Renewable Energy DC Input Sources
Renewable energy (RE) sources (for example, 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, such as charge controllers,
diversion load controllers, and/or PV ground fault protection.
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.
Important: 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 visit our

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.
