Lovsun US Version 3 Phase Hybrid Solar Inverter 14-18KW
14-18 kW / Three phase
Lovsun US Version 3 Phase Hybrid Solar Inverter 14-18KW is a hybrid solar inverter rated at 14-18 kW / Three phase. It manages PV input, battery charge and discharge, grid import and export and backup switchover from a single unit, so a solar-plus-storage system needs one power conversion stage instead of two.
What This Product Changes On Your Project
- 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
- Transformerless topology keeps conversion loss and unit weight down at this power class
- Grid protection built in - anti-islanding, insulation monitoring, residual-current monitoring and surge protection
Application Scenarios
- 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
- Backup-capable installations that must ride through utility outages
- Off-grid and weak-grid sites running PV, battery and generator together
Who It Is For
- Distributors carrying inverter lines for commercial rooftop work
- 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
Problems It Solves
- Long lead times on replacement units when a plant is down
- Roof geometry that forces strings of different lengths and orientations onto one inverter
- 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
Technical Features
- 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
- Smart cooling with temperature-based derating rather than abrupt shutdown
- RS485 and wireless monitoring interfaces
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
- 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
- Serialised traceability from cell batch to finished unit
Customization Options
- Monitoring accessory selection - Wi-Fi, GPRS or RS485 to an existing logger
- DC connector type to match the array already specified
- Extended warranty term
- Customer branding on packaging and documentation
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
Record the firmware version so a later fleet update can be planned
- 2
Verify the array string voltage against the MPPT window at the site's record low temperature
- 3
Select the grid code for the destination market before energising
- 4
Mount out of direct afternoon sun and leave the clearance the manual specifies for airflow
- 5
Commission the monitoring interface at the same visit, not as a follow-up trip
