1Introduction and General
1.1 Foreword
Thank you for choosing Power-Blox. We are sure that you will enjoy our innovative energy cube. We have
spent several years developing the product to make it as easy as possible to use and to give you access to
sustainable electricity even in places where there is no power outlet.
With Power-Blox you can use solar energy in a simple, flexible and scalable way. No matter whether you
use a Power-Blox as a single device, combined as a tower or even as a Power Wall of up to nine or more
devices. Set no limits to your imagination and your energy projects. The swarming algorithm we have
developed, on which the Power-Blox is based, makes off-grid and mini-grid energy projects easier than
ever before.
Actually no manual is needed for the "normal" use of the Power-Blox. Set it up, plug in the solar module,
switch it on, done. Nevertheless, the Power-Blox is an energy product that produces dangerous
alternating current with a voltage of 230 V. In addition, unfavourable handling can considerably reduce its
service life. To enable you to operate the Power-Blox safely for several years, we would ask you to study
these instructions carefully. You can also visit our YouTube channel and watch short films about the
essential steps.
Whatever you plan to do with your Power-Blox: We wish you many sunny days and a high-energy time.
Best wishes,
Your
CTO & Co-Founder
Frick, August 23, 2019

2.3 Storage and transport
If the PBX-200 is stored or not used for a long time, make sure that the PBX-200 is switched off via the
main switch.
The PBX-200 must be stored fully charged in clean, dry, cool and frost-free rooms. Too high storage
temperatures lead to increased self-discharge and premature aging. To prevent a deep discharge of the
batteries and to achieve the longest possible battery life, the PBX-200 must be recharged regularly:
- PBX-200 Pb: fully recharge every 3-4 months
- PBX-200 Li: recharge to only about 50% every 6-7 months
Alternatively, a solar module can also be connected to the PBX-200. When the solar module surface is
exposed to sunlight, the battery of the PBX-200 charges even if the PBX-200 is switched off via the main
switch.
To prevent damage to the product, a suitable transport device and the original transport packaging must
be used when shipping or transporting the PBX-200. During transport, the PBX-200 must be properly
secured to prevent damage and potentially dangerous malfunctions to the PBX-200 and the battery.
When transporting the PBX-200 by car, truck, ship, and plane, the respective applicable standards and
regulations must be observed.

3Overview of the PBX-200
The two integrated AC sockets (1) on the top of the lid supply 230 V AC (alternating current). It is possible
to connect commercially available devices directly via these sockets. The power of the PBX-200 should not
be exceeded (for a single PBX-200: 200 W, short-term 400 W). Only one consumer device per socket is
permitted.
Figure 1: PBX-200 front panel
Below the LED display (2) and next to the main switch (3), the PBX-200 provides two 5 V USB ports with up
to 2.1 A (5). The additional 12 V car socket (4) to the left of the main switch supplies up to 3 A. In total,
consumer devices with a total output of 36 W can be connected to (4) and (5).

Installation and Operating Instructions PBX-200 Pb ; Li ; Li/LE Page 9
Figure 2: Front connections and main switch
The extensive range of electrical connections is located on the back of the PBX-200. A solar module can be
connected directly to the PBX-200 using an adapter cable (solar cable) at the solar input socket (8). If the
solar module does not supply enough energy, for example on short winter days, the PBX-200 can also be
connected and charged directly to a 230 V socket via the cold appliance socket (7). Two resettable
miniature circuit breakers (13) protect the PBX-200 against overload. At the transfer sockets (6), further
PBX-200s can be connected to a network via the transfer cable (9). A resettable miniature circuit breaker
(12) protects the transfer lines / the swarm against overload. The transfer cable can be stowed in the
cable ducts (10, 11). To prevent the PBX-200 from changing hands unintentionally, it can be chained via
the anti-theft protection (15). There are additional clamp connections (16-19) under the cover (14).
Figure 3: PBX-200 rear panel
The clamp connections are an alternative way of connecting the PBX-200 to a solar module (16) or an
external 230 V power source (18). Several solar modules can be connected to the PBX-200 in parallel. The

Installation and Operating Instructions PBX-200 Pb ; Li ; Li/LE Page 10
total possible current must not exceed 8 A, otherwise the solar modules must be protected by a DC fuse.
Access to the clamping area is only permitted for qualified electricians. The installation flap (14) covers
and protects the terminal connections. For safety reasons, the installation flap must be closed and
screwed on both sides during operation.

6Installation and commissioning
Important note
Only the installation of the PBX-200 is described below. When installing external components
(solar module, consumer device, cable) the relevant instructions must be followed.
6.1 General
Risk of electric shock
The electronics housing of the PBX-200 must not be opened.
The installation flap (14, chapter 3) must be closed and screwed down during operation.
Always carry out the following measures before working on the PBX-200:
1. Switch off the PBX-200 via the main switch.
2. Switch off all consumer devices and disconnect them from the PBX-200.
3. Disconnect the solar cable with solar module from the PBX-200.
4. Disconnect transfer cable connections (if any).
5. Open external fuses before the terminal inputs Generator / Mains and Transfer and
secure against reconnection.
6. Check that the sockets on the PBX-200 are voltage-free.
Danger
-The PBX-200 may only be connected to other PBX-200s via the transfer cable or the transfer
terminals when it is switched off.
-Adhere to technical data, in particular the connection values of consumer devices and solar
modules.
-When selecting the solar module, make sure that its open-circuit voltage at temperatures
below 25 °C is higher than that specified on the type plate.
-Maximum open circuit voltage of the solar generator must not exceed 45 V.
-Secure cables that are clamped to the PBX-200 via the terminal strips with a strain relief.
-Connect only one conductor to each terminal.
-Lay the cable so that:
—connections cannot become loose accidentally.
—persons cannot step on or trip over it.
—fire protection equipment is not affected.
