System Conguration
Once a SimplBox is attached to a solar panel, it uses its mesh networked core to wake up and au-
tomatically connect to the Simpl’s web-hosted database, SimplWeb. Simpl’s partners have access
to SimplWeb via a carefully-designed API and can extract relevant data or develop a custom ap-
plication for their customers.

SimplBox Specications
4.0 Installation
SimplBox is an energy storage system that intercepts the connection between a micro-inverter
or power optimizer and a solar panel. Due to this fact, the system is easy to install and very
similar to common micro-inverter installations.
The steps are as follows:
1. Prepare for the Installation
a. Site Preparation
b. Tools and Hardware Required
2. Unpacking and Inspection
3. SimplBox Installation
a. SimplBox Mounting
b. SimplBox Grounding
4.1 Prepare for the Installation
Before the installation process of your SimplBox system begins, take the time to read through the
entire Installation section of this manual. The more thoroughly you prepare and plan in the
beginning, the smoother the installation process will be. Familiarize yourself with the installation
process and help reduce or eliminate any time-consuming or costly mistakes.

Installation and Setup Guide
INFORMATION: Installations should be performed by qualied personnel, such as a
licensed or certied electrician. It is the installer’s responsibility to determine which
building, electrical, and safety codes apply and to ensure that all applicable
installation requirements are met or followed.
INFORMATION: Les installations doivent être effectuées par du personnel qualié, tel
qu’un électricien agréé ou certié. Il est de la responsabilité de l’installateur de dé-
terminer les codes du bâtiment, de l’électricité et de la sécurité s’appliquent et pour
s’assurer que tous les les exigences d’installation sont respectées ou respectées.
CAUTION: Review the “Important Safety Information” prior to any installation proce-
dures.
ATTENTION: Consultez les «Informations de sécurité importantes» avant toute procé-
dure d’installation.
CAUTION: The simplied diagrams shown in this manual are provided to assist
in planning and designing an installation. They are not intended to override
or restrict any national or local building or electrical codes. These diagrams should
not be the determining factor as to whether or not the installation is code
compliant. Code compliance is the responsibility of the electrician and on-site
inspector.
ATTENTION: Les schémas simpliés montrés dans ce manuel sont fournis pour aider
dans la planication et la conception d’une installation. Ils ne sont pas destinés à
remplacer ou restreindre les codes du bâtiment ou électriques nationaux ou lo-
caux. Ces diagrammes devraient ne pas être le facteur déterminant pour savoir si
l’installation est ou non du code conforme. La conformité au code est la respons-
abilité de l’électricien et sur place inspecteur.
Page 17
4.2 Site Preparation
SimplBox is designed to be installed under a solar panel. Before installing SimplBox, locate the cen-
ter of each solar panel on the solar racking rail. The width of a SimplBox and microinverter comfort-
ably positioned side by side should be centered within the panel footprint. Do not position SimplBox
between solar panels as that may block the location of the solar panel mid-clamps or end-clamps.

Installation and Setup Guide
4.4 Unpacking and Inspection
Each SimplBox is completely assembled and tested at the factory prior to shipping. Various events
may happen during transport that could damage the system. Inspect the system and packaging
thoroughly for any damage to the system. If there is damage to the SimplBox housing, connectors,
or visible corrosion, leaking, etc. do not install the unit and contact Simpl Global for instructions.
4.3 Tools and Hardware Required
In addition to solar panels, solar racking, microinverters and its associated hardware, you will
need to provide the following:
●Electrical multi-meter / voltage tester
●Sockets, wrenches for mounting hardware
● Torque wrench
●MC4 Removal tool
●(2) Microinverter mounting bolts per SimplBox
Page 18

Installation and Setup Guide
Page 19
INFORMATION: The two MC4 connectors on SimplBox that connect to a solar panel
will be connected together when the unit arrives. DO NOT unconnect these connec-
tors from each other until they are ready to be connected to a solar panel. Uncon-
necting these connectors prior to being ready to connect them to a solar panel may
damage the unit and void warranty.
MC4 Solar Panel Connectors
Solar connectors are shroted together in during shipping.
Keep shorted until you are ready to connect to the solar panel.
MC4 Microinverter/Power Optimizer / Inverter
Connectors
4.5 SimplBox Grounding
SimplBox does not require any type of external grounding equipment such as bare copper wire
or bonding washers. All live parts inside of SimplBox are protected by the units plastic enclosure or
double insulated parts. All other equipment such as microinverters, solar modules, solar rails, etc.
MUST be grounded as specied by the manufacturer.

Installation and Setup Guide
1. Connect the inverter connec-
tors to the inverter, rst.
2. Then connector the solar panel
to the solar cables
4.6 SimplBox Installation
SimplBox should be mounted on the solar racking system after the rails have been secured to the
roof but before the solar panels are mounted to the rail. The installation should follow the steps be-
low.
1. Secure the solar rails to the roof.
2. Mark out the locations where SimplBox and the microinverter or power optimizer will be located
under each solar panel. They should be located near the center of each solar panel, in a posi-
tion that will not interfere with the solar panel mounting hardware, such as mid-clamps and end-
clamps.
3. Mount SimplBox and the microinverter or power optimizer to the solar rail. See section 4.6.
4. Connect SimplBox to the microinverter or power optimizer via the supplied MC4 connectors.
5. Position the solar panel and connect it to SimplBox via the supplied MC4 connectors. The con-
nectors on SimplBox that connect to the solar panel will arrive connected together. DO NOT uncon-
nect them from each other until they are ready to be connected to the solar panel. Unconnecting
these connectors from each other prematurely may damage the unit and void warranty.
