Wiring the KP100G to the Solar Modules
z
First make sure the maximum open circuit voltage Voc of each PV string is below 800VDC under any condition.
z
Always connect PV-Panel positive (+) terminal to PV-Inverter DC positive (+) terminal, and the PV-Panel negative (-) terminal to PV-Inverter DC
negative (-) terminal.
z
KP100G has 3 MPPT trackers. Usually PV-Panels are connected to 3 DC terminals as illustrated in Fig, 5-35(a).
Each set of PV-Inverter DC terminals takes a maximum DC input of 13A. As a result, 3 pairs of PV-Inverter DC terminals can take a combined
input of up to 39A.
Maximum PV input power for each tracker is 5,500W.
z
One PV-panel can be connected to 3 DC input as illustrated in Fig, 5-35(b) .
To fully optimize the PV output set-up, use the following configuration guidelines:
(a) For PV output less than 13A, use a single pair of PV-Inverter DC terminals.
(b) For PV output between 13A and 26A, use two sets of inverter DC terminals.
(C) For PV output between 26A and 39A, use three sets of inverter DC terminals.
(a) 3 Panel Strings (under 39A) (b)1 Panel String (between 13A and 39A)

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 PV module to ensure correct connection and make sure that there is no slackness of MC connectors.
