Votronic MPPT Solar Charge Controller 360 CI 1723

Votronic solar controller MPPT 360 CI 1723 – up to 360 Wp for efficient charging in the vehicle

The Votronic solar controller MPPT 360 CI 1723 is the current generation of CI bus MPPT charge controllers and the official successor to the previous version. It connects your solar modules to the leisure battery and ensures that you convert solar power into charging current as effectively as possible – ideal for motorhomes, caravans, boats or self-sufficient 12 V solar systems with up to 360 Wp.

MPPT technology: more yield from the solar module, especially in changing conditions

The controller works with Maximum Power Point Tracking (MPPT). The optimum operating point of the solar modules is continuously tracked so that the available solar yield can be used as well as possible. Excess module voltage is “converted” into additional charging current for the battery by highly efficient switching regulator technology – in practice, this gives you shorter charging times and better use of your solar system.

CI bus connection: display data centrally and keep an eye on solar output

Via the CI bus connection, relevant values can be conveniently transferred to central vehicle panels or displays. In addition, there is a measuring output for EBL for using existing solar current displays in the electrical block to check the system.

Suitable for many battery types: 8 charging characteristics incl. LiFePO4

To ensure the controller suits your system, 8 switchable charging characteristics for lead, gel, AGM and LiFePO4 are available. The “IU1oU2” charging characteristic provides defined charge control including float charging and supports battery- and cell-friendly charging.

Two charging outputs: charge the leisure battery and support the starter battery

The MPPT 360 CI charges the main leisure battery (12 V) and also offers a second output for support/maintenance charging of the starter battery (with overcharge protection). This is particularly practical if your vehicle is parked for a long time or many consumers are running on the leisure battery.

Practical additional functions for vehicle use

• AES switching output: Can automatically switch fridges with AES from gas to 12 V operation when there is sustained surplus solar power
• Parallel/buffer operation: Charging specifications are maintained even with consumers active at the same time
• Overcharge protection: Reduces the charging current when the battery is full and solar output is high, and automatically recharges when power is used
• On-board system filter: Supports trouble-free parallel operation with alternator, mains charger, generators etc.
• Temperature sensor connection: A temperature sensor is mandatory when the lithium characteristic is set
