Best 60A+ MPPT Solar Charge Controllers

Best 60A to 100A MPPT Solar charge controllers review

In this article, we review the most powerful MPPT solar charge controllers used for large off-grid solar power systems and advanced backup power systems. These high-performance controllers from the leading manufacturers have input voltages ranging from 150V to 300V and output currents from 60A to 100A.

For smaller-scale systems which require smaller capacity solar charge controllers see our Best MPPT solar charge controllers up to 40A review

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 options, operating temperature range (heat dissipation), monitoring, real-world testing 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 this is generally correct according to real-world results and longer term testing and performance monitoring.

  • Build quality

  • MPP Tracking speed/accuracy

  • PV Voltage range

  • Monitoring/communications

  • Battery voltage options

  • Configuration options

Best Professional MPPT Solar Charge Controllers Full review

Here we compare the world’s most powerful MPPT solar charge controllers for professional off-grid solar and backup power systems. These higher voltage (Voc) controllers allow for larger solar arrays and longer strings using more powerful solar panels. As expected, the cost of these controllers is much higher than lower voltage entry-level models, with most units priced from $800 to $1500. Note prices can vary greatly depending on the country and local taxes.
