Description
xVoltacon 15kW 3 Phase Hybrid Solar Inverter 48V MPPT IP65 G99
The Voltacon InfiniSolar 15kW is a three phase hybrid solar inverter designed for commercial buildings, farms, and large residential properties requiring 400V three phase output with integrated 48V battery storage. G99 approved and IP65 rated, it supports grid-tie, off-grid, and hybrid operation in a single unit, with a large touchscreen HMI for straightforward commissioning and control.
Key Features
- 15kW three phase output, 400V (P-P)
- G99 approved and ENA registered for UK grid connection
- IP65 weatherproof enclosure for indoor plant rooms or outdoor installation
- Dual MPPT, up to 26A per tracker, 22.5kW max PV input
- Maximum PV input voltage: 1000VDC
- Adjustable battery charging current up to 300A
- 150% unbalanced load support across three phases
- Dual AC outputs for smart load management
- Parallel operation for up to 6 units
- Built-in Wi-Fi monitoring
- Large touchscreen HMI display
- RS485 BMS and CAN interface for lithium battery communication
Product Overview
In grid-tie mode, the inverter delivers up to 15kW at 230VAC per phase, with a power factor exceeding 0.99 and maximum DC-to-AC conversion efficiency above 96%. The dual MPPT design supports up to two string inputs per tracker, accommodating a wide range of PV array configurations.
In off-grid and hybrid modes, the unit operates from a 48VDC battery bank (40 to 62VDC), delivering pure sine wave output at 230VAC per phase. The 300A adjustable charging current allows rapid battery charging from either PV or grid, making it well suited to systems with large battery banks.
The dual AC output allows one output to supply priority loads while the second output manages non-critical loads, improving overall energy management and reducing unnecessary battery draw.
Applications
- Commercial buildings and industrial units requiring three phase power
- Farms and rural properties with three phase supply
- Large residential properties needing full-house backup
- Self-consumption systems with export management via energy meter
- Multi-unit parallel installations for higher capacity systems
Installation and Safety Notes
This inverter must be installed by a qualified electrical engineer or MCS-accredited solar installer. G99 applications require DNO notification and approval prior to connection. Three phase wiring, battery connections, DC isolation, and earthing must comply with IET Wiring Regulations and BS 7671. Do not attempt installation without the appropriate qualifications and grid approval in place.
