• Note their rated power (in watts)
• Estimate daily usage time (in hours)

Example:

A 60 W fan used for 6 hours:

60 × 6 = 360 Wh/day

Add all appliance energy values to determine your average daily energy consumption (Wh or kWh).

👉 Design Tip:
Size your system for 120–150% of current load to account for seasonal variation and future expansion.

Step 2: Decide Required Backup Duration

Battery size is directly linked to how long you want power during grid outages.

Formula:

Battery Capacity (Wh) = Load (W) × Backup Time (hrs)

Example:

If you want to run a 1 kW load for 4 hours:

1,000 × 4 = 4,000 Wh = 4 kWh

Adjust for Usable Capacity

Lithium-ion batteries typically allow 80–90% usable Depth of Discharge (DoD).

So required battery size:

4 kWh ÷ 0.8 = 5 kWh (recommended)

Step 4: Select Battery Voltage

Battery voltage must match inverter and charge controller specifications.

👉 Why 48V is preferred:

• Higher efficiency
• Lower current & cable losses
• Better safety-to-performance balance

Step 5: Decide Number of Batteries (Corrected Example)
