SolarMagic™ Power Optimizers  

Today’s photovoltaic arrays are defined as strings of series-connected PV panels, which are then paralleled together and converted to AC power through an inverter. The key challenge of these arrays is how a small amount of real-world mismatch with just a few of the PV panels can cut the power output of the entire array in half. This mismatch can come in the form of shading (e.g. trees, chimneys, overhead power lines, bird droppings, handrails, etc.), panel-to-panel mismatch, different panel orientations and tilts, or different string lengths.

As a result of these mismatches, system integrators are often forced to compromise their installation by various methods, such as reducing the size of the array to avoid shade, accepting a lower energy output per square meter, or adding extra panels in a different part of the array, all of which cost money, efficiency, and/or aesthetics for the system owner.

To maximize the energy output of each solar PV panel in the array, National Semiconductor has developed SolarMagic technology, which enables each solar panel to produce the maximum energy regardless of whether other panels in the array are under-performing due to mismatch. SolarMagic technology monitors and maximizes the energy harvest of each individual PV panel through advanced algorithms combined with leading-edge mixed-signal technology, thereby recouping up to 57% of the lost energy due to mismatches.

The SolarMagic power optimizer is designed to be installed quickly and easily within the traditional architecture of a solar array. Each power optimizer comes with a universal mounting bracket for easy attachment to a racking system. The output wires of each solar panel are simply series-connected to a power optimizer (positive wire to positive wire, negative to negative), with the power optimizer output wires correspondingly connecting into the next solar panel’s power optimizer.

A single blocking diode must be installed in each assisted string to protect the SolarMagic power optimizers from damage.

All SolarMagic power optimizers come with a limited 20-year warranty, thereby ensuring the reliability of the panel-mounted electronics matches the panels themselves.

SolarMagic™ Blocking Diodes  

The blocking diode is designed to block reverse current flow by allowing current to flow in one direction and disconnect the circuit if current attempts to flow in the opposite direction. Due to the interaction, strings with SolarMagic power optimizers installed – also referred to as assisted strings – will have varying voltage levels during energy production hours.

A single blocking diode must be installed in each assisted string to protect the SolarMagic power optimizers from damage.

All SolarMagic blocking diodes come with a full 20-year warranty.

SunMizer DC Power Optimizer

SunMizer is a per-module DC-to-DC power optimizer that performs MPP tracking at the PV module substring level to increase array power harvest. SunMizer achieves maximum power flow from the module during sub-optimal module operating conditions caused by shade and soiling to recover more than half of system level power loss. Modules can now be placed on roof space that would not have been utilized in the past because modules in these areas would actually decrease system output. In addition, SunMizer optimized modules can be installed in locations to match the roofline, avoiding odd shapes and cut-outs.

Use one on each module that will be shaded.

Selective installation gives SunMizer a unique advantage over competing DC power optimizers that require a unit on each module in a string. SunMizer can be installed selectively, only on the solar modules that experience regular shade or soiling. Selective installation provides optimized power output at a lower initial cost than a fully installed solution. SunMizer is lightweight (< 2 kg) and its compact dimensions of 6" x 4" x 1.6" (15 x 10 x 4 cm) make it easy to install directly to module racking with standard rack system 5/16 or 1/4 inch fasteners. Each unit has an integral grounding lug that also accepts a ring terminal connection. SunMizer is connected in-line with PV modules using standard series wiring schemes and does not require specialized wiring, or add-on equipment. SunMizer is compatible with solar modules that have 54-60 156m m cells. Modules with a maximum power rating of 250W (Pmax), no more than 48V (Voc), and 9A (Isc) can be used with the SunMizer. SunMizer is compatible with most 208V and 240V residential size inverters. SunMizer is made in the U.S. TUV certified to the UL 1741 safety standard. 20-year warranty includes a replacement labor provision.
 

mproved Roof Utilization and Aesthetics

With SunMizer, the system designer can now install more panels and increase system power production.  Panels can now be placed on roof space that would not have been utilized in the past because panels in these areas would actually decrease system output.  In addition, SunMizer optimized panels can be installed in locations to match the roofline, avoiding odd shapes and cut-outs.  This makes for a more attractive and aesthetically pleasing solar array.  More power with an attractive system, a win-win for the system owner and the designer.  

Selective Installation

"Selective Installation" gives SunMizer a unique advantage over competing DC/DC power optimizers that require a unit on each panel in a string.  SunMizer can be installed selectively, only on the solar panels that experience regular shade or soiling.  Selective installation provides optimized power output at a lower initial cost and that means faster return on investment for the system owner.

Compatibility and Installation

SunMizer is lightweight (> 2 kg) and its compact dimensions of 6" x 4" x 1.6" (15 x 10 x 4 cm) make it easy to install directly to panel racking with standard rack system fasteners and nuts.  Each unit has an integral grounding lug that also accepts a ring terminal connection.  SunMizer is currently compatible with a wide variety of popular rack mounting systems.  SunMizer is connected in-line with PV panels using standard series wiring schemes and does not require specialized wiring or “add-on” equipment.

SunMizer is compatible with a large list of 156mm cell architecture models from most major panel manufacturers worldwide.  Panels with a maximum power rating of 250W (Pmax), 48V (VOC), and 9A (ISC) or 350W (Pmax), 80V (VOC), and 7A (ISC) can be used with SunMizer (see product specification sheet).  SunMizer is compatible with most 208V and 240V residential size inverters.

Data Sheet
Tigo Energy Module Maximizer-EP (MM-EP)

For residential, commercial and utility scale photovoltaic solar arrays, the TIGO Energy® Maximizer™ system optimizes power output of each module (solar panel); delivers module-level data for operational management and performance monitoring; provides the ability to deactivate the high voltage DC bus for safer installation maintenance or fire fighting.  TIGO Energy™ Module Maximizers are key components of the system which reside at each module (one per solar module).  The Module Maximizer provides data acquisition, communication to the TIGO Energy® Maximizer™ Management Unit, energy harvesting control, and galvanic isolation.  The very small electronics footprint has been designed to minimize cost and maximize reliability.

The TIGO Energy output optimization starts with dynamic module balancing – a Module Maximizer (patent pending) attached to each module manages the energy harvest and sends information to the Maximizer Management Unit for reporting and control.  The Parallel Module Maximizer (MM-EP) is available with or without module level isolation and is connected in either a series or parallel topology.  MM-EP maintains best-in-class system conversion efficiencies. The fixed voltage bus also allows the system to work at the optimal voltage range of the inverter, eliminating the need for DC pre-conditioning stage while increasing the inverter’s AC conversion efficiency.
Data Sheet

Active System Management

The Tigo Energy management software provides greater control over performance with module-level granularity, alerts, maintenance reports, and many other applications. By understanding the performance levels of each system component, maintenance can be quickly and effectively performed. On-demand maintenance reports help crews directly target problem areas which greatly reduces time in the field and O&M costs. They can arrive at the site with the correct replacement components and tools to get the job done quickly. The Tigo Energy PV-Safe feature allows system owners to disconnect the module from the bus at the Maximizer. This application can be activated with a safety button located on the Management Unit or via a remote command console. This allows for system installation, maintenance, and emergency work to be done without endangering personnel with high DC voltage.

Each TIGO Energy Maximizer system (patent pending) includes one MMU per project, with the option of a second unit for system redundancy.  The MMU has a manual user interface and LCD disply housed in a NEMA-3 enclosure for onsite programming.  The MMU mounts near the inverter and communicates with each PV module in the system, provides management and controls functions for the module Maximizers, and serves as a gateway to the Data Center.  The Maximizer Management Unit is pre-configured with CAT-5 Ethernet access and can ship with optional wi-fi or cellular communication modules.  The MMU can be used as a qualifying inverter and overall system performance monitoring interface for legacy installations.

Secure remote access to the MMU via the TIGO Energy™ MaxiManager software applications is available through any internet-enabled computer, with views available for system owners, installers, power plant operators and emergency service personnel.  Simple, easy-to-understand graphics allow for quick analysis of the real-time output and historical performance of each system, and the ability to view and remedy system faults, error codes or alerts.
Data Sheet

MaxiManager Software

The TIGO Energy™ Maximizer System accelerates PV project payback and lowers the cost of generating solar energy.  The system increases power harvest by implementing localized MPPT at each module (solar panel), monitors module level for additional operational efficiencies, and greatly improves system safety.  As a key component of the system, the TIGO Energy MaxiManager software manages the entire PV array so that if problems occur, they can be addressed immediately. System analytics track performance relative to expectations and proactively suggests maintenance actions to keep the system operating at maximum production and uptime.
