How to Choose the Right Solar Battery Size in Uganda (Simple Guide for Homeowners) 2026
Many homeowners in Uganda ask the same question:
“What battery size do I need for my house?”
The answer isn’t based on how many people live in your home. It depends on how much electricity you use each day.
The good news is that you don’t need to be an electrician. With a few simple steps, you can estimate your daily energy use and choose the right LiFePO₄ battery.
How to Choose the Right Solar Battery Size
Start by listing the appliances you want to power, such as LED lights, a TV, a refrigerator, fanoušků, or phone chargers. další, estimate how many hours you use each appliance daily.

Krok 1: List the Appliances You Use
Write down the appliances you want the battery to power.
Například:
- 20 LED světla
- One 43-inch TV
- One refrigerator
- Phone chargers
- A fan
Krok 2: Estimate Daily Usage Hours
další, estimate how many hours you use each appliance every day.
Příklad:
- Security lights: 12 hodin
- Indoor lights: 5 hodin
- televize: 12 hodin
- Lednička: Runs automatically throughout the day
- Phone charging: 2–3 hours
You don’t need exact numbers. A reasonable estimate is enough.
Krok 3: Calculate Daily Energy Consumption
Use this simple formula:
Moc (Watts) × Hours ÷ 1000 = Energy (kWh)
Příklad:
| Appliance | Moc | hodiny | Daily Energy |
|---|---|---|---|
| 20 LED Lights | 200W | 5h | 1.0 kWh |
| 43″ televize | 70W | 12h | 0.84 kWh |
| Lednička | Průměrný | — | 1.0 kWh |
Total daily energy use is approximately 2.8–3.0 kWh.

Krok 4: Match Your Daily Usage to the Right Battery
A simple guide:
- Up to 2 kWh/den → 2.56 kWh baterie
- 2–4 kWh/day → 5.12 kWh baterie
- 4–7 kWh/day → 10.24 kWh baterie
- 7–12 kWh/day → 15–20 kWh battery
Choosing a slightly larger battery gives you extra backup time and allows room for future appliances.
Real Customer Example
A customer in Uganda told us:
- 6 security lights run all night
- Indoor lights for about 5 hodin
- 43-inch TCL TV for around 12 hodin
- One refrigerator
After calculating the daily energy usage, the total was about 3 kWh per day.
The recommended solution was:
- 3.6kW Hybrid Inverter
- 5.12kWh LiFePO₄ Battery
- 2–3kW Solar Panels
This setup provides reliable power during outages and can easily be expanded later.

Why Choose LiFePO₄ Batteries?
Compared with traditional lead-acid batteries, LiFePO₄ batteries offer:
- Více než 6,000 charge cycles
- Longer service life
- Faster charging
- Higher efficiency
- Lower maintenance
- Better safety
Although the initial investment is higher, the lifetime cost is often much lower.
