400W Off-Grid Monocrystalline Solar Panel Starter Kit with 45A PWM Solar Controller

Short Description

The Eco-Sources 400W solar panel starter kit is perfect for new customers wanting to get a start in the solar system. The Starter Kit is great for off-grid applications, such as RVs, trailers, boats, sheds, and cabins — providing many benefits, including, but not limited to, quiet power production and grid independence. Adding a polycrystalline or monocrystalline solar panel kit can extend your travels further than ever before.


1. Perfect solar panel kit for 12-volt battery charging or multiple panels can be wired in series for 24/48-volt battery charging or for grid-tied applications.
2. Ideal daily output: 2KWh (depending on the availability of sunlight). 25-year transferable power output warranty: 5-year/95% efficiency rate, 10-year/90% efficiency rate, 25-year/80% efficiency rate.
3. Easy to install with Z brackets for mounting and 1 pair 15 feet black & red extension solar cable for connecting solar panel to charge controller conveniently. Each solar panel comes with a pair of 35 inches cables with MC4 Male/Female connectors for quickly setting up.
4. Updated 45A PWM charge controller protects the system from over-charge, over-discharge, over-load, and reverse-connection.
5. Corrosion-resistant aluminum frame for extended outdoor use, allowing the panels to last for decades as well as withstand high winds (2400Pa) and snow loads (5400Pa).
