How Many Batteries Do You Need for a 5kva Inverter in Zimbabwe?

Sona Solar Zimbabwe is here to illuminate your path to solar power! Many considering solar energy systems wonder how many batteries are needed for a 5kva inverterThe answer, like sunshine, isn't one-size-fits-all. It depends on several crucial factors:

Understanding Your Power Needs

  1. Daily Energy Consumption: The key element is your daily electricity usage in kilowatt-hours (kWh). Appliance ratings and usage patterns will determine this. Your electricity bill can provide historical usage data or Sona Solar Zimbabwe can help you estimate it.
  2. Desired Backup Time: How long do you want your system to power your appliances during a power outage? 2 hours? 4 hours? The longer the backup time, the more battery capacity you'll need.

Battery Capacity and Efficiency

  1. Battery Amp-hours (Ah): This indicates the total current a battery can deliver over a specific time. For example, a 100Ah battery can deliver 1 amp for 100 hours or 5 amps for 20 hours.
  2. Depth of Discharge (DoD): LiFePO4 batteries, the recommended choice for solar systems due to their safety and lifespan, typically have a DoD of around 80%. This means you should only discharge them to 80% of their capacity to maximize their lifespan. So, a 100Ah battery would have a usable capacity of 80Ah (100Ah x 80% DoD).

Calculating Battery Requirements

Here's a simplified formula to estimate the number of batteries you'll need:

Number of Batteries = (Daily Energy Consumption in kWh x Backup Time in hours) / (Usable Battery Capacity in Ah x Inverter Voltage)


Let's say your home uses 5kWh per day and you want a 2-hour backup with a 5kva inverter (typically 48V). We'll assume you're using 100Ah LiFePO4 batteries.
  • Usable Capacity per Battery: 100Ah x 80% DoD = 80Ah
  • Required Capacity: 5kWh x 2 hours = 10kWh

Number of Batteries = 10kWh / (80Ah x 48V) = 2.6

Since you can't have a fraction of a battery, you'll need to round up to 3 batteries.

Important Considerations

  1. This is an estimate: Adjust for inefficiencies in the inverter and real-world conditions.
  2. Consult Sona Solar Zimbabwe's Experts: They can conduct a thorough site assessment and calculate your specific battery requirements for optimal performance.
  3. Solar System Design: The number of solar panels you install will also impact how much energy your batteries store. Sona Solar Zimbabwe will design a system that meets your needs.
