Applications of the Super Multi Box (Smart DC Combiner)<\/h2>\n\n\n\n

The Super Multi Box is an intelligent DC combiner for PV systems up to 1,500 V DC. It is suitable for PV projects with high availability and monitoring requirements, as well as for demanding projects where multiple strings need to be combined, monitored, and selectively disconnected if necessary.<\/h3>\n\n\n\n

It is used particularly when multiple PV strings are routed to a central inverter \u2013 often with only one MPPT \u2013 and a single insulation or string fault must not lead to a complete system shutdown.<\/p>\n\n\n\n

Smart DC Combiner with Patent-pending PV String Fault Discriminator
\u2013 Selective fault isolation with system<\/h2>\n\n\n\n

The patent-pending PV String Fault Discriminator is the central functional element of the Super Multi Box. It enables the selective detection and isolation of individual faulty PV strings within a DC combiner, thereby preventing a complete system shutdown in the event of insulation or string faults in central inverter architectures. <\/p>\n\n\n\n

Technical background: Central inverters and insulation faults<\/h3>\n\n\n\n

In conventional DC combiner solutions, an insulation fault, arc fault, or string fault often causes all connected PV strings to be shut down together, as differentiated fault assignment at the string level is not possible. Particularly in central inverter architectures with only one MPPT, this leads to a complete standstill of the affected generator field \u2013 even though usually only a single string is actually faulty. <\/p>\n\n\n\n

The Super Multi Box takes a different approach: it utilizes a central master logic in combination with the patented PV String Fault Discriminator to specifically identify faulty strings, shut them down selectively, and maintain the operation of the remaining generator fields.<\/strong><\/h3>\n<\/div>\n<\/div>\n\n\n\n
<\/div>\n\n\n\n

\n

The process in the event of an insulation fault<\/strong><\/strong><\/h2>\n\n\n\n
<\/div>\n\n\n\n

If an insulation fault occurs in a string, the inverter first detects an impermissible insulation state and initially shuts down the generator.<\/p>\n\n\n\n

The Master Super Multi Box receives this error message and automatically initiates a structured identification process:<\/p>\n\n\n\n

\n
<\/i>

All connected DC combiners are shut down in a controlled manner<\/strong><\/p><\/div>\n\n\n\n

<\/i>

The combiners are switched back on one after the other<\/strong><\/p><\/div>\n\n\n\n

<\/i>

If the fault reoccurs when a specific combiner is switched on, the fault-causing unit is identified<\/strong><\/p><\/div>\n\n\n\n

<\/i>

The affected combiner is shut down again<\/strong><\/p><\/div>\n\n\n\n

<\/i>

The defective string is selectively isolated within the combiner<\/strong><\/p><\/div>\n\n\n\n

<\/i>

The combiner restarts without this string<\/strong><\/p><\/div>\n\n\n\n

<\/i>

The inverter then no longer detects an impermissible insulation state<\/strong> \u2013 the remaining PV strings remain available.<\/strong><\/p><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n

The Super Multi Box DC combiner works differently. Thanks to the patent-pending PV String Fault Discriminator, a fault does not lead to a blanket shutdown of the generator, but is instead systematically identified. Following the inverter’s fault message, the connected SMB units are automatically switched on sequentially, the fault-causing string is clearly localized and selectively isolated. The remaining part of the system continues to operate. <\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n

Conventional DC Combiner vs. Smart DC Combiner Super Multi Box<\/strong><\/h2>\n<\/div>\n<\/div>\n\n\n\n
\n
\n
\n

In conventional DC combiner solutions, an insulation fault often leads to the shutdown of an entire generator section. Particularly in central inverter architectures with only one MPPT, this means: the inverter detects an impermissible insulation state and shuts down the affected generator section \u2013 even though usually only a single PV string is affected.

The consequence:<\/p>\n\n\n\n

\u25a0 Complete standstill of a generator field

\u25a0 Manual, time-consuming troubleshooting in the field

\u25a0 Unnecessary yield losses

The Super Multi Box is not just a component assembly, but a tested system solution. The combination of: <\/p>\n\n\n\n

\u25a0 Custom design
\u25a0 Selective fault isolation
\u25a0 Integrated measurement technology
\u25a0 Communication interfaces<\/p>\n\n\n\n

creates a technically coordinated DC combiner system for high system availability, long-term operational reliability, and reduced service calls in the MW range.<\/p>\n\n\n\n

Particularly in utility-scale and MW ground-mounted systems, the electrical design of the DC combiner system determines system availability, service effort, and long-term operational reliability.<\/strong><\/h4>\n<\/div>\n\n\n\n

\n

Would you like to have the Super Multi Box designed for your PV project \u2013 including PV String Fault Discriminator, optional individual string current measurement, communication (Modbus\/Ethernet), and matching protection components?<\/strong><\/strong>

Using the inquiry form below, we capture your project data in a structured and transparent manner \u2013 so that you quickly receive a technically suitable and economical system solution.<\/p>\n<\/div>\n\n\n\n

\n

You are welcome to send string plans, wiring\/circuit diagrams, inverter data, Isc values, as well as grounding and protection concepts directly. Based on this, we check the boundary conditions (including number of strings, architecture, monitoring requirements) and configure the Super Multi Box to fit your project. If any questions arise, we will coordinate the details directly with you \u2013 otherwise, you will receive a project-specific offer promptly. <\/em><\/em><\/em><\/p>\n\n\n\n
