Sophisticated solar controllers of the newest generation

The MPPTplus+ Solar Controller series consists from highly sophisticated solar controllers of the newest generation. Thanks to the microprocessor-controlled charging and MPPT regulation they are suitable for all common module technologies.

By virtue of the MPPT function (Maximum Power Point Tracker) it always makes the most efficient use of the solar power provided by the solar modules. The high efficiency grade (max. 97 %) and the significantly shorter battery charging time allow for the best possible power exploitation in your solar system.

Recommendation for application
MPPTplus+ Solar Controllers are perfectly suitable for solar systems in which the panel voltage is significantly higher than the battery voltage. With the use of an MPPTplus? Solar Controller 30 % of the solar panel surface can be saved in order to achieve a comparable power exploitation as with common solar chargers.

Specifically in northern latitudes, where despite solar radiation the temperature of the solar panels remains low, the MPPTplus+Solar Controllers make the most out of your solar system’s power.

MPPT technology System voltage 12 V/24 V DC Optionally remote-controlled Switchable load output 12 V/24 V DC Suitable batteries: lead-acid, lead-gel, AGM and LiFeP04 CE 3 years warranty Made in Europe

Important characteristics and features

MPPT charging characteristic – highly efficient, fast, battery-preserving

+
Maximum Power Point Tracker (MPPT)
The most efficient working point of the solar module (MPP) changes depending on various factors such as, temperature, radiation power and the type of the solar cells. The technology hidden behind the MPPT regulation continuously determines and uses the maximum power exploitation of the solar modules. At this, the voltage surplus from the solar modules is converted into a higher charging current. This higher charging current assures a shorter battery charging time.

Automatic recognition of the system voltage

+
The MPPTplus+ Solar Controllers are suitable for operation in 12 V and 24 V solar systems. They recognize independently whether a 12 V or a 24 V system is connected. The system voltage can be selected manually by means of the DIP switch.

Selectable battery type by DIP switch

+
The solar controllers are perfectly adapted to charge all types of lead batteries (acid, gel, AGM) and LiFePO4 batteries. An optimum tuning of the charging characteristics to the different battery types is made possible by the DIP switch.

Automatic temperature compensation

+
During the charging process the temperature is measured by the external temperature sensor and this allows the dynamic adjustment of the cut-off voltage to the given temperature conditions. At high temperatures the cut-off voltage will be reduced. Overcharging and unnecessary gassing is prevented. At low temperatures the cut-off voltage will be increased, the battery can be recharged optimally.

Energy saving – switchable standby function

+
The standby function can be activated respectively deactivated by using the DIP switch. In the case of insufficient solar voltage the solar controller enters the standby mode (if activated). Thus, the internal current consumption of the MPPTplus+ controller is reduced by up to 80 %, the connected battery preserved and unnecessary discharging prevented. As soon as sufficient voltage is applied the solar controller automatically returns from the standby mode.

Switchable load output

+
Solar controllers of the MPPTplus+ series also have a switchable load output as standard. This can be switched on and off manually using a push button.

Multi-step charging technology – Adapted to each battery type

+
The charging mode is perfectly adapted to the selected battery type.
Depending of the battery type charging is done in a two- respectively in a three-step process.

Equalization charging for optimum battery maintenance

+
For the professional battery maintenance of lead batteries the MPPTplus? Solar Controller offers the additional function “Equalization charging”. It may be activated via DIP switch. In this mode charging is done with increased cut-off voltage for 60 minutes. Existing sulfate layers inside the battery will be removed and the duty cycle of the battery significantly increased.
Advantages of an equalization charge
Well-maintained wet respectively acid batteries have a significantly longer duty cycle. In the case of longer storage periods without current withdrawal or in the case of deep-discharged batteries we recommend the employment of the “Equalization charging” in order to remove existing, harmful sulfate layers as soon as possible and completely.

Monitoring and controlling the power supply professionally

+
The Solar Controllers of the MPPTplus+ series are optimally adapted to fit the IVT inverters of the DSW series.

With the help of the original IVT accessories – Remote Control Touchscreen FB-04 (cable-connected version) or the Webbox LCD (computer network) – up to 4 devices (DSW inverter and MPPTplus+ solar controller) can be individually controlled and monitored.

Monitoring and controlling the power supply professionally

Individual configuration and evaluation of the MPPTplus+ solar controller
By means of the Remote Control or the Webbox LCD, you can set the end-of-charge voltage, the deep discharge protection and the temperature compensation as well as evaluate and monitor the solar power. The charge current can be limited, which is especially important when charging smaller batteries. In addition, the operating times of the load output can be programmed.

Extensive protective functions

+
All relevant protective function such as, overcharging, deep discharge protection and overheating protection are controlled fully automatic via microprocessor.

Overcharging protection
As soon as the cut-off voltage is reached, the charging current is shut off by the solar controller. Thus overcharging and damage to the solar battery is prevented.

Deep discharge protection with automatic load shut-off and reactivation
The deep discharge protection causes the automatic shut-off of the load output by the solar controller in the case the battery voltage falls below the minimum voltage. With this, the deep discharging of the battery is prevented.
As soon as the battery is recharged and the battery voltage is above the reset voltage the solar controller automatically reconnects the load output.

Overheating protection
The MPPTplus? Solar Controllers are protected against overheating. A built-in temperature sensor assures that the charge controller shuts off automatically in the case of excessive overheating (> 85 °C). As soon as the controller has cooled down it turns back on automatically.

Protection against short circuit and reverse polarity
The controllers are protected against short circuit as well as against reverse polarity with a
10 A, 20 A or 30 A flat fuse, depending on the model.

Non-return valve
All IVT solar controllers are standardly fitted with a non-return valve.
In the case of too low solar power for example, at dusk or at night, the non-return valve prevents the discharging of the battery via solar module.
