We are proud to offer this advanced controller from Steca Electronik; the global leader in off-grid solar electronics. All Steca controllers are able to control the entire energy flow in any power system, whilst ensuring optimal battery maintenance. German design, engineering and manufacturing ensure unrivalled standards of quality and efficiency.
This Steca Tarom M-Type 60A MPPT charge controller sets unprecedented standards in the field of Maximum Power Point trackers. Due to its continued outstanding achievements in the solar industry, it was awarded the renowned OTTI Innovation Prize and the Intersolar Award in 2014. With two independent MPP trackers and two solar inputs, this MPPT controller can easily handle two different solar module arrays of varying sizes.
The controller is designed to protect batteries whilst charging them, providing automatic cut off to prevent over-charging and deep discharge. It comes with an automatic electronic fuse and a full range of electronic protection functions, including protection against: overload, short circuit, high voltage, reverse polarity, high temperature, lightning and transient surges, reverse current at night.
This M-Type model has the ability to communicate with up to 22 Steca Tarom MPPT S-Type controllers in one network (connected to the same battery bank), offering possibilities for system expansion at a later date. When multiple S-type controllers are connected, this controller will intelligently synchronise their actions and charging stages to ensure that a safe and stable voltage is maintained accross the entire system, regardless of varying cable lengths.
Other key features include:
- Extremely high reliability, with an integrated self-test function and a long 5 year warranty
- Unique MPP trackers which work constantly at high efficiency ratings of up to 99%
- Compatible with lead-acid, lithium-ion or NiCd batteries, with personalised settings for each type
- Automatic data logging of energy values for 20 years, with a MicroSD slot for logging of detailed values
- Intelligent output terminals (can be programmed for load management, e.g. to activate a generator when the battery is low or to divert excess energy to an electrical appliance)
- Programmable current limiting function which allows the input current to be limited to a specific value (e.g. for temporary charging of a smaller battery bank)
- Easy to use LCD display
This solar charge controller is suitable for solar panels with a maximum power of up to 850W (12V battery bank), 1700W (24V battery bank) or 3400W (48V battery bank) and is also compatible with 36V or 60V batteries by activating advanced settings in the expert menu.
