The Exeltech BBS is an
integrated inverter/charger system with
transfer switch. Several key features allow
the Exeltech BBS to stand out among other
battery backup systems. It is designed to
provide backup power for critical LED
traffic light intersections. With 1,000
watts of true sinewave power available,
the Exeltech BBS will drive most large LED
systems. Its pure sinewave output is cleaner
than utility power, making it ideal for all
loads. Total distortion is typically less
than 1.5%. Manufactured in the USA to the
highest standards possible, Exeltech's BBS
system is the best choice for critical load
protection.
