Power & Telecom Inverters
DC bus in, clean isolated AC out — inverter systems for sites where the primary source is a station battery or telecom DC panel, not the utility grid.
HighIdea Power & Telecom Inverters convert a DC bus into clean, galvanically isolated AC. They are built for sites where the primary source is a battery bank or a station DC panel rather than the utility grid: substations and power plants, telecom base stations, railway signalling, HVDC data rooms, RTU/SCADA cabinets and industrial control panels.
These are not solar inverters. Solar (PV) inverters in the Solar Inverters range are designed around an MPPT charger and a PV array; power and telecom inverters are designed around a DC bus, strict AC/DC isolation, no back-feed noise into the DC system and zero or near-zero transfer time. Where the site needs an AC-input UPS with its own battery instead, see UPS Power Supply.
The range is split by operating principle:
- Online DC-AC Inverters — full double conversion, 0 ms transfer and continuous inverter-fed output. H 1-3kVA, H 6-20k, HM 3-15kVA, HP 6k and HT 1-20k.
- Standby & Offline Inverters — AC-priority or DC-priority operation with a fast transfer, higher efficiency and a lower cost where a brief switch is acceptable. HB 5/10k and HTB 1-12kVA.
Specifying a unit. Confirm the DC bus voltage first (12 / 24 / 36 / 48 / 60 / 72 / 110 / 220 / 240VDC or a wide 160-300VDC window), then the required kVA and kW, the output voltage and frequency (220 / 230 / 240Vac, 50 or 60Hz), the acceptable transfer time, and whether galvanic isolation or an external isolation transformer is mandated. Also state the battery chemistry, the required autonomy and the communication protocol (RS485 / SNMP / Modbus) for the site monitoring system.
All models are built in our own factory and support OEM/ODM customization of capacity, DC input voltage, output voltage, enclosure format, communication protocol and branding. Pair them with LiFePO4 battery packs or a conventional VRLA string sized to the site's autonomy requirement.
