Features*Increased MPP charging current thanks to the use of modern microprocessor technology (efficiency, 95%). Additional benefits can be achieved in colder conditions.

*Customizable charging characteristics enable different types of batteries to be optimally charged. Stable charging voltage eliminates the risk of overcharging.

*The regulator has two charging connectors: for the main on-board battery and the starter battery (protection against possible overcharging).

*Maintenance-free charging mode provides protection against the risk of overcharging, overheating and other potential problems.

*Multi-tasking operation with various receivers and protection against excessive charging, which contributes to long-term maintenance of the battery in good condition.

*The 'IU1oU2' charging characteristic guarantees a safe battery charging process.

*Automatic compensation of voltage loss on the power cables and a filter that suppresses interference from the network.

*It is possible to monitor the photovoltaic system via the electroblock.

*Additionally, there is a connector for a battery temperature sensor, which allows for better adjustment of the charging voltage to the current battery temperature.

*It is recommended to connect 'Votronic Solar Displays' for full control over the functioning of the system .
