BATTERY SELLING (17) MENU HEADING

Note: See the battery section of this manual for recommended settings for different battery types.

Set Battery Sell

volts DC 13.4

12 VDC models

Range: 5.0 to 16.0

Set Battery Sell

volts DC 26.8

24 VDC models

Range: 10.0 to 32.0

Set Battery Sell

volts DC 53.6

48 VDC models

Range: 20.0 to 64.0

Sets the level to which the batteries will be discharged when power is being sold from the batteries to the grid. This is only used if the SELL mode is enabled and the GRID USAGE TIMER (18) is programmed. This setting will not be adjusted for the battery temperature if the temperature sensor is installed.

Set Max	Sell
amps AC	30

Standard models

Range: 01 to 35

Set Max	Sell
amps AC	15.0

“E” models

Range: 01 to 18

Set Max	Sell
amps AC	35

“J & K” models Range: 01 to 40

Set Max	Sell
amps AC	16.5

“W” models

Range: 01 to 18

Sets the maximum AC amps allowed to be delivered to the utility grid from a solar array and/or the batteries during utility interactive operation. This is only used if the SELL mode is enabled. If batteries are being “sold” into the utility grid, this setting together with the SET BATTERY SELL VOLTS DC setting determines the depth of discharge the batteries will experience. Note: The default setting will vary between models with different continuous output power ratings.

INFORMATION DISPLAY

The following information is displayed as additional Menu Items.

See menu 9 to enable SELL mode. Make sure LBX is above LBCO volts.

GRID USAGE TIMER (18) MENU HEADING

The Grid Usage Timer selects when power may be drawn from the utility grid for battery charging. It is used only when either the FLT or SELL modes are selected in the SET GRID USAGE menu item under the INVERTER SETUP (9) menu heading. Utility Power must be connected to the AC1 for this timer to be operational.

Start Charge		End Charge
time	21:00	time	21:00
All Models		All Models
Range: 00:00 to 23:50		Range: 00:00 to 23:50

FLT mode: After the START CHARGE TIME, the inverter turns on the battery charger, connects the utility grid and powers the AC loads from the utility grid and charges the battery to the FLOAT VOLTS DC setting. At the END CHARGE TIME, the inverter disconnects from the utility grid and powers the loads from the battery.

SELL mode:

•With the GRID USAGE TIMER enabled (the START CHARGE TIME is different from the END CHARGE TIME), the inverter will charge the battery to the FLOAT VOLTS DC setting at the START CHARGE TIME. After the END CHARGE TIME, the inverter turns off the battery charger and begins to “sell” power into the utility grid from the battery (or any other DC sources available and connected to the batteries) to the SELL VOLTS DC setting. The current will be limited to a maximum level controlled by the MAX SELL AMPS AC menu item setting under the BATTERY SELLING (17) menu heading.

•With the GRID USAGE TIMER disabled (the START CHARGE TIME beginning time is equal to the END CHARGE TIME), the inverter will use the utility grid (or any other DC sources available and connected to the batteries) to maintain the batteries to the FLOAT VOLTS DC setting.

In the SELL mode, battery voltage will be held near the SET BULK VOLTS DC setting for the adjustable ABSORPTION TIME period setting after an AC failure or upon encountering a BULK CHARGE TRIGGER TIMER event.
