 Wiring the KP100L to the Solar Modules
• First make sure the maximum open circuit voltage Voc of each PV string is below 850 VDC under any
condition.
• Always connect solar module positive (+) terminal to KP100L DC positive (+) terminal, and the solar module
negative (-) terminal to KP100L DC negative (-) terminal.
• KP100L has 3 MPPT. Usually solar modules are connected to 3 DC terminals as illustrated in figure below.
Mount the enclosed MC caps onto MC connector that is not used. Each set of DC terminals takes a maximum
DC input of 13A. 3 pairs of DC terminals can take a combined input of up to 33A. Maximum PV input power for
each tracking is 5,500W.
• One PV-panel can be connected to 3 DC input as illustrated in figure below. To fully optimize the PV output
set-up, use the following configuration guidelines:
(a) For PV output

13A, use a single pair of DC terminals.
(b) For 13A

PV output

26A, use 2 sets of DC terminals.
(c) For 26A

PV output

33A, use 3 sets of DC terminals.
Be especially careful about electric shocks during the daytime, because that is when the solar modules are in the
power generating mode. Confirm the polarity of the cable from the solar modules to ensure correct connection
and make sure that there is no slackness of MC connectors.
