Three-Phase High-Voltage Hybrid Inverter · BE5-10KW-3PH (HV)
Three-phase high-voltage hybrid inverter with power ratings from 5 to 10 kW and three independent MPPT trackers for maximum flexibility in PV array design. Perfect solution for residential installations, commercial and small-scale industrial projects requiring battery storage and autonomous operation. Certified for grid connection in Spain, Europe and the United Kingdom.
Overview
Bexie Energy’s BE5-10KW-3PH (HV) three-phase hybrid inverter is the high-voltage solution for three-phase solar self-consumption installations that require battery storage and maximum flexibility in the design of the PV array. With power ratings of 5 to 10 kW and three independent MPPT trackers, it optimises output in installations with multiple orientations or partial shading.
Its high-voltage (HV) version is compatible with high-voltage batteries, offering greater efficiency in the charging and discharging cycle and reducing DC wiring losses compared with equivalent low-voltage systems.
Technical specifications of the three-phase HV hybrid inverter

Applications of the three-phase 10 kW hybrid inverter
- Residential solar self-consumption with three-phase installation
- Small businesses and shops with three-phase consumption
- Installations with multiple panel orientations (south, east, west)
- Homes with swimming pool, air conditioning or other high-consumption loads
- Installations requiring backup against grid outages
- Self-consumption projects with HV battery storage
Advantages of the 3 independent MPPT trackers
The three independent MPPT (Maximum Power Point Tracking) trackers allow up to three strings of solar panels with different orientations, tilts or shading conditions to be connected, optimising the output of each group independently.
- Maximum output with panels in different orientations
- Lower impact of partial shading on total output
- Greater flexibility in PV array design
- Ideal for roofs with multiple pitches or surfaces
- Phased expansion of the installation
High voltage (HV) vs low voltage (LV) — which to choose?
- High-voltage batteries offer greater efficiency in the charging and discharging cycle
- Lower DC wiring losses by operating at a higher voltage
- Greater storage capacity in less physical space
- Ideal for higher-power installations (5-10 kW)
- The LV version is more suitable for lower-power installations (3.6-6 kW)
Operating modes
- Grid mode (on-grid): optimises solar self-consumption and manages HV battery charging
- Island mode (off-grid): fully autonomous operation with no grid connection
- Backup mode: automatic switchover during grid outages
- Scheduled mode: charging during off-peak hours to optimise energy costs

Frequently asked questions about three-phase hybrid inverters
Do I need a three-phase installation to use this inverter?
Yes, the BE5-10KW-3PH is a three-phase inverter and requires a three-phase electrical installation. If you only have single-phase, we recommend our BE3.6-6KW-1PH (LV) single-phase hybrid inverter.
What’s the difference between HV and LV in hybrid inverters?
HV (high voltage) works with batteries operating at a higher voltage, which improves system efficiency and reduces wiring losses. LV (low voltage) is more cost-effective and suitable for lower-power installations. For 5-10 kW three-phase installations, the HV version is the most recommended.
What are the 3 MPPT trackers for?
Each MPPT tracker manages an independent group of solar panels. Having 3 allows panels facing south, east and west to be connected separately, or to separate groups with different shading, maximising the total output of the installation.
Is it certified for installation in the UK and EU?
Yes, it holds the main European certifications (IEC 62109, IEC 50549, VDE 4105) and meets the requirements of UK G98/G100 grid connection regulations for self-consumption installations with batteries.
Can it operate without a battery in self-consumption-only mode?
Yes, the inverter can operate in grid-only mode with no battery connected, managing solar self-consumption and exporting any surplus to the grid. The battery can be added later when the system needs to be expanded.
