Ecoflow 400W Rigid Solar Panel with 4x Mounting Feet - ZPTSP300
Fast Charging
With a high conversion efficiency rate of up to 23%, the 400W panel charges your LFP batteries faster than similar-sized solar panels.
Weatherproof & Durable
The rigid panel balances design with robust materials allowing the panel to weather any storm while offering the same excellent performance and aesthetics for years.
Off & On-grid Solution
This high-wattage panel works for both on-grid and off-grid solar-powered setups, storing energy for outages, reducing power bills, or powering an off-grid home.
Universally Compatible
The 400W solar panel includes a 300mm charging cable that gives you plenty of space, maximizing solar input. With an all-inclusive solar connector, the 400W rigid panel works with other 3rd party solar system, power stations and comes with 10 Years Warranty.
High Solar Energy Conversion
Made from highly efficient monocrystalline cells, the 400W rigid solar panel has an excellent efficiency rating of 23%, allowing you to charge faster than using similar-sized panels. Combine this panel as part of your existing PV system or Power Kits setup, and allow the integrated MPPT algorithm to optimize your solar input.
Waterproof & Durable
The 400W rigid solar panel is designed for the outdoors. With an IP68* waterproof rating and a robust anti-corrosive aluminum frame, the panel can withstand a wind speed of up to 130mph* and a significant snow load of up to 113lb* and continue to capture solar energy for years to come.
*Water and dust resistance were tested under controlled laboratory conditions with a rating of IP68 under IEC standard 60529 (maximum water depth of 1 meter for up to 72 hours.)
*Well-mounted solar panels can withstand a dynamic 2400pa wind pressure load (130mph wind speed) and a static 5400pa snow load (113lb per sq foot of snow).
Off-grid & On-grid Solution
This high-wattage panel works for both on-grid and off-grid solar-powered setups, storing energy for outages, reducing power bills, or powering an off-grid home
Universally Compatible
EcoFlow solar panels use an all-inclusive solar connector, so you can even use them with your existing 48V power system. The 400W solar panel includes a 300mm charging cable that gives you plenty of space to mount multiple panels, maximizing solar input.
