Integrated inverter-storage system supercharges solar installations, combining energy management software with storage to maximize on-site consumption.
According to the SMA website, the battery storage, with the home energy management software that optimizes use of solar production and the battery, can increase self-consumption from 30% to 55% of production based on German production and consumption parameters (including 5,000 annual kWh of consumption and solar production). In different situations where production and consumption are more correlated (air conditioning load, Australia), the results could be different or require more storage.
Still, it is interesting that a small amount of storage (2 kWh) can have a big impact. Australia does not have net metering and power fed back into the grid is now paid a relatively low price. If this advances fast enough, in the U.S. it could really blunt any pain that occurs when net metering goes away as well as represent a further reduction in utility sales.
