, and 30 mm in height. Each unit weighs 6.2 kg and features a rigid frame with pre-drilled mounting slots. The panels have an IP68 rating, making them dust-tight and water-resistant for long-term outdoor exposure. Electrical connection is provided via an MC4-compatible connector, ensuring compatibility with most solar controllers and power systems. The maximum system voltage is 600 V, supporting serial or parallel wiring configurations. A five-year warranty is included with the product.

• 17.1 V voltage at maximum power (Vmp) and 5.9 A current at maximum power (Imp): defines the standard operating output for battery charging.
• 20.3 V open-circuit voltage (Voc) and 6.3 A short-circuit current (Isc): allows for electrical matching with solar charge controllers.
• Operating temperature range: -20 to +85 °C.
• Temperature coefficient of Voc: -0.33 %/°C; indicates voltage stability as operating temperatures rise.
• Temperature coefficient of Isc: 0.06 %/°C; indicates minimal current fluctuation during temperature changes.
• Power temperature coefficient: -0.39 %/°C; reflects overall power output stability across thermal environments.
• Power tolerance: 5%; defines the expected variance in the panel's rated energy production.
