Inverters

A photovoltaic inverter is a key component of any PV installation, responsible for converting direct current (DC) generated by photovoltaic modules into alternating current (AC) that matches grid parameters. A modern inverter ensures high conversion efficiency, optimises system performance, and offers monitoring and safety functions. At G-VOLT Wholesale, we offer devices from GoodWe, SolarEdge, Huawei, Deye – from compact single-phase models to hybrid solutions for commercial and industrial installations.

How does a photovoltaic inverter work?

The inverter receives energy from PV panels and adjusts the operating point via the MPPT (Maximum Power Point Tracking) system, maximising energy yield. It monitors grid parameters, synchronises frequency and voltage, and in hybrid installations works with energy storage systems to enable backup power mode.

Types of inverters in our offer

• On-grid inverters – working with the power grid, with multiple MPPT trackers, monitoring systems, and AC/DC protections.
• Hybrid inverters – combining on-grid functions with the ability to store energy in LV or HV battery systems.
• Off-grid inverters – for stand-alone systems ensuring energy independence.
• Single-phase and three-phase models – from small installations to large-scale industrial projects and PV farms.

Technologies and features

• European efficiency up to 98%, wide MPPT voltage ranges.
• Wi-Fi, LAN, RS485 communication, integration with meters and EMS systems.
• Support for power optimisers – including SolarEdge and Huawei.
• Protections: short-circuit, surge protection, Rapid Shutdown.
• System monitoring via manufacturer apps and portals.

B2B applications

G-VOLT inverters are used in commercial, industrial, and agricultural installations – from factory rooftops to ground-mounted large PV farms. Hybrid inverters increase self-consumption and provide backup power, which is especially important for facilities requiring uninterrupted operation.
