Features:

In order to have a cost efficient and simple charge controller, this device was developed

Up to 15 Amperes Charging Power using POWER-MOFET-Transistors.

Overcharging-Protection of the Battery by fast Pulse-Wide-Modulation. This Mode gives better charging-results than slow Pulse-charging.

Boost-charging from time to time (depending from the discharging level or at least once a month).  Boost-charging avoids the degeneration of Liquid-Batterys.

80 % of the Batterys die from a degeneration of the Battery-Plates. Due to research-work of the University of Vienna, Austria and NASA,USA this degeneration can be reduced drastically by very short High Current Pulses to the Battery. This charge controller is equipped with this feature, to extend life-time of the Battery.

Deep-Discharge-Protection with up to three Outputs with max 3 x 10 Amperes. One MOSFET-Output and two Relay-Outputs can be used.

The Outputs can be programmed to be switched on only for a dedicated time (three hours in the evening for example). This is interesting in areas where the capacity of the Batterys is reduced.

The two Relay can also be switched on by a Manual Switch. They provide max. 10A, 220V.

Applicable for all Types of Lead- Batterys (Gel-Type etc.)

Applicable for 12V or 24V-Systems. The System-Voltage is verified automatically. If you use the Relays, you have to order a 12V or 24V-Version.

Additional Inputs for charging of the Lead-acid Batterys with a 230 V / 12V or 24V Transformer

Many Safety Precautions like:
- High Temperature-Protection
- Reverse-Connection Protection for the Solar-Panels and Battery
- Automatic Short-circuit Protection for the Load, no more replacement of Fuses are necessary
- Over-voltage Protection for the Input of the Solar-Panels
- Protection for "no-Battery"-connection (if only Solar-Panels are connected, the voltage will raise very    high)
- No Reverse-Current to the Panels at night

One Major Problem of Solar-Systems is the stealing of the Panels. This is a very serious Point for Solar-Systems. This Charge-Controller has a Multistage theft-protection.

With a Moving-detector: A Loud Alarm can be generated if somebody is coming close to the Solar-System
With an external Circuit: A high voltage is activated at the Panels-Frame as soon as somebody is coming close to the Panels. If somebody touches the Solar-Panels, he gets a electrical shock. Of course the voltage can not hurt anybody.
Optional the Alarm can generate a Telephone-notification to a Mobil phone

Integrated Charging-Unit for rechargeable NiCd, NimH -Batterys (2 x Type AAA and / or Type AA), which can be used for Radios, Torches etc. 12V chargers for this application are very rare!

Optional: One short-circuit-protected Voltage Output with a fixed voltage of 5 V or any other if needed. For to connect small Radios or TV directly to the Unit.

Three LED's for to Display Battery empty, Solar charging and NiCd/NimH-Charging

By a Program-Switch some functions like Battery-Type etc. can be programmed. You can also activate a Simulation-Mode for the Battery-Voltage.

For Data-Logging a PC or Notebook can be connected (via serial cable or USB with Adapter). The Battery-Voltage can be logged and evaluated (By Excel for example)

Easy update of new Software by a small Program and the Data-Cable.

Optional you can order a Programming-Adapter and Compiler. Thus you can make your own Program-changes and you can even load other Software for using this Unit for another purpose (for a Irrigation-System for example or for a Alarm-System etc.)..
