Sphere MPPT 12V/24V 20A Solar Charge Controller. MPPT20A

The Sphere MPPT 12V/24V 20A Solar Charge Controller is the ultimate solution for optimal solar energy conversion. Its innovative MPPT technology allows for rapid tracking and capture of the maximum power point of multi wave peaks, resulting in an impressive 94% energy conversion efficiency - higher than 75% of PWM solar controllers.

Safety is a top priority, so this controller is packed with protections such as reverse polarity, over-charge/discharge, over-load/temperature, back feeding (night), and short circuit protection. The controller also features a cover that protects terminals against corrosion and shorting.

Constructed with tough ABS housing and upgraded aluminium heat sinks, this durable unit is built to last. It's a great addition to any solar panel system, and is compatible with a variety of lead acid deep cycle batteries and LiFePO4 batteries, thanks to its multi-stage properties that better support batteries.
