Votronic 1730 MPP 440 CI solar charge controller

The MPP 440 CI solar charge controller from Votronic (MPN 1730) is a state-of-the-art solution for efficiently charging your batteries with solar energy. This innovative charger has been specially developed for use in motorhomes, boats, and other vehicles to ensure that you always have sufficient power. With a maximum charging power of 440 watts and proven Maximum Power Point Tracking (MPP) technology, the charge controller maximizes the yield of your solar system by automatically determining the optimal operating point for the solar cells. This ensures efficient conversion of solar energy into electrical power, thereby optimizing charging efficiency.

Two battery charging outputs

The Votronic 1730 MPP 440 CI solar charge controller has two battery charging outputs that enable automatic charging of the main supply battery (12V), as well as trickle charging and charge maintenance (max. 1 A) for the vehicle starter battery (Start) with built-in overcharge protection.

IU1oU2 charging characteristic

The "IU1oU2" charging characteristic of the Votronic MPP 440 CI solar charge controllera defined increase in charging voltage (U1) prevents harmful acid stratification in lead batteries and ensures equalization charging of the individual battery cells (lead and lithium), followed by automatic maintenance charging (U2)

Switching output "AES"

The "AES" switching output enables automatic switching of refrigerators with "AES" (Automatic Energy Selector, Electrolux/Dometic) from gas to 12 V operation in the event of a sustained solar power surplus.
