Practical Tips for Usage
- Sum simultaneous loads and keep them below your system's conservative (PF 0.8) limit.
- Use batteries to run loads at night or to help start high-surge appliances.
- Run heavier appliances (AC, microwave, kettle, oven) during peak sun hours.
- Check your inverter's surge rating for fridges, pumps, and compressors.
Summary
1.5kVA is for essential loads. 3.5–4.2kVA handle small to medium households with occasional heavy use. 5.2–6.2kVA can run larger homes with multiple heavy appliances, and even allow for partial EV charging.
