Once we worked out the initial bugs, our Sonnen eco 16 is working great with our solar PV system. It maximizes our autonomy in that it minimizes what what we have to purchase from the grid, but with net metering doesn't really save any $. In fact the increased autonomy (70-90% as compared to 10-30% without the battery) comes at an average$10/month lower net metering credit as the energy that would be going back to the grid for credit is charging/discharging the battery. It provides backup if necessary along with our PV system (using it every day in Self Consumption mode to power our house over night, thus much better than a traditional propane or natural gas generator that requires annual maintenance, makes a lot of noise and gets used maybe a couple of times a year). Only dissatisfaction is we'd like Sonnen to allow us to change operating mode (Self Consumption to Backup) while traveling and/or integrate the weather alert feature of the new ecolinx so that the battery is fully charged when impending outage risks are high.
