Invert Function
The PRO-Verter’s Invert function transforms DC from a connected battery into pure sine-wave AC
power for an AC load. When 24 volts DC is available from a connected battery, the PRO-Verter
automatically engages its inverter circuit functions, and AC power is immediately available for the
load. The inverter (“INV”) LED indicator at the User Interface will be steady-on when AC power is
available, while inverting, or in standby.
When AC power is available from a grid-utility or generator source, the PRO-Verter is programmed
to defer the load (via the transfer switch) onto the external source, which will cause the inverter
circuit to go into “standby” mode (green INV LED remains on). In standby mode, the inverter circuit
is not actively providing power from the batteries to the loads, rather, the loads connected to the
inverter are powered directly using the external AC power (pass-through power). However, if power
from the external AC source is interrupted, the inverter senses these conditions and immediately
starts inverting to maintain AC output to the loads.
Only a manual deactivation of the inverter function will cause the LED to turn off. If the inverter
function is not engaged, then AC power will only be available when the PRO-Verter is connected to
an active AC source, and it is passing power through to the AC load.
It is recommended that this
function always remain on
.
The inverter circuit has extensive protection circuitry to shut down the inverter under certain fault
conditions. The red FAULT LED will be steady-on and the associated error message will be shown
on the LCD.
Automatic Generator Start/Stop (AGS) Function
The AGS circuit is used to start/stop an external generator, controlling it based on AGS
programming that is made for the application in which the PRO-Verter is being used.
Generator function can be triggered by singular or multiple conditions, including:
• Battery state-of-charge (SOC)
• Time of day
• Peak shaving
• Quiet time
