Energy Storage Systems

Low-frequency and high-frequency pure sine wave topologies rated from 1kW to 15kW, featuring toroidal transformer isolation, peak surge capacity, and integrated ATS switching.

High-voltage tracking algorithms delivering 99.5% conversion efficiency across 12V to 96V battery banks, packaged in die-cast aluminum heat sinks for passive convective cooling.

Integrated lithium iron phosphate battery enclosures with built-in inverter modules, modular stackable footprints, and multi-protocol CAN and RS485 communication interfaces.

Direct Engineering

Direct Factory Engineering Accountability

We machine our own heat sinks, assemble automated SMT surface-mount boards, and verify every completed unit through thermal stress cycles before container loading.
