This PowerVersity buying guide is a pick of the 5 best solar charge controllers. The best pick (EPEVER 60A MPPT Charge Controller) is discussed last. The guide starts with the 5th on top of the list.
This best solar charge controller picks highlights the most important features of each charge controller. The guide is written to make it easy for you to decide which of the items to buy.
To help you decide which of the charge controller to get, I strongly recommend that you take the time to read through the 5 charge controllers discussed.
Here are the 5 best solar charge controllers…
5Renogy Rover 60 Amp MPPT Solar Charge Controller
Beginning at no 5 in my pick of best solar charge controllers is “Renogy Rover 60 amp Solar Charge Controller”.
Renogy Rover 60 amp Solar Charge Controller has loads of features that will interest you. The first outstanding feature is its MPPT (Maximum Power Point Tracking) Technology. It converts high DC voltage from solar panels (or wind turbines) to the lower voltage needed to charge batteries. This charge controller also has a high tracking efficiency of up to 99% and a peak conversion efficiency of 98%.
This product also comes with intelligent protection against reverse polarity, overcharging, short-circuit, and reverse current. Its multiple LED indicators make it easy to read the charge status and all essential battery information.
There is one more feature I think is important to mention – its easy-to-use LCD (Liquid Crystal Display). This helps to monitor the system’s operation, and customize the charge controller parameters. The LCD also displays error codes – helpful to detect problems.
4Victron SmartSolar MPPT 100/50 Solar Charge Controller
At no 4 in my pick of best solar charge controllers is “Victron Smart Solar MPPT 100/50 Solar Charge Controller”.
This solar charge controller has a lot of great features. The first feature worth noting is its ability to pair with your mobile device or a PC. Pairing the charge controller with your mobile phone or a PC provides a convenient way to configure its parameters.
The charge controller also offers Advanced Maximum Power Point Detection. This ensures that the charge controller maximizes the power delivered by the charge controllers. It achieves this by continuously monitoring the voltage and current from your solar (PV) panels. The advantage of this is most noticeable when the sky is partially clouded, and sunlight intensity is constantly changing.
Furthermore, this charge controller comes with a battery preset feature. This feature allows you to set the battery type – you can accept factory defaults or enter your own preset values. The preset values will be used to optimally charge the batteries.
Additionally, you can preset the absorption voltage, absorption time, float voltage, equalization voltage, and temperature compensation settings.
3MidNite Solar Classic 150 Solar Charge Controller
Coming 3rd in my pick of best solar charge controllers is “MidNite Solar Classic 150 Solar Charge Controller”.
The first most amazing feature of this charge controller is its built-in ground fault protection. The benefit of this is that all components of the charge controller are grounded to the board. This makes it easy to ground the equipment properly.
The next noticeable and important feature of this product is its support for a variety of DC sources. This charge controller accepts DV voltage from solar panels, hydro, or wind turbines. This offers you more options for DC sources – particularly useful if you have access to other alternative energy sources.
The final feature that makes this charge controller unique is its support for a wide voltage range. The Classic 150 is designed to work with 12, 24, 36, 48, 60, and 72-volt batteries or banks. It also supports a charging current of up to 96 amps. These features offer you flexibility.
2Outback Flexmax 80 Solar Charge Controller
“Outback Flexmax 80 AMP Solar Charge Controller” is no 2 in my pick of best solar charge controllers.
This charge controller has some great features. First, is its cooling and intelligent thermal management feature. This feature allows it to operate at its full current rating of 80 Amps and ambient temperatures as high as 104°F (40°C). Without its intelligent thermal management feature, the system may have struggled to operate at such high amperage and temperatures.
Secondly, this charge controller supports a wide range of nominal battery voltages. This feature allows the charge controller to step-down a higher solar DC voltage to recharge a lower voltage battery without damaging the battery.
Finally, you can monitor Flexmax 80 charge controller remotely. With this feature, you do not need to visit the location of the charge controller to monitor, troubleshoot, or even reprogram it. This is very useful if you manage multiple sites.
1EPEVER 60A MPPT Charge Controller
Finally, on the 1st spot in my pick of the best solar charge controllers is “EPever 60a MPPT Charge Controller”.
The Epever 60a MPPT solar charge controller has an automatic system voltage recognition feature. It supports a voltage range of 12v to 48V. Moreover, the controller also comes packed with full safety protection features – including battery overvoltage, load overload, PV short circuit, reverse polarity, and more.
The charge controller also works with a variety of battery types – including gel, sealed, or flooded lithium battery types. It also supports multiple load control modes – including manual, lighting, and light timer. Moreover, the Epever solar charge controller has an advertised high tracking efficiency rating of no less than 99.5%.
Finally, The unit also comes equipped with a multi-function LCD display. This displays useful solar panel and battery information.
