MENU SYSTEM
Battery voltage was above the HIGH BATTERY CUT OUT VDC setting. This can be caused by the solar array or other charging source not being regulated. Check the controller for proper operation. Some controllers have a “equalize” setting which over-rides the normal operation, allowing the battery voltage to be unregulated. Return the controller to the “normal” setting and check for proper operation. If you are using NiCad type batteries, you will need to increase the HIGH BATTERY CUT OUT VDC setting. The inverter will automatically reset once the battery voltage has dropped 1.5 volts below the HBCO setting for a 12 VDC system, 3 volts for a 24 VDC system and 6 volts for a 48 VDC system

This setting controls when the inverter turns off due to a low battery voltage condition. The inverter will turn off only after this level has been reached for the period of time set by the following item. When the automatic generator control system is used, the generator will be started when the battery voltage has dropped below this value for 30 seconds continuously. This will occur even during the quiet time period. This setting is not temperature compensated

Sets the maximum amount of AC input current that the battery charger will use to charge the battery. This can be used to limit the charger output as well. The charger will “back-off” if the combination of AC loads and the charger reaches the AMPS AC setting of the AC INPUT connected to prevent overloading the source or tripping breakers. This process occurs automatically

OPERATION
TRANSFER TIME
While connected to the utility, the battery charger will be engaged. Some applications may want to allow the alternate power source solar, wind or hydro to recharge the battery instead of allowing the utility to provide the power. The only option is to program the SET MAX CHARGE AMPS AC menu item under the BATTERY CHARGING 10 menu heading to the minimum value, 1 amp AC, and set the BULK VOLTS and FLOAT VOLTS settings, also under the BATTERY CHARGING 10 menu heading, to a low value

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

OPERATION
Once the system has transferred back to the battery, the battery voltage will continue to increase if the power from the alternative source exceeds the loads. This can result in the battery voltage reaching the HIGH BATTERY CUT OUT VDC setting unless a charge control device limits the battery voltage. Note that the LOW BATTERY CUT IN VDC setting must be set below the external charge controllers regulation setting or the system would never transfer back to the battery. The best compromise involves setting the BULK VOLTS DC equal to the FLOAT VOLTS DC default value, and setting the LOW BATTERY CUT IN VDC setting to the default BULK VOLTS DC setting. Make sure the external charge controller is set slightly higher than the LOW BATTERY CUT IN VDC setting so that the voltage can be reached without the charging source shutting off
