Solis S6-eh3p(12/15/20)k-h 3 Phase Hybrid Inverter
Three phase
Solis S6-eh3p(12/15/20)k-h 3 Phase Hybrid Inverter handles Three phase of hybrid conversion - PV, battery and grid on one DC bus - which keeps the wiring, the monitoring and the warranty on a solar-plus-storage job under one device.
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
- Backup-capable installations that must ride through utility outages
- 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
Who It Is For
- O&M providers who need spares and firmware support from one source
- PV installers and EPC contractors specifying inverters for grid connection approval
- Distributors carrying inverter lines for commercial rooftop work
- System integrators building solar-plus-storage and microgrid systems
Problems It Solves
- Monitoring that cannot be read by the customer's existing supervisory system
- 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
Technical Features
- Smart cooling with temperature-based derating rather than abrupt shutdown
- 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
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.
| Grid connection | Three phase |
|---|---|
| Brand | Solis |
| Nominal voltage | 600V |
| Communication | CAN/RS485 |
Quality Control
- Packing inspection and photo record before container loading
- 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
Customization Options
- 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
- Extended warranty term
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
Mount out of direct afternoon sun and leave the clearance the manual specifies for airflow
- 2
Commission the monitoring interface at the same visit, not as a follow-up trip
- 3
Record the firmware version so a later fleet update can be planned
- 4
Verify the array string voltage against the MPPT window at the site's record low temperature
- 5
Select the grid code for the destination market before energising
