What size inverter should I use for a 9kW solar panel
Most solar professionals recommend sizing your inverter for solar panels between 75% and 115% of your total panel wattage, with the sweet spot around 1:1. This means your inverter doesn't need to power your entire home—it just converts whatever your panels generate. Your inverter needs to handle that. The DC:AC ratio (also called the inverter loading ratio or ILR) is the ratio of your solar array's DC capacity to your inverter's AC output rating: DC:AC Ratio = Total panel DC watts ÷ Inverter AC output watts Example: 6,000W of panels ÷ 5,000W inverter = 1. Undersizing means tripped breakers and failed startups. Getting the size right means the difference between 95% efficiency and 70% efficiency, which translates to hundreds of dollars in lost energy production every. Your solar inverter should match your solar array's peak panel wattage, and a solar array sizing calculator helps, so 6 kW pairs with 6,000 watts.
