Growatt MAX 125K TL3-X LV 125KW 3 Phase On-Grid Solar Inverter

Description

The Growatt MAX 125K TL3-X LV is a heavy-duty, commercial-grade 125kW three-phase on-grid solar inverter designed to convert DC power generated by solar arrays into stable AC power for direct industrial consumption or grid feeding. Operating on a Low Voltage (LV) three-phase network system, it serves as the central power conversion engine for large-scale solar project installations.

In industrial and commercial sectors across Bangladesh, utility power costs represent a significant operational overhead. The MAX 125K TL3-X LV allows factories, textile units, commercial complexes, and agricultural facilities to lower grid power reliance by generating clean, synchronized energy directly on-site. Engineered to perform in hot and humid tropical climates, it offers thermal tolerance, remote system monitoring, and high conversion efficiency to maximize Return on Investment (ROI).

Maintenance Tips

• Inspect external cooling fans every 6 months to clean out accumulated dust and debris.
• Check LED indicator status or remote APP logs monthly for warning codes or array mismatch indicators.
• Verify physical tightness of external AC and DC electrical terminals annually.
• Ensure heat-sink cooling fins behind the unit remain unobstructed.

Safety Instructions

• Installation must be performed exclusively by qualified certified solar engineers.
• Isolate both DC isolator switches and main AC breakers prior to working on electrical terminals.
• Wait a minimum of 5 minutes after switching off power to allow internal capacitors to discharge completely.
• Ensure proper earthing/grounding connections (PE) are secured before powering up the inverter.
