Solar Sizing & Load Calculator
Selecting the wrong solar setup can cause frequent power cut-offs or damage to batteries. Use our sizing recommendations to choose the right capacity for your home or business.
Typical Load Configurations
| System Size | Typical Appliances Powered | Recommended Battery | Recommended Panels |
|---|---|---|---|
| 1.5kVA / 12V | 1 TV, 4 LED bulbs, 2 Standing Fans, Laptops | 1x 200Ah Gel / 1x 100Ah Lithium | 2x 450W Monocrystalline |
| 3.5kVA / 24V | 2 TVs, Fridge, Freezer, Fans, Bulbs, Sound System | 2x 200Ah Gel / 1x 200Ah 24V Lithium | 4x 550W Monocrystalline |
| 5.0kVA / 48V | Full House + 1HP Inverter AC, Washing Machine | 4x 200Ah Gel / 1x 5kWh 48V Lithium | 6x 550W Bifacial Panels |
| 10.0kVA / 48V | Duplex with 2-3 ACs, Pumping Machine, Refrigerators | 2x 10kWh Lithium Rack | 12x 600W Panels |
Step-by-Step Load Calculation
List Essential Appliances
Write down all appliances you plan to run simultaneously on solar power.
Check Wattage Ratings
Locate the wattage label on the back of each appliance (e.g. Standing Fan = 55W, 55" Smart TV = 110W, Inverter AC = 800W).
Add Surge Allowance
Motorized appliances (refrigerators, pumps, air conditioners) require 3x surge power upon startup. Ensure your inverter kVA rating handles the peak surge.
Pro Tip: Upgrading your appliances to energy-efficient inverter-based models can reduce your required battery investment by up to 40%!
