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 energy. With a maximum charging power of 440 watts and the proven maximum power point tracking (mpp) technology, the charge controller maximizes the yield of your Solaranlage by automatically determining the optimum operating point for the solar cells. This ensures efficient conversion of solar energy into electrical power and thus optimizes charging efficiency.

Two battery charging outputs

The Votronic 1730 mpp 440 ci solar charge controller has two battery charge outputs that enable automatic charging of the main supply battery (12v), as well as backup charging and charge retention (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 controller ensures the prevention of harmful acid stratification in lead batteries through a defined charging voltage increase (u1) and ensures an equalization charge of the individual battery cells (lead and lithium), followed by an automatic trickle charge (U2)

AES" switching output

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