🏠 Electrical Loads

Appliance / Equipment Quantity Power Rating Usage (hrs) / Day Total Watts

TR Formula: Equivalent Watts = (TR × 3516.85 W) ÷ COP.

Sum of Electrical Loads 0.00 W Total of all Quantity × Power Rating values.
30% Buffer 0.00 W Additional allowance equal to Sum of Load × 0.30.
Total Load with 30% Buffer 0.00 W Recommended design basis: Sum of Load × 1.30.

Note: Select W, hp, or TR in the Power Rating column. If hp is selected, it is automatically converted in Watts using 1 hp = 745.7 W. If TR is selected, the equivalent wattage is computed as (TR × 3516.85 W) ÷ selected COP. The summary above automatically displays the total electrical load, 30% buffer, and total load with buffer.
Slide the table horizontally on mobile devices to view all columns.

🔋 Battery Sizing

Battery Voltage 48.00 V Selected battery bank voltage.
Required Capacity 0.00 Ah Ah = Required Wh ÷ Battery Voltage.
Required Energy 0.00 kWh kWh = Total load with 30% buffer × autonomy hours ÷ 1000.

Battery sizing formula: Required Energy, kWh = Total Load with 30% Buffer × Autonomy Hours ÷ 1000. Required Capacity, Ah = Required Energy, Wh ÷ Battery Voltage. This is a preliminary sizing guide only; final sizing may still consider inverter efficiency, battery depth of discharge, battery chemistry, aging factor, and site-specific requirements.
