Solis S6-EH3P20K-H 20kW 3 Phase Hybrid Solar Inverter

Description

The Solis S6-EH3P20K-H is an advanced 20 kW three-phase high-voltage hybrid solar inverter engineered to deliver complete power security and energy optimization for commercial buildings, manufacturing workshops, and modern industrial facilities. It unifies high-efficiency solar panel generation, high-voltage battery storage control, and 3-phase utility grid connection into a single intelligent power control system.

Operating synchronously on 3-phase 380V/400V grid lines, it prioritizes self-generated DC solar power for building loads and charges connected high-voltage (150V–800V) battery storage arrays. During utility grid failures, its integrated backup port switches in less than 10 milliseconds to deliver UPS-grade emergency power across all three phases. In Bangladesh, where rising industrial utility tariffs and sudden grid outages disrupt production lines, the S6-EH3P20K-H provides a robust, heat-resilient, and cost-effective hybrid energy solution.

Installation & Maintenance Guide

Installation Requirements:

• Wall-mount vertically in a well-ventilated plant room or covered wall area capable of supporting heavy industrial inverter equipment safely.
• Maintain clear airflow space (at least 50 cm top and bottom, 30 cm on sides) for effective active cooling fan circulation.
• Install appropriately rated UV-resistant DC solar cables, high-voltage battery cables, and 3-phase AC circuit breakers matching grid codes.
• Ground the chassis securely to a dedicated electrical earthing pit to defend against surge and lightning damage.

Maintenance Tips:

• Routinely clean side air intake vents and heatsinks to clear dust, fibers, and atmospheric debris.
• Perform annual physical inspections of AC, DC, and battery terminals to confirm secure, corrosion-free contacts.
• Monitor real-time performance logs via the SolisCloud mobile app to detect string imbalances or grid fluctuations early.

Safety Instructions:

• Installation and commissioning must be carried out by senior electrical engineers or certified solar installers.
• Isolate DC solar array strings, high-voltage battery circuit breakers, and 3-phase AC mains feeds before opening connection covers.
• Never attempt internal repairs while connected to live energy sources.
