HELIOS COMBO SPH3600/5000-BL 2 Overview
Figure2-6 Peak shaving
Energy shift scheduling
If the electricity price makes a big difference in the peak and valley time(In the valley time, the
electricity price of grid-connected generation is cheaper than PV array generation, in the peak time, the
electricity price of grid-connected generation is more expensive than PV array generation), user can
set the charging time and discharging time of battery by WiseEnergy(Equipped monitoring software
for PC). In the peak time, set to battery discharging mode(Except household used, the remaining energy
will be supplied for grid-connection generation.); in the valley time, set to battery charging mode to
charge battery, as shown in Figure2-7.
User not only can make full use of PV array generation, but also can use electricity price difference in
the peak and valley time properly to improve power consumption and generation strategy and save
electricity, which can provide more economic self-consumption power supply plan and get more
benefits.
Generally, in the energy shift scheduling mode, the battery capacity should be more than 3-4 times of
rated power.
