generated from natural sources and from fuel cells.
Energy conservation is achieved through the use ofrechargeable batteries that store generated power that isused when needed. The core of this energy management

The Superiority

The Solar Age
PV systems are environmentally friendly and economical,
making them ideal for generating power. However, there are
currently a host of issues that need to be resolved, from the

3 Loss due to solar cell characteristics
Internal losses in a solar module are varied and linked to the imbalances between solar cells. Voltage imbalances are particularly apt
to occur when PV strings are connected in parallel. Current ﬂowing from the higher voltage PV string to a lower voltage PV string
results in a voltage drop at the inverter input of the system.

A multi-MPPT system controls voltage loss.

Dirt on the surface of the solar panels impedes the system's ability to receive sunlight. Rainfall does not wash away some types of dirt, so the

Actual output power

Typically, the conversion eﬃciency of solar cells decreases as the temperature rises. More power isgenerated on cool days than hot days when there is a great deal of irradiation.

7 Loss due to conversion eﬃciency of inverter
8 Loss due to shutdown caused by malfunctions

6 Loss due to intermediary devices
Diodes are installed in junction boxes and panel boards to prevent reverse current damage to solar cell
modules. However, the operating power of these diodes and the heat generated when they run results in aloss of power. Even more voltage conversion loss occurs when booster units are used. The anticipated
nameplate capacity will not be attained if the overall eﬃciency of the system is not taken into consideration.

Built-in junction boxes eliminate loss due to intermediary devices.

longer it takes to detect a malfunction and complete repairs, the greater the decrease in power generated.

Even when panels malfunction, multi-MPPT systems continue to generate power.

The Superiority

Multi-MPPT systems reduce power loss
Since a multi-MPPT system can control the voltage input of each string, there is no need to adjust thecapacity as with central systems. Installation is simple, there is no need for junction boxes, booster units,
or any other such intermediary devices. Also, input connections can be made directly to the inverter
without causing intermediate losses. Multiple MPPT makes it possible to combine different types of solar
panels. Since devices can now be installed in locations that were previously impossible, installers canmake the most effective use of roof surface area for the generation of electric power.

In our multi-MPPT system, each string is independent of the other strings. Even if some panels ina particular string malfunction, the other strings remain unaﬀected.
Since strings can be turned on and oﬀ individually, the malfunctioning string can be electrically isolated.

Features
Monocrystalline

Although monocrystalline solar cells excel in performance and reliability,
substrate prices are high.

Polycrystalline

These solar cells have polycrystalline silicon substrates. Although conversion rates are lower than
monocrystalline panels, these panels dominate the market because they are cheaper and easier to make.

Amorphous

This type of solar cell uses an amorphous silicon ﬁlm on a glass substrate. Although conversion
eﬃciencies are less than crystalline systems, they can be mass produced for large surfaces.

Multi-contact typeSolar cells with multiple layers of silicon ﬁlm. This method uses smaller amounts of silicon and lends itself to the mass productionof large surface areas. Since these panels absorb a wide band of wavelengths, they are more eﬃcient than amorphous solar cells.

CIS system
CIGS system

Solar cells made using copper, indium, gallium, selenium, and other compounds. They are thin so they conserve resources
and are easily mass produced. They oﬀer high performance, so a great deal of work is being done on their development.

Also suitable for large-scale generation!
With our multi-MPPT systems, panel generation data can be collected for each string so decreases in
output can be detected early on. Also, since exactly which panel is defective can be identiﬁed,
maintenance can be performed without delay. Therefore, loss is minimized when the system is shut
down for routine maintenance or when a malfunction occurs.

Hybrid Solar Inverter with Embedded Battery

Four Operating Modes ‒ Max Power Export, Economy, Home Backup and Peak Cut❶ Max Power Export Mode

The most economical mode of electric power is through the charging and discharging of storage batteries.
This mode prioritizes selling PV-generated power during the day. It uses the power stored in the battery tocover the household load in the evening when demand is high. The battery is charged overnight when powerrates are low to compensate for the power used during the daytime and the evening.
①②
After solar power is generated
and used for the householdload, surplus power is sold tothe power company.

❸ Home Backup Mode
This mode was designed for areas that are subject to a power outage to keep the storage batteries fully.
It is charged at all times by using surplus PV-generated power during the daytime and purchasing power from thepower company at night. After charging the storage batteries fully, it is standing by for a power outage.
5

Power is purchased from thepower company and used in thehome, while power is stored in thestorage battery.

This mode increases energy savings by increasing self-generated power, thus reducing powerpurchased from the grid. This mode stores in the storage batteries surplus PV-generated power during
the daytime and discharges power in the evening and overnight to cover the household load.

After supplying the householdload, surplus PV power is used
to charge the storage battery.
Any excess power may be
exported to the powercompany.

The system performs surplus orforced charging. During excess
charging, the battery is charged if
solar power generation exceeds
demand power generation. Duringforced charging, the battery is
charged from solar power
generation and grid power
generation. (Up to 1.5 kW)

This mode cuts the peak during the speciﬁed time slot. The battery discharges in case the purchasing
power exceeds the set value beforehand.

Discharge up to
max. 2.0 kW

This mode minimizes use of “peak electricity” and “purchased electricity”
by charging the storage batteries at night when utility rates are low
and evening to run connected electric appliances.

We are developing new products with Geli
Solar inverter manufacturer Tabuchi Electric has partnered with Geli, a software provider for battery
storage and microgrids, to provide a residential solar-plus-storage solution to accelerate the residential
solar market.
Through this partnership, a solar-plus-storage solution will be created by combining Geliʼs softwarewith Tabuchiʼs hardware to optimize grid performance.
Tabuchiʼs Eco Intelligent Battery System (EIBS) residential solar-plus-storage solution integrated with
Geliʼs Energy Operating System software will systematically manage energy ﬂow from the home to thegrid when connected to solar installations and smart home devices such as smart thermostats andpool pumps.
About Geli
Geli provides software and business solutions to design, connect, and operate energy storage and microgrid
systems. Geliʼs suite of products creates an ecosystem where project developers, OEMs, ﬁnanciers, and project
operators can deploy advanced energy projects using a seamless hardware-agnostic software platform. Geli ESyst™
is an online design tool for the analysis and design of energy storage and microgrids. Geli EOS™, short for Energy
Operating System, is a software platform that allows for advanced functionality of any OEM equipment via Geli
Energy Apps & Geli Energy Drivers. Geli GENI™, which stands for Global Energy Network Interface, is the portal
through which systems are monitored for performance and can be aggregated for virtual power-plant services.
