Hybrid solar inverters 3-P (HBD and Boxer HF Pro)

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.

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
• Boxer HF Pro: high frequency and transformerless, 200% PV oversizing, 24 A per string
• Boxer HF Pro: on-grid and off-grid operation with diesel generator support, under 20 ms transfer
• Boxer HF Pro: AI energy management with PV forecasting and time-of-use pricing
