These run time estimates assume continuous full-power discharge and operation within safe continuous discharge parameters. Final performance should match the site's energy demand and load profile.

System Scalability – One Inverter, One AES Cabinet

Each Solis S6-EH3P inverter is paired with one AES Cabinet.

In this setup:

• 104 / 160 / 209 kWh of usable backup energy per inverter

• Discharge power limited by the inverter model (30–60 kW)

• Up to six inverters can be connected in parallel on the backup side, providing up to 180-360 kW of continuous backup power and approximately 624–1,254 kWh of total backup energy (6 × 104 kWh / 6 × 157 kWh / 6 × 209 kWh).

Grid-Tied (Non-Backup) Scalability

The number of inverters or batteries is unlimited for non-backup use. Each inverter runs independently, allowing systems to scale as large as needed for energy shifting, peak shaving, or other grid-interactive applications.

DC Battery Wiring – One Inverter, One AES Cabinet

Each Solis S6-EH3P inverter has two battery input terminals, each rated up to 80 A for the 30-50K models and 84 A for the 60K model. The AES Cabinet connects using:

• Two positive and two negative #4 AWG conductors

• Each conductor is protected by a 70 A fuse in the AES Cabinet’s built-in DC distribution box

This setup ensures balanced current flow to each of the inverter’s internal DC/DC converters and, depending on the inverter model, supports continuous discharge of 30-60 kW.

Communication – One Inverter, One AES Cabinet

In a one-to-one configuration, the AES Cabinet communicates with the Solis inverter through the LYNK II Gateway, enabling real-time, closed-loop control.

• Use standard CAT6 or higher Ethernet cables, wired in a straight-through configuration with RJ45 plugs on both ends.

• Connect one cable from the LYNK II’s CAN port to the Solis inverter's BMS1 port.

• Connect a second cable from the LYNK port on the LYNK II Gateway to the J3/J4 port on the AES Cabinet’s High Voltage Box. On most AES Cabinets, a CAT6 cable is already connected to the J3 port on the AES Cabinet’s High Voltage Box and is accessible from the LYNK II.

This communication link enables the inverter to receive live battery data, including state of charge, voltage, current, temperature, and charge/discharge limits, for safe, accurate, and optimized operation.

One Inverter, Two AES Cabinets

CAB-106, CAB-160, and CAB-210 Configurations

When two AES Cabinets are paired with a single Solis S6-EH3P inverter, the AES Cabinets’ maximum continuous current limit is 157 A, operating within their rated 104 / 156 / 208 kW continuous output limit. Actual discharge performance depends on the inverter model’s battery-side power capacity, as shown below.

Full Load Duration (Operation at Max Power)

These run times assume continuous full-power discharge at the inverter's rated limit. While the inverter determines the maximum power output, the dual-cabinet setup extends runtime. Dual cabinets increase total stored energy and are ideal for longer-duration backup or deeper cycling in time-of-use and peak-shaving applications.

System Scalability – One Inverter, Two AES Cabinets

Each Solis S6-EH3P inverter can be paired with two AES battery cabinets, doubling the usable energy per inverter while maintaining discharge power based on inverter size.

In this setup:

• 208 / 314 / 418 kWh of usable backup energy per inverter (2 × 104 kWh / 2 × 157 kWh / 2 × 209 kWh)

• Discharge power limited by the inverter model (30–60 kW)

• Up to six inverters can be connected in parallel on the backup side, supporting 198-360 kW of backup power and approximately 1.254–2.5 MWh of total backup energy (6 × 208 kWh / 6 × 314 kWh / 6 × 418 kWh).

Grid-Tied (Non-Backup) Scalability

For grid-tied applications, the number of batteries or inverters is not limited. Each inverter operates independently, enabling large-scale deployments for energy arbitrage, load shifting, or demand charge reduction without backup power constraints.

DC Battery Wiring – One Inverter, Two AES Cabinets

When connecting two AES battery cabinets to a single Solis S6-EH3P inverter, each cabinet is wired to a dedicated battery input terminal:

• Battery 1 connects to the inverter’s BAT1 terminals

• Battery 2 connects to the inverter’s BAT2 terminals

The inverter’s integrated dual DC/DC converters are independently fused and control each input, allowing the inverter to manage each battery cabinet separately while balancing charge and discharge as needed.

Always follow NEC guidelines for conductor sizing, 1,000 Vdc insulation rating, proper torque values, and verify polarity before energizing the system.

Communication – One Inverter, Two AES Cabinets

Each AES battery cabinet uses its own LYNK II Gateway for closed-loop communication with the Solis inverter in a two-to-one configuration. The inverter’s two BMS ports (BMS1 and BMS2) allow it to communicate with each battery independently.

• Use standard CAT6 or higher Ethernet cables, wired in a straight-through configuration with RJ45 plugs on both ends.

• Connect one cable from LYNK II #1 CAN port to the Solis inverter’s BMS1 port. Connect another cable to LYNK II #1’s LYNK port to the J3/J4 port on the AES Cabinet’s High Voltage Box. On most AES Cabinets, a CAT6 cable is already connected to the J3 port on the AES Cabinet’s High Voltage Box and is accessible from the LYNK II.

• Connect a third cable from LYNK II #2 CAN port to the Solis inverter’s BMS2 port. Connect a fourth cable from LYNK II #2’s LYNK port to the J3/J4 port on the AES Cabinet’s High Voltage Box.

This setup enables the inverter to independently manage and monitor both battery cabinets, receiving real-time data for state of charge, voltage, current, temperature, and charge/discharge limits from each LYNK II Gateway. Two independent LYNK II Gateways ensure precise, safe, and optimized performance across both battery units.

Two Inverters, One AES Cabinet

CAB-106, CAB-160, and CAB-210 Configurations

When paired with two Solis S6-EH3P inverters, the AES Cabinet may limit the inverters to a maximum continuous output of 52/78/104 kW. Actual discharge performance depends on the inverter model’s battery-side power capacity, as shown below.

These run time estimates assume continuous full-power discharge and operation within safe continuous discharge parameters. Final performance should match the site's energy demand and load profile.

System Scalability – Two Inverters, One AES Cabinet

Two Solis S6-EH3P inverters are paired with one AES battery cabinet.

In this setup:

• 104/157/209 kWh of usable backup energy between two inverters

• Discharge power is limited by the total inverter capacity or battery power limitation (max 52/78/104 kW)

• On the backup side, up to six inverters can be connected in parallel, providing 192.6-300 kW of continuous backup power and approximately 312 / 471 / 636 kWh of total backup energy (3 × 104 kWh / 3 × 157 kWh / 3 × 209 kWh).

Grid-Tied (Non-Backup) Scalability

The number of inverters or batteries is unlimited for non-backup use. Each inverter runs independently, allowing systems to scale as large as needed for energy shifting, peak shaving, or other grid-interactive applications.

DC Battery Wiring – Two Inverters, One AES Cabinet

Each Solis S6-EH3P inverter has two battery input terminals, each rated up to 80 A for the 30-50K models and 84 A for the 60K model. The AES Cabinet connects using:

• Two positive and two negative #4 AWG conductors to each inverter.

• Each conductor is protected by a 70 A fuse in the AES Cabinet’s built-in DC distribution box.

This setup ensures balanced current flow to each inverter’s internal DC/DC converter and supports up to 30-60 kW continuous charge/discharge depending on the inverter model.

Communication – Two Inverters, One AES Cabinet

In a two-to-one configuration, a LYNK II Gateway is required for each inverter to enable real-time, managed (closed-loop) control. The AES Cabinet communicates with one Solis inverter through one LYNK II Gateway (may be included with the battery cabinet), and with a second Solis inverter through a second LYNK II Gateway.

Wiring

• Connect one cable from LYNK II #1 CAN port to the Solis inverter #1’s BMS port. Connect a second cable from LYNK II #1’s LYNK port to the J3 port on the AES Cabinet’s High Voltage Box. On most AES Cabinets, a CAT6 cable is already connected to the J3 port on the AES Cabinet’s High Voltage Box and is accessible from the LYNK II.

• Connect a third cable from LYNK II #2 CAN port to the Solis inverter #2’s BMS port. Connect a fourth cable from LYNK II #2’s LYNK port to the J4 port on the AES Cabinet’s High Voltage Box.

The LYNK II communication link enables the inverter to receive real-time battery data, including state of charge, voltage, current, temperature, and charge/discharge limits, ensuring safe, accurate, and optimized operation.

NOTE

You can use a splitter/combiner, as shown below, to connect two LYNK II Gateways to the J3/J4 ports on the AES Cabinet through a single cable.

Configure LYNK II

1. Start LYNK ACCESS 2.5.0 or later and update both LYNK II Gateways to firmware to 2.5.0 or later.

2. Connect to the first LYNK II device. From the LYNK ACCESS software’s LYNK tab, open the Cabinet Settings tile, enable Multi-LYNK, and set it as Primary.

3. Connect to the second LYNK II device, enable Multi-LYNK and set it as Secondary.

To confirm the system is working correctly, check the battery charging current values on the inverter. If values are 50% of the max, then the 2:1 Multi LYNK configuration is successful.

This setup enables two inverters to manage and monitor the battery cabinet, receiving real-time data for state of charge, voltage, current, temperature, and charge/discharge limits from each LYNK II Gateway. Two independent LYNK II Gateways ensure precise, safe, and optimized performance with dual inverters.
