Product overview:
The integrated power supply of solar storage and charging is a device used in PV power generation system to realize DC/AC power conversion. Using power electronic control technology, it can coordinate and control the output of PV and energy storage cells, stabilize the power fluctuation of PV cells, and output AC power that meets the standard requirements to supply power to the load through energy storage and conversion technology. The equipment has such functions and features as dynamic adjustment of working mode, switching of grid connection mode, high power tracking of PV energy, and fine management of energy storage batteries, which can be widely used in off grid PV power stations, distributed backup power supplies, energy storage stations, etc.
The integrated optical storage and charging power supply adopts the four quadrant converter technology to realize the bidirectional flow of energy between the AC system and the DC system; The equipment integrates the PV convergence function and supports the charge and discharge management of the energy storage battery; The AC side adopts voltage oriented vector control strategy; The system has the functions of adjustable input and output power factor, automatic soft start and PV energy high-power tracking.
Basic control functions: grid connected constant power charging and discharging control Off grid V/F control Reactive power regulation control Low voltage side MPPT control Compatible with various types of PV and energy storage batteries Grid connected - off grid smooth switching control Anti islanding protection function and islanding detection Mode switching function Fault through control function.
