Description
xVoltacon InfiniSolar 15kW 3 Phase Hybrid Inverter 48V IP65 G99 | Ex Demonstration Unit
This 15kW three phase hybrid solar inverter is an ex demonstration unit from the Voltacon technical lab in Coventry. Our engineers installed it, ran it and looked after it under controlled conditions. It was taken out of service when the lab system was expanded to 50kW and needed a larger inverter. It was not removed because of a fault. The latest firmware is already installed, and it is the same InfiniSolar model we currently supply new.
If you need a G99 approved, IP65 rated three phase hybrid inverter that works with a 48V lithium battery bank, this unit gives you the same hardware and capability as a new one at a much lower price.
Key Features
- 15kW rated three phase output, 400VAC phase to phase (230VAC per phase)
- Grid tie, off grid and hybrid operation in a single unit
- G99 approved and ENA registered for UK grid connection
- Dual MPPT trackers, 26A per tracker, up to 22.5kW of PV input
- Maximum PV input voltage of 1000VDC
- 48V battery input with adjustable charging current up to 300A
- RS485 BMS and CAN communication for compatible lithium batteries
- IP65 weatherproof enclosure for indoor or outdoor mounting
- Dual AC outputs for separating priority and non critical loads
- Parallel operation with up to 6 units
- Large touchscreen HMI and built in WiFi monitoring
- Latest firmware installed and tested before dispatch
Product Overview
Used inverters from the open market often come with an unknown history: years on a hot wall, poor installation, or a fault the previous owner never mentioned. This unit is different. It has only ever run in our own lab, and we know exactly how it was installed, configured and maintained.
In grid tie mode the inverter supplies up to 15kW at 230VAC per phase, with a power factor above 0.99 and peak DC to AC efficiency above 96%. The two MPPT trackers each take two strings, so you can split an array across different roof orientations.
In hybrid and off grid modes it runs from a 48VDC battery bank (40 to 62VDC) and delivers pure sine wave output on all three phases. Adjustable charging up to 300A lets you recharge a large battery bank quickly from solar or the grid. With the dual AC outputs, essential circuits stay on one output while non critical loads go on the second, which reduces unnecessary battery discharge.
Because it runs on 48V low voltage storage, you can build the system around widely available 48V lithium batteries instead of a high voltage battery stack. That makes it a practical choice for farms, workshops, small commercial units and large homes with a three phase supply.
Condition
Used, fully working ex demonstration unit. The inverter operates normally and has had the latest firmware installed. There are some cosmetic scratches on the casing. The touchscreen display works like new. The photos show the actual unit for sale.

Installation and Safety Notes
This inverter must be installed by a qualified electrician or MCS accredited solar installer. Grid connected systems need a G99 application and DNO approval before connection. Correct cable sizing, DC and AC isolation, fusing, surge protection and earthing are essential, and all work must comply with BS 7671 and local regulations. Plan the wall mounting to take the 75 kg weight.
The equipment operates at hazardous DC and AC voltages and connects to high current battery systems. Do not attempt DIY installation. Incorrect installation can cause fire, electric shock or equipment damage.
Delivery and Support
Due to its size and weight, this inverter is dispatched by pallet courier from our Coventry warehouse. Our UK technical team is available to help with system design and commissioning questions before and after purchase. Only one unit is available.
