TriStar TS-45 Solar Controller

45 Amp | 12-48V | Professional PWM Regulation

The Morningstar TriStar TS-45 is a sophisticated three-function controller that provides reliable solar battery charging, load control, or diversion regulation. Designed for both residential and professional off-grid applications, it features a robust, fan-less thermal design that ensures long-term reliability even in harsh environments. With its ability to auto-detect system voltage (12V, 24V, or 48V), it is one of the most versatile PWM controllers on the market.

RELIABILITY: Built with a large heat sink and conservative electronic design for full-power operation up to 60°C without de-rating.

Manufacturer Morningstar Corporation
Part Number (MPN) TS-45
Secondary SKU MS-TS-45, SLR-520-0045

Installation Guide

Mount the controller vertically for optimal convection cooling. Ensure sufficient clearance (15cm) above and below the unit. Connect the battery first, then the solar array. For 48V systems, ensure the maximum input voltage (Voc) does not exceed 125V. Use the RS-232 port for advanced PC-based configuration if custom charging profiles are required.

Questions & Answers

Is this a genuine original part?

Yes, this is a genuine Morningstar TriStar product, known globally for its extreme durability and precision engineering in professional solar installations.

How do I know if it is compatible?

We recommend checking the SKU/MPN (TS-45). This unit is compatible with 12V, 24V, or 48V battery banks and handles up to 45 Amps of current. It can be used for solar charging, load control, or diversion (e.g., wind/hydro).

Can I use two TS-45 units together?

Yes. Two or more controllers can be used in parallel for larger solar arrays (up to 300A or more) or to provide multiple functions (e.g., one for charging and one for load control).

Note: Please verify your system voltage and solar array open-circuit voltage (Voc) against the references above before purchasing. Distributed by Solarika.
