STECA SOLARIX 20A DUAL BATTERY SOLAR CHARGE CONTROLLER

PWM technology: this controller uses PWM (Pulse Width Modulation) technology which increases charge acceptance and prolongs the life of your batteries. PWM technology can also recover some lost battery capacity. The technology allows the controller to work not only with standard off-grid solar panels, but also with on-grid panels or solar panel arrays up to 60V (though it works at maximum efficiency with solar panels with an operating voltage of 17V-20V for 12V batteries, or 34V-40V for 24V batteries). The maximum allowed solar power input for this controller is 320W for a 12V system and 640W for a 24V system.
Dual battery capability: this is a perfect solar controller for a caravan, motorhome, boat or another system with 2 batteries (e.g. engine and leisure battery). The controller will charge the primary battery with 90% of available solar power, whilst the auxiliary battery will be charged with 10% of available power. When one of the batteries is fully charged, the controller will automatically divert all power to the other battery. The exact charging ratio can be adjusted with the use of a remote meter. Please note: This solar charge controller is also suitable for charging only one battery. The controller will automatically recognise this, and directly pass on 100% of the charging current to the single battery. A second battery may be added at any time.
Full system protection: this controller features one of the most extensive ranges of electronic protection functions currently available. These prevent reverse current at night (from the battery back to the solar panel), over charge, deep discharge, short circuit, and battery reverse polarity. Additional protection functions include open circuit protection, an automatic electronic fuse and self-diagnostic capability to highlight and resolve any system faults.

Option to directly connect a load output (up to 20A) with full over discharge protection for the batteries.
USB output (5V 1.5A) allows the possibility to charge any USB-compatible device (e.g. a mobile phone / tablet).
Multi-coloured LED indicators to facilitate clear monitoring of battery condition, charging status, load status and fault detection.
RJ-45 socket for a remote LCD meter to personalise default charging parameters.
Built-in temperature sensor allows charging adjustment depending on the ambient temperature.
