When the DC input is not fully configured, the DC input terminals must meet the following
requirements:
• Evenly distribute DC input power cables to the four MPPTs. MPPT 1 and MPPT 4 are
preferred.
• Maximize the number of connected MPPTs.
PV1, PV2, PV3, PV5, PV7, PV8

•
Use the positive and negative Amphenol Helios H4 metal terminals and DC connectors
supplied with the solar inverter. Using incompatible positive and negative metal terminals
and DC connectors may result in serious consequences. The caused device damage is not
covered under any warranty.
•
You are advised to use the H4TC0003 (Amphenol) crimping tool and do not use it with the
positioning block. Otherwise, the metal terminals may be damaged. The H4TW0001
(Amphenol) open-end wrench is recommended.
•
Ensure that the PV module output is well insulated to ground.
•
The DC input voltage of the SUN2000 shall not exceed 1100 V DC under any circumstance.
