Best mid-range MPPT solar charge controllers up to 40A
In this article, we review six of the most popular, mid-level MPPT solar charge controllers commonly used for small scale solar power systems up to 2kW. These are more affordable, lower voltage (100-150V) units, which are generally designed for 12V or 24V battery systems, although several can be used on 48V batteries. A number of these charge controllers also feature inbuilt load control terminals for basic DC lighting and other loads.
In this review, we don’t list simple PWM controllers used for DC lighting and basic systems since there are many sites already covering these entry-level PWM controllers. For high-performance MPPT solar charge controllers with higher input voltages up to 300V and current ratings from 60A to 100A, see our high-power MPPT solar charge controllers review.
What is a solar charge controller?
A solar charge controller, also known as a solar regulator, is a battery charge regulator connected between the solar array and battery. Its job is to regulate the solar output to ensure the battery is charged correctly and not overcharged. DC coupled solar charge controllers been around for decades and are used in most small scale off-grid solar power systems.
Top 6 Solar Charge Controllers
Mid-level solar controllers up to 40A
Smaller capacity MPPT solar charge controllers with a current rating from 20A to 40A are used for many different applications including off-grid cabins and homes, RV’s, boats, caravans, telecommunications and remote site backup. These mid-range MPPT solar charge controllers are available from many different manufacturers, but this review will FOCUS on the most popular and best quality charge controllers from the most reputable manufacturers which have been on the market for several years.
| 1 | Victron SmartSolar MPPT | 35 A | 150V | 12V 24V 36V 48V | 350 to 480 | |
| 2 | EPever TRIRON Series | 40 A | 150V | 12V 24V | 150 to 250 | |
| 3 | Morningstar ProStar MPPT | 40 A | 120V | 12V 24V | 460 to 540 | |
| 4 | EPever XTRA Series | 40 A | 150V | 12V 24V 36V 48V | 130 to 190 | |
| 5 | Renogy Rover | 40 A | 100V | 12V 24V | 150 to 190 | |
| 6 | EPever BN Series | 40 A | 150V | 12V 24V | 170 to 250 |
Comparison Criteria
In this review, we rank the various charge controllers according to a number of important criteria including build quality, MPPT tracking speed, battery voltage range, operating temperature range (heat dissipation), monitoring, real-world performance and price. In our reviews, we generally rank performance and quality over affordability, so in this case, we rate the unit price lower than other criteria. This may come across as bias towards the more expensive models, but based on real-world results, testing and performance monitoring, the higher-end controllers have proven to out-perform the cheaper models.
