Inverter Configuration:

• System Rating: Confirm the inverter capacity and whether 50 kW denotes AC output or PV capacity.
• AC Supply: Specify voltage, frequency, phase and connection mode.
• Monitoring and Protection: Confirm metering, communications, isolation and fault protection for the selected inverter and project design.

Charge Controller Reference:

• Listed Model: Namkoo-SCR-001
• Tracking Method: Maximum power point tracking
• Listed Efficiency: ≥99.5%; verify model
• Protection Reference: Confirm overvoltage, reverse-polarity and battery functions.
• Listed Charge Current: 30 A is a component reference, not proof of suitability for a complete 50 kW system.

Optional Energy Storage:

• Gel Lead-Acid Storage: Confirm usable energy, charge settings, ventilation and service access. Sealed batteries still require inspection and suitable operating conditions.
• LiFePO4 Storage: Confirm battery capacity, BMS integration and temperature limits. The 2,000-cycle reference depends on test conditions and is not a complete storage specification.

Project Requirements

Load Applications:

• Commercial Buildings: Size the system around the daytime demand, available installation area and electrical connection.
• Pumping Loads: Include motor starting current, daily operating hours and water-demand profile.
• Remote Facilities: Specify off-grid or backup operation separately, including storage and any alternative supply.

Installation and Service:

• Site Installation: Arrange a project-specific electrical and mounting design, qualified installation and commissioning. Confirm roof or ground constraints and the agreed responsibilities before delivery.
• Routine Maintenance: Plan panel cleaning, connection checks, monitoring and any battery servicing according to the component manuals.

Energy Performance:

• Generation Estimate: Estimate annual output from location, orientation, shading and equipment performance, then compare it with the site load profile.
• Self-Consumption: Match generation and storage operation to the load. Confirm export arrangements and backup requirements in the final system design.

A Namkoo 50 kW commercial solar enquiry starts with the site load profile and available roof or ground area. Confirm the intended capacity basis, connection mode and output requirements, then select the PV array, inverter and optional storage as a coordinated system. Request a project-specific bill of materials rather than relying on generic component examples.

  

System Scope

Solar panels produce DC electricity, while the selected inverter supplies the required AC output or grid interface. Storage and backup operation are separate options that require suitable equipment and controls. The quotation should identify panel count, inverter capacity, mounting, protection and installation responsibilities for your site.

Configuration Notes:

1. PV Module Selection: Compare rated output, module dimensions, temperature characteristics and warranty conditions. Check the array layout for shading, access and structural loading before confirming panel quantity.

2. Inverter and Grid Interface: Match input limits, output voltage and phase to the array and site supply. Confirm monitoring, export control and applicable connection requirements for the selected model.

3. Optional Battery Storage: Specify usable energy and backup loads if storage is required. Battery chemistry, power limits, BMS compatibility and operating temperature must match the inverter and control design.

4. Performance and Cost Review: Use an annual generation estimate and measured consumption data to assess self-consumption and operating costs. Include installation, maintenance and any storage replacement assumptions in the comparison.

1. Planning a 50 kW Commercial System 

1) Identify the commercial load and available installation area.

2) Match PV generation to the daily consumption profile.

3) Backup during a grid outage requires compatible storage, inverter and transfer equipment; confirm scope.

4) For pumping loads, provide motor rating, starting demand and daily operating hours.

5) Include essential lighting and control loads in the electrical schedule.

6) For remote communications or other continuous loads, specify uptime requirements and reserve duration. Size storage and any alternative supply using the low-sun season, and confirm monitoring and maintenance access.

2. Component Examples

Confirm the supplied models and quantities in the quotation.
