| 36506 | Slave Address | U16 | | Slave ID of the EPM. The Inverters will start at one but the register values are at different numbers. |
| 36509 | Inverter Quantity | U16 | | Low byte is the number of PV inverters, high byte is the number of hybrids. |
| 36508 | Backflow Power | S32 | W | Power from the grid back to the inverters in Watts. Only applies when current control is OFF. |
| 36507 | CT Ratio | U16 | | Current transformer ratio. The secondary is always 1. Therefore if you have 1000:5A CTs, you will need to select 200 |
| 36511 | Fail Safe | U16 | | 0 = Fail Safe is OFF, 1 = Fail Safe is ON. G100/2 is here somewhere need to add later. |
| 36510 | Per Phase Limiting | U16 | | 0 = Per Phase Limiting is OFF, 1 = Per Phase Limiting is ON. G100/2 is here somewhere need to add later. |
| 36515 | PT Ratio | U16 | | Voltage transformer ratio. The secondary is always 1. Therefore if you have 1000:1V PTs, you will need to select 1000 |
| 36517 | Current Control | U16 | | 0 = Current Control is OFF, 1 = Current Control is ON. |
| 36513 | Transmit On/Off | U16 | | Default OFF. When ON, the EPM will stop controlling and replying to modbus, it will let you control and update connected inverters. |
| 36540 | On/Off | U16 | | 0 = ON, 1 = OFF. With this set to OFF, it will not control the inverters just monitor them. |
| 36541 | Site Password | U16 | | This is the password for the site. It is used to access the site settings and update the firmware. |
| 36543 | CT Direction | U16 | | 0 = forward, 1 = reverse |
| 36545 | Backflow Current | U16 | A | Current from the grid back to the inverters in Amps. Only applies when current control is ON. |
| 36546 | CT Polarity Check | U16 | | 0 = CT Polarity is correct, 1 = CT Polarity is incorrect |
| 36547 | Max Control Percent | U16 | % | 0-100. This is the maximum percentage of power that the EPM will control. If the inverter is producing more power than this, the EPM will not control it. |
| 36548 | Buffer | U16 | W or dA, depending on current control | Control deadband. Useful for unstable loads which are highly dynamic. Larger buffer = more stable but could sit at lower generation. |
| 36549 | Meter Select | U16 | | Primary meter type selection. Fixed at address 01. Low byte is meter type, high byte is meter location |
| 36539 | Meter2 Select | U16 | | Secondary meter type selection. Fixed at address 02. Low byte is meter type, high byte is meter location |
| 36550 | Clear Energy | U16 | | Zeros all energy counters. Requires confirmation. |
| 36551 | Control Protocol | U16 | | Communication protocol selection. 7E protocol works on all grid-tied inverters. Modbus broadcast does not work on all inverters (often need firmware update). 7E protocol is known to cause issues with hybrid inverters and cause PRO inverters to freeze. |
| 36552 | Generator Spinning Reserve | U16 | kW | Sets the spinning reserve power level for generator control. |
