This video shows how to use the Helios Portable Solar Power System.
The Helios is a super advanced 2800w portable solar power generator system that allows you to own your own mini power grid anywhere in the world!
Visit our website @ www.PortableSolarPower.Biz for more info.
now we know how much load we will have on a typical day being drawn from our solar batteries its time to determine how large of a battery bank we need. the loads are measured in watts while the batteries are measured in amp hours. once you determine if you will go with a 12v or 24v or even a 48v battery bank system its time to figure out how many amps you will need.
match the watts use in a day with the watts in your solar panels however you must consider storms, seasons, bad solar days so having more solar is good.
