MPPT stands for maximum power point tracking. It is basically an algorithm that is built into a charge controller’s circuity to help increase the solar energy conversion efficiency by leaps and bounds. Solar panels produce electricity at a high voltage.
A high quality RENOGY 20 AMP MPPT SOLAR CHARGE CONTROLLER will efficiently knock down that voltage to efficiency charge batteries that need much less voltage. Without a MPPT controller in between, batteries will still charge but not nearly as efficiently when a MPPT charge controller
is used. A non-MPPT charge controller will offer the safety features that a MPPT charge controller does, but without the improvements in charging efficiency. It goes without saying that MPPT charge controller reviews will often discuss the value that
a MPPT charge controller can offer, since they often sell well in excess of $100.
High Max Input Voltage
Some of the best MPPT charge controllers will feature a max input voltage of 150 V at 40 A. These usually cost close to $200. At about $100, you will get an MPPT charge controller with a max input of 75 Volts at 15 Amps. Therefore, you must buy one with
a max input capacity that is well in excess of what your solar panels can produce, so you can make the most of solar energy that is available to you.
LCD Display + Ease of Use
A very sophisticated charge controller with a very high input voltage can still be pretty useless if it doesn’t have a good screen and ease of use. The user interface or navigation to set up the controller should be very good. If you look through some
solar charge controllers reviews, you will see a lot of rants about how difficult charge controllers were to program and use. Of course, a lot of those reviewers also say that they do work very well after the initial set-up hiccups are sorted out. But,
as a thumb rule, you must avoid charge controllers that are difficult to program and use.
Renogy Rover 20 Amp 12V/24V DC Input
Voltage = 12 V / 24 V
Battery Current = 20 A (Also available in 40 A Mode)
Max PV Input Short Current = 25 A
Max Battery Voltage = 32 V
Max Solar Input Voltage = 100 VDC
Tracking Efficiency = 99%
Peak Conversion Efficiency = 98%
Heat Dissipation Method = Die-Cast Aluminum Design
Available in MPPT 20 A and MPPT 40 A models, the Renogy Rover Series is an incredibly popular line of charge controllers. It prevents both over charging and over discharging. This Rover model will ensure that your battery’s life is extended very well,
with the accompanying improvements in charging efficiency. The algorithm can use a 4-stage charging process for rapid, safe, user-set or efficient charging. The LCD screen is programmable to display parameters that you are interested in, with
ability to store and display data for up to a year.

One aspect of all business procedures that will probably never change is the delivery of physical goods. This business in itself only used to be a luxury of the wealthy. But the internet has made it financially accessible, more competitive and more lucrative for the middle class.
Consider the $5.02 billion that was made by different shipping and delivery services from Amazon in 2015 alone. This shows the enormous opportunity that exists in the shipping industry.
Whether you are freight forwarding, drop shipping or using any other method by land, air or sea, the prerequisites, for the most part, remain the same across the board.
If shipping is your thing, then the few tips below will certainly help you get your shipping business set up.

My transition from employee to business owner has turned out very well, but the path wasn't always so clear. While working toward my law degree, I clocked time as a legal intern. I quickly discerned I wasn’t quite cut out for the 9-to-5 lifestyle. It meant getting up early, rushing my prayers and rituals, and making a 9 a.m. court start every day. To put it mildly, it was a horror.
I began my first foray into entrepreneurship during this period. It led to an epic failure and a whole lot of debt. I got out of my depression after reading the story of Urbanladder, a furniture company started by Ashish Goel and Rajiv Srivatsa. The two had found themselves in a situation similar to mine and were dissatisfied with their jobs -- one at McKinsey & Company and the other at Yahoo.
It was only much later that I was able to define the actions that would make my leap of faith a success. I share them here in the hopes they can help others who are looking for more meaning in their career.

In a tech startup you can reach a point where your efforts bring diminishing returns. For all the hard work you put in, your customers just won’t bite. That leads to a death spiral, which is worse than failure.
You can jinx your startup in a thousand different ways. But the following three lie at the core of many others.
