To change the AC INPUT POWER settings, Press
This allows the inverter to extract the maximum amount of power from a generator.
The inverter constantly monitors the Voltage from the generator and then applies maximum charge.
LEVEL 1 is the highest load to the generator while
LEVEL 6 is the minimum.
The factory default LEVEL is 1.
This setting only needs to be adjusted if there is a generator connected.
When a generator is running the generator will supply the AC Load first and the inverter charges the
batteries with any excess power created from the generator.
Always install a generator with a circuit breaker or contactor connection
Keep the circuit breaker off until the generator is running fully.
Turn of the circuit breaker before switching off the generator.

When to select Normal Sense?
UPS application –“The load is connected to the Grid most of the time”
•The grid “ESKOM” is the primary energy source and the system switches
to inverter mode when disconnected from the grid eg: “load shedding”.
•As soon the Grid is restored, the load re-connects to the GRID.
•The batteries will only charge when the Grid is present.
OR
Off-Grid application –“No Grid connection is available”
•The battery bank is the primary energy source and the inverter “IS NOT” connected to the grid.
•Renewable energy is used to charge the batteries.
•A generator can be connected to supply the system when needed.
If normal sense is required, press , the menu changes to Transfer Switch Time, section 7.7
If Solar Control Mode is required press , the menu changes to Solar Control Mode
7.4 Solar Control Mode
SOLAR CONTROL MODE EXPLAINED
When to select Solar Control Mode?
•The batteries are the primary energy source and the inverter “IS” connected to the grid.
“Grid assisted solar power system”
•The system uses renewable energy to charge the batteries.
•If the system is correctly sized the inverter will run mostly in inverter mode and will only connect to
the grid when the batteries are discharged to a set level.
•The system will run from the batteries for as long as the batteries can be sustained.
•When the battery voltage reaches the set “ Battery Run To Voltage”, the inverter connects the
load to the grid.
•When the battery reaches the set “AC Run To” voltage, the inverter transfers back to inverter
mode.
•The inverter charger should be switched off in order for the battery bank to be effectively charged
from the renewable energy source.
For Solar Control Mode the following setting must also be changed from the battery setup
menu:
Refer to section 6.1 Charging Rate
Battery Charging Rate
TURNED OFF - 0% of charge rate
Please note: Do not connect a generator when operating in the solar control mode.
