Notes on Usage
This Hybrid Solar Inverter uses the electric power generated by the sun during the day. Surplus power
is continuously stored in the lithium-ion storage batteries. (Charging differs according to the operating
mode.) The power stored in the storage batteries is used to stabilize the daytime power supply as well
as a nighttime power source at night.
After DC power from the PV panels is converted into AC power by the Hybrid Solar Inverter, it is
connected to the commercial power grid and used to power electric appliances.
Moreover, DC power stored in the storage batteries is used to drive the modes below, so daily
operation is not necessary.
Grid-tied Operation Page 14
■MAX POWER EXPORT Mode
Daily operation is not necessary.
Storage batteries are charged by the commercial power grid at night. Power stored in the storage
batteries is used during the daytime to cover any PV system generation shortages and avoid peak
rate grid charges.
■ECONOMY Mode
Surplus power generated by the PV system is not only sold to the power company, but it is also
stored in the storage batteries for use at night.
■HOME BACKUP Mode
Storage batteries are kept fully charged at all times as a safeguard against power outages on the
commercial power grid.
Operating modes can be selected according to
personal lifestyle.
As long as the solar panels are generating power or the storage batteries retain a charge, the inverter
will keep running in the event of an outage on the commercial power grid by automatically switching
to stand-alone operation (Page 20).
Carefully read the precautions on stand-alone operation (Page 18) before use.

Modes and Mechanisms
HOME BACKUP Mode keeps the storage batteries fully charged at all times. Once charged, the system goes on
standby as a safeguard against power outages on the commercial power grid.
The display may not show that the storage batteries are fully charged due to a margin of error.
Use the inverter as an emergency power supply for instances such as rolling blackouts, etc. Use of the Storage
Mode is recommended since it keeps the storage batteries fully charged at all times. If an outage is anticipated
while using the inverter in another mode, you can switch to the Storage Mode ahead of time and minimize the
impact of the outage by having the storage batteries fully charged.
The following three modes are available during grid-tied operation. To switch modes, see the "Remote Controller"
section (Page 10) of the User's Manual.
Surplus PV-generated power is used to charge the storage batteries.
Any power that cannot be stored in the storage batteries is sold.
Power is discharged from the storage batteries. If there is not enough
power coming from the PV system and storage batteries, power is
purchased from the power company.
Power is sold
MAX POWER EXPORT Mode
When power is contracted

MAX POWER EXPORT Mode minimizes use of “peak electricity” and
“purchased electricity” by charging the storage batteries at night when
utility rates are low and discharging the stored power during the day
and evening to run connected electric appliances.
ECONOMY Mode ECONOMY Mode minimizes the amount of purchased electricity
purchased from the grid by utilizing PV-generated power during the day, in the
evening, and at night.

Notes on Usage Before Using the Inverter for the First Time
The rated output of solar panels is based on certain conditions. The actual amount of output will vary
according to the intensity of sunlight, surrounding temperature and the direction and angle at which the
panels are installed. Therefore, even on clear days, the rated output may not always be generated. On clear
days, the generated power should be about 70 to 80% of the rated output.
Preparations
IMPORTANT INFORMATION to KNOW
■Generated power
•The very first time the inverter is used, it can be started by pressing the [RUN/STOP] button.
•Once the inverter starts up, it runs automatically in the set operating mode according to the amount of
sunlight, time of day, battery charge, etc.
•At night, when it is raining, or when inverter output is insufficient to run connected appliances because the
battery charge is low, power is automatically supplied from the commercial power grid.
■Daily operation is not necessary.
Although the inverter is automatically supplied by stored battery power when a power outage occurs, the
power supply is briefly interrupted when the inverter switches over to stand-alone operation.
Once the commercial power grid operation is restored after an outage, the inverter automatically resumes
grid-tied operation.
■When a power outage occurs, the inverter automatically engages stand-alone operation.
Before using the inverter for the first time, have the installer perform the operations described below
in the “Preparations” and “System Startup” sections.
The Hybrid Solar Inverter is for outdoor use.
Check the operating status of the inverter.
Set the grid-tied breaker in the Main Panel to the ON position.
System Startup
When the grid-tied breaker is set in the ON position, the display
indicates that grid-tied operation has been manually stopped as
shown in the image on the right.
When “STAND-ALONE STOP” is displayed on the screen, press and hold the
[RUN/STOP] button for 5 seconds or more, and confirm that the operating
status changes to “MANUAL GRID STOP.”
Press the [RUN/STOP] button. “GRID CONNECT→” appears on the

Stand-alone Operation
(In a Power Outage)
Stand-alone Operation Precautions
During stand-alone operation, power is supplied only to the stand-alone outlets. During a power outage, other outlets cannot be used.
• Use the stand-alone outlets.
Power output from the PV system and storage batteries can be unstable due to weather conditions and charge. If output
drops, stand-alone operation stops automatically.
• Electric appliances running off stand-alone operation may shut off.
The backup power provided by the inverter is envisioned to supply electricity to run refrigerators, TVs, lighting fixtures, laptop
computers and cellphones. Many lighting fixtures and refrigerators have protective circuits that trip and prevent the product from
running in case there is a surge in current when the power is turned on. Do not connect air conditioners, washing machines, and
other appliances to stand-alone outlets that may draw a large current when turned on.
• When power is supplied to electric appliances connected to the stand-alone outlets, inrush current may trip
protective devices and prevent the appliances from running.
• If stand-alone operation automatically stops due to high power consumption, the electric appliances that were
running stop temporarily. Although stand-alone operation resumes automatically when power consumption decreases,
connected appliances that have protective circuits are prevented from resuming operation.
The maximum amount of current that can be drawn during stand-alone operation is 16.6 A. Only connect electric appliances
that consume less than 16.6 A. Though this will vary by appliance, a maximum of 16.6 A at 120V AC equates to somewhere
between 1.5 - 2.0 kVA. Moreover, 0.1 - 0.3 kW are needed to keep the inverter running.
If the electric appliances connected to the stand-alone outlets consume more power than is generated by the PV system and
supplied by the storage batteries, stand-alone operation shuts down.
Many lighting fixtures and motor-driven appliances (e.g., vacuum cleaners. refrigerators, dryers, etc.) draw a large current when
turned on, and consequently will not run. Using these appliances may also trip protective circuits and keep them from running.
• There is a limit to the amount of power that can be drawn at one time.
• Stand-alone operation is automatically engaged if a power outage occurs.
Circuitry has been designed to enable lighting fixtures, communication equipment and other electric appliances
to be used in the event of a power outage without having to unplug and plug them back in again.
During the morning and daytime hours, the solar panels and storage batteries cooperatively supply the electric power
necessary for household consumption. Surplus power is used to charge the storage batteries. During the evening and
nighttime hours, power is supplied by the storage batteries.
■Recharging the Storage Batteries using the Solar Panels
■Electric Appliances Connected to Stand-alone Outlets during
an Outage Can Be Used without Plugging Them Back in.
Electric power generated by the solar panels can be efficiently stored in the storage batteries. This is useful during
extended power outages that last several days.
* Battery charge will vary according to the amount of power generated by
the PV system and the amount of household consumption.
