Description
xVoltacon BYM1000 1000W Solar Microinverter – Dual MPPT WiFi 230V IP67
The Voltacon BYM1000 is a 1000W micro inverter with two independent MPPT trackers for grid-connected solar installations. Each of the two panels it handles gets its own dedicated MPPT channel. Output is 230V AC at up to 96.5% peak efficiency. The IP67 enclosure is rated for outdoor installation directly behind or near the panels.
Ideal for home installations, on balconies, patios and gardens. From August 26th 2026, households are free to use plug-in balcony solar panels with micro inverters.

Product Overview
The BYM1000 is the two-panel version of the Voltacon micro inverter range. Each panel connects to its own MPPT input, so shading or performance variation on one panel does not affect the other. This is a practical advantage on roofs where both panels cannot always be placed in identical conditions.
The high-frequency transformer design provides galvanic isolation between the DC input and the AC output, which improves safety and reduces conducted interference on the AC side. A power factor above 0.99 and THD below 4% meet the grid quality requirements for G98 compliance in the UK.
At 2.39kg and 272.9 x 260.9 x 34.5mm, the unit is light enough to mount directly to a panel frame or rafter bracket without additional structural support.
Applications
- Residential rooftop solar with 2-panel arrays or partial shading
- Balcony solar systems and small garden installations
- Garden rooms, garages and outbuildings
- Installations where minimal DC cabling is required
- Systems requiring module-level monitoring
What Is Included
- 1 x Voltacon BYM1000 micro inverter unit
Installation Notes
Must be installed by a qualified MCS-accredited installer. Grid connection requires G98 compliance (UK). Install in accordance with the BYM1000 installation manual. Ensure adequate airflow around the enclosure. Confirm MPPT voltage range compatibility with the panels being used before installation.
