ECOLTO2412 24V 12Ah LTO Solar Tracker Battery 288Wh Integrated MPPT BMS Wide Temperature

Product Overview
The Ecolite ECOLTO2412 is a 24V 12Ah lithium titanate (LTO) battery pack engineered specifically for single-axis and dual-axis solar trackers that move many times a day, every day, for a decade or more. It stores 288Wh of usable energy and ships with an integrated MPPT charge controller and a smart battery management system inside one rugged aluminium enclosure, so a tracker controller can treat it as a complete, self-contained power source. The pack was developed after years of field feedback from utility-scale and commercial tracker farms, where the weakest link is almost always the battery that must follow the array through heat, frost, dust and daily cycling.

Why Lithium Titanate for Continuous Tracking
A tracker never truly rests. It wakes at sunrise, tracks the sun across the sky, stows at night and repeats, asking its battery for thousands of shallow charge and discharge events every year. Lithium titanate chemistry was chosen for the ECOLTO2412 because it tolerates this duty without the capacity fade that shortens ordinary lithium packs. Its spinel anode structure allows fast, low-stress lithium insertion, which is the reason the pack is rated beyond 10000 full cycles yet still returns a healthy capacity after years of service.

Integrated MPPT Maximises Solar Harvest
Because the MPPT controller is built into the pack, the ECOLTO2412 pulls the maximum available power from the tracker panel even when voltage sags under cloud, dust or high cell temperature. Integrating the controller removes a separate box, a second set of terminals and extra cable from the tracker head, which shortens the harness, cuts voltage drop and reduces the number of field failure points. Installers can also parallel a solar panel straight to the pack without an external charge stage.

Smart BMS and Multi-Layer Protection
An onboard smart BMS continuously monitors cell voltage, pack current and internal temperature. If any cell drifts, if current climbs beyond the safe envelope, or if temperature moves outside the permitted band, the BMS isolates the pack to protect both the cells and the tracker electronics. Balancing keeps the twelve amp-hour cells matched through their whole life, so the pack ages evenly instead of running down one weak cell.

Cycle Life and Total Cost of Ownership
The economics of a tracker battery are driven by cycles per dollar, not by purchase price alone. A lead acid block in the same role may survive 500 to 800 cycles before capacity collapses, forcing replacement every few years and adding labour, freight and downtime to the bill. With more than 10000 LTO cycles, the ECOLTO2412 is designed to outlast the tracker arm it powers, turning a recurring maintenance cost into a one-time investment.

Wide Temperature Operation
Tracker farms span deserts, high plateaus and coastal cold. The ECOLTO2412 charges and discharges across -40C to 65C without a heater blanket, so the actuator and control electronics stay alive through the temperature extremes that shut down ordinary lithium packs. Stable performance at low temperature also means the pack is ready to move the array on the first cold morning of the season, when many competing chemistries are still too sluggish to deliver current.

Mechanical Design and Mounting Options
The pack measures 260 x 120 x 45mm and weighs about 4.2kg, light enough to mount directly on the tracker frame without a separate bracket. The aluminium case spreads heat away from the cells during fast charging and resists UV, vibration and dust on outdoor poles. M6 threaded terminals accept standard ring lugs, and the enclosure can be ordered with mounting ears, cable glands and connector types to suit your tracker platform.

Applications and System Integration
The ECOLTO2412 is designed for single and dual axis solar trackers, solar controllers, remote monitoring nodes and electric door systems that need dependable daily energy with minimal maintenance. It pairs naturally with a small PV panel and the tracker actuator, and can be paralleled with additional packs to raise capacity where a larger array demands more stored energy.

FAQ
Q: How many cycles should I expect before replacement? A: The pack is rated beyond 10000 full cycles. Q: Is an external charge controller required? A: No, the MPPT charge function is integrated. Q: Can it run the tracker motor directly? A: Yes, the 60A discharge current covers most tracker actuator loads with margin. Q: Does it need heating in cold climates? A: No, it operates from -40C to 65C without a heater. Q: What documents ship with the pack? A: UN38.3, MSDS, CE and RoHS files are available for every order. Q: What is the delivery lead time? A: 15-25 days for production orders.

Warranty, Shipping and Compliance
Each pack leaves the factory with UN38.3 and MSDS documentation suitable for sea and multimodal transport. A standard one-year warranty covers manufacturing defects, and Ecolite supports extended terms for volume programs. Packaging uses shipping-grade cartons with foam protection, palletised for container loading to keep freight costs predictable.
