20kW 3-Phase Commercial On-Grid Solar Inverter for Industrial Projects

Description

The 20kW 3-Phase Commercial On-Grid Solar Inverter is a high-efficiency string solar inverter engineered for commercial, industrial, and institutional rooftop solar power generation. It converts Direct Current (DC) electricity generated by photovoltaic solar panel arrays into clean, balanced, grid-synchronized 3-phase Alternating Current (AC) electricity to run machinery, HVAC systems, and facility power grids.

Operating in direct synchronization with standard 3-phase 380V/400V utility power lines, it feeds self-generated daytime solar electricity into the facility’s main distribution network, directly substituting expensive utility grid consumption. Under Bangladesh’s Net Metering Guidelines, surplus power generated during daytime sunlight hours can be exported back to the grid (BPDB, BREB, DPDC, DESCO, or WZPDCL). This inverter provides a durable, heat-resilient, and cost-effective energy transformation engine for Bangladesh’s commercial and industrial enterprises.

Key Features

• Multi-MPPT Solar Trackers: Features multiple independent MPPT channels to maximize power harvest from solar arrays mounted across different roof pitches or subject to partial shading.
• High Conversion Efficiency: Advanced power electronics topology delivers optimal energy conversion efficiency to minimize internal thermal power losses during peak daylight hours.
• Smart Grid Synchronization: Rapidly locks phase angle and frequency with 3-phase 380V/400V grid lines for smooth, flicker-free energy injection.
• Anti-Islanding Safety Protection: Built-in anti-islanding safety features automatically shut off inverter output during utility outages to protect grid maintenance workers.
• Industrial Weatherproof Housing: Housed inside a heavy-duty chassis with robust ingress protection against dust infiltration, moisture, and high thermal stress.

Technical Advantages

• High Efficiency: Maximizes kilowatt-hour yield per watt of installed solar panels using high-precision power tracking algorithms.
• Durable Construction: Built with industrial-grade semiconductor components and heat-dissipation management designed for continuous full-load operation.
• Safety Protection: Comprehensive electrical safety suite including DC reverse polarity protection, AC short-circuit protection, over-voltage/under-voltage protection, and insulation monitoring.
• Energy Saving: Ultra-low night-time standby self-consumption minimizes parasitic grid power draw during non-generating hours.
• Easy Maintenance: Remote telemetry logging, event diagnostics, and modular internal layouts facilitate straightforward routine servicing and maintenance.

Applications

• Residential: Large shared residential housing complexes, luxury estates, and institutional quarters.
• Commercial: Shopping centers, corporate branch offices, hotels, and private healthcare facilities.
• Industrial: Garment assembly workshops, textile processing units, printing presses, and light manufacturing plants.
• Factory: Production lines, administrative complexes, cold storage units, and packaging stations.
• Office: Corporate IT hubs, bank data centers, and multi-story institutional office blocks.
• Project Installation: Commercial rooftop solar projects, industrial net-metering installations, and utility-assisted solar arrays across Bangladesh.

FAQ Section

Q: What is the price of 20kW Solar On Grid Inverter in Bangladesh?

A: The price of a 20kW 3-Phase On-Grid Solar Inverter in Bangladesh depends on the brand manufacturer, efficiency rating, and warranty terms. Please check loopshop.com.bd for current prices and quotes.

Q: Where can I buy 20kW Solar On Grid Inverter in Bangladesh?

A: You can purchase genuine 20kW Commercial On-Grid Solar Inverters online directly at loopshop.com.bd with nationwide delivery.

Q: What warranty does this product have?

A: Commercial 20kW on-grid inverters standardly include a 5-year manufacturer warranty supported by local technical service assistance.

Q: Is this suitable for Bangladesh climate?

A: Yes. It features robust thermal management and weatherproof casing designed to handle Bangladesh’s hot summer temperatures, humidity, and heavy monsoon seasons.

Q: How to install this product?

A: Mount the unit vertically on a structural wall, connect multi-string DC inputs from your solar array, and wire the 3-phase AC output directly to your facility’s main distribution board following grid rules. Professional installation is required.

Q: Does a 20kW on-grid inverter work during a load shedding power cut?

A: No. Grid-tied inverters require an active utility grid signal to function. During a power cut, the anti-islanding protection automatically shuts off the unit to prevent feeding power into lines being serviced by grid workers.

Q: Can I use this 20kW inverter for net-metering in Bangladesh?

A: Yes, 3-phase on-grid solar inverters are fully compatible with net-metering guidelines approved by BPDB, BREB, DPDC, DESCO, and WZPDCL.

Q: What is the benefit of Multi-MPPT in a 20kW inverter?

A: Multi-MPPT allows solar panels installed across different roof orientations or pitch angles to operate independently without shading on one string hurting the output of others.

Q: How much electricity can a 20kW solar system generate daily in Bangladesh?

A: On average, a 20kW solar installation in Bangladesh generates between 75 kWh and 95 kWh of AC electricity per day, depending on seasonal sunlight and panel cleanliness.

Q: Can I monitor power production on my mobile phone?

A: Yes, by attaching a Wi-Fi, LAN, or 4G datalogger stick, you can track daily power generation and system stats via a mobile app or web portal.
