OPERATION

SELLING POWER - STORED IN THE BATTERIES

Power stored in the batteries can also be sold into the utility grid. This can be used together with the solar array or alone without a solar array. The inverter can be programmed to sell the energy in the batteries at a specific time and then to recharge the batteries at another time. Both the discharge level and discharge rate can be adjusted to control the battery selling process.

Selling the power stored in the batteries can be used to level the output of the combined solar array and battery system. This is beneficial during conditions of cloudy weather when the solar array output will vary with each cloud that passes over. To set-up this ability, adjust the SET BATTERY SELL VOLTS DC menu item under the BATTERY SELLING (17) menu heading for the maximum discharge voltage level acceptable. The SET MAX SELL AMPS AC menu item should be set for the expected maximum output of the solar array. Next, access the GRID USAGE TIMER (18) menu heading to allow setting of the time period that the battery will be allowed to recharge during by adjusting the SET START CHARGE TIME and SET END CHARGE TIME menu items. Outside of this time period, the inverter will sell the power stored in the battery to the utility grid until the voltage reaches the BATTERY SELL VOLTS DC setting.

This mode can use the battery to maximize the output of the system during a specific period of time. An example of these setting follows:
