IMPORTANT INFORMATION AND SAFETY INSTRUCTIONS

1. IMPORTANT INFORMATION AND SAFETY INSTRUCTIONS
Installers should be qualified electricians or technicians
The installation information in the manual is for information purposes only.
Read the instructions carefully before installing and operating the PV Booster.
Retain the load within the rating to prevent faults.
Sketches are intended for illustrative purposes only and are not intended to provide an
electrical design.
High voltages are present –With this device even a single PV panel can produce a lethal 800
Volt DC.
This unit is not a consumer product and should only be handled by qualified electricians.
Always ground the device to avoid electric shock. A grounding wire connection is provided.
The inherent current limiting associated with a solar panel is part of the Solar Voltage Booster
design.
Running the unit from a battery or bench supply will cause it to fail, even when lightly loaded.
Never series the output of individual PV Boosters, as this will increase the output voltage
above the isolation specification of the unit and may cause electric shock
WARNING
HIGH VOLTAGES PRESENT
Voltages capable of causing severe injury or death by electrical shock are present in this
unit.
WARNING
Maximum Panel Input Voltage: 10V to 50V
Panel Power: Max 360W

2. INTRODUCTION
General Description2.1
The Solar Voltage Booster steps up the voltage level of a photovoltaic (PV) panel to the level
required for the Microcare pump controller. This allows any number of voltage boosted solar panels
to be paralleled, removing the concept of „array voltage‟ when designing a solar pump system.
Key Features2.2
Solar Voltage Boosters are installed on a per-panel basis.
Each panel in the array requires an accompanying Booster. This limits the usefulness of the
Solar Voltage Booster to 375W, 550W, 750W and possibly 1.1kW installations. After that the
costs associated with the addition of Boosters are not currently economical.
The Solar Voltage Booster is specifically designed for standard 300W (250W to 350W) with a
Maximum Power voltage (VMP) of 35V to 40V.
Only PV Panels with an open circuit voltage (VOC) lower than 50V are supported.
At higher voltage levels the safety circuits will protect the Booster by short-circuiting the panel
input.
The Solar Voltage Booster is designed for mounting behind an accompanying PV panel.
Long feed-wires are not supported (longer than 4 meters) and may cause voltage spikes to
activate the protection circuits.
Solar Voltage Booster outputs should be paralleled.
To this end each Booster is fitted with a high voltage input.
The high voltage output of one Booster feeds into the high voltage input of the next Booster in
the string.
Please Note : Max Panel Input Voltage Voc : 10V to 50V
Panel Power: Max 360W
