20A 12v Photonic Universe dual battery solar charge controller (DM Series)

Dual battery solar charge controller (DM Series). This advanced 20A 12volt dual battery solar controller uses advanced MPPT technology to charge two independent batteries or battery banks. 

The main battery is charged at high power, while a secondary battery is given a trickle charge of up to 1A. This makes it a perfect solar controller for a campervan, motorhome, boat or any other system with 2 batteries (e.g. engine and leisure battery). 

The main battery will be charged with a majority of the power, whilst the second battery will be trickle charged to keep it topped up and ready for use. 

Maximum Power Point Tracking (MPPT) Technology MPPT technology ensures the maximum efficiency of your solar system and significantly outperforms standard PWM solar controllers. Another benefit of MPPT technology is the wide solar input voltage range - this controller can work not only with standard off-grid 12/24V solar panels, but also with multiple panels with voltage up to 100V. The maximum combined solar input power allowed for this controller is 260W for a 12V battery system or 520W for a 24V system. 

Full Range of Protection Functions: This charge controller features a comprehensive set of electronic protection functions to prevent reverse current at night (from the battery back to the solar panel), over-charging, short circuit, reverse polarity and more. The solar controller case is water resistant to a rating of IP33 when installed, for protection against sprays of water at up to 60 degrees from vertical. Advanced Battery Compatibility: this model is 100% compatible with a broad range of battery types for the main battery, such as Gel, AGM, Lead-Acid Flooded,  and Lithium ( LiFePO4 or Li-NiCoMn ) batteries. 

Current limiting function (20A) allows the possibility of adding more solar panels to your solar system in the future
