How Much Electricity Can This 3640W Solar Kit Generate?

The solar array has a combined rated power of 3640W, calculated from eight 455W panels. Actual electricity generation depends on sunlight, season, roof or ground orientation, shading, panel temperature and system efficiency.

Sunshine Solar gives an indicative summer performance estimate of approximately 303Ah per day on a 48V system with the supplied MPPT controller. This is a manufacturer estimate rather than a guaranteed daily output.

For context, 303Ah at a nominal 48V represents approximately 14.5kWh of DC energy before accounting for conversion losses and other system consumption. Actual usable energy will vary with operating conditions and battery charging requirements.

In the UK, solar generation is typically higher during spring and summer and lower during winter. A suitable installation location and unshaded panel positioning can help improve overall performance.

Battery Storage: 48V AGM Battery Bank

The kit includes four 200Ah, 12V AGM deep-cycle sealed batteries configured in series to form a nominal 48V battery bank.

The resulting battery bank has a nominal capacity of approximately 48V, 200Ah, equivalent to around 9.6kWh of nominal stored energy.

AGM batteries are sealed, spill-resistant and designed for repeated charging and discharging. Their suitability depends on the expected energy demand, charging conditions and depth of discharge.

Not all nominal battery capacity should be treated as routinely usable energy. Actual usable capacity depends on the battery manufacturer's recommendations, discharge rate, temperature, battery condition and system losses.

The supplied battery configuration makes this kit suitable for applications that need stored energy to power equipment when solar generation is low or unavailable.

Choosing the Right 48V Pure Sine Wave Inverter

The power inverter converts the battery bank's 48V DC electricity into AC electricity for compatible appliances and equipment.

The kit offers three inverter output options, allowing you to select the capacity that best suits your expected loads.

3000W 48V Pure Sine Wave Inverter

The standard inverter option provides up to 3000W of rated AC output, subject to the inverter's operating limits. It may suit a range of everyday electrical loads in appropriately designed off-grid systems.

4000W 48V Pure Sine Wave Inverter

The optional 4000W upgrade provides greater rated output for installations with higher simultaneous power demands.

5000W 48V Pure Sine Wave Inverter

The optional 5000W upgrade offers the highest rated output of the available configurations, subject to the inverter's specifications and the battery bank's ability to supply the required current.

Pure sine wave output is suitable for many types of modern electrical equipment. However, each appliance must be checked for its rated power, starting surge, voltage and frequency requirements.

Important: The inverter's rated output is not the same as the solar panel array's rated power. Your available AC power depends on the selected inverter, battery bank, wiring, protection devices and system operating conditions..

Where Can You Use a 3640W Off-Grid Solar Kit?

Remote Homes and Off-Grid Properties

Generate renewable electricity for suitable remote properties where a grid connection is unavailable or expensive to install. System sizing should account for daily electricity consumption, winter generation and battery autonomy requirements.

Garden Offices and Home Offices

Power compatible office equipment, lighting, computers and other electrical devices in a garden office or remote workspace, provided the total demand is within the system's capacity.

Workshops and Garages

Support electrical equipment, lighting, chargers and other suitable workshop loads. Check motor starting currents and the continuous and surge ratings of the selected inverter before connecting power tools or machinery.

Summer Houses and Garden Buildings

Create an independent power supply for lighting, entertainment equipment, small appliances and other compatible loads in a summer house or garden building.

Static Caravans and Stables

Provide off-grid electricity for suitable lighting, appliances and equipment in static caravans, stables and outbuildings. Ensure the installation complies with the electrical requirements of the property and intended use.

Is a 3640W Off-Grid Solar Kit Right for Your Property?

This kit is designed for applications requiring a substantial solar array and a 48V battery storage system.

Before purchasing, consider:

• Your average daily electricity consumption in kWh
• The highest expected simultaneous appliance load
• The starting surge required by motors, pumps and compressors
• The amount of usable battery storage required overnight
• The available roof or ground space for eight solar panels
• Seasonal differences in UK solar generation
• Whether a backup generator or alternative charging source is required
• The inverter output needed for your appliances

A 3640W solar array does not guarantee 3640W of continuous output throughout the day. Generation varies with weather, sunlight and installation conditions. Likewise, the selected inverter determines the maximum AC output available at a given time.

If your property has high winter energy demand or needs several days of autonomy without sunlight, additional generation, battery capacity or backup power may be necessary.
