48V 12000w Split Phase Solar Inverter, 110V/220V Output, Wifi, IP21 Rated

12kW Off-Grid Inverter for High-Power Solar and Battery Systems

Built for installations with substantial AC demand, the 12kW split phase solar inverter converts 48V battery power into stable pure sine wave electricity for mixed-voltage circuits. Its 110V/220V output supports appliances, pumps, workshop machinery, refrigeration, communication equipment, and other loads that operate across different voltage levels. The inverter concentrates conversion, protection, and load supply functions in one system, reducing the need for separate power units around the battery bank.

110V/220V Split-Phase Output for Heavy-Duty Electrical Loads

Split-phase architecture allows the inverter to supply both 110V branch circuits and 220V equipment from the same power platform. This helps organize properties where lighting, electronics, motors, and larger appliances require different AC voltages. Pure sine wave output maintains a clean waveform for sensitive devices while supporting inductive loads with higher startup demand.

• 12kW rated AC output for high-demand electrical systems
• 110V/220V split-phase supply for dual-voltage distribution
• 48V battery input for compatible lithium storage banks
• Pure sine wave output for electronics and motor-driven equipment
• IP21 enclosure for indoor equipment rooms and protected installations
• Overload, short-circuit, overvoltage, and temperature protection
• Forced-air cooling for sustained power conversion

High-load equipment can create brief current surges when motors or compressors start. The inverter’s control platform monitors output demand and responds within its stated operating limits. Correct load planning remains important, particularly when several pumps, air-conditioning units, tools, or refrigeration systems may run at the same time.

48V Battery Inverter With Thermal and Fault Protection

A 48V battery architecture helps control current on the DC side compared with lower-voltage systems delivering the same output power. Suitable cable size, fuse ratings, connection torque, and battery discharge capability all affect system stability. Lithium battery communication and voltage settings should match the selected storage equipment before commissioning.

The aluminum housing and internal cooling path help move heat away from power components during long operating periods. Temperature sensing adjusts protection behavior when internal conditions rise beyond the permitted range. IP21 protection guards against contact with internal electrical parts and vertically falling water drops, making sheltered indoor installation the preferred arrangement.

Pure Sine Wave Backup Power for Off-Grid Equipment

The 12kW split phase solar inverter can serve as the central conversion stage in an off-grid or backup energy system. Solar charge controllers or compatible charging equipment replenish the battery bank, while the inverter supplies AC electricity according to the connected load. Stored energy can support selected circuits during grid outages, at remote sites, or where generator runtime needs to be reduced.

System performance depends on balanced circuit distribution. Dividing 110V loads evenly across both legs helps avoid excessive imbalance, while 220V equipment draws power across the full split-phase output. Load schedules can also reduce simultaneous peak demand and extend available battery runtime.

JSDSolar can configure output voltage, communication options, protection settings, monitoring functions, terminal layouts, and enclosure details for project requirements. Technical support may include battery-bank sizing, cable calculations, load grouping, cooling clearance, and split-phase distribution planning.
