Deye SUN-50K-SG01HP3 \u2013 <\/span>50 kW three-phase high-voltage <\/span>hybrid inverter for larger residential and <\/span>C&I systems<\/span><\/h2>\n<\/div>\n
\n

The <\/span>Deye SUN-50K-SG01HP3<\/span><\/strong> (SUN-50K-SG01HP3-EU-BM4) is a 50 kW <\/span>rated, three-phase, <\/span>high-voltage (HV) <\/span>hybrid inverter<\/span><\/strong> designed for larger residential, <\/span>commercial and industrial solar <\/span>systems. With 4 <\/span> independent MPPTs and high-voltage <\/span>(160\u2013800 V) battery support, it <\/span>manages solar panels, storage and the three-phase <\/span>grid in a coordinated manner. The compact, high <\/span>power density design enables a 1.3 <\/span> DC\/AC ratio, reducing <\/span>capital <\/span>cost, <\/span>and thanks to its <\/span>IP65 protection, it can also be <\/span>installed <\/span>outdoors.<\/span><\/span><\/p>\n<\/div>\n

\n

Why choose the <\/span>Deye <\/span>SUN-50K-SG01HP3 inverter?<\/span><\/span><\/h3>\n<\/div>\n
\n

The <\/span>Deye SUN-50K-SG01HP3 inverter<\/span><\/strong> operates with up to <\/span>97.6% maximum <\/span>and 99.9% <\/span>MPPT efficiency, <\/span>ensuring <\/span>economical operation even at high <\/span>power levels. The 4 <\/span><\/span> MPPT controllers enable <\/span>precise <\/span>optimization of individual <\/span>string <\/span>performance, while the 100% <\/span>asymmetric <\/span>(unbalanced) output <\/span>adapts to real-world, <\/span>phase-varying <\/span>loads. The <\/span><\/span> high-voltage <\/span>battery platform delivers higher <\/span>system efficiency and lower <\/span>thermal stress, <\/span>while 6 <\/span>programmable daily <\/span>time periods allow the <\/span>charge\/discharge strategy <\/span>to be tailored to tariffs <\/span>and <\/span>peak shaving. The <\/span> <\/span>inverter <\/span>also supports energy storage from <\/span>diesel generators and <\/span>wind turbines. <\/span> <\/span><\/span><\/p>\n<\/div>\n

    Applications<\/span><\/h3>\n<\/div>\n
    \n

    The <\/span>Deye SUN-50K-SG01HP3 inverter<\/span><\/strong> is ideal for higher energy demand <\/span>residential, <\/span>commercial and industrial <\/span>projects: <\/span>large family <\/span>homes, farms, <\/span>factories and smaller <\/span>solar parks. It is excellent <\/span> for maximizing <\/span>self-consumption, <\/span>reducing <\/span>peak demand <\/span>(peak <\/span>shaving) and <\/span>increasing grid independence, <\/span>when paired with <\/span>high-voltage <\/span>batteries. The <\/span> built-in <\/span>backup function <\/span>maintains power to <\/span>critical loads <\/span>(motor-driven <\/span>equipment, refrigerators, <\/span>air conditioners, machinery) <\/span>during outages, and thanks to AC-coupled <\/span>expandability, <\/span>existing <\/span>installations can be retrofitted <\/span>with <\/span>storage.<\/span><\/p>\n<\/div>\n

    Frequently asked <\/span>questions about the Deye <\/span>SUN-50K-SG01HP3 inverter<\/span><\/h3>\n<\/div>\n
    \n

    What does the SUN-50K-SG01HP3-EU-BM4 designation mean?<\/span><\/strong>
    \nThe “50K” refers to the 50 kW <\/span>rated output, <\/span>“SG01HP3” to the first-generation three-phase, <\/span>high-voltage (HV) hybrid platform, <\/span>and <\/span>“BM4” to the 4 <\/span>MPPT controller version.<\/span><\/p>\n<\/div>\n

    \n

    What is the difference between the SG01HP3 and SG02HP3 platforms?<\/span><\/strong>
    \nThe <\/span>SG01HP3 is the first-generation <\/span>HV hybrid platform <\/span>(typically 160\u2013800 V <\/span>battery voltage, 4 MPPTs on the <\/span>50K), while the newer <\/span>SG02HP3 series <\/span>offers a wider 160\u20131000 V <\/span>battery range and more MPPTs. The choice depends on the <\/span>solar array and <\/span>planned battery <\/span>parameters.<\/span><\/span><\/p>\n<\/div>\n

    \n

    How many solar panels and what size battery can be connected to the SUN-50K-SG01HP3?<\/span><\/strong>
    \nThe inverter accepts up to 65 kW <\/span>PV input across 4 MPPTs, <\/span>and has two <\/span>high-voltage (160\u2013800 V) <\/span>battery inputs <\/span>with a total of up to 100 A <\/span>charge\/discharge current.<\/span><\/p>\n<\/div>\n

    \n

    Can the Deye SUN-50K-SG01HP3 be installed outdoors?<\/span><\/strong>
    \nYes, thanks to <\/span>IP65 protection and <\/span>intelligent cooling, it is <\/span>suitable for outdoor wall <\/span>mounting, with an operating temperature range between \u221240 <\/span>and +60 \u00b0C <\/span>(with derating <\/span>above 45 \u00b0C).<\/span><\/span><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
