The PB series wall-mounted energy storage battery system begins by converting sunlight into direct current (DC) through solar panels, which is then fed to a hybrid inverter. The inverter efficiently converts the DC to alternating current (AC) to power your home, prioritizing solar power for on-demand supply. Any excess energy can be stored in the battery (if equipped) or fed back to the grid via a bidirectional meter. When solar power is insufficient, the system seamlessly draws power from either the battery or the grid to ensure uninterrupted power supply. Users can monitor and manage the entire system in real time via a web or mobile application, with support from BST cloud data services. The system can be used for both grid-connected and off-grid operation, providing modern homes with energy independence, cost savings, and reliable, intelligent energy management.
