## Solar generation for rooftops and businesses

Huawei SUN2000-40KTL-M3 is a 40 kW three-phase grid-connected PV inverter for commercial rooftops, business premises and appropriately designed ground-mounted plants. Four independent MPPTs and eight string inputs divide the array according to its electrical and physical layout. IP66 protection suits a fixed outdoor installation.

## AC power and energy generation

Rated AC output is 40 kW and maximum apparent power is 44000 VA according to the model specification and selected grid profile. Generation in kWh depends on site, modules, orientation, shading and operating conditions. For a 400 V grid, the current manual lists 98.65% maximum and 98.4% European efficiency.

## Four MPPTs and eight strings

Recommended maximum array power is 60000 Wp. Each of four MPPTs serves two strings; this model has a maximum MPPT current of 27 A and 40 A short-circuit current. Startup is at 200 V, the operating range is 200–1000 V and the full-load MPPT range for a 400 V grid is 540–800 V. Strings sharing one MPPT are designed with matching modules and module counts.

## Operating environment

The manufacturer specifies −25 to +60°C operation, IP66 protection and operating altitude up to 4000 m. Design considers temperature-dependent output, ventilation and installation clearances. Storage temperature is −40 to +70°C.

## Dimensions and cooling

Dimensions are 640 ×530 ×270 mm and this model weighs 43 kg. The 30–40 kW versions use natural convection. The inverter is secured in a fixed installation with access to service and electrical connection points as specified in the manual.

## System configuration

The installation combines correctly sized PV strings, the grid inverter, AC protection, distribution equipment and the utility connection. Metering and control are selected for the project and grid requirements. Where the building also uses storage, its own power and control branch is assessed as a separate part of the energy-system design.

## Monitoring and communication

LED indicators and local WLAN with the app support device setup and inspection. RS485 provides communication with the selected logger and metering. The current manual lists SmartLogger3000, SmartLogger5000B or SmartMGC5000B; a suitable Smart Dongle may be selected for the project. Meter model and firmware are matched together.

## Protection and optimization

The series supports AFCI, PV-string monitoring, insulation and residual-current monitoring, DC protection and integrated PID recovery. DC and AC surge protection follows Type II specifications. Optional optimization is designed for the supported MERC or SUN2000-1600W-PB1 family, firmware and string rules.

## Protection and cable design

The manual gives a reference three-phase 100 A breaker rated at least 500 V AC for this model. Reference copper AC conductors are 16–50 mm²; a suitably designed aluminum option is 35–50 mm². Copper PE is at least 16 mm² and DC input conductors are 4–6 mm². Core count, cable diameter and terminals are checked against the gland and 3L+(N)+PE layout.

## Model selection and building demand

The 40 kW version is selected for the array design, grid connection, load profile and generation-control requirements. Four MPPTs help divide electrically distinct array sections. Sizing separately considers power in kW, energy in kWh, string currents and connection capacity.

## Offer scope and documentation

The offer covers the exact individual inverter model shown. Modules, metering, logger, protection and other project components are selected for the installation. The public Markdown profile contains model-specific specifications and the appropriate system role. Estimated delivery of 2–3 days is the seller’s estimate.
