NEOVOLT T5 Three-Phase Hybrid Inverter for Solar PV Integration
The BW-INV-TPH5K combines photovoltaic conversion, battery charging, grid interaction and backup output within a three-phase hybrid inverter platform.
Its three independent MPPT trackers provide flexibility when designing solar arrays across different roof orientations. Installers can configure separate PV strings within the permitted voltage and current limits rather than forcing all modules into one operating arrangement.
The inverter supports up to 10kW maximum PV input power, enabling DC-oversized array designs where the site conditions and generation profile justify them. Actual AC output remains subject to the inverter’s rated power and applicable grid settings.
Energy Management and Monitoring
The inverter’s internal energy management system coordinates supported PV generation, battery charging and discharging, grid interaction and connected loads.
The included meter provides the electrical measurements required for the configured operating strategy.
Remote monitoring, diagnostics and communication functions depend on the installed connectivity equipment and applicable software configuration.
For professional installers, these functions are particularly useful when commissioning systems for solar self-consumption, monitoring battery performance and providing ongoing customer support.
Three-Phase Backup Power and System Scalability
The NEOVOLT T5 hybrid inverter includes a dedicated backup output for appropriately designed electrical circuits.
It can support selected loads during a grid interruption when the battery has sufficient available energy and the system is installed with the required electrical protection, isolation and switching arrangements.
A 20kWh battery does not automatically make this a whole-house backup system. The installer must assess phase distribution, connected loads, motor starting currents and the inverter’s backup power limits before specifying which circuits will remain supplied.
For projects requiring increased inverter output, the NEOVOLT three-phase platform also supports manufacturer-approved parallel inverter operation. NEOVOLT’s system documentation describes configurations with up to six compatible inverters operating in parallel.
The final design must account for the applicable inverter models, parallel connection equipment, firmware compatibility and approved battery architecture.
Installation Planning for Professional Solar Installers
The NEOVOLT T5 system is intended for installation and commissioning by qualified electrical and solar PV professionals.
Its modular construction allows the inverter and battery system to be installed as a coordinated arrangement, subject to the manufacturer’s mounting, spacing and connection requirements.
Before specifying this configuration, the installer should assess the property’s three-phase electrical supply, expected PV generation, daily energy consumption, backup requirements and available installation space.
Particular attention should be given to:
- Battery connection and BMS communication: Use the manufacturer-approved wiring arrangement and compatible firmware.
- Grid compliance: Verify the applicable country-specific grid-code settings and certification requirements.
- Backup circuit design: Confirm protected loads, switching requirements and electrical isolation.
- Battery placement: Allow for equipment weight, ventilation, service access and environmental conditions.
- Future expansion: Plan battery connections and additional equipment around the intended system capacity.
The system’s IP65 protection supports installation flexibility, but the final location must comply with NEOVOLT’s installation instructions and local electrical regulations.
For retrofit installations, compatibility with the existing PV inverter, metering configuration and electrical distribution system must be assessed before ordering.
NEOVOLT Energy Storage Kits for European Solar Installers and EPC Contractors
This 20kWh-class three-phase package is designed for professional buyers who need a defined inverter and battery configuration rather than sourcing individual system components from different manufacturers.
It is particularly relevant for residential solar PV installations with three-phase grid connections, new-build photovoltaic projects and selected light commercial applications where battery autonomy is more important than high instantaneous discharge power.
For repeat installations, a consistent NEOVOLT system configuration can simplify procurement, technical documentation and commissioning procedures.
