Inverter Configuration
NOTE |
---|
For system programming and configuration of parallel inverters, follow the procedure outlined in the inverter manual. |
Power On the Inverter. Press the inverter’s power switch. If battery power is present, the inverter will begin its startup process and all five indicator lights will illuminate.
Switch On AC and PV Inputs. Turn on the AC grid input breakers and PV input breakers to energize the system.
Check for Inverter Activation. If the inverter does not power up, confirm that it is receiving a valid DC input from the battery.
Verify Rapid Shutdown (RSD) Status. Ensure the Rapid Shutdown (RSD) switch has not been triggered. If triggered, the inverter will remain off and PV string voltages will stay at a safe level.
Keep AC Output Circuits Isolated (if applicable). If the system uses inverter stacking or multi-inverter configuration, keep AC output circuits isolated until stacking configuration is complete.
Wait for Full Inverter Activation. Allow the inverter to complete its boot sequence before beginning any configuration or system setup.
Inverter Quick Settings Overview
(If there are multiple inverters, repeat this procedure for each inverter.)
When commissioning the inverter for the first time, complete the Quick Setup in the following order:
Inverter Time → Meter Setting → Grid Code → Storage Mode → Battery Model
Inverter Time
Set the current date and time. The default setting will follow your mobile device.
CT / Meter Setting
Select CT or Meter (Solis supports Eastron 3-phase, auto-detected meters).
Choose the installation location: Grid side, Load side, or Grid+PV.
Set CT direction: use Forward if installed correctly; use Reversal if polarity is reversed.
Set CT ratio: default is 60. If using a different CT, adjust manually. If using a meter, set the ratio accordingly.
Grid Code
Select the region, either the USA or Canada.
Select UL-240V-18 for IEEE 1547-2018 or R21P3-240 for California Rule 21.
Storage Mode
Choose the system’s energy flow priority:
Self-Use, Selling First, or Off-Grid.
NOTE |
---|
The load is always the inverter’s priority. Self-use mode makes the second priority charging the battery. Selling First mode makes the second priority exporting excess PV power. Only one mode can be active at a time. |
Battery Settings
Choose the connection method: 1 Batt 2 DC or 2 Batt 1 DC
Select the battery brand and model. If not listed, choose General_LiBat_HV
Set the maximum charge/discharge current (limiting is typically not required)
For dual-battery systems using the same settings, enable "Batt2 Settings follow Batt1."
Battery Settings Menu
The Battery Settings menu on the inverter interface allows for more detailed battery parameters to be adjusted. These settings help fine-tune charge behavior, protect battery health, and optimize system performance.
The table below outlines recommended configuration values for each setting to ensure safe and efficient operation when using the AES 210HV battery. Adjustments may be made based on project-specific requirements.

Setting | Recommended Value | Notes |
---|---|---|
Max charge current | 100 A | Matches typical Solis inverter capability (Do not exceed cabinet limits). |
Max discharge current | 100 A | Keeps battery within safe continuous discharge range. |
Over discharge | 10-20% | Preserves battery life by avoiding deep discharge. |
Recovery | 20-30% | Set ~10% above over discharge to avoid cycling instability. |
Force charge | 10-20% | Same as Recovery. Only active under grid charge priority conditions. |
Max charge SOC | 100% | Leaves a small buffer at the top to reduce battery stress and prolong life. |
NOTE |

Dual Inverter, Single Battery Cabinet Applications When using two inverters with one AES 210HV cabinet, limiting each inverter’s charge and discharge current may be necessary to avoid exceeding the cabinet’s capability. The combined output of both inverters must not exceed 157 A, which is the cabinet’s C/2 continuous current limit. If the inverters can deliver more than this combined current, adjust their settings to stay within the battery’s safe operating range. |
