The Heart of a Sophisticated, Independent Power System
Your PROsine has been designed to be the heart of a sophisticated, independent
power system. While the PROsine is an extremely “friendly” product to operate,
Xantrex wants to ensure that you get the best performance from your system. So
please take a few minutes to read the next few pages: they’ll give you an excellent
understanding of the PROsine’s features and capabilities.
In basic terms, the PROsine is designed to:
p Invert
p Charge
p Manage your power system
Inverting
The PROsine’s inverting function:
p Produces 120Vac from your 12V batteries
p Delivers 2kW of power on a continuous basis and 4.5kW of surge power to
start heavy loads like air conditioners, fridges, and pumps
Much of the time the inverter may not be powering loads. During these times, you
don’t want power to be drawn needlessly from the batteries. To reduce idle current
to an absolute minimum, Xantrex has included three features:
p Low standby battery demand
p Load sense (search) mode
p Remote Shutdown
Low Standby
Battery Demand
When the PROsine is inverting (producing 120Vac output without a load), it
draws less than 2A of current from the batteries.
Load Sense
(Search) Mode
To reduce battery draw even further, you can turn on Load Sense mode. In Load
Sense mode, the PROsine periodically sends out a search pulse to see whether a
load is present. If it finds a load, it will turn on. You can adjust the interval
between search pulses, and you can also adjust the load power at which the
PROsine will turn on.
Note that in Load Sense mode, there’s a short time delay (up to the interval you’ve
set) between the time you turn on a load and the time the PROsine delivers power.
Of course, you can disable Load Sense mode at any time if you find the delay
inconvenient.
