The Anker Brand makes a high-quality Solar Generator with the longest Warranty of any brand. Their systems use a high-end LiFePO4 battery and their systems have a 5-year warranty with a 10-year lifespan expected with everyday use. The most popular and largest model is the Anker 767 with 2400 Watts of power and 2048 watts hours of battery backup power. This is plenty of power to take camping and to handle the basics in a power outage like your refrigerator lights and more.
Important Anker Solar Panel Note: The Anker 767 uses XT60 connections on the solar cables exclusively. The solar panels do not connect to a Standard MC4 Solar Connection cable. Click this link for a 10FT XT60 to XT60 Solar Extension cable
