Best Solar Charge Controllers Reviews

MPPT Feature

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.

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.
