|
ROGERELE PU3000 is a 3000W bidirectional inverter PCBA with AC battery charging for OEM energy storage equipment. It converts battery DC into pure sine wave AC and converts an AC supply into DC to charge the battery. Separate 12V, 24V and 48V versions have listed charging currents of 50A, 30A and 15A respectively. Confirm the AC charging input, battery charging settings and inverter output configuration for your project.

Product Overview
The ROGERELE PU3000 combines pure sine wave inverter output and AC battery charging on a bidirectional PCBA for OEM energy storage systems. The inverter stage is rated at 3000W, with 6000W listed peak output; peak duration is not specified. The AC charging stage charges a matched battery pack, with catalog current of 50A for 12V, 30A for 24V and 15A for 48V versions. Review charging voltage, charging profile, battery limits, controls and cooling with the supplied assembly. This board can be evaluated for portable storage, off-grid battery equipment and RV auxiliary power products that require AC recharging.
01 / ENERGY STORAGE INTEGRATION
Core Features & Protections
PU3000 provides two conversion modes: 3000W rated DC-to-AC inverter output and AC-to-DC battery charging. The catalog lists pure sine wave output with THD below 3% under a linear load, low-voltage, over-voltage, overload and over-temperature protection, short-circuit indication and fuse operation for reverse polarity. Validate charging and inverter protection behavior in the complete system.
Match the bidirectional board, battery and enclosure as one system. Confirm the AC charging input requirements, battery charging settings and operating-mode controls before integration.
