Load Prioritization
When the AES is fully functioning, providing power to the load is always prioritized over other
functions.
If renewable DC generators (i.e., PV arrays, wind, etc.) are producing power, it is immediately
directed to to the load once it flows into the AES. The batteries will begin to charge ONLY when the
DC generation exceeds the demand from the load.
During periods of peak renewable DC power production, it may be exclusively used to support the
load while excess energy charges the batteries simultaneously. This function reduces the demand on
the batteries, prolongs battery operation time, and promotes healthy cycling of the battery.
This same function also occurs when the AES is connected to an AC source. If the AES is connected
to an active generator or grid utility, the load is always supported FIRST before any AC is used
for charging the AES batteries. If the PRO-Verter is controlling a connected generator and the
battery bank reaches a low state-of-charge, the PRO-Verter can be programmed to auto-start the
generator to keep AC flowing to the load, charging the connected batteries only after the load is fully
supported by the generator.
Real-time Load Management
When connected to an active AC source, the PRO-Verter can automatically adjust (in real time) its
battery charging rate to keep the total load value under the AC Input setting value.
If the load is dynamic, the PRO-Verter can make immediate adjustments and keep the total load on
the AC source from exceeding the value of the AC Input setting while still maintaining a 100% load
at the external AC source (generator or grid utility).
It is incumbent on the Operator to ensure the sum of all loads does not exceed the limit of the AC
source (generator or grid utility) or the connections or circuit protections in the network. The AC
Input (FAVS 03) setting should be set to the same value of the maximum AC output rating of the
source. For example, if the generator is rated for 3000 W continuous output, then the AC Input
should be set for 25 A (25 A @ 120 VAC = 3000 W).

UPS (Automatic Functions)
Operating conditions:
A PRO-Verter connects critical AC loads directly to grid utility or prime AC
power when it is available, and provides backup power for the load by supplying inverter AC (using
energy from a connected battery bank) when the grid utility or prime AC source is interrupted.
In the UPS Model, “peak shaving” and the use of renewable power sources are also possible by
connecting a Power Hub.
Note about PRO-Verter Model Programming:
The PRO-Verter is programmed at the factory for
use in the application in which it is to be used. It is possible for the Operator to alter any of the
programmed settings when operating conditions change and/or System architecture changes are
necessary. To learn more, contact Solar Stik Technical Support.
