Renewable Energy DC Input Sources
Renewable energy sources (e.g., photovoltaic (PV) arrays, wind turbines,
DC micro-hydro generators) can be used with the inverter to provide
power for all applications—off grid and on grid. However, in addition to
the actual RE equipment being used, other items may be needed to ensure
safety in the overall system.
Charge Regulation
using a Charge
Controller A charge controller must be used to regulate the charge supplied to the
batteries and prevents over-charging (or high battery conditions). A
charge controller prevents the batteries from exceeding a user-specified
voltage level. This preserves and extends the life of the battery by
preventing the damage caused by over-charging. The charge controller
can also take over the functions of bulk and equalize charging.
Diversion Load
Control Wind turbines and hydro-electric generators may be damaged if the DC
loads are suddenly removed from them. This can happen if the DC
disconnect should open (trip) or the batteries are fully charged and no
other DC loads are connected in the system. A diversion load controller
prevents damage to the generator system by diverting the power from the
generator to a diversion load device. This keeps a load on the generator
and controls over-spin if the batteries should be disconnected. Refer to
the controller manual for proper types of diversion load devices.
Important:
Be sure to consult your authorized dealer and all local/
national electric codes to determine what additional equipment may be
required for your installation.
Installations of this equipment should only be performed by skilled
personnel such as qualified electricians and Certified Renewable Energy
(RE) System Installers. For a list of Xantrex Certified RE dealers, please

Note: The “charger” built into the Sine Wave Plus is only for AC
power connected to either of the AC inputs on the inverter/charger. The
Sine Wave Plus cannot control or regulate DC voltages from DC
sources. DC charge controllers must be used for all DC sources such as
PV arrays, wind turbines, and water turbines.
