On a 24 Volt System the performance difference is MUCH LARGER with the BOOST capability that others lack.  Many would output NEAR ZERO Power on a 24 volt system because the optimum panel voltage is BELOW the Battery voltage thus the need to BOOST to charge.
​
*  GLOBAL MPPT is important! -  When a panel has a shadow it creates MULTIPLE power peaks but only ONE is the  GLOBAL MPPT point. Not all controllers will find this and thus considerable energy goes unused.
Our controllers find it!

The 2 Peak Solar Curve shown here was applied to all Controllers in the test which models a panel that is 33% shaded.

​Get ALL of your Power!

In any solar power system the Charge Controller is the most important component.  Choosing a quality, USA made, MPPT Charge Controller such as ours can really make the system work for you by extracting every last bit of Solar Energy from the Solar Panels.  All of our controllers are MPPT and can get up to 2.16 times more power of competitor units with the same solar panel input.  Our 20 amp and 3.5 amp Buck Boost Controller's can extract power where other controllers are not able such as during heavy shading or low light conditions.

We only use high quality USA sourced components in our products and they are designed to last for decades.  Our Charge Controllers are fully automatic and work with Lithium Iron Phosphate and any Lead Acid variant like AGM, Flooded Deep Cycle, Gel Cell and others.   12 and 24 volt systems.
​
Simple to connect with only 2 wires in and out.  Larger systems are easily done by adding Solar Panels and additional Controllers - there is no limit.  Enjoy the best that solar has to offer with us.
