45A 12/24V solar charge controller / regulator with LCD display and powerful dua

 

This 45A 12V / 24V solar charge controller offers advanced monitoring of the charging process and a wide selection of load programming features, whilst providing full protection for your battery bank. This user-friendly controller also boasts an LCD display and convenient dual USB output for fast charging of USB-compatible devices.

The controller uses PWM (Pulse Width Modulation) technology which has the ability to increase charge acceptance and extend the lifespan of the battery. PWM technology can also recover some lost battery capacity.

Full system protection:

This charge controller features a full range of electronic safety functions including protection against reverse current at night (from the battery back to the solar panel) and automatic cut-off to prevent over-charging, deep discharge, overheating, overload, short circuit and reverse polarity (of the solar panels and batteries).

Advanced programming and monitoring features:

This model features an LCD display with multilevel menu operation and a user-friendly interface with two multifunctional buttons. The screen displays information regarding real time solar panel and battery performance, including: voltage, current, battery state of charge, and battery temperature. An energy statistics counter also displays the accumulated daily and monthly charge values (useful for comparing solar panel performance between different periods).

An optional 12V load (e.g. 12V lighting / fans) may also be connected directly to the solar charge controller, with various settings for night time lighting applications.

In addition, this controller also offers various charging programs for different battery types, which can be easily selected by the user.

Rapid USB charging:

This solar charge controller also offers the rare and highly sought-after feature of a dual USB charging output. These 5V USB ports have a total combined output of 2.4A, offering fast and powerful charging of USB compatible devices such as mobile phones, tablets, mp3 players etc.

Additional features:

In addition to the inbuilt temperature sensor, the controller has a pair of terminals for connecting a remote temperature sensor (sold separately), which can be attached directly to the battery to obtain a more precise temperature measurement and optimise the charging process.

Compatibility:

This controller is suitable for solar panels with a combined power of up to 640W (12V batteries) / 1280W (24V batteries). The wide solar input voltage range of up to 50V ensures that even on-grid solar modules with a voltage higher than 12V / 24V can be used (please note that this controller is most efficient when the maximum solar panel voltage is just marginally higher than the battery voltage, e.g. 17V-18V solar panels will be best for charging 12V batteries).

This solar charge controller is designed for use with a sealed (default), gel or flooded battery / battery bank with a voltage of 12V or 24V. The controller will automatically determine the appropriate working mode.
