Overview

The Ameresco Solar ASM-PS15 is a fully pre-wired aluminum back plate assembly built around the Morningstar ProStar 15 (PS-15) PWM charge controller. Designed for rapid deployment of small industrial, telemetry, off-grid, and remote power systems, the ASM-PS15 integrates the charge controller, DC breakers, DIN-rail terminal blocks, and wiring harnesses into a clean, ready-to-mount power panel. This drop-in solution reduces install time, ensures correct wiring practices, and provides a reliable foundation for 12 V or 24 V battery-based solar power systems.

Key Features

  • Factory pre-wired assembly: All controller, breaker, and terminal wiring pre-installed for fast field deployment.
  • Integrated Morningstar ProStar 15: Industry-standard 30 A PWM controller with built-in metering, LVD, and battery type selector.
  • DIN-rail mounted terminal blocks: Supports up to 4 PV modules and 4 batteries depending on system voltage (12 V / 24 V). 
  • Includes DC circuit breakers: Dedicated PV, load, and battery breakers installed and labeled.
  • Rugged aluminum back plate: Corrosion-resistant mounting surface designed for harsh outdoor and industrial environments.
  • #10 AWG battery-to-regulator wiring kit: Pre-terminated cables included for proper gauge and polarity.
  • Supports 12 V and 24 V systems: Diagrams included for both voltage configurations.
