Kweli Energy 900Wp-2.56kWh-1.5kVA Hybrid Solar Power System

The Kweli Energy 900Wp-2.56kWh-1.5kVA Complete Hybrid Solar Power System provides dependable day and night electricity for small homes, apartments, offices, shops and other low-consumption applications.

During the day, the 900Wp solar array powers connected appliances while charging the SRNE EOS02B-12 2.56kWh lithium battery. Stored battery energy can then be used after sunset, during cloudy periods or whenever grid electricity is unavailable.

The SRNE HF1215S60-108 hybrid inverter delivers up to 1.5kW of continuous pure sine wave power and automatically manages energy from solar, the battery, the grid and a compatible generator. Automatic switchover means essential appliances can continue operating without requiring manual source changes.

With an estimated solar yield of 3.5-4.5kWh per day under suitable conditions, this system is ideal for customers who need reliable essential power without investing in an unnecessarily large solar installation.

What This System Can Power

The system can support a carefully managed combination of appliances such as:

• LED lights
• Television and decoder
• WiFi router
• Laptops and mobile-device chargers
• CCTV cameras and recorder
• Fans
• Small sound system
• Small office electronics
• Energy-efficient refrigerator, subject to starting-surge assessment

The total connected load should remain within the inverter’s 1,500W continuous output capacity.

Actual operating time depends on the number of appliances connected, their power consumption, battery charge level and whether solar power is available.

Appliances Not Recommended

This system is not intended for regular operation of high-consumption appliances such as:

• Electric kettles
• Electric cookers
• Flat irons
• Microwave ovens
• Water heaters
• Air conditioners
• Welding machines
• Large water pumps
• Large freezers
• Heavy workshop equipment

These appliances may exceed the inverter capacity or discharge the battery very quickly.

Main Equipment

SRNE EOS02B-12 Lithium Battery

The included SRNE battery provides 2.56kWh of nominal energy storage from a 12.8V, 200Ah LiFePO4 battery platform. It is rated for over 6,000 cycles at the recommended 80% depth of discharge under specified operating conditions.

The integrated battery management system protects the cells and supports communication through CAN, RS485 and USB.

SRNE HF1215S60-108 Hybrid Inverter

The SRNE inverter delivers 1.5kVA/1.5kW continuous pure sine wave output, with up to 3,000VA peak capacity for brief appliance starting surges.

It includes a built-in 60A MPPT solar charge controller, automatic source selection and grid or compatible generator charging support.

900Wp Solar Array

The installed 900Wp solar array is designed to generate approximately 3.5-4.5kWh of energy per day under suitable sunlight, panel positioning and weather conditions.

Solar energy is used to operate daytime loads and charge the lithium battery.

Best For

• Small homes requiring essential backup electricity
• Apartments with modest electricity consumption
• Shops requiring lighting, CCTV and payment equipment
• Offices using laptops, routers and low-power electronics
• Customers experiencing regular grid outages
• Customers seeking to reduce daytime grid consumption
• Locations requiring automatic backup power
• Customers upgrading from small lead-acid backup systems

Estimated Battery Capacity

At the recommended 80% depth of discharge, the 2.56kWh battery provides approximately 2.05kWh of nominal usable stored energy before inverter, cable and other system losses.

Indicative battery-only runtime may include:

These estimates are indicative only. Actual runtime depends on battery condition, inverter efficiency, appliance behaviour, operating temperature and available solar input.

• Maximum appliance load: The combined operating load should remain within the inverter’s 1,500W continuous output capacity.
• Battery runtime: Backup duration depends on the total connected load. Lower consumption provides longer operating time.
• Daily electricity use: Compare the estimated 3.5-4.5kWh solar yield with your expected daily energy consumption.
• Motor starting surge: Refrigerators, fans and pumps may briefly require more power when starting.
• Heavy appliances: Kettles, cookers, irons, air conditioners, water heaters and workshop equipment require a larger system.
• Solar conditions: Daily production depends on sunlight, shading, panel orientation, roof angle, temperature and weather.
• Installation environment: The inverter and battery should be installed in a dry, ventilated and protected indoor location.
• Remote monitoring: WiFi or GPRS monitoring is optional and is included only when stated in the quotation.
• Future expansion: Customers planning to add more appliances may need a larger inverter, battery or solar array.
