Product Lines
Every line is built in our own factory — from compact 1kVA rack units to 600kVA industrial systems.
UPS Power Supply
Online, offline, lithium, three-phase high-frequency and transformer-isolated industrial UPS from 500VA to 600kVA — tower and rack, plus 100/110/120V low-voltage models for global markets.
13 series →Power & Telecom Inverters
Rack-mount DC-AC inverters that turn station and telecom DC buses from 12 to 300VDC into fully isolated 220Vac power for substations, base stations, HVDC rooms and industrial control.
7 series →Switching Power Supplies & Rectifiers
19-inch AC-DC rectifiers, embedded telecom power systems and DC-DC converters that deliver stable 24 / 48 / 110 / 220VDC to base stations, DC panels, substations and industrial control cabinets.
5 series →Solar Inverters
Single-phase and three-phase hybrid inverters from 1.2 kW to 15 kW — off-grid, grid-interactive, split-phase 120/240 V and 380 V three-phase, on 12 V to 48 V batteries.
6 series →Storage Batteries
LiFePO4 battery modules from 1.28 kWh to 32.2 kWh in seven form factors — wall-mounted, stacked, 19-inch rack, lead-acid replacement, tower, vertical and IP65 floor-standing.
7 series →All-in-One ESS
Inverter, BMS and LiFePO4 battery in one cabinet — 300 W portable packs through 15 kW three-phase systems, 896 Wh to 32 kWh, for the EU, US and export markets.
4 series →Accessories & BMS
SNMP cloud monitoring cards, smart BMS boards and matched LiFePO4 chargers — the parts that decide whether a system reports honestly and reaches its rated cycle life.
3 series →Portable Power Stations
Sealed and rugged portable power stations, 1.0 kWh to 16.08 kWh and 1.2 kW to 5 kW, with LiFePO4 cells, pure sine inverters, MPPT solar input and 10 ms UPS transfer for field, commercial backup and off-grid use.
7 series →Hot Products
The series our global buyers order most — lithium UPS with built-in LiFePO4, rack inverters, long-runtime systems and the LiFePO4 pack behind them.
ET1-3K Series
Online double-conversion tower UPS with a Class A LiFePO4 battery inside — 30 minutes of full-load backup (23 minutes on ET3K) in one cabinet, maintenance-free.
View detailsET6/10KRS PRO Series
6–10kVA online rack UPS purpose-engineered for long-duration lithium backup — single-phase or three-phase input, single-phase output.
View detailsUS-S / US-R Series
Built for the North American panel: 120/240 V split-phase output, anti-reflux CT in the box, and a 10 ms transfer that keeps a well pump and a furnace controller alive.
View detailsHC Series
The same 51.2 V platform in a 19-inch chassis — 440 mm wide, 2U to 5U depending on capacity, for cabinets, telecom racks and containerised systems.
View detailsBuilt in our own factory, shipped worldwide
HighIdea Power Supply System is the manufacturing brand of Shenzhen Youwei Energy Technology Co., Ltd. — a factory-direct maker of uninterruptible power supplies, industrial UPS systems, DC-AC rack inverters and LiFePO4 battery packs.
Unlike trading companies, every product line on this website is produced on our own Shenzhen production lines. That means direct engineering support for your specification, factory-direct pricing, and full OEM/ODM control over capacity, runtime, voltage, communication protocols and branding.
Why buyers choose lithium
- 5x backup time in the same space — LiFePO4 packs occupy about one-third the volume of lead-acid and deliver 1,200+ cycles versus 200–400.
- Zero maintenance — sealed, integrated battery management; no watering, no gassing, no scheduled replacement rounds.
- Built for harsh grids — wide input range (110–300VAC), lightning protection and generator compatibility as standard.
- Global voltage coverage — 100V, 110V, 120V, 127V, 220V, 230V and 240V output versions for Japan, the Americas, Europe, the Middle East, Southeast Asia and Africa.
- Documentation that clears customs — UN38.3 test reports and MSDS travel with the quotation, not after a round of chasing.
Battery packs and energy storage
Beyond the UPS line, the same plant builds the battery that goes into it — and the systems built around it:
- LiFePO4 battery packs, 12 V to 800 V — drop-in 12 V and 24 V replacements, 48 V rack and LP48 platforms for UPS and hybrid solar, and high-voltage series stacks with master-slave BMS for commercial inverters.
- Residential energy storage — 5 kWh wall-mount through 30 kWh stackable home batteries, with the inverter protocol loaded at the factory.
- Commercial and industrial storage — 100 kWh air-cooled cabinets, 215 kWh liquid-cooled cabinets and 20 ft containerised BESS.
- Rack and cabinet systems — 19-inch modules and pre-wired cabinets for integrators who bring their own enclosure and EMS.
- Portable power stations — 2–20 kWh wheeled and case-mounted systems for site power and events.
Most of this leaves the factory under someone else's brand. Enclosure tooling, BMS firmware, inverter protocol matching and the certification documentation for the target market are all part of an OEM/ODM platform — see OEM / ODM or start from the energy storage overview.
