Choose with the
whole day in mind.

Build a daily energy picture

List each appliance, its rated input power and the hours it operates. Energy in kWh equals appliance power in kW multiplied by operating hours. Add the loads that will actually run together. Include standby consumption and ask an installer to account for system losses, seasonal conditions and reserve capacity.

Separate energy from power

Daily energy describes how much electricity you use over time. Maximum output describes the loads the system can serve at once. A battery capacity alone cannot establish whether a pump or refrigerator will start. Confirm continuous output, starting demand and the limits of each inverter.

Define the backup window

Identify essential circuits and their expected operating hours during an interruption. Usable battery energy depends on discharge limits, conversion losses and operating conditions. Do not treat the listed storage capacity as a promise of runtime. For longer interruptions, review recharge opportunities and any generator interface.

Check the space

The listed installation area is PV coverage, not a complete site layout. Leave room for maintenance, equipment, ventilation and local setbacks. Roofs, balconies, carports and fences need their own structural and electrical assessment. Check shading throughout the intended operating season.

Use the table as a shortlist

The figures below reproduce the supplied product table. Approximate daily generation is a comparison figure rather than a forecast for every African location. The ECP8K storage conflict is displayed explicitly. Send your location and load schedule for a final selection.
