Danger:
•
Before connecting the PV generator, ensure the DC-switch is switched off and that it cannot be reactivated.
•
Do not disconnect the DC connectors under load.
There are two MPP trackers for Astronergy CHPI KTL-M2, you can connect two independent MPP channels.
•
Under any condition! Make sure the maximum open circuit voltage (Voc) of each PV string is less than 600Vdc.
•
Do not connect strings with an open circuit voltage greater than the Max. input voltage of the inverter. If the strings
voltage exceeds the Max. input voltage of the inverter, it can be destroyed due to overvoltage. All warranty claims
become void.
•
Check the design of the PV plant. The Max. open circuit voltage, which can occur at solar panels temperature of -10 °C,
must not exceed the Max. input voltage of the inverter.
•
Open the independent DC circuit breaker as well as the DC switch on the Astronergy CHPI KTL-M2 inverter.
•
Before connecting PV panels to DC terminals, please make sure the polarity is correct. Incorrect polarity connection could
permanently damage the unit. Check short-circuit current of the PV string.
•
Connect the positive and negative terminals from the PV panel to positive (+) terminals and negative (-) terminals on the
PV-Inverter. Each MPP tracker’s max. input current as follow:
15A for CHPI 5KTL-M2
15A for CHPI 4.2KTL-M2
10A for CHPI 3.6KTL-M2
•
High voltages exist when the PV panel is exposed to the sun. To reduce risk ofelectric shock, avoid touching live
components and treat connection terminals carefully
