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 MPPT 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.

Build quality

Depending on where you will be using this controller, it is very important that you buy one with a weather proof build. Water proofing or at least a water resistant build is a must. Heat dissipating qualities are also a must, especially if you will be
using the controller in hot weather.

PC Monitoring enabled

To fine tune a charge controller, you are going to want to monitor its performance. While a good charge controller will let you monitor its performance using the on board LCD panel, you will get a lot of information if you can hook it up to a PC to analyze
in detail, using the convenience of a keyboard and mouse. Some chargers will come with a remote monitor as well, should you not have a PC but just want a second monitor that you can install in a more convenient location.

Multi-stage charging

You must look for charge controllers, especially the MPPT kind that only come with multi-stage charging. With multi-stage charging, the controller’s algorithm will smartly use either a safe, efficient, rapid or user-set charging protocol to charge batteries,
in the most efficient manner. So, now that you know what to look for in solar charge controllers reviews and product feature lists, let’s look at some of the most popular Amazon charge controllers that your money can buy today.

SolarEpic MPPT 40 A Solar Charge Controller with 150 V PV Input Capacity

  • Voltage = 12 V / 24 V
  • Battery Current = 40 A
  • Max Solar Input Voltage = 150 VDC
  • Heat Dissipation Method = Aluminum Heat Sink

This is a very popular charge controller that supports multiple charging options. You can use it with sealed, gel, flooded or user-defined batteries. It will protect your batteries against load shorts, over current and over charging. It will also protect
your batteries against over-temperature as well. It comes with a PC monitoring software and also a remote meter. But, you need to purchase the remote meter separately, as an optional purchase. Though this charge controller fares very well
in terms of performance, you will have to buy a remote monitor separately. This retails for about $190 but you can get it with the remote controller kit for about $235, meaning that you shell out about $40 for the monitoring LCD unit. But,
even at the increased price, there is fantastic value on offer. This product has some of the best MPPT charge controller reviews that you will find on the Internet. People love how it holds up in high temperatures in places like Alabama, during
the summer. Since solar energy is plentifully available in sunny areas, it is counterproductive to buy a solar charger that will not function well in heat. This particular model gives you no such problems.

Summary

So, there you have it. A quick summary of MPPT charge controller reviews of popular products that are currently selling on Amazon. Remember, you must first only choose
a charge controller that can comfortably handle your solar setup’s output voltage. That should be your first screening point. Only then will you be able to harness the maximum amount of voltage that you can step down to power up your batteries. Next,
look for amperage support and also the type of batteries that a charge controller will manage charging to. The MPPT charge controllers will support gel, sealed or any user-set batteries whereas the cheaper models will only support low capacity lead acid
batteries. Other factors that you must consider are the display, reporting and monitoring capabilities that a charge controller can provide. After all, you can optimize the charger based on the data it gives you in real time as well as through reports.
If you are going to be expanding your solar setup to power more and more devices in your home or commercial place of business, it is recommended that you choose a MPPT charge controller that you can continue to use, without the need for an upgrade in
the future.
