*1 The rated power of modules under Standard Test Conditions (STC) should not exceed the optimizers’ rated DC input power. Module power may be up to 5% higher than the optimizer’s rated power.
*2 A faulty optimizer will be bypassed so other optimizers and inverters are not affected by the failure.
*3 When the optimizer output is open or the inverter connected to the optimizer is turned off, the optimizer’s default output voltage is 1 V DC.
*4 For the short input cable version (input cable 0.1 m (+/-), output cable 0.1 m (+), 5.1 m (-)), ensure PV module cables are long enough to connect to the optimizers. A long input cable version is available on request.
*5 When the optimizer’s operating temperature reaches 70°C to 85°C, the optimizer may shut down due to overheat protection and trigger an alarm. After the temperature drops to 70°C or below, the optimizer will automatically resume operation without risk of damage.
