Hybrid inverters
HBD three-phase hybrid inverter
Bi-directional 3-phase hybrid MPPT inverters, 5–250 kVA, for C&I sites, microgrids and cold storage.
Overview
What it does
The HBD and ECO-HBD series are three-phase bi-directional hybrid MPPT inverters from 5 to 250 kVA.
A bi-directional active front end charges the batteries from solar or grid, exports surplus PV to the grid through net metering and supports BESS functions such as peak shaving and time-of-day shifting.
The ECO-HBD cold inverter variant adds VFD coupling for cold storage sites.
Applications
- Process industries and mills
- Telecom BTS sites
- Cold storage
- Microgrids
- Hospitals, schools, offices, malls and commercial buildings
- Banks/ATMs, petrol pumps, gyms, poultry farms and bungalows
- Industrial peak shaving and avoiding sanctioned-load penalties
Certifications and standards
- Grid export with anti-islanding protection
Features
Why engineers choose it
- Active front end: low-distortion input current at unity power factor and grid export of surplus PV
- BESS functions: peak load shaving, load levelling, voltage/frequency regulation and time-shifting
- Scheduling by keypad or PLC, time-of-day tariff charging and programmable night-saving mode
- Three priority modes: hybrid with export, hybrid without export, and off-grid
- AC coupling with string inverters; works with wind, hydro and DG sets
- Cold storage variant (ECO-HBD): VFD coupling at the DC end, controlled through a PLC
- Up to 100% load imbalance on 3-phase models
- Pure sine wave output with protection against grid fluctuation, overload, short circuit, reverse polarity and surge
