� Before connecting PV panels to t he DC t erminals, please make sure t he polarit y is
correct . Incorrect polarit y connection could damage t he inverter.
�
Check short-circuit current of t he PV string. The total short-circuit current of t he PV
string should be less than the inverter's maximum DC current.
�
Connect the positive and negat ive terminals from t he PV panel to positive ( +) terminals
and negative( -) terminals on the PV-Invert er. Each DC terminal on Inverter can
withst and 11A.
♦
For inst ance, if t he positive pole of a st ring is connect ed at MPP t racker A and the
string's negat ive po le at MPP tracker B, this is called a mixed connect ion, the
inverter no longer fulfils the requirement s of t he EMC Directive.
♦ Only connect strings at one input zone and never mix the input zones A and B.
♦ High volt ages exist w hen the PV panel is exposed to t he sun. To reduce risk of
elect ric shock, avoid touching live components and treat connect ion terminals
carefully.

5.6.6 Connect To The Battery
� Before connect ing to t he batt ery, you must inst all a separate DC breaker (not less than
120A) betw een t he inverter and batt ery. That will ensure the inverter can be securely
disconnected during maintenance.
� DANGER
Reversed polarity will damage the inverter!!!
�
It is very important for system safet y and efficient operation t o use appropriate cable
for batt ery connect ion. To reduce risk of injury, you much use t he proper
recommended cable size, refer t o the following;

� The batt ery must be installed in accordance wit h the manufacturer' s instructions.
� The MAX charge/ discharge current of t he inverter is 50A.
�
The inverter' s batt ery rat ed volt age is 48V. The bat tery series connection voltage must
not exceed 48V or it w ill damage t he invert er and void any warranty.
Follow the below steps to implement the battery connection:
(1) Check t he bat tery nominal voltage meets the inverter spec.
(2) Disconnect the breaker bet ween inverter and battery.
(3) Check out the polarity of t he bat tery and t he inverter.
(4) Terminate batt ery DC cables by means of t he lugs provided.
(5) Screw the DC cable t o the inverter's bat tery input terminal.
(6) The correct batt ery technology m ust be selected upon commission, so t hat it can
be cont rolled via the BMS

NOTE
w e recommend using the Solarshop appoint ed lit hium battery, because the bat tery

Inverter.
� � DANGER
Danger to life due to voltages!
Before you
inst all the BAT.NTC, you must t urn off t he invert er, check all t he separate
breake rs are off, and the inverter's LED is off. Then you can safely install t he BAT.NTC
terminal t o the invert er.
