PV MPPT and grid-tie current, PCS and BMS bus current in storage systems, and charge/discharge sensing for portable power — covering generation, conversion and storage.
Renewable Energy & Storage
Efficiency and safety in PV and storage systems both rest on current measurement: MPPT tracks the optimum from input current, grid-tie control governs output current phase and amplitude, and the BMS integrates bus current to estimate SOC. Any shortfall in accuracy shows up directly in yield or battery life.
RJMICRO Hall current sensors provide isolated current sensing suited to high common-mode positions such as PV strings, the DC side of a PCS and battery clusters, while low-quiescent-current LDOs supply auxiliary rails and communication modules.
