1-1 On-line System

In on-line system, the product controls the charging and discharging in accordance with the on-line

commands which are determined by the programs in the utility power servers. The system operates identically to the

off-line system during periods when there are not any control commands from the utility.

* Operating on-line system requires a network adaptor (LJ-NA02) and network environments to access the server of the

utility power company.

* With the on-line system, the storage battery system operates giving priority to control commands from the utility.

* Select an operation mode when operating the off-line system. For details, see the explanation of 1-2 off-line system.

* As for the operations of the storage battery system via the programs of the server of the utility, contact the utility you are

contracted with.

1-2 Off-line System

Off-line 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 system. See 8-2 to see how to select.

* If you are a user of the on-line system, the off-line system operates when the programs are not issuing control

commands. The operation mode needs to be set.

* In order to correct the remaining battery level, charging and discharging operation are stopped once a day (From 3:00 to 3:30),

except in the back-up mode operation.

■Maximum Self-consumption Mode

• The product works in harmony with PV generation.

• By storing excess electricity in the product during the day, clean energy can be used around the clock even after

the sun goes down. This allows not only for the maximum utilization of clean energy, but also reduces the user’s

electricity bills.

* Energy is not sold to the utility while the product is discharging.

■Programmed Charge/Discharge Time Mode

• The customer can set the charge or discharge time on the product directly. The battery will be charged or

discharged only during this designated time. At other times it will not be charged or discharged.

* Energy is not sold to the utility while the storage battery is discharging.

* Set the charging/discharging duration. See 8-4 to see how to set it.

■Back-up Mode

• Always charge the storage battery until it is fully charged, after it has been completely charged it is in standby in

preparation for a power failure.

1-3 Stand-alone Operation

When power fails, the product can supply electrical power to the Stand-alone socket.

* Switch the operation mode manually to stand-alone operation when power fails. Switch the operation mode manually to grid

operation when the power comes back on. For details, see Chapter 5.

* Stand-alone operating time is dependent on the "battery remaining" and "connected load". See Chapter 8-3.

NOTICE:

* This is not an UPS (Uninterruptible Power Supply).

* The degree of deterioration and the remaining amount of power supply time.

* Stand-alone socket can not be used during Grid Operation.

* The amount of electricity that can be used in stand-alone socket is the maximum 2kVA.

supply in stand-alone socket is more than 2kVA, power supply will stop.

* The low power factor and high output distortion ratio equipment will not work.

* Power supplied from this product is not completely same as the commercial power supply.

* When the battery remaining level reaches zero, the "Stand-alone" operation will automatically stop.

The operating state of dimming lights may differ in the case of operating in grid mode and in the case of operating in stand-alone

mode.

The following equipments are supposed to be connected to the Stand-alone socket.

* LED light bulb/Florescent desk lamp/Incandescent lamp

* Modem

* Router

* Cellular telephony/Smart phone/Tablet computer

* Portable

TV/Radio

* Electric kettle

※When you connect one of the Electric kettle to Stand-alone Socket-outlet, the power consumption of the Electric kettle is

less than or equal to 2kW. When connecting a plurality of load, the sum of the load is to use the power consumption of the

Electric kettle of less than or equal to 2kW.

And the power output is stopped from the Stand-alone Socket-outlet because of a reduction of the remaining battery level,

there is a possibility that can not boil water completely in the Electric kettle.

1-4 Operational Temperatures

The Storage Battery System 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 the Storage Battery System.

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.

When these temperatures are exceeded, the battery storage system automatically shuts down.

The Storage Battery System operation is automatically restarted when its safe to do so.

factory default known as 'Maximum Self consumption Mode'.

We do not recommend charge/discharge mode that exceed the one per day cycle (i.e multiple daily full charge/

discharge) as the battery capacity will fall below 60% sooner than 10 years.

DRED provides a method by which a controlling authority, most likely a power supply company, can limit the amount

of power that the storage battery system can consume in comparison to its nominal full load power

consumption.

The aim is to reduce overall power consumption to the supply network at critical peak load times.

*DR mode is given priority from other modes.

■LJ-SK56A: Lithium-ion Storage Battery System

This system is equipped with two battery modules. This product incorporates a network adaptor that is connected to

the external server of the utility via the Internet.

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 Stand-alone 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-SK56A) to update the charging/discharging schedule and/or send information on the state of the

stored electrical power.
