This document describes the EAPRO TRON AI-MPPT MPPT Off-Grid Hybrid Solar PCU, an energy-efficient power control unit designed for various applications.

Function Description:

The EAPRO TRON AI-MPPT is an MPPT Off-Grid Hybrid Solar PCU (Power Controlling Unit) that utilizes Pure Sine Wave technology and an inbuilt Real-Time Clock (RTC). Its primary function is to optimize solar power utilization for maximum power saving, providing a reliable power source for commercial, domestic, or industrial electronic appliances. The device intelligently tracks the sun's position and manages power absorption from a solar array. It can operate in dual modes: UPS and Normal. In UPS mode, it offers fast switching and an input voltage range of 180V to 270V. In Normal mode, it has a wide input operating range of 90V to 290V (or 100V to 290V for 3000VA and above models). The PCU prioritizes solar power, intelligently supplementing with grid power only when necessary. It also features an active battery reverse protection system and an inbuilt fully regulated MPPT charge controller.

Maintenance Features:

• Safety Precautions: The manual emphasizes reading all instructions and warnings to prevent damage and injury. It advises against disconnecting battery cables while the PCU is delivering power, using only deep cycle lead-acid batteries, and ensuring proper grounding.
• Battery Maintenance: Servicing should be performed by knowledgeable personnel. When replacing batteries, use the same type and number. Precautions include not disposing of batteries in fire, not opening or damaging them, removing metal objects, using insulated tools, wearing rubber gloves and boots, and disconnecting charging sources before connecting/disconnecting battery terminals.
• Troubleshooting Guide: Provides solutions for common problems such as no LCD indication, overload faults, short circuit faults, thermal trips, fuse/MCB trips, PV reverse faults, low surge power, empty battery blinking, and LCD communication errors.
• Installation Check List: An essential checklist for higher rating models, covering environment conditions (noise, dust, ventilation), mains input (earthing pits, voltages, frequency), solar input (panel count, current, circuit breaker rating), output (voltage, frequency, load), battery (wire thickness, capacity, make, date), and earthing.
