5.7.2 - Fuses

The SolarCity H6 inverter accepts a maximum battery pack fuse rating of 25A.

SolarCity recommends the 25A LittleFuse KLKD025 or Bussman KLM-25 fuses.

5.7.3 - Communications

Updates to the battery pack firmware are sent via the ZigBee communication interface. The

inverter receives the firmware and passes it on to the battery pack via the CAN interface.

During the firmware upgrade process, the system may either continue to operate or may go

into boot mode until the upgrade is completed and then restart automatically. SolarCity

normally upgrades firmware at night when grid power is present. Any loss of grid power

during the upgrade reverts to the previous version and restarts the system. Failure to

upgrade firmware automatically schedules another attempt.

Note: Actual wiring colors may vary from those shown on the wiring box

label and/or this Guide.

CAUTION: LARGER FUSES WILL VOID THE WARRANTY.

CAUTION: FUSES THAT ARE TOO FAST MAY OPEN TOO EARLY AND

INTERRUPT NORMAL OPERATION. FUSES THAT ARE TOO SLOW MAY OPEN

TOO LATE, THEREBY NOT PROVIDING THE REQUIRED LEVEL OF

PROTECTION.

Note: These values are subject to change. Please refer to the SolarCity H6

Inverter Datasheet for updated values.
