PCS converts DC power supplied by batteries and photovoltaic into AC power that is integrated into the grid, which can be used in grid-connected or off-grid mode. Inverter models with STS modules can quickly switch between grid-connected and off-grid modes.
Adopt two-stage topology and wide voltage input range：250-520V；
Can be connected to photovoltaic panels；
With MPPT photovoltaic maximum power tracking function；
Photovoltaic can directly charge the battery to ensure the highest system efficiency.

NKGP -50K / 100K PCS composed of one or more groups of DC modules and AC modules. These modules identify the master-slave system through the dial code of the DIP switch on the panel. One of the modules acts as the master, and the other modules act as slaves to synchronize with the master.
The equipment is equipped with SPD protectors, AC and DC switches and auxiliary power distribution units. If you want to realize the fast on-off and off-grid switching function, you need to configure the STS module separately. Figure 3.2 and 3.3 are the topological diagrams of the two components respectively.
