Best MPPT Solar Charge Controller by Input Current Rating
Top 10A MPPT Solar Charge Controllers
EPEVER 10a MPPT Charge Controller with LCD Display, 100V Max Input, 12V/24V...
The manufacturers of our first 40A MPPT solar charge controller– SolarEpic, have a reputation that precedes them. And this product certainly doesn’t disappoint. It features protections for over temperature and over charging – and with supporting PC monitoring software and remote meter provides advanced maximum power point tracking which optimizes the solar systems functionality.
Additionally, the solar charge controller has a negative ground charge with maximum point of 150V PV input – it supports various charging options including sealed, user-defined, gel and flooded specifications. Frankly, it doesn’t get any better than a solar charge controller that is somewhat versatile.
Pros Has improved algorithms and remote temp. sensing from older models Similarly, it features a metal case that aids heat dissipation Great LCD display control panel Reasonably priced.
Cons Occasionally sends small voltage spikes through the system
ECO-WORTHY BEST MPPT Solar Charge Controller (20A)
In a world full of fly-by-night Chinese made solar charge controllers, one of the few companies you can be sure will deliver on their promise to provide the best solar charge controller. The Ecoworthy 20A is not only the product of a reputable company, it has a variety and features and mode that gurantee user satisfaction including its five output modes – manual, standard, timer, light sensor and light sensor (on + timer off).

Pros Features interactive LCD display Easy set up and installation Also it has 5 available modes and options for specific battery types
The Renogy 20Amp MPPT solar charge controller is credited with an additional feat not common to other units – it can reduce the number of solar panels needed by up to 30% by leveraging the system to perform better. Furthermore, the MPPT charge controller can match the changing voltages caused by the state of charge of the batter which results in 30% more efficient transfer of power.
With full power output in ambient temperature and a 4-stage charge feature, this MPPT can be used for sealed, gel and flooded battery. It features negative grounding, and peak conversion efficiency of 97%.
Pros More elaborate than the standard PWM solar power controller Installation is a breeze Also, It can reduce the number of solar panels needed by up to 30% by improving system performance
The Victron BlueSolar MMPT 75/15 will do an exceptional job of controlling up to 200 watts of solar panels – or even 400 watt at 24 volts. It comes equipped with a variety of features that aid exceptional performance including a multi-stage algorithm that is good for most flooded and AGM batteries. It also allows has customizable settings that can be programmed to suit specific need, and its electronic components are resin encapsulated to protect against the elements, and additionally its set up can also be done conveniently on your device – say a smart phone and ultimately the BlueSolar MPPT 75/15 can be configured to operate at full potential without a display, so the panel is strictly optional.
Pros Excellent electric production It also has Very simple installation It has an available bluetooth adapter for reporting on a smart phone
Cons Price is a little steep (compared to other solar charge controllers with the same capacity)
Looking to find a low price but high quality 40A charge controller? Well, the EpEver 40A MPPT solar charge controller just might be the cheapest, but most reliable unit on the market. Compared to other models and units, the EpEver is fairly new – however, new often translates to upscale technology that is often not included in other brands. It features a multi-function LCD that displays system information. In addition, the solar charge controller is accompanied with a MT50 remote meter that shows so much more and allows control more features. The remote meter is easy to use and controls everything I need. Furthermore, with an automatic system voltage recognition (12/24 V) auto-saving function and two voltage disconnect levels plus high tracking efficiency no less than 99.5% .
Pros Ultra-fast tracking speed Also, it is capable of accurately recognizing and tracking of multiple power point Furthermore, it is User programmable for battery types, load control etc. Finnally Common positive grounding design
