Power & Energy
Custom wire harnesses and cable assemblies for power and energy systems — battery and energy-storage (BESS) module harnesses, solar / PV string wiring, EV-charging and inverter harnesses, BMS sense and balance leads, and high-current busbar interconnect. Engineered and 100% electrically tested in Taiwan since 1998.
What We Build For Power & Energy
Energy systems live and die on the high-current connection. For twenty-eight years we've built battery, solar, and power-conversion harnesses for energy-storage integrators, PV and inverter OEMs, and EV-charging makers — assemblies that carry serious current without losing a millivolt where it matters.
Our power and energy practice spans battery and energy-storage (BESS) module harnesses, solar / PV string wiring, EV-charging and EVSE harnesses, inverter and power-conversion looms, BMS sense and balance leads, and high-current busbar interconnect — high-voltage power and low-voltage sense on one bill of materials.
The same line in Taiwan wires all of it — from a feasibility sample to grid-scale volumes. Send a sketch, a BOM, or a competitor sample, and we return a design-for-manufacture review in three business days.

3 Product Families Do Most Of The Power & Energy Work
Battery / BESS harness
Module-to-module power links plus BMS voltage-sense and balance leads for energy-storage packs. HV-rated and hi-pot tested.
Solar / PV string harness
PV string and combiner wiring with MC4-compatible terminations, UV-stable and rated to 1500 V DC.
High-current power harness
Laminated and flexible busbar, lug and stud interconnect for EV charging, inverters and pack distribution. Calibrated-torque terminations.

Can you build high-voltage battery and BESS harnesses?
Yes. We build module-to-module power links and pack interconnect rated to 1500 V DC, with orange HV-identification jackets, calibrated-torque lug terminations, and hi-pot testing on every assembly. BMS voltage-sense and balance leads are built on the same bill of materials.
Do you build solar / PV string harnesses?
Yes. PV string and combiner wiring with MC4-compatible terminations, UV-stable jackets, and 1500 V DC rating, hi-pot tested for insulation integrity.
Can you make high-current busbar and lug assemblies?
Yes. Laminated and flexible busbar, plus lug and stud interconnect to 250 A, with crimp pull-test and calibrated-torque records for traceability.
Which connector systems do you terminate?
We hold dies and termination specs for Amphenol (including SurLok HV), TE Connectivity, Molex, Phoenix Contact, and JST, plus MC4-compatible PV and lug / busbar terminations. For proprietary parts, send three free samples and we'll cut dies in week one.
How fast will I hear back on an RFQ?
Our engineering team replies to quote requests within one business day, including feasibility, a tooling/NRE estimate where relevant, and a sample lead time. Send a drawing, BOM, or a description of the application to start.
