OFF GRID 20KW SYSTEM: 8kW Raion inverter 20kWh BYD lithium battery 16 x 590W solar panels (total 9.44kW solar array) Appliances: fridge, freezer, washing machine, dishwasher, lights, booster pump, TV System Analysis 1. Solar Power Generation Total solar capacity = 16 × 590W = 9.44kW Daily solar energy (assuming 5 peak sun hours) = 9.44kW × 5h = 47.2kWh/day 2. Estimated Appliance Consumption Appliance Power (W) Estimated Daily Use (kWh) Fridge 150W ~1.5kWh Freezer 150W ~1.5kWh TV 100W ~0.5kWh Lights (LED) 100W ~1kWh Booster Pump 500W ~1kWh Washing Machine 1000W ~2kWh per cycle Dishwasher 1500W ~2kWh per cycle Total Estimated Daily Usage = ~10-15kWh 3. Battery Storage & Backup Your 20kWh BYD battery can fully cover 1.5–2 days of usage if solar is unavailable. At night, power will come from the battery. Is This System Sufficient? ✅ Yes! Your solar system can generate ~47kWh/day, which is far more than your estimated daily usage (~15kWh). This ensures: Daytime loads run directly on solar power. Excess solar power charges the battery. Enough backup storage for nighttime use. Recommendations for Best Performance Run high-power appliances (washing machine, dishwasher, pump) during the day to use direct solar power. Monitor peak loads to prevent overloading the inverter (e.g., avoid running multiple high-wattage appliances at once). Optimize battery charging by ensuring panels are clean and properly installed for maximum efficiency.
