Growatt MAC 15/20/25/30/36KTL3-XL 3 Phase 220V On Grid Inverter
Three phase
Growatt MAC 15/20/25/30/36KTL3-XL 3 Phase 220V On Grid Inverter converts Three phase of PV output for direct grid export. Multiple MPP trackers let one unit serve roof sections at different orientations without splitting the array across more inverters.
What This Product Changes On Your Project
- Grid protection built in - anti-islanding, insulation monitoring, residual-current monitoring and surge protection
- Outdoor-rated enclosure that can be wall-mounted next to the array instead of inside a plant room
- Standard monitoring interfaces so the plant reports into existing supervisory software
- Firmware grid codes for export limitation and reactive power control, which is what most utility connection approvals ask for
- Multiple MPP trackers, so roof sections at different pitches and orientations do not have to share one string
Application Scenarios
- Off-grid and weak-grid sites running PV, battery and generator together
- Industrial microgrids switching between grid-tied and island operation
- Commercial rooftop PV exporting to the utility under a net-metering or feed-in scheme
- Ground-mount arrays where several sub-arrays share one inverter station
- Solar-plus-storage retrofits on sites that already have PV
Who It Is For
- System integrators building solar-plus-storage and microgrid systems
- Asset owners standardising on one inverter platform across a portfolio
- O&M providers who need spares and firmware support from one source
- PV installers and EPC contractors specifying inverters for grid connection approval
Problems It Solves
- Grid codes that reject an installation without export limitation and reactive power control
- Conversion loss and heat derating that quietly erode plant yield in summer
- Separate PV and storage conversion stages that double the failure points and the commissioning time
- Monitoring that cannot be read by the customer's existing supervisory system
Technical Features
- RS485 and wireless monitoring interfaces
- Independent MPP trackers, each tracking its own string set
- Transformerless conversion topology
- DC switch, DC reverse-polarity protection and surge protection on both DC and AC sides
- Anti-islanding, grid monitoring and residual-current monitoring for utility approval
Published Specification Data
These figures come from the manufacturer datasheet for this model. Where a value you need is not listed, ask for the full datasheet rather than assuming a typical figure.

Quality Control
- Incoming inspection of cells, power electronics and structural parts before assembly
- Capacity and internal-resistance grading so cells within a pack are matched
- Full-function test on every finished unit, not a sample from the batch
- Insulation and dielectric withstand testing on completed assemblies
- Aged and burn-in run before packing, so early-life failures happen in the factory
Customization Options
- Customer branding on packaging and documentation
- Grid code and AC voltage configuration for the destination market
- Monitoring accessory selection - Wi-Fi, GPRS or RS485 to an existing logger
- DC connector type to match the array already specified
How It Compares With The Alternatives
| Separate PV inverter plus battery inverter | One conversion stage means one set of wiring, one monitoring platform and one warranty, at the cost of less freedom to mix brands later. |
|---|---|
| A microinverter array | String conversion costs less per kW at commercial scale; microinverters win on complex shading and per-module monitoring. |
| An oversized single inverter | Several MPP trackers serve differently oriented roof sections without splitting the array, so one unit covers what would otherwise need two. |
Getting This Product Right On Site
- 1
Commission the monitoring interface at the same visit, not as a follow-up trip
- 2
Record the firmware version so a later fleet update can be planned
- 3
Verify the array string voltage against the MPPT window at the site's record low temperature
- 4
Select the grid code for the destination market before energising
- 5
Mount out of direct afternoon sun and leave the clearance the manual specifies for airflow
