3.7 - External Components
This section provides additional details about the key external components that connect to
the SolarCity H6 inverter.
3.7.1 - PV Array
The SolarCity H6 inverter supports a number of PV string combinations for optimal
performance, which include:
• Wide full power MPP voltage range of 200V to 480V.
• Ability to begin functioning at voltage ranges of 120V to 550V.
• Ability to operate to as low as 85V.
Each MPPT channel can accommodate up to two (2) strings with a maximum continuous
current input of 19A and a short circuit current of 26A. Guaranteed 6kW AC output power
from PV energy requires connecting PV strings to both MPPT channels because each channel
is only rated for 4.5kW (up to 75% imbalance), with the rest on the other MPPT channel. The
total power of the PV array can range up to 150% (9kW) of the SolarCity H6 inverter maximum
AC rating of 6kW.
Note: Inverter output power is limited by both input current and voltages
that are above or below the full MPP range.
Note: System wiring voltage losses should not exceed one (1) to two (2)
percent for optimal system efficiency and performance.
