Votronic Solar Charge Controller SR 230 Duo Dig. - 1616

Votronic SR 230 Duo Dig Charge Controller up to 230W

Effective battery charging for motorhomes, caravans, boats and self-sufficient solar systems! VOTRONIC solar regulators connect the solar module and battery, operate fully automatically, and ensure optimal battery charging without overcharging.

Special features at a glance:

• Main charging output I: Automatic charging of the leisure battery
• Auxiliary charging output II: Recharging and trickle charging of the starter battery
• Overcharge protection
• Gassing control
• Reverse current blocking
• On-board power supply filter
• Integrated temperature compensation
• For 12V applications
• Reverse polarity protection
• Suitable for all battery types

A solar system, correctly dimensioned, makes a motorhome, caravan or boat self-sufficient and consists of three components: solar module, solar charge controller and battery.

During the day, power consumption is immediately recharged, preventing battery discharge at night. The devices are characterized by high operational reliability. High-quality charging technology combined with intelligent microprocessor control ensures precise adherence to charging voltages, currents and times. The main charging output with IU1oU2 charging characteristic can be optimally adjusted for acid/wet batteries, gel or AGM/fleece batteries.
With the temperature sensor (recommended accessory) for battery temperature compensation, the charging voltage is automatically increased at low temperatures (winter operation), and the weakened battery is charged better and faster. At summer temperatures, the charging voltage is reduced, thereby reducing the load (gassing) on the battery and increasing the lifespan of gas-tight (e.g. gel) batteries. The second charging output has reduced voltage and current and serves to support charge and trickle charge the vehicle's starter battery during long periods of inactivity.

Note: The classic functionality of PWM regulators is becoming less compatible with the sensitive battery management systems of modern LiFePO4 batteries. Therefore, this characteristic curve is omitted in the new SR charge controllers, and we strongly recommend using MPP regulators for charging lithium batteries.
