It converts 48V DC battery power into clean AC power, while also handling AC battery charging and automatic transfer switching in one unit. That keeps your system layout simpler and helps the power setup behave more like a built-in utility source for backup, off-grid operation, and day-to-day power management.\u003c\/p\u003e\n\u003cp\u003eSplit-phase output delivers both 120V and 240V AC, which supports typical mixed loads without forcing workarounds. The output waveform is pure sine wave, designed for stable power delivery. With 12.0 kW continuous output and 36.0 kW surge power, this inverter charger is sized for systems that need strong headroom for start-ups and short-duration demand spikes. Output frequency is selectable between 50 Hz and 60 Hz, supporting different site requirements.\u003c\/p\u003e\n\u003cp\u003eThis unit includes a built-in automatic transfer switch with a typical transfer time of 10 ms. In practical terms, that supports steadier power when switching between sources. It also supports configurable AC or battery priority operation, so the system behavior can be set based on how the site wants to use AC input and battery energy. Automatic generator start support and remote control give additional control paths for larger battery systems where generator runtime and oversight need to be managed. Battery temperature sensing is included for better visibility and charging management within the system’s supported operation.\u003c\/p\u003e\n\u003cp\u003eOn the charging side, it accepts 240V AC input and supports an AC input voltage range of 184–253 Vac or 140–270 Vac, with AC input frequency listed as 50 Hz or 60 Hz. Charger current is up to 115 A with a charger breaker rating of 80 A. Charger output voltage is dependent on battery type, and it is compatible with multiple battery types including lithium, gel, AGM, and lead-acid. For standby efficiency, idle power consumption is listed at 40 W with power saver on and 180 W with power saver off.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCombines inverter, AC charger, and automatic transfer switch in a single unit\u003c\/li\u003e\n\u003cli\u003eSupports split-phase operation with 120V and 240V AC output\u003c\/li\u003e\n\u003cli\u003eConfigurable AC or battery priority operation\u003c\/li\u003e\n\u003cli\u003eCompatible with multiple battery types including lithium, gel, AGM, and lead-acid\u003c\/li\u003e\n\u003cli\u003eIncludes automatic generator start support, remote control, and battery temperature sensing\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eContinuous output power: 12.0 kW\u003c\/li\u003e\n\u003cli\u003eSurge power: 36.0 kW\u003c\/li\u003e\n\u003cli\u003eOutput waveform: pure sine wave\u003c\/li\u003e\n\u003cli\u003eAC output voltage: 120 V, 240 V\u003c\/li\u003e\n\u003cli\u003eAC input voltage: 240 V\u003c\/li\u003e\n\u003cli\u003eDC battery voltage: 48 V\u003c\/li\u003e\n\u003cli\u003eOutput frequency: 50 Hz, 60 Hz\u003c\/li\u003e\n\u003cli\u003eTypical transfer time: 10 ms\u003c\/li\u003e\n\u003cli\u003eNominal DC input voltage: 48.0 V\u003c\/li\u003e\n\u003cli\u003eMinimum start voltage: 40.0 V, 42.0 V\u003c\/li\u003e\n\u003cli\u003eLow battery alarm voltage: 42.0 V, 44.0 V\u003c\/li\u003e\n\u003cli\u003eLow battery shutdown voltage: 40.0 V, 42.0 V\u003c\/li\u003e\n\u003cli\u003eHigh battery voltage alarm: 64.0 V\u003c\/li\u003e\n\u003cli\u003eBattery voltage recovery: 62.0 V\u003c\/li\u003e\n\u003cli\u003eIdle power consumption (power saver on): 40 W\u003c\/li\u003e\n\u003cli\u003eIdle power consumption (power saver off): 180 W\u003c\/li\u003e\n\u003cli\u003eCharger output voltage: dependent on battery type\u003c\/li\u003e\n\u003cli\u003eCharger current: up to 115 A\u003c\/li\u003e\n\u003cli\u003eCharger breaker rating: 80 A\u003c\/li\u003e\n\u003cli\u003eAC input frequency: 50 Hz, 60 Hz\u003c\/li\u003e\n\u003cli\u003eAC input voltage range: 184–253 Vac, 140–270 Vac\u003c\/li\u003e\n\u003cli\u003eUnit weight: 160 lb\u003c\/li\u003e\n\u003cli\u003eUnit dimensions: 27.6 × 16.5 × 8 in\u003c\/li\u003e\n\u003cli\u003eShipping weight: 185 lb\u003c\/li\u003e\n\u003cli\u003eShipping dimensions: 29.2 × 23 × 16.5 in\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat’s Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e12.0 kW 48V split-phase pure sine wave inverter charger with built-in transfer switch\u003c\/li\u003e\n\u003cli\u003eRemote control\u003c\/li\u003e\n\u003cli\u003eBattery temperature sensing accessory\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eBest For\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eResidential backup power using a 48V battery bank with 120V and 240V loads\u003c\/li\u003e\n\u003cli\u003eOff-grid systems needing 12.0 kW continuous output and 36.0 kW surge power\u003c\/li\u003e\n\u003cli\u003eCommercial or mixed-load sites that require split-phase 120\/240V AC output\u003c\/li\u003e\n\u003cli\u003eSystems that recharge from 240V AC input with adjustable priority behavior\u003c\/li\u003e\n\u003cli\u003eBattery banks using lithium, gel, AGM, or lead-acid\u003c\/li\u003e\n\u003cli\u003eGenerator-supported setups needing automatic generator start support and remote control\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy This One Makes Sense\u003c\/h2\u003e\n\u003cp\u003eThis inverter charger fits installs where you want battery power to run the site in a steady, predictable way.
