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, gerbėjų, or phone chargers. Kitas, estimate how many hours you use each appliance daily.

Žingsnis 1: List the Appliances You Use

Write down the appliances you want the battery to power.

Pavyzdžiui:

• 20 LED lemputės
• One 43-inch TV
• One refrigerator
• Phone chargers
• A fan

Žingsnis 2: Estimate Daily Usage Hours

Kitas, estimate how many hours you use each appliance every day.

Pavyzdys:

• Security lights: 12 valandų
• Indoor lights: 5 valandų
• televizorius: 12 valandų
• Šaldytuvas: Runs automatically throughout the day
• Phone charging: 2–3 hours

You don’t need exact numbers. A reasonable estimate is enough.

Žingsnis 3: Calculate Daily Energy Consumption

Use this simple formula:

Galia (Vatai) × Hours ÷ 1000 = Energija (kWh)

Pavyzdys:

Total daily energy use is approximately 2.8–3.0 kWh.

Žingsnis 4: Match Your Daily Usage to the Right Battery

A simple guide:

• Iki 2 kWh/dieną → 2.56 kWh baterija
• 2–4 kWh/day → 5.12 kWh baterija

• 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 valandų
• 43-inch TCL TV for around 12 valandų
• One refrigerator

After calculating the daily energy usage, the total was about 3 kWh per day.

The recommended solution was:

• 3.6kW hibridinis keitiklis
• 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?

Palyginti su tradiciniais švino rūgšties akumuliatoriais, LiFePO₄ batteries offer:

• More than 6,000 charge cycles
• Ilgesnis tarnavimo laikas
• Faster charging
• Higher efficiency
• Lower maintenance
• Better safety

Although the initial investment is higher, the lifetime cost is often much lower.
