Kweli Energy 1.8kWp-5kWh-4kVA Complete Smart Hybrid Solar Power System

The Kweli Energy 1.8kWp-5kWh-4kVA Complete Smart Hybrid Solar Power System provides dependable day and night electricity for homes, offices, shops and small businesses.

During the day, the 1.8kWp solar array powers connected appliances and charges the 5kWh lithium battery. At night, during cloudy periods or whenever grid electricity is unavailable, stored battery energy keeps essential appliances operating.

The 4kVA pure sine wave hybrid inverter automatically manages energy from solar, the battery, the grid and a compatible generator. This allows the system to switch between available power sources without requiring manual intervention.

WiFi app monitoring provides remote visibility of solar production, battery status, energy consumption and overall system performance.

With an estimated solar yield of 6-8kWh per day under suitable conditions, the system can reduce dependence on the grid, lower generator fuel consumption and provide more consistent electricity for essential loads.

What This System Can Power

The system can support a practical combination of essential appliances such as:

• LED lights
• Television and decoder
• Energy-efficient refrigerator
• WiFi router
• Laptops and phone chargers
• Desktop computer
• Fans
• CCTV system
• Printer
• Sound system
• Small office equipment
• Other low-to-medium-power appliances

The appliances that can run simultaneously and their operating time depend on their wattage, starting surge, daily usage and the battery charge available.

High-power heating appliances should not be assumed to operate together with the recommended essential loads.

Overall System

Solar Array

Actual solar production depends on weather, sunlight hours, shading, panel orientation, temperature, installation angle and system losses.

Lithium Battery

Usable battery energy may be lower than the nominal 5kWh capacity depending on the configured depth of discharge, battery-protection settings, operating temperature and conversion losses.

Hybrid Inverter

Monitoring and Control

How the System Works

1. Solar energy powers connected appliances during the day.
2. Available excess solar energy charges the lithium battery.
3. The battery supplies stored electricity at night or during outages.
4. The system automatically uses grid or generator power when solar and battery energy are insufficient.
5. When solar or battery energy becomes available again, the inverter follows the configured source priority.
6. WiFi app monitoring provides remote visibility of system production and performance.

Understanding the System Ratings

1.8kWp Solar Array

This is the combined rated power of the solar panels. It determines how much solar power the system can produce at a given moment under suitable sunlight.

6-8kWh Daily Solar Yield

This is the estimated amount of solar energy the panels can generate during a suitable day. Actual production varies with weather and installation conditions.

5kWh Lithium Battery

This is the battery’s nominal energy-storage capacity. It determines how much energy can be stored for use at night, during cloudy periods or during power outages.

4kVA Hybrid Inverter

This is the inverter’s rated apparent-power capacity. It determines the maximum combined appliance load that the system can support at one time, subject to power factor and appliance starting surge.

• Combined appliance load: The total appliances operating at the same time must remain within the inverter’s supported continuous and surge capacity.
• Battery runtime: Backup duration depends on the total connected load. Lower consumption provides longer battery autonomy.
• Daily energy demand: The estimated 6-8kWh solar yield should be compared with the property’s actual daily electricity consumption.
• Refrigerator starting surge: Refrigerators, pumps and other motor-driven appliances can briefly require more power when starting.
• High-power appliances: Electric cookers, kettles, water heaters, air conditioners, large pumps, welding machines and similar appliances may require a larger system or controlled operation.
• Site conditions: Solar production depends on panel orientation, installation angle, roof space, shading and local weather.
• WiFi availability: Remote app monitoring requires a reliable WiFi internet connection at the installation site.
• Generator quality: A connected generator must provide voltage, frequency and power quality compatible with the inverter.
• Installation cost: Installation is charged separately and depends on the roof, mounting method, cable distances, distribution requirements, protection and earthing.
