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 yourutility bills, provides backup power, and reduces your carbon footprint.
LFP (lithium-ion phosphate battery) cells used in Lumen+ are assembled in 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.
The Lumen+ 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 fromyour local utility. In the event of a power outage, the power detection system
automatically switches to Lumen+’s LFP batteries. With Lumen+, there is Energy Always.

Safety
Voltage inside the Storage System
The solar storage system contains live electrical parts, w hich 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, thebattery cells inside the battery modules may corrode or experience
thermal runaway in the event ofmechanical 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 flame.
3. Smoke from burning battery modules can irritate the skin, eyes, and throat. Therefore,
please note the following safety precautions:
•Do not open, modify, deform, or otherwise tamper with the battery modules.
•Do not allow the battery modules to come into contact with water, except when
extinguishing a fire.
•Do not heat the battery modules or allow to operate outside the permissible
temperature range.
•Keep the battery modules well away from sources of ignition.
•Do not short-circuit the battery modules. Discontinue use after a short circuit.
•Do not deep discharge the battery modules.

Safety
Conduct in Case of Fire
Fire may occur with electrical equipment despite its careful design. Additionally, a fire in the vicinity
of the equipment can cause the storage system to catch fire, releasing the contents of the battery
modules.
In the event of a fire in the vicinity of the product or in the storage system itself, proceed as
follows:
1. Only firefighters 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 fire while the storage
system is switched on.
•Switch off the storage system to electrically isolate it (see Operation).
•Switch off the main circuit protection device in the building.
3. If the storage system and/or mains fuses cannot be safely switched off:
•Observe the minimum distances specified 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.
•A storage system fire can be extinguished using conventional
extinguishing agents.
•Water is recommended as an extinguishing agent to cool the
battery modules and prevent thermal runaway in battery
modules which are still intact.
Information on the battery modules:
•Battery modules have a nominal voltage of 48 V (DC) and therefore fall into
the range of protected extra-low voltage (under 60 V DC).
•Battery modules in the Lumen+ are LFP (Lithium-Ion Phosphate).

Product Description
The Lumen+ unit is designed to provide you with years of uninterrupted power. It produces up to
6000 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+ controller optimizes
the use of solar. All the solar energy produced (up to 6000W) is either consumed when produced
or stored in the battery for later use. 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 flows with
Lumen+ when the grid power is on and off.

www.inversolpr.com User Manual Lumen+ 9
The intelligence in the Lumen+ provides uninterrupted power to your home or small business. The
smart transfer switch automatically combines the energy available from solar, utility, and battery to
ensure you always have power. The unit comes pre-programmed to first 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.

Operation
The intelligent controller in your Lumen+ makes it easy to operate. To turn the unit on, open the
unit’s door and turn on the Load / Battery / Grid / and Remote switches. The display will power
up, run initialization self-tests, and pre-program default settings. This takes about 20 seconds. To
turn the system off, turn the Load / Battery / Grid / and Remote switches to the off position.
Power Outage: In the event of grid outage, the unit’s operation depends on available solar energy
- Photovoltaic (PV) - and battery power to deliver power to the home (load).
•When the load is higher than P V output, then PV and Battery will power the load. If the
load is less than the PV capacity, then PV will charge the battery and power the load.
•When PV is unavailable (night), the battery powers the load. If PV becomes available
before battery shutdown, then PV charges the battery and powers the load.
•When PV is unav ailable for an extended time, the battery will eventually shut down
and stop powering the load. When the Grid or PV becomes available again, the Lumen+
acts as an off-grid unit, powering the load but not charging the battery. Turn off the Remote
switch for 5 seconds and turn it back ON to start charging the battery.
Note: If the battery goes down and then PV returns, the Lumen+ will NOT power the load and will
NOT charge the battery. Please turn off the Remote switch for 5 seconds and turn it back ON to start
charging the battery. Please monitor the load, battery charge, and solar energy generation during
an outage to avoid battery depletion.
Storage: Turn the Load / Battery / Grid / and Remote switches to the off position when the unit is
stored to disconnect the battery and maximize storage life.
