Inverters

Industrial inverters These are units with a capacity of over 30 kW for commercial installations: photovoltaic farms, production halls, warehouses, cold stores, and farms with high energy consumption. In this category, we have collected inverters Growatt two classes: network MAX 60–125 kW for clean generation and hybrid WIT up to 125 kW for projects combining photovoltaics with industrial energy storage.

TL; DR: On-grid: Growatt MAX 60–125 kW (6–8 trackers MPPT, IP65). Hybrids: WIT-HU 50–100 kW and WIT-XHU 36–125 kW (up to 10 trackers MPPT, IP66), compatible with high-voltage batteries AXE racks and cabinets ACE WIT The 50K-HU is scalable up to 300 kW.

Industrial PV inverter and frequency converter

Two different devices are sometimes called the same thing. This category includes C&I class photovoltaic inverters —they convert direct current from PV modules to alternating current and feed it back to the installation or grid. We do not sell variable frequency drives (VFDs) for controlling pump, fan, or conveyor motors—these are a separate branch of industrial automation and are manufactured by other manufacturers.

If you're looking for a device to regulate engine speed, this isn't the right category. If you're looking for an inverter for a photovoltaic farm, a PV hall, or a project combining photovoltaics with energy storage, you've come to the right place.

What are Industrial Inverters (C&I)

An industrial inverter differs from a home inverter in terms of scale and architecture: higher power per unit, more independent trackers MPPT for extensive PV generators with multiple orientations, and a design designed for parallel operation of multiple units. In commercial installations, string inverters of this class are connected into blocks, which simplifies servicing – a single failure only disables part of the power.

The conditions for connecting installations of this scale are agreed individually with the distribution network operator - verify the formal and technical requirements with your DSO at the design stage.

Who are inverters above 30 kW for?

Photovoltaic farms. Door Line MAX 60–125 kW with 6–8 trackers MPPT is a typical string inverter for farms - from small ground installations to projects combined from multiple units.

Manufacturing companies and logistics. In-hall installations reduce energy costs during plant operating hours. Hybrid WIT allow you to add storage and shift energy consumption to peak pricing hours and maintain power to critical loads.

High-use farms. Cold stores, dryers, livestock – IP65/IP66 housings allow for installation in harsh environmental conditions.

PV installation companies and contractors. We support the selection of units for the project: configuration of inverters, battery storage units, and communication accessories in a single specification, with pallet logistics from our own warehouse.

FAQ - Industrial Inverters

Which inverter for a photovoltaic farm?

For farms without energy storage, the standard series string inverters are MAX 60–125 kW – Higher capacities are achieved by connecting multiple units in parallel. If the project includes energy storage, choose hybrids. WIT: HU versions work with racks AXE HV and wardrobes ACE 209H-2H, a WIT 50K-HU scales up to 300 kW.

100 kW Inverter - on-grid or hybrid?

In the 100 kW class we offer both options: network MAX 100KTL3-X2 LV (8 trackers MPPT) for clean generation and hybrid WIT 100K-HU and WIT 100K-XHU (10 trackers MPPT) for installations with battery storage. The project's business model is decisive: energy sales/self-consumption only, or storage and emergency power supply.

How many trackers MPPT has an industrial inverter Growatt?

Door Line MAX has been since 6 (MAX 60KTL3 LV) up to 8 trackers (MAX 100–125KTL3-X2 LV). Hybrids WIT — from 4 (WIT 36K–50K-XHU) up to 10 trackers (WIT 75K–125K). A large number of independent MPPT allows you to design strings of different orientations and lengths without losing fit.

What energy storage for an industrial inverter WIT?

Series WIT-HU from 50 kW cooperate with high-voltage racks AXE and wardrobes ACE 209H-2H (modules of 16,128 kWh, until 209,6 kWh in the closet). Series WIT-XHU work with rack battery AXE 5.0H-E1. We will select the capacity to suit the facility's consumption profile as part of our design support.
