SmartRoof Capital - Profile & Reviews

My implemented system includes 30 (Hanwa) panels, the Generac 7.6 inverter and the Generac battery. Panels seemed the simplest to install. I wanted a failsafe design where solar failed over to the battery. In the end I needed an NG generator should the grid go down. Despite going with Generac as the systems vendor there is not interconnection between devices to provide seamless service. Generac would be well served to fix this as they have all the components to allow positive net-metering and fail-safe off-grid backup power it is just that these systems do not speak to each other and in fact the NG (backup) generator triggers via an analog switch in front of your electrical panel. The generator is completely un aware of your PV system and vis-a-versa. During a power failure your NG generator triggers and you cannot use your PV connected battery. It should operate in reverse, your PV connected battery (if exists) should operate immediately and at some setting (I.e. 25%) trigger the NG generator). Power failures are usually brief and thus the generator would be for long-term events only.

SmartRoof worked hard to provide constant customer service, but systems integration took some time. Now that the the PV is connected to the grid it is producing at higher than expected daily numbers.
