Voltage Installed: 5kw

1. Solar Power Generation Total solar capacity = 12 × 590W = 7.08kW Daily solar energy output (assuming 5 peak sun hours) = 7.08kW × 5h = ~35kWh/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 Total Estimated Daily Usage = ~10-12kWh 3. Battery Storage & Backup Your 20kWh BYD battery can power all loads for 1.5 to 2 days if solar is unavailable. During nighttime, the battery will supply power. 4. Inverter Capacity (5kW Raion) The 5kW inverter is sufficient for running most appliances, but high-power devices should not be used simultaneously. Washing machine (1kW) + booster pump (500W) + fridge/freezer (300W) = ~1.8kW, well within the 5kW limit. If the dishwasher (1.5kW) is added, the total could reach 3.3kW–4kW, which is still manageable. Is This System Sufficient? ✅ Yes, it is! Your solar system can generate ~35kWh/day, which is far more than your estimated daily usage (~12kWh). This ensures: Daytime loads run directly on solar power. Excess solar power charges the battery. Enough battery backup for nighttime use. Recommendations for Best Performance Run high-power appliances (washing machine, booster pump) during the day to use direct solar power. Avoid running too many appliances together to stay within the 5kW inverter limit. Ensure the battery fully charges daily by keeping solar panels clean and ensuring proper sunlight exposure.
