① Rating for 8000 cycles at 0.25C with EOL at 70% capacity (for ESS-TRENE).
Notes for X3-TRENE-125K (Inverter):
① The maximum input voltage is the upper limit of DC voltage. Any higher DC input voltage will likely damage the inverter.
② Input voltage exceeding the MPPT voltage range may trigger inverter protection.
③ Isc (short-circuit current) for a single PV input string is 35 A.
