About Lumen
Lumen by inverSOL is an intelligent, renewable energy system that provides you with greater energy
independence. The system captures and stores solar energy to power critical household appliances
regardless of the state of incoming utility power. Its unique hybrid DC/AC coupled design lowers your
utility bills, provides backup power, and reduces your carbon footprint.
Lithium NMC (LiNMC) battery cells used in Lumen are manufactured by LG and are assembled into
packs that are validated and produced with uncompromised safety and quality control. Your Lumen
battery stores excess solar energy produced during the day for use at night. In addition, the energy
storage system assures that your critical appliances have power 24/7/365.
Your Lumen also includes a powerful computing and communications platform that is the brain of
the system. The inverSOL proprietary algorithms ensure that virtually all solar energy produced is
consumed at some point during the day. The user experience is enhanced through an interactive
touch display and smartphone app. Wireless connectivity provides the latest weather information,
software updates, and energy management features.
Lumen’s intelligent power management system optimizes your energy production with your energy
consumption. An interactive touchscreen offers an enhanced user experience and real time
information. The Automatic transfer switch included in Lumen seamlessly merges solar and electric
utility power when grid power is available and ensures no interruption during a power outage.
How It Works
Lumen harnesses the Sun’s energy to provide power for your home. If you are generating more solar
energy than you are consuming, the power is stored in the battery for use at another time during the
day. If you consume more than the Sun is providing, Lumen draws the additional required power from
your local utility. In the event of a power outage, the power detection system automatically switches
to Lumen’s Li-NMC batteries. With Lumen, there is Energy Always.
Smart Features
Your Lumen includes inverSOL’s unique power optimization system. The Lumen smart features
minimize wasted solar power and reduce energy bills by maximizing the use of the battery while at
the same time ensuring capacity will be available when the sunshine is reduced or inclement weather

Voltage inside the Storage System
The solar storage system contains live electrical parts, which poses a risk of electrical shock.
Therefore, do not open the storage system.
Handling the Battery Modules
The battery modules installed in the solar storage system are protected by multiple protective
devices and can only be operated safely when installed in the unit. Despite their careful design, the
battery cells inside the battery modules may corrode or experience thermal runaway in the event of
mechanical damage, heat or a fault.
This can have the following effects:
1. High heat generation on the surface of the battery cells.
2. This may ignite and cause an explosive ame.
3. The smoke from burning battery modules can irritate the skin, eyes and throat.
Therefore, proceed as follows:
1. Do not open the battery modules.
2. Do not mechanically damage the battery modules (pierce, deform, strip down, etc.)
3. Do not modify the battery modules.
4. Do not allow the battery modules to come into contact with water (except when extinguishing a re
in the storage system).
5. Do not heat the battery modules. Operate them only within the permissible temperature range.
6. Keep the battery modules well away from sources of ignition.
7. Do not short-circuit the battery modules.
8. Do not continue to use the battery modules after a short circuit.
9. Do not deep discharge the battery modules.
Safety

Conduct in Case of a Fire
Fire may occur with electrical equipment despite its careful design. Additionally, a re in the vicinity
of the equipment can cause the storage system to catch re, releasing the contents of the battery
modules.
In the event of a re in the vicinity of the product or in the storage system itself, proceed as follows:
1. Only reghters with appropriate protective equipment (safety gloves, safety clothing, face guard,
breathing protection) should enter the room where the burning storage system is located.
2. There is a danger of electrocution when extinguishing re while the storage system is switched on.
1. Switch off the storage system to electrically isolate it (see Switching the storage system off
to electrically isolate it).
2. Switch off the main circuit protection device in the building.
3. If the storage system and/or mains fuses cannot be safely switched off:
1. Observe the minimum distances specied for the extinguishing agent used.
4. The storage system works with an output voltage of 240 V (AC) and is therefore considered a low-
voltage system.
1. A storage system re can be extinguished using conventional extinguishing agents.
2. Water is recommended as an extinguishing agent in order to cool the battery modules and
prevent thermal runaway in battery modules which are still intact.
Information on the battery modules:
• The battery modules have a nominal voltage of 24 V (DC) and therefore fall into the range of
protected extra-low voltage (under 60 V DC).
• The battery modules in the Lumen is LiNMC

Product Description
The Lumen unit is designed to provide you with years of uninterrupted power. It produces up to 4800
watts of split phase 240 VAC and/or 120 VAC. It also reduces your utility bills by substituting solar
power for utility power. The proprietary algorithm running in the Lumen’s controller optimizes the use
of solar. All of the up to 4800 watts of solar energy produced is either consumed when produced or
stored in the battery for later use. Therefore, there is no need for net metering. In addition, the energy
storage system provides backup power when solar or utility power is not available. Figures 1 and 2
depict how the energy ows with Lumen with the grid power on and off.

Figure 2. Lumen Operation When Current Flows without Grid Power
The intelligence in the Lumen provides uninterrupted power to your home or small business. The
smart transfer switch automatically combines the available energy from solar, utility, and battery to
ensure you always have power. The unit comes preprogrammed to rst consume all available solar
energy that is generated during the day. If you consume more power than is produced by solar, the
system will draw the additional power required from the electric utility. If solar and utility power is not
available, the system will operate from the battery. Lumen will reduce your utility bills by the amount
of solar power that is generated.
At the heart of Lumen’s energy storage system is an expandable 5000 Wh LiNMC battery. The battery
is designed for more than 10 years life under normal operating conditions. The intelligent charging
system is programmed to fully charge the battery in under 4 hours. The energy storage system is
also expandable up to 20,000 Wh. Table 1 shows the available energy storage options along with the
charge time and run times for each.
The Lumen includes a powerful embedded computer with a touch screen user interface. You can
congure the system and monitor the performance through this interface. In addition, the user
