Overview

The EcoBoost MPPT™ solar charge controller brings Morningstar's proprietary TrakStar Technology™ to their Essentials controllers and accessories. The EcoBoost controllers automatically detect 12 or 24 V system configuration, are highly efficient and accurate and designed to ensure that batteries attain a complete state of charge. They are also sophisticated load controllers. Using this feature to manage DC power consumption protects the batteries from over discharge and helps ensure long term system reliability. Small DC loads can be powered directly from the EcoBoost by way of two USB charging ports Morningstar EcoBoost controllers act as the central brain of PV powered DC electrical systems up to 1,120 watts and offer outstanding value, performance and dependability. Features High Reliability – conformally coated circuit board and corrosion resistant terminals. Maximizes Energy Harvest – using TrakStar MPPT Technology to determine and adjust to the true maximum power point as solar insolation changes throughout the day. High Efficiency – at low, medium, and high power levels. Low Noise Design – One of the electrically quietest controllers in this size and price range. Optional Meter – provides access to system operational information including current and historical performance data. All EcoBoost "M" controllers include the meter. USB Charging – Two USB ports with 3 amps of shared charging capacity. USB Data – Retrieve locally stored performance data. Use port for serial emulation for real-time view of system operation. Self Diagnostics – continuous monitoring and reporting of any errors through its status LED’s, or its optional display. Lighting Controller – Uses PV array to switch at dusk and dawn. Load Controller – Connect DC loads directly to the controller. Programmable load operation and protects batteries. Data Logging – up to 30 days of detailed power and load data. 2 year warranty

How to read this datasheet

Morningstar EcoBoost MPPT™ is listed with 7 published specifications from Morningstar, including system battery voltage of 12V, 24V, max VOC of 120V, MPPT trackers of 1 and connection of Screw terminals. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.

For a charge controller, the figures that matter most are maximum PV open-circuit voltage, the hard limit that must survive cold-morning Voc rise, supported battery voltages (12/24/36/48 V) and chemistries, conversion efficiency, typically 96–99% for a good MPPT unit and whether it offers a load output, temperature compensation and remote monitoring. In any system with a battery and a separate array, the controller is what protects the most expensive component and determines how much of the array's output actually reaches storage.

What to check before ordering

The checks below apply to any charge controller. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.

Prefer a unit with temperature compensation or a battery temperature sensor if the bank lives somewhere that gets hot or cold.
Choose MPPT over PWM for anything beyond a very small array. An MPPT controller harvests roughly 20–30% more energy because it converts excess panel voltage into charge current instead of throwing it away.
Size the current rating from array watts divided by battery voltage, then add at least 25% margin for cold, bright conditions where panels exceed their rated output.
Check the maximum PV input voltage against the array's Voc at your coldest expected temperature, not at 25 °C — Voc rises as temperature falls, and exceeding the limit destroys the controller instantly.

Common mistakes

Sizing on rated array watts alone and ignoring the voltage ceiling, which is the most common way controllers are killed.
Using a PWM controller with a high-voltage grid-tie panel — the voltage mismatch wastes a large share of the panel's output.
Running the load output beyond its rating instead of wiring heavy loads directly to the battery through a fuse.

Price and availability in United Kingdom

Morningstar EcoBoost MPPT™ is listed at £ 135 (GBP) for United Kingdom. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.

SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in United Kingdom: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Morningstar locally before ordering.

Morningstar EcoBoost MPPT™ — frequently asked questions

How much does Morningstar EcoBoost MPPT™ cost?

Morningstar EcoBoost MPPT™ is listed at £ 135 (GBP) for United Kingdom. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.

What are the specifications of Morningstar EcoBoost MPPT™?

We hold 7 published specifications for this charge controller, including system battery voltage 12V, 24V, max VOC 120V, MPPT trackers 1, connection Screw terminals and weight (kg) 1.3. The full table is on this page, listed under model EB-MPPT-20.

Who makes Morningstar EcoBoost MPPT™?

Morningstar EcoBoost MPPT™ is a Morningstar product, listed under charge controllers with model reference EB-MPPT-20. The Morningstar brand page lists the rest of its range so you can compare across the catalogue.

Is Morningstar EcoBoost MPPT™ right for my system?

That depends on what it has to connect to. For a charge controller, check type: MPPT or PWM, rated charge current in amps, which must exceed the array's short-circuit current with margin and maximum PV open-circuit voltage, the hard limit that must survive cold-morning Voc rise against the rest of your equipment before price enters the decision. Choose MPPT over PWM for anything beyond a very small array. An MPPT controller harvests roughly 20–30% more energy because it converts excess panel voltage into charge current instead of throwing it away.

Where can I buy Morningstar EcoBoost MPPT™ in United Kingdom?

SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in United Kingdom — buying in-channel is what keeps the manufacturer's warranty valid.
