Installing a renewable energy power system for a customer without including an entire-system, net (both total power made and used) metering system is like selling a car or boat or airplane with no gas gauge.
And if the installer can lock out any changes to the meter's data acquisition of absolute minimum values (SOC and time, battery voltage and time, etc.) with a password, so much the better! "Umm, you say you've always kept the battery bank charged, but I show you were at 11.2 volts for the last 7 months?"
