Operation
NOTES:
The Support, Offset, and
Any AC fluctuations that are accepted by the inverter will be transferred to the output. The loads will be exposed to these fluctuations. It may not be advisable to install senstive loads under these conditions.
In this mode, the Radian inverter’s maximum charge rate is limited to 20 Aac (80 Adc).
While charging, the charger will not go silent (see page 22). After completing the charge, it will remain in the Float charging stage unless this generator is stopped (either automatically or manually) or AC input power is otherwise removed.
Support
This mode is intended for systems that use the utility grid or a generator. In some cases, the amount of current available from the source is limited due to size, wiring, or other reasons. If large loads need to be run, the Radian inverter augments (supports) the AC source, adding inverter and battery power to ensure that the loads receive the power they demand.
In the MATE3 system display, the Grid Input AC Limit dictates the maximum AC draw for the Grid input. The Gen Input AC Limit sets the maximum draw for the Gen input. This function takes effect if the AC draw on the appropriate input exceeds its setting.
CHARGING:
In this mode, when the charger is enabled, the Radian will use the AC source to charge the battery bank. (See page 20.) It will proceed through the entire battery charging cycle. After the end of the Float timer, it will continue to alternate between Silent and
BENEFITS:
The large loads on the system can be powered while staying connected to the input, even if the input is limited. Battery power prevents overload of the input source, while at the same time limiting the amount of battery power used.
In this mode, the inverter will offset the loads with excess renewable energy if it is available from the batteries. (See page 19 for more information on the Offset function.)
This mode has a programmable delay time which will allow an AC source to stabilize before connection. In the MATE3, this menu item is Connect Delay. It is available in either the Grid AC Input Mode and Limits or the Gen AC Input Mode and Limits menu, depending on which input is being programmed.
NOTES:
IMPORTANT:
If the AC loads exceed the amperage limit setting, the inverter will draw energy from the batteries. If the loads are sustained, the batteries may discharge to the point of Low Battery
The
Because the inverter limits the current draw from the AC source, it will reduce the charge rate as necessary to support the loads. If the loads equal the amperage setting, the charge rate will be zero.
If the AC loads exceed the amperage setting, the charger will begin operating in reverse. It will take power from the batteries and use it to support the incoming AC current.
