1. INTRODUCTION
The PB 1000 is a unique storage device (a complete off-grid solution) that contains all the constituent
parts of a solar power system within its weatherproof casing. The design is so simple that the user could
quickly set up a simple solar power system to provide AC for devices with power up to 1000 W.
In the casing, there is a charge controller, a storage bank of 4 x 443Wh lithium-ion batteries, a DC-to-AC
inverter, and a logic program that manages the whole system. All that is visible on the outside is the cable
that takes the DC power from the solar panels and AC power outlet.
It can run TVs, computers, lights, fans, and any other utility within its operating limits. The unit can power
a mixed load with power up to 1000W and battery storage of 2000Wh. In addition to that, it is equipped
with temperature control and overload protection, while a PCM card protects each battery card.
The PB 1000 can operate at any time of the day and be set to ‘automatic’ mode, in which it operates only
at night or when power is required. It can either operate 24hrs or be set in the UPS mode, where it
operates only at night or where power cuts out.
PB 1000 has four terminals (left to right):

2 x Solar In;

1 x 24V DC Out;

1 x AC Out.
Also visible on the bottom, there is an air-intake and an outlet fan-grill.
For the power bank to function, it must have both solar panels plugged in.

The brackets are padded in the inside to prevent any damage caused by the metal to the battery sleeve.
There are two Phillips screws per bracket, and the holes in the mounting board are already threaded.
Each battery pack comes with two sets of leads.
In the installation process, we are only concerned with the pair that is black and red.
Place the batteries sideways into the container with the leads heading towards the PCB, with the black
leads secured out of the way.
The bracket should be placed over the batteries and secured in place by the two screws. The holes in
the metal mounting board are clearly visible.
5.2. Mounting the System
1. Install the solar panels using the L brackets provided and connect the cables to the PB 1000.
2. Mount the PB 1000 onto a non-flammable wall.
Solar panels can be installed either on the roof or the ground. When selecting the location to install solar
panels, several conditions must be taken into account. We will address some technical considerations
and details that you should pay attention to before choosing where to install your solar panels.

Orientation and Inclination:
If the place is located in the Northern hemisphere of the Earth, then the solar panels should face the
South. On the other hand, areas located in the Southern Hemisphere of the planet must face North for
maximum energy performance.
Shadings:
PV systems cannot work efficiently with an object that continually causes shades in the PV array;
therefore, you must consider the presence of nearby trees, chimneys, antennas, or houses that could
cause shade on your solar panels.
6. WIRING
When assembling a solar power system using the PB 300 XL, it is necessary to attach cables 3-way (AC)
connectors and for the DC MC4 connectors are used. The following is an assembly instruction for both
AC/DC connectors.
6.1. The AC three-way connector:
a) Yellow/green – Earth
b) Blue – Neutral
c) Brown – Phase
The letters E, N, and L are engraved
on the green connector.


Night Only – System OFF during the day and ON during the night.

ON – System ON and ready to be used all the time.
LED Indicators:

Inverter ON – System OK and powered ON.

Night Only – System OFF during the day and ON during the night.

Full Charge – Batteries are fully charged.

Charging – Batteries are charging.
Buzzer Indicators:

“Beep…beep…” – System overload indication.

“Beep beep…beep beep…” – System low voltage indication.

“Beep beep beep… beep beep beep” – System high voltage indication.

“Beep beep beep beep…beep beep beep beep” – System high temperature indication.

“Beep beep beep beep beep…beep beep beep beep beep” – System short-circuit indication.
Once the PB 1000 has been fixed into a suitable location, solar panels wired, batteries connected, and
AC wired to a fuse board or power block, it is time to turn on the device.
7.1. Switching On
The two switches are positioned at the bottom of the
circuit board.
a) Left side switch (On Off) powers on the device
b) Right side switch ‘II’ selected sets night only and
when positioned in ‘I’ sets 24 hours on.
The user must turn on the PB 1000 and select
whether it should operate for 12 hours or 24 hours.
Then, the box cover should be closed and secured.
The device will not require any further adjustment.

8. SAFETY INSTRUCTIONS
The PB 1000 is an off-grid system, which means it cannot be connected to the supply grid.
The following instructions should, therefore, be read before any installation takes place:
1. DO NOT attach any part of the PB 1000 or any system that it is part of, to mains grid supply.
2. When installing any system using the PB 1000, ensure a certified electrical engineer is present to
check the system is assembled correctly and safely.
3. Although the PB 1000 is built into a weatherproof box it is advisable to place a rain/sun shelter or
awning over the top.
4. When installing the cabling between solar panels and the PB 1000, ensure the wiring is not connected
to the panels until the circuit is assembled and complete.
5. The PB 1000 should not be positioned near any flammable material or in any location which may
accumulate flammable fumes or gases.
6. Make sure the vent holes and fan grill are not obstructed to prevent overheating.
7. Only used approved cabling when making a solar power system.
8. PB 1000 is designed to use 4 x 443Wh lithium-ion battery packs. No other source of power should be
used.
9. DO NOT immerse the PB 1000 in water; it is not waterproof.
9. TROUBLESHOOTING
Once the Power Bank 1000 is set up, there is very little to do. However, if there is no power coming out
of the PB 1000 (after 24hrs), please check the following.

The switches are on and set to night only or 24 hrs.

The wiring from the batteries is firmly connected to the main circuit board.

The cabling coming from the solar panels is properly connected to the PB 1000 via one of the two
terminals.

The solar panels are exposed to the sun for at least 6 hours a day.

There is no obstruction to the solar panels blocking the sun’s rays.

OVERLOADING - If too many appliances are connected to the PB 1000, it will shut down.

In that case, unplug those appliances and wait 5 minutes while the system resets itself. Then reattach
a reduced number of appliances (reduce the load).
