case, the device will automatically limit its power as long as this abnormal situation persists. Do
not expose REhub to any dripping liquids.

Wiring
Wiring must be done by a professional qualified for such installations. Take extra care
while connecting High voltage systems, Battery terminals.
Take care to not connect the panels to the battery input or the connection of the batteries
to the PV input.
TAKE CARE not to connect the AC line to any of the DC (PV or Battery) connections.
REhub is intended to be connected exclusively to Solar Photovoltaic source. It is suitable
for charging any type of lead-acid batteries.
REhub is electronically protected against overloads, PV short-circuits, overheating, polarity reversal
of the battery, polarity reversal of the PV.

Components of the Cable Compartment
Access the cable compartment after removing the L Plate.
Cable entry is through the slot in the L Plate. Close the L Plate after the terminals are sufficiently
tightened and all the connections are checked for correctness. Refer wiring drawing in the last

Solar PV connections
REhub accepts input voltages between 0V to 90V. It can start charging the batteries when the
input voltage is above the battery voltage. Keep the connection ready. Close the connections when
you are ready to POWER Up.
5.3
Serial connection of Solar PV string
REhub can operate at a much higher PV voltage compared to the Battery system Voltage. It is
therefore not necessary to match the PV panel voltage to the Battery Voltage. However the name
