Crown Micro Voltmore 3KW Single Phase On Grid PV Inverter

Description

The Voltmore 3 KW Single Phase On-Grid PV Inverter is a high-efficiency solar string inverter designed to power residential homes, small offices, and retail shops using clean solar energy. Working directly with your rooftop photovoltaic panel array, it converts Direct Current (DC) into 230V Alternating Current (AC) synchronized with the utility grid.

In Bangladesh, where electricity tariffs continue to rise for residential and small commercial consumers, this 3 kW on-grid inverter offers a cost-effective path toward energy independence. By supplying day-to-day electrical loads directly from rooftop panels and enabling net metering export during peak sunlight hours, it significantly reduces monthly grid power expenses.

Key Features

• High Efficiency Tracking: Integrated Maximum Power Point Tracking (MPPT) maximizes energy yield from PV modules under varying sunlight intensity.
• Grid Synchronization: Provides smooth, low-distortion 230V single-phase power output that seamlessly integrates with local power lines.
• Rugged Enclosure: IP66 degree of protection prevents dust, moisture, and rainwater ingress during extreme weather conditions.
• Comprehensive Electrical Protection: Integrated anti-islanding protection, DC reverse polarity protection, surge protection, and short-circuit safeguards.
• Digital Interface & Remote Tracking: Built-in communication channels (RS485 / Wi-Fi) allow users to monitor daily power generation and system stats remotely.

Technical Advantages

• High Efficiency: Up to 97.6% peak conversion efficiency ensures minimal heat loss and maximum kilowatt-hour generation.
• Durable Construction: Built with high-grade aluminum enclosure materials to resist tropical corrosion and heat stress.
• Safety Protection: Multi-stage internal safety features shield connected home appliances and grid connection points.
• Energy Saving: Ultra-low self-consumption during standby modes maximizes usable daytime power output.
• Easy Maintenance: Fanless natural cooling design reduces moving mechanical parts, lowering long-term maintenance needs.

Applications

• Residential: Perfect for single-family homes, villas, and apartment rooftops running lighting, fans, refrigerators, and small AC units.
• Commercial: Ideal for small retail shops, bakeries, pharmacies, and service centers looking to offset daytime power bills.
• Industrial: Suitable for small-scale repair workshops or site offices requiring supplemental 230V single-phase power.
• Factory: Fits ancillary administrative blocks and security outposts within factory compounds.
• Office: Powers small office spaces, workstations, IT equipment, and administrative setups during daylight hours.
• Project Installation: Excellent choice for distributed residential solar power projects across urban and semi-urban Bangladesh.

Installation & Maintenance Guide

Installation Requirements:

1. Location: Wall-mount vertically on a sturdy concrete or metal structure shaded from direct afternoon sun exposure.
2. Clearance: Leave at least 30 cm of clear space on all sides to allow proper natural air movement across heat sinks.
3. Wiring: Use appropriately rated UV-resistant DC solar cables (e.g., 4 mm²) and standard single-phase AC copper wiring with AC/DC protection boxes.
4. Earthing: Install dedicated DC frame grounding and AC safety earth connections before energizing the system.

Maintenance Tips:

1. Clean the external heat sink fins with a soft brush every six months to clear dust accumulation.
2. Inspect AC and DC terminal connections annually for tightness and cable integrity.
3. Keep the outer enclosure free from cobwebs or bird nests to ensure unhindered thermal dissipation.

Safety Instructions:

1. Always turn off the DC isolator switch and AC breaker before attempting any physical inspection or service wiring.
2. Allow internal capacitors to discharge for at least 5 minutes after disconnecting power sources.
3. Installation must be conducted by a qualified electrician or experienced solar project engineer.

FAQ Section

Q: What is the price of Voltmeter 3 KW Single Phase On grid PV Inverter in Bangladesh?

A: The price of a 3 kW single-phase on-grid solar inverter in Bangladesh generally ranges depending on exchange rates and stock availability. Please check loopshop.com.bd for the latest updated price and promotional offers.

Q: Where can I buy Voltmeter 3 KW Single Phase On grid PV Inverter in Bangladesh?

A: You can purchase genuine 3 kW single-phase on-grid PV inverters online directly at loopshop.com.bd with delivery and technical support across Bangladesh.

Q: What warranty does this product have?

A: This 3 kW on-grid inverter comes with a standard 5-year manufacturer warranty covering internal component defects under normal operating conditions.

Q: Is this suitable for Bangladesh climate?

A: Yes, featuring an IP66 ingress rating and operating thermal limits up to 60°C, it is well suited for humid summers, monsoons, and dusty local environments.

Q: How to install this product?

A: Mount the inverter vertically on a wall, connect the incoming DC solar strings through a DC breaker box, wire the 230V AC output to your single-phase distribution panel, establish proper grounding, and commission the grid power feed.

Q: Does a 3 kW on-grid inverter require batteries to operate?

A: No, an on-grid PV inverter works without batteries by feeding solar energy directly to your home loads and grid synchronization.
