Open loop communication means the inverter and battery don’t directly exchange data, so you need to manually program voltage and current parameters into your inverter. This ensures safe and optimal operation of your Pytes battery, even without a closed-loop (CAN/RS485) connection.
Use the settings below to connect Pytes E-Box 48100R or V5 series batteries to any inverter using open loop communication.
Before You Begin:
-
This guide is for open loop setups — use it when your inverter does not support direct communication with Pytes batteries.
-
You must manually enter all voltage and current values into your inverter's battery settings menu.
-
If your inverter includes a temperature sensor, disconnect it, as temperature compensation is not used with Pytes batteries.
Step-by-Step Configuration Guide
Step 1: Set Charging Parameters
Enter the following charging values into your inverter:
| Setting | Value |
|---|---|
| Bulk/Absorb Voltage | 56.8V |
| Float Voltage | 56.0V |
| Absorb Time | < 15 minutes |
| Equalization | Disabled |
| Temperature Compensation | Disabled |
Step 2: Set Discharge and Protection Limits
Configure your inverter’s battery discharge settings as follows:
| Setting | Value |
|---|---|
| Low Battery Cut Out/Disconnect (LBCO) | 49.0V |
| Low Battery Warning | 50.0V |
| Low Battery Restart/Recovery | 51.0V |
| High Battery Cut Out/Disconnect | 58.0V |
| High Voltage Restart/Recovery | 56.0V |
Step 3: Set Current Limits
To avoid overloading the battery, apply the correct charge/discharge current limits based on the battery model and quantity:
-
E-Box 48100R:
Maximum Charge/Discharge Current = 50A * per battery -
V5 Series:
Maximum Charge/Discharge Current = 75A * per battery
Final Checks
-
Double-check all settings match the table above.
-
Disconnect any temperature sensor to disable temp compensation.
-
Save your inverter settings and reboot if required.
-
Monitor battery voltage and current to ensure safe operation.
