Solar First Transfer Switch

by MySite Energy

This Service Entrance rated 200A transfer switch provides solar-first power to loads, with automatic switching to utility power when battery voltage becomes low.  Transfer voltage is adjustable using built-in digital voltmeter, that can display real-time battery voltage. Software settings are defined by user.  Battery voltage range is 6-300V.

Enables automatic switch to utility power when lithium batteries shut down.

Also enables fire personnel to switch off the utility and solar energy feeds at one location.  This is one of the few switches that ensure maximum protection to first responders.

The Intelligent Transfer Switch  monitors the battery voltage and the AC voltage coming from the solar system. Excessive drop in battery voltage OR loss of AC power, will cause transfer to the incoming utility power.

The utility supply your home is maintained until the battery voltage returns  AND the solar AC power resumes.  When the solar system output resumes, the transfer switch automatically switches from utility power, back to the solar power.
