Operation

AC Current Settings

The AC current settings control the amount of current that the inverter draws from the source(s). The amount of current is controlled by the grid or generator limit settings. These settings should be adjusted to match the size of the input circuit breaker or input conductor. In the system display, if the source is set to grid, the inverter uses the grid settings. If the source is set to gen, the inverter uses the generator settings.

¾This is intended to protect a generator or source that may not be large enough to supply enough current for both charging and loads. If the combined charging and loads exceed this setting, the inverter will reduce its charge rate and give priority to the loads. If the loads exceed this number on their own, the charge rate will be reduced to zero. The inverter is capable of supporting the source with power from the batteries. See the section entitled “Input Support” on page 17.

¾If multiple parallel inverters are installed with an AC source of limited amperage, the total combined amperage settings for all units must be less than the AC input circuit. The Configuration Wizard in the MATE3 can perform this calculation. However, the inverters do not perform this calculation. If the MATE3 or the Configuration Wizard are not used, it may be necessary to divide the input size by the number of inverters and assign an equal part of the amperage to each port.

AC Source Acceptance

The input source must meet the following specifications to be accepted:

¾230 Vac, ± 22 Vac (default setting), and

¾50 Hz, ± 5 Hz

When these conditions are met, the inverter will close its transfer relay and accept the input source. This occurs after a delay which is specified below. If the conditions are not met, the inverter will not accept the source. If it was previously accepted and then rejected, the inverter will open the relay and return to inverting power from the batteries.

¾If the source is set to grid, there is a connection delay of approximately 15 seconds. This time is not adjustable.

¾If the source is set to gen, there is a connection delay with a default setting of 0.5 minutes. This is intended as a generator warmup period. This item is adjustable.

NOTES:

Several items, external to the inverter, may prevent the inverter from accepting AC power even if electrical conditions are met. One is the high-battery transfer (HBX) mode, which is operated by the

system display. (See page 30 and the system display manual.) Another is the system display’s AC IN or AC INPUT hot key, which can turn off the input to all inverters. (See the system display manual.)

The inverter has additional criteria that control whether it sells power. The inverter may accept AC power but refuse to sell if the acceptance criteria are met, but the grid-interactive criteria are not. (See the section entitled “Selling” on page 24.)
