Save in the right places with Steca Tarom MPPT

With its innovative functions, the Steca Tarom MPPT not only offers greater efficiency, flexibility and comfort but also helps to avoid certain unnecessary costs that are incurred during the planning, implementation and ongoing operation of PV systems.

No need for additional devices!

... due to added flexibility as a result of the wide input voltage range
The Steca Tarom MPPT can be used with a wide input voltage range, which allows greater flexibility when selecting modules. The entire input voltage range of up to 200 V can be used for 12 V, 24 V and 48 V batteries.

... due to the two separate inputs
Two inputs each with independent MPP tracking in one charge controller provide greater options when it comes to system planning. With the Steca Tarom MPPT you can not only vary the module types for each input but the circuits too. Series and parallel circuits can be combined easily in one system using the universal and flexible Steca Tarom MPPT. There is no need for an external module circuit box as all module strings can be connected directly to the charge controller leading to significant savings on installation costs.

... due to two maximum power point trackers (MPPT)
The two separate maximum power point trackers enable various module types to be used with just one Steca Tarom MPPT charge controller. Leftover module stock can also be used in a system without any problems. Significantly greater options are also available when upgrading existing systems – without the extra cost of replacing an existing charge controller. The Steca Tarom MPPT is particularly suitable for systems where partial shading of the module array is unavoidable. Due to the two separate MPP trackers, the charge controller can power different strings with an individually adjusted MPP. This enables the maximum efficiency to be exploited for each string enhancing the total output of the system – in spite of partial shading. The same principle applies also for use on roofs or areas with various angles of inclination or orientations.

... due to the comprehensive, integrated data logger
The Steca Tarom MPPT is equipped with a unique, comprehensive data logger, which enables data of the two inputs to be monitored and saved independently over a period of twenty years. The previous 18 hours can be graphically displayed. Daily, monthly and annual totals are summarised automatically for an outstanding overview of system utilisation at a glance.

No need for additional modules!

... due to the extra high efficiency
The Steca Tarom MPPT is one of the few MPPT charge controllers that can reliably attain a high and – more importantly – constant efficiency across all input and output voltage ranges. The high level of reliability of the MPPT solar charge controller enables you to obtain even more power from your PV system. For example, significantly less energy is lost due to unnecessary heat losses. Conversely this means that, using the same power, as much as an entire module can be saved during planning if required. Particularly with limited mounting options or a limited budget this is an indisputable benefit.

Save time and effort during installation!

... due to the easily accessible, easy-to-connect terminals
The extra spacious connection terminal area can be accessed via two screws on the front of the device meaning installation of cables with a thickness of up to 35 mm2 is simple, fast and secure. An integrated module switch means the Steca Tarom MPPT can be connected without any voltage connection, sparks or light arcs. Only when the charge controller is switched on via the menu are the module arrays connected up. This makes installation child‘s play.

Enjoy numerous added benefits!

User-friendly graphical LCD display
All system states are displayed intuitively via icons on the graphical multifunction display enabling simple understanding of the energy flow. All parameters can be configured using the multi-lingual, intuitive menu.

Communication options
The PA HS400 current sensor can be connected via the StecaLink enabling all current flows in the system to be detected. The charge controller also shows the battery‘s current state of charge (SOC). Professional control of loads and generators is possible via the multifunctional contacts.
The Steca Tarom MPPT 6000-M is equipped with three multifunctional contacts, which can be programmed independently of one another. These versatile individual functions can be combined virtually as required:

Function overview of multifunctional contacts:

Deep discharge protection
Deep discharge protection automatically protects the battery against harmfully low levels of discharge. All voltage thresholds can be freely configured via a menu based either on the battery‘s current state of charge (SOC) or on the battery voltage.

Evening, night light and daylight function
The charge controller allows configuration of three different
automatic timer functions: evening light, night light and daylight. All the important time and delay values can be set with this. With the evening light function, the load is automatically switched on at sunset and the time after which the load is switched off again can be individually specified. The night light function specifies the time after which the load is switched on after sunset and switched off again before sunrise. With the morning light function, the load is switched on automatically at night and automatically switched off again at sunrise.

Four freely programmable timers with week day function
The four freely programmable timers can be set individually based on day of the week, start and finish time. With the week day function, each timer can be used for just one or several days of the week at a time if required.

Generator function
Using the generator function, the Steca Tarom MPPT 6000-M – based on the SOC or the battery voltage – can start a generator automatically when the battery is discharged, and switch this off again when the battery is full. Using the surplus manager, an additional load can be activated automatically when the battery is full. This is switched off again as soon as no more energy surplus is available in the solar system. This guarantees that all available energy is used.
