Solis S6 16kW + Renon Xcellent Plus Installation Guide
⚠️ Important:
This article is a condensed installer reference. Always follow the latest Solis and Renon manuals, project plan set, NEC requirements, AHJ guidance, and the current approved battery compatibility documents before energizing the system.

A typical Solis / Renon storage system includes two primary components.
16 kW split-phase hybrid inverter
3 MPPT inputs
48 V battery platform
Integrated 200 A pass-through / bypass
Smart port for generator, AC coupling, or controllable loads
Up to 290 A max battery-side charge / discharge capability
Solis’s current US product page for the S6-EH2P(9.6–16)K03-SV-YD-L-US family lists 3 MPPTs, 48 V battery architecture, smart port support, integrated 200 A pass-through / bypass, and up to 290 A battery-side current.
Low-voltage LiFePO4 battery system
16 kWh nominal energy
51.2 V nominal voltage
190 A max charge / discharge current
CAN / RS485 communication
Floor or wall mounting depending model / hardware configuration
Renon’s current product page and April 2025 user manual list 16 kWh nominal energy, 51.2 V nominal voltage, LiFePO4 chemistry, 190 A max charging/discharging current, and CAN / RS485 communication.
A typical Solis / Renon system uses the inverter’s integrated backup architecture rather than a separate external backup box. The utility feeds the service equipment, the inverter connects to grid / backed-up loads / PV / battery, and the smart port can be configured for generator or controllable-load use as required by the design. Solis describes this inverter family as supporting whole-home backup, smart-port integration, and integrated 200 A pass-through / bypass.
Install equipment in a dry, ventilated location away from direct heat, corrosives, and flammable materials. Maintain the manufacturer-required clearances and use only code-compliant mounting surfaces and conductor / OCP sizing from the approved plan set. The GoodWe reference guide you shared uses a condensed “installation requirements” section with inverter siting, battery siting, and startup checks, and this shortened Solis / Renon version follows that same pattern.
Mount on a structural, fire-resistant surface.
Keep the unit vertical and maintain the Solis clearance diagram requirements.
Use only approved conduit entries and wiring paths for PV, battery, grid, backup, smart port, and communications.
Install on a suitable wall or floor-mount arrangement per Renon instructions.
Maintain service and ventilation space around the unit.
Follow the Renon mounting, grounding, and communications instructions exactly.
Install the factory mounting bracket on a structural wall.
Set the inverter plumb and secure it per the installation manual.
Verify working clearances before pulling conductors.
Mount the battery in the approved location and orientation.
Complete mechanical anchoring before landing conductors.
Connect PE / grounding, battery DC conductors, and communication cable per Renon’s wiring instructions.
Renon’s current user manual identifies the Xcellent Plus-US as an IP65 16 kWh, 51.2 V system with CAN / RS485 communications and gives the model specs used here.
Land PV strings on the inverter PV inputs.
Observe Solis polarity, string sizing, voltage, and current limits.
Use code-compliant disconnecting means and labeling.
Land the battery DC conductors on the inverter battery terminals.
Connect the Renon communication cable to the inverter battery communications port.
Confirm the battery model / protocol is supported by the current compatibility documentation before commissioning. Solis’s current US product materials also point installers to the battery matching / compatibility documentation for supported battery brands and models.
Land utility conductors at the grid port.
Land backed-up loads at the backup port.
Use the smart port for generator or controlled-load functions only when required by the project design.
Solis’s current local-settings and SolisCloud guidance explicitly includes storage mode settings, battery settings, smart port settings, and meter / CT settings as part of commissioning for this inverter family.
Confirm battery communications are healthy.
Confirm any required external meter / CT configuration is wired correctly and matches the commissioning settings.
Confirm no communication alarms are active before final startup.
Solis’s current Bluetooth / local-settings guides show battery selection, meter / CT configuration, grid code selection, storage mode settings, and battery settings as part of the required quick-setup flow.
Before energizing the system confirm:
✔ Equipment securely mounted
✔ Conductors and communications connected
✔ Covers installed
✔ Unused ports sealed
✔ Battery ON and communication ready
✔ Meter / CT configuration verified if used
Solis’s current installation and local-settings guides describe local Bluetooth connection, quick settings, battery setting, meter / CT setting, grid code setting, storage mode setting, and the ability to power the inverter on/off within the app settings flow.
Use the SolisCloud App.
Connect locally to the inverter via Bluetooth.
Set inverter time / date.
Select the correct battery model / battery settings.
Configure meter / CT settings as required.
Set the correct grid code.
Set storage / working mode.
Verify live values for PV, battery, load, and grid.
Confirm no battery communication alarms are present.
Solis’s current Bluetooth setup guide says first-time installer access is done in the SolisCloud app through More Tools → Local Operation → Connect with Bluetooth, then quick settings walk the installer through inverter time, battery model, meter placement, grid code, and storage mode. The same guide also describes battery settings, working modes, and information / alarm views.

✔ Installer Tip
This guide is the shortened companion to the longer Solis / Renon field guide. It is intentionally condensed in the same way as the GoodWe example you shared, which also compresses system overview, mounting, wiring, startup, and commissioning into a short installer-facing reference.
Always verify system design, conductor sizing, OCP, battery compatibility, grid code, and commissioning settings against the latest manufacturer documentation before final startup. Solis’s currently published manuals and app guides are still actively updated, including a US inverter manual dated March 2026 and SolisCloud commissioning guidance updated in late 2025 / early 2026, so using the latest revision matters here.
