Notes:
• ¹ Rated Input DC Power must not be exceeded by the PV module's STC power; modules with up to +5% power tolerance are allowed.
• ² Any optimizer connected to an operating inverter in a string is bypassed automatically if it fails.
• ³ Once an optimizer stops working, output voltage drops to 0 V.
• Installation: frame mounting bracket / T-shaped bolt (for PV module frame/extruded aluminum profile racking).
• ⁵ Between 70–85°C the unit may shut down on over-temperature protection and alarm; it resumes automatically once temperature drops, without damage.

PV System Design (SUN5000-8K/12K-MAP0)
• Min. string length (power optimizers): 6
• Max. string length (power optimizers): 35
• Max. DC power per string: 12,000 W
Notes:
• ¹ Max. input voltage is the DC upper limit — a higher input DC voltage would likely damage the inverter.
• ² Any DC input voltage beyond the operating range may cause malfunction.
• ³ The SUN5000 Series inverters must be fully equipped with optimizers, otherwise the system reports errors and cannot work.
