4. Operation
4.1 Powering On/Off
- Ensure all wiring connections are secure and correct.
- Switch the DC input breaker to the ON position.
- Switch the AC output breaker to the ON position.
- Press the Power On/Off switch on the inverter to turn it on.
4.2 LCD Display and Function Buttons
The inverter features an LCD display and function buttons for monitoring system status and configuring settings.
4.3 System Settings
To access and modify settings, press and hold the ENTER button for 3 seconds. Use the UP and DOWN buttons to navigate through programs and values, and ENTER to confirm selections.
Program 01: Output Source Priority
This setting determines the priority of power sources for your loads.
- SOL (Solar First): Solar energy powers loads as first priority. If solar is insufficient, battery energy supplies power. Grid energy is used only if solar is unavailable or battery voltage drops below a warning level.
- UTI (Utility First): Utility grid is the primary power source.
- SBU (Solar-Battery-Utility): Solar power first, then battery, then utility.
- SUB (Solar-Utility-Battery): Solar power first, then utility, then battery.
Program 05: Battery Type
Select the type of battery connected to the inverter. Options include AGM, Flooded, User-defined, and Lithium. For Lithium batteries, consult the lithium battery compatibility list and set the relevant communication protocol.
Program 14: Charger Source Priority
This setting determines the priority of charging sources for your battery.
- CSO (Solar First): Solar energy charges the battery as first priority. Utility charges only when solar energy is not available.
- CUE (Grid First): Grid energy charges the battery as first priority.
- SNU (Solar and Grid): Both solar and utility energy charge the battery.
- OSO (Only Solar): Only solar energy will be the charger source, regardless of utility power availability.
Program 19: Bulk Charging Voltage (CV voltage)
Set the bulk charging voltage from 48V to 58.4V. This setting is active when Program 05 is set to 'User-defined'.
Program 20: Floating Charging Voltage
Set the floating charging voltage from 48V to 58.4V. This setting is active when Program 05 is set to 'User-defined'.
Program 21: Low DC Cut-off Voltage
Set the low DC cut-off voltage from 40V to 48V. This setting is active when Program 05 is set to 'User-defined'.
Program 23: AC Output Mode (Parallel Operation)
When units are used in parallel for a single-phase system, select "PAL". For parallel operation in a three-phase system, select "3P1" for L1 phase, "3P2" for L2 phase, and "3P3" for L3 phase.
