These battery backup systems are line interactive which means that while
the power from the utility company is on, the system stays in stand-by
mode. When the system is in standby mode, the utility power keep the
batteries charged and transfers power to the unit. As soon as the battery
backup system senses a loss of utility power, it transfers over to the
systems' batteries. Once utility power is restored the system automatic
recharges the batteries and feeds it back thru to the unit it is supporting.
Our systems are custom and sized to meet the desired run-time and
support the specific appliance that needs to be supported. This enable us
to offer 8, 12, 16, 24, 36, and sometimes 48 hour backup run-times.
Contact our team and have them size a system that will support your specific
appliance for the run-time you desire.
