This 20A 12V/24V solar charge controller has been designed and produced in Italy by one of the leading European solar technology manufacturers, in accordance with the highest quality standards.

This solar charge controller uses PWM (Pulse Width Modulation) technology to improve charge acceptance and extend the life of your battery. PWM technology can also recover some lost battery capacity.

Key features:

Complete electronic protection of your battery and system, e.g. prevention of: current back-flow, overcharge / discharge, overvoltage, overload, short circuit, and reverse polarity 
LCD display showing advanced system information, including: power, voltage and current for the solar panels and battery, energy counter, temperature, load work 
Pre-set programmes for several battery types (sealed, AGM, gel, flooded lead acid) and fully adjustable low-voltage battery protection 
100% designed and made in Italy to the highest quality standards, with a 5 year manufacturer warranty


This unit is compatible with sealed, gel and flooded lead acid batteries. It has pre-set charging programmes for different battery types, and battery low voltage protection can be also configured according to your requirements. Load working modes can be programmed for many different applications; for example to set on/off timers for lighting/ fans/pumps. 

This controller is compatible with solar panels with a combined power of up to 320W (12V battery) / 640W (24V battery) and voltage of up to 55V, although this controller works most efficiently with solar panels with an operating voltage of 17V-20V (with a 12V battery) / 34V-40V (with a 24V battery).
