Description
    
The FOX-350 is a comfortable solar charge regulator for surface mounting. This FOX you can combine with any type of solar panel from any manufacturer.
This regulator takes care of your complete solar system and your batteries.
 
Overcharge Protection (series 100...)
 
A solar charge regulator has to control the battery voltage. In a 12 V battery system the voltage can vary between 10.0 V and 14.4 V depending of the actual state of charge of the battery, charge current, discharge current and the age of the battery.
 
When you have a normal full loaded battery and no charging or discharging current is flowing than the battery voltage is about 12.4 V to 12.6 V. At that moment when a charging current is flowing the voltage jumps to a higher level e.g. 13.6 V (depending of the current) - when a load is switched on the voltage drops down to a lower lever e.g. 12.0 or 11.8 V (also depending on the current).
 
When the solar panels produce energy the current is flowing into the battery and by the time the voltage level increase up to the range of 14.1 V. Now the overcharge protection has to starts the work.
 
When the level of 14.1 V is reached than the FOX reduce the charging current (by pulse wide modulation). Depending on the state of charge of the battery the current could be reduced from 100% to 0% continuously. The level of 14.1 V (step 2) is a good compromise for fast charging of the battery by a low gasing rate. When the voltage level is continuously 14.1 V for 40 minutes than the FOX reduce the maximum voltage down to 13.7 V (step 3). At this voltage there is no gasing at all. The charging voltage level will be 14.1 V again after the battery was a little bit discharged(voltage lower 12.4 V)
 
The first step of the FOX charging characteristic is the gasing charge situation. The reason for that is, the acid inside the battery must be well mixed to increase capacity and lifetime of the battery. While charging up to 14.5 V (step 1) inside the battery bubbles comes into being and mix the liquid while moving to the surface. The gasing charge program will run every 3 days and remains for 20 min.
 
Step 2 will run for 40 minutes and every time when the battery level falls lower than 12.4 V.
 
This charging program looks like a very complicate program - but this work does the microprocessor inside the FOX for you!
 
2 Battery-Charging (series FOX-300...)
 
The FOX-350 is designed also for charging two separate battery systems. Internal a two state relay switch the solar charging current between the two batteries - by that way the batteries are 100% electrical isolated. The relay is integrated into the "+" connection. The "-" pole of both batteries could be the same (e.g. car body). The load is every time connected to battery 1. See also the technical scheme on the other Web page.
 
The two battery switching logic we be only activated if both batteries are connected.
 
Note: When you install only 1 battery you must use the terminals for Battery 1! If you use Battery 2 Terminals the FOX-350 don't start it's work.
 
What is the logic of the FOX-350 for choosing the battery which will be charge?
 
Inside that logic we use the "Minimum Charging Level" (MCL), there exist a level called:
 
> MBL_OFF = 12.3 V and
> MBL_ON = 10.9 V
 
The MCL technology is integrated to protect battery 2 against a deep discharge situation.
 
What's happens now while charging:
 
Battery 1 will be charge so long that the charging logic reach step 3 and reduce the charging voltage to 13.8 V - in this situation the battery is 100% charged.
 
At the starting point of this logic the regulator select battery 1.
 
in general the voltage of battery 2 must below 13.8 volt to get selected.
 
The following cases are distinguished:
 
a) Voltage of battery 1 > 13,8 V: battery 2 is charged
 
b) Voltage of battery 1 > 13,2 V AND voltage battery 2 < 12,3 V: battery 2 is charged
 
c) Voltage of battery 1 > 12,3 V AND voltage battery 2 > 10,9 V: battery 2 is charged
 
d) Voltage of battery 1 between 10,9 V and 12,3 V AND voltage battery 2 < 10,9 V: battery 2 is charged (= emergency charging of battery 2)
 
In any other case battery 1 is selected. For minimum 15 min this selection will be used, after that period the logic test again the battery charge conditions.
Reverse-Current Protection (Serie 100...)
 
The discharge protection is made for small loads (consumers) for up to 12 A. Big loads like refrigerators, sine wave inverters ... you have to connect directly to battery.
 
After connecting the load to the regulator the battery is protected against to be discharged completely. A 12.0 V battery is empty when the voltage falls below 10.5 V. This value vary by the high of the load, this means when a strong pump or starter for the engine is running than the voltage could fall below that value - for a short time.
 
If the voltage falls below 10.8 V for a period of minimum 20 sec than the power of the load connector will be switch off for minimum 30 seconds. Than all loads which are connected directly to the battery are OFF. If the battery voltage increase again (in front of charging the battery or switching off the big loads) above 11.8 V for more than 20 seconds than the power for the loads will be switch ON again for a minimum time of 30 seconds. The delay of 30 seconds is integrated to protect the system against a swinging situation.
 
LCD-Display (Fox-350, FOX-350/E)
 
Das LCD-Display verfügt über 2 Zeilen à 20 Zeichen.
 
The LCD display is a two lines alphanumerically display with 20 characters in each line.
 
By the FOX-350 you could select 1 of five displays which will be shown on the display. You could select the display by pressing the rectangular bottom "Display". After you select a display and it's remain 15 minutes on the screen this display will be marked as default display.
 
When you are interested in other measured values which is shown on a different display you select this display by pressing "Display" and when you like to go back to your default display you press the round bottom "Esc".
 
The sign ">" indicates the battery which will be charged actually.
 
When the regulator switched of the load, because the battery gets to empty the display indicate also that state. The display toggles between your default display and:
 
"Battery 1 low" "load switched OFF".
 
When you toggle though the display mode you reach two select menus. These are for switching manually the load port and the selected battery.
 
When you change the selection manually it will remain for 15 minutes, after that time period the logic of the regulator takes over the control of that port again.
 
By pressing "Esc" you could refresh the display if necessary.
 
Deep Discharge Protection
 
The discharge protection is made for small loads (consumers) for up to 12 A. Big loads like refrigerators, sine wave inverters ... you have to connect directly to battery.
 
After connecting the load to the regulator the battery is protected against to be discharged completely. A 12.0 V battery is empty when the voltage falls below 10.5 V. This value vary by the high of the load, this means when a strong pump or starter for the engine is running than the voltage could fall below that value - for a short time.
 
If the voltage falls below 10.8 V for a period of minimum 20 sec than the power of the load connector will be switch off for minimum 30 seconds. Than all loads which are connected directly to the battery are OFF. If the battery voltage increase again (in front of charging the battery or switching off the big loads) above 11.8 V for more than 20 seconds than the power for the loads will be switch ON again for a minimum time of 30 seconds. The delay of 30 seconds is integrated to protect the system against a swinging situation.
