Application value of Solar Energy Storage
New energy integration
To realize the reasonable allocation of wind, solar and other new
energy, solar electricity battery storage, energy storage battery
and power grid.
Uninterruptible power supply
Mobile energy storage can operate in on-grid or off-grid to ensure
uninterruptible power supply for key loads.
Price difference between peak and valley
Lithium can benefit from the price difference between peak and
valley.
Improving power quality
Solar energy storage devices improve power factor, reduce voltage
and current harmonics, adjust three-phase imbalance.
Safe and reliable
High-quality li-ion cell; Intelligent air cooling design, long
service life;
