Product Information

The FOX320 is a dual battery solar charge controller for currents up to 20A, suitable for AGM, gel and lead acid batteries. Having the capability to charge two battery systems independently is ideal where there is a starter battery, for example, in addition to the main storage battery(ies).

12 / 24V devices can be connected up to a maximum current consumption of 20A; for inverters or higher current draw, you should connect directly to the battery bank. 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 (such as the lighting circuit) 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.

Ideal for the operation of an orientation light or small lights for the prevention of break-ins.

The optimised charge characteristic curve in combination with the hardware PWM control achieves a distinctly faster and gentler charging of the battery; hazardous gassing or overcharging are safely prevented. The FOX-320 can charge two battery systems and, as standard this is set to 90% of the power are to battery 1 and 10% to battery 2, although this can be adjusted.

On switching on, the controller recognises fully automatically whether a 12 V or 24 V battery system is connected. The active battery cut-out ensures the protection against reverse current and allows for an extremely low voltage drop between module and battery. The charge controller can be operated in parallel to other charging devices (such as alternators, generators, fuel cells).

The LEDs at the front of the controller give information on the charging state of the batteries, status of the consumer connection and whether a charge current is flowing from the modules or whether the battery is fully charged. The terminals B1(-), B2(-) and Output are directly connected with each other via the negative conductor, so it is important that both batteries are connected in the same way.

  • 12V/ 24V system voltage
  • 320 Watt solar power (640W at 24V)
  • for 2 battery systems
  • 20A overcharge protection
  • LED display
  • covert terminals
  • simple installation
  • connectors for 16mm² cable

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.
