1. Product Positioning
The R0388 is a high-power US-standard split-phase off-grid inverter with integrated control functions, specially designed for 51.2V lithium battery systems. It features a rated split-phase output power of 12,000W and integrates four key functions: AC mains charging, dual independent MPPT solar charge controllers, pure sine wave inverter and bypass switching.
Designed specifically for North American residential applications, villas, large RVs and overseas off-grid energy storage projects, the R0388 supports up to 6 units connected in parallel for capacity expansion and is compatible with both lithium iron phosphate (LiFePO₄) batteries and lead-acid batteries.
