Page 4: How The System Works
* Operating remote-control system requires a network adaptor (LJ-NA02) and network environments to access the server of the utility power company. * With the remote-control system, the storage battery system operates giving priority to control commands from the utility. - Page 5 1-2 Stand-alone system Stand-alone system has three operation modes determined by the way the storage battery is used, the maximum self- consumption mode, programmed charge/discharge time mode, and back-up mode. Select an operation mode to use the storage battery. See 8-2 to see how to select. * If you are a user of the remote-control system, the stand-alone system operates when the programs are not issuing control commands.
- Page 6 1-4 Operational temperatures Battery Storage Systems MUST be installed in a location NOT exposed to direct sunlight continuously in regions where the minimum/maximum monthly mean temperature is always less than +40°C and greater than 0°C. Regions/site locations that do not meet both requirements are not suitable for Battery Storage Systems. On the odd occasions when the temperature exceeds +40°C or falls below -0°C, the battery storage system automatically gives high priority to preserving battery health by reducing battery output and extending the battery charging time.

A batteries capacity to maintain its charge 'State of Health' (SOH) slowly decreases over time due to the charging & discharging process. The following chart shows typical SOH decrease.

Page 8: System Overview
This system automatically updates its charging/discharging schedule based on instructions from the utility. In the event of a power failure, you can use the stored electrical power via a Back-up Socket-outlet. „ LJ-NA02: Network Adaptor The network adaptor facilitates the communications between the demand response server and the lithium-ion storage battery system (LJ-SK84A) to update the charging/discharging schedule and/or send information on the state of the stored electrical power. -

7-2 Date/Time Setting • Press "CLOCK (▼)" for three seconds in the normal state to switch to the date/time setting mode. • Each time you press "Menu (ENTER)", the active item will change in the order of year => month => day => hour => minute. The active setting value blinks. • Press “DATA (▲)” and “CLOCK (▼)” to change the value of the blinking digit. • Set the minute and press "MENU (ENTER)" to complete the date/time setting. • Once the date/time setting is complete, the set date/time data will be displayed in the order of year => month/day => hour/minute for two seconds each and then the normal display will be automatically returned to. * This product uses the date/time data to control the charging/discharging and to fine-tune the storage battery. Abnormal operations may result if the date/time is incorrect. Be sure to set the date/time accurately. * If not linked with the network adaptor, an error may occur in the date/time data depending on the precision of the internal clock of the storage battery system. Once a month, it is recommended that you confirm the time. -
