The DC-to-AC ratio, also known as the Inverter Loading Ratio (ILR), is the ratio of the installed DC capacity of your solar panels to the AC power rating of your inverter. Typically, it''s beneficial to have a DC-to-AC ratio greater than 1, allowing your system to capture more energy throughout the day, even when production is below the inverter''s maximum capacity.

Thus a 9 kW PV array paired with a 7.6 kW AC inverter would have an ideal DC/AC ratio with minimal power loss. Clipping Losses and DC/AC Ratio. When the DC/AC ratio of a solar system is too high, the likelihood of the PV array producing more power than the inverter can handle is increases. In the event that the PV array outputs more energy than ...
Capacity ratings for utility-scale power stations are usually given in megawatts, which for most technologies means AC. However for solar plants this is sometimes expressed in terms of the DC peak capacity of the solar array, and sometimes the AC output deliverable to the grid. Sadly, many sources do not say which!
Solar panels might not generate enough wattage to directly power an appliance, but they can build up a higher wattage via a battery. Secondly, a battery can regulate the power going in to the appliance at a constant rate. When solar panels are charging a battery it is usually at a varying rate which could harm an appliance if not regulated ...
