The FOX-320 / FOX-220 solar charge regulators are for charging currents up to 22 A, suitable for AGM, GEL and lead-acid batteries. With the FOX-320 two different battery systems can be charged. The optimized charging characteristic, in combination with the hardware PWM control, results in a considerably faster and more gentle charging of the battery. Hazardous gassing and/or overcharging are safely prevented.
The deep discharge protection is designed for consumers up to a maximum current consumption of 20A.
The FOX-MD1 is a remote display for the FOX-220 and FOX-320 and is simply connected with the prefabricated cable. The data measured by the FOX devices can be read comfortably in the 2-line display with large characters. In addition to pure text outputs, bar charts are also available for the charge status of the batteries.

Automatic 12V / 24V detection
The controller automatically detects the system voltage. The active back-current blocking device ensures reverse current protection and allows an extremely low voltage drop between the module and the battery.
Der Regler erkennt die Systemspannung vollautomatisch.
Extensions
The Multi Display FOX-MD1 can at any time be connected to the FOX-220 by simple plug-in. This allows the current voltages and flows to be displayed, even graphically. The programming function of the FOX-MD1 enables you to change and save various parameters.
Status Informations
The LEDs at the front of the controller give information on the charging state of the battery, status of the consumer connection and whether a charge current is flowing from the modules or whether the battery is fully charged.
Discharge Protection
The adaptive total discharge protection monitors and protects the battery against damaging total discharge, and alternatively the nightlight function can be used. When using the nightlight function, a consumer will be switched on during the time the modules do not supply charge current (i.e. when it is dark). Ideal for the operation of an orientation light or small lights for the prevention of break-ins.

For 2 Batterie Systems
The FOX-320 allows loading of two independant battery systems. By factory defaults 90% of the energy will go into battery 1 and 10% of the energy into battery 2. A load (consumer) connected to the terminals L+/L- will always be powered by the battery 1. Battery 2 is typically the starting battery or a battery backup.

FAQ's
In the manual of the FOX-320, it is specified that the negative poles of the two batteries should be connected. Why is it so? Are they not directly inter-connected within the charge controller? Do they really need to be also directly connected?
Thanks in advance for your answer.
Like written in the manual you have to connect the battery minus poles directly at the battery with thick 12sqmm or thicker cables.
If you don't do that a hight current could flow over the PCB board in the inside of the regulator - much more than the specified 20A.

Serie X-20: LED-Infos
Describes the function of the charge controller and the significance of the LEDs. Time-lapse, the various states during the charging and discharging of the battery and the information shown the LEDs explained.
The FOX-MD1 is simply connected with the prefabricated cable. A connection cable with 5m length is included with the product. The maximum cable length is 10m.
Display
Thanks to the large display with backlight, the data can be easily read even in dark environments. After 10 sec. with no button press, the backlighting will automatically switch off again to save energy. The contrast of the display can be adjusted via the menu. The large 2-line display with 20 characters shows actual alues of the charging current (Ic), current generated by the panel (Is), discharge current (Il) and battery voltages. An arrow indicator in the display shows which battery actually be charged.
The status of the batteries voltages could also be shown with bar graphs.
The FOX-MD1 can be used to set parameters, function, settings in the connected FOX device. Depending on the connected device: e.g. the battery type (AGM, gel, lead acid), charging ratio B1 to B2.
Mounting
The FOX-MD1 can be used as built-in or surface mounted unit. Therefore, a mounting frame is included with every FOX-MD1. A cable with 5m length is inside the package. The maximum cable length is 10m.
