Tīkla virknes invertors SolaX X3-MEGA G2, 40 kW, trīsfāžu

The 3-phase X3-MEGA G2 string inverter from SolaX is a state-of-the-art, safety-oriented component for your solar project.

• Reactive power compensation at night
• Heat dissipation reduces system weight and size by more than 10%
• I-U curve diagnosis

The 3-phase, 40 kW X3-MEGA G2 string inverter from SolaX (MPN: 1030120206) offers efficient use of your solar system. It is equipped with 4 MPPTs with 2 strings per tracker, so it always extracts the maximum power from your PV system, even with different irradiation conditions or module orientations.

Functions such as reactive power compensation at night, integrated export power control and precise I-U curve diagnosis give you maximum control and high yields. Operation can be monitored around the clock via the app, and arc fault detection (AFCI) is available as an option. With its variability, performance and reliability, this grid-connected string inverter is a solution for a future-proof and efficient energy supply.

The inverter in a grid-connected system

The inverter converts the direct current generated by the solar modules efficiently into usable alternating current, as needed in households and businesses. With its three-phase, transformerless design, it ensures stable and powerful energy conversion. The generated direct current (DC) is converted into grid-compliant alternating current (AC) and fed directly into the public power grid. Integrated surge protection on the AC and DC side protects your system against damage from lightning strikes or voltage spikes.

PV oversizing and output overload

With oversizing, you can connect solar modules with up to 1.5 times the rated power of the inverter, which gives a higher electricity yield even in low sunlight. Thanks to output overload, the inverter can temporarily deliver more power than its rated power, so power peaks are used optimally.

Parallel connection

With the SolaX Datahub (not included), several inverters of the series can be combined in one system to expand the power of your photovoltaic system flexibly; the Datahub supports up to 60 inverters in parallel operation. With an electricity meter in the main circuit, zero export is also possible, so that no surplus electricity is fed into the public grid.

Possible application areas

• Commercial photovoltaic systems
• Charging station infrastructure
• Industrial companies
• Grid-parallel operation and self-consumption optimisation

Reactive power compensation

Reactive power compensation at night means that your inverter contributes to the stability of the power grid even at night, when no solar power is generated: it can feed reactive power into the grid or absorb it. This function helps the power grid to work reliably and to meet the requirements of the grid operator, so your system is equipped for current and future grid requirements.

I-U curve diagnosis

The inverter regularly checks how much current your solar modules generate at different voltages. In this way the system detects early when individual modules deliver less power – for example due to soiling, ageing or technical problems – and you receive timely notifications so you can react quickly.

Integrated export power control

You can specify exactly how much electricity from your system is fed into the public grid: feed-in can be prevented completely (zero export) or limited to a specific value. The inverter controls this automatically and continuously adjusts the feed-in to your settings, so you meet the requirements of your grid operator and can optimise self-consumption without additional accessories.

Safety and protection

• AC overcurrent and short-circuit protection
• DC switch, reverse polarity protection, insulation protection, feed-in monitoring
• Reverse current monitoring
• Grid monitoring
• Insulation monitoring
• Protection against leakage currents
• Residual current and string fault detection
• Over/undervoltage protection
• Anti-islanding protection
• Surge protection (DC/AC): Type II/Type II
• AFCI: optional

Arc fault detection (AFCI) – optional

If PV modules, plugs or cables are installed incorrectly or damaged, electric arcs can occur and cause fires. To prevent such fires quickly, SolaX has developed an optional arc fault detection that can be installed for a higher level of safety for you and your PV system.

SolaXCloud

SolaXCloud is a platform for managing your energy. It offers clear monitoring of energy consumption and electricity generation as well as simple control of connected devices, and your data is transmitted securely. With the monitoring app you can supervise your photovoltaic system via Wi-Fi, LAN or 4G, view alarms, adjust settings and plan maintenance. To do this, plug the dongle into the USB port of the inverter; after switching on, the connection to the app is possible immediately. The QR code for downloading the app is in the user manual.
