1. Split Phase 120/240V Output, 12kW Large Power Capacity

Rated 12000VA split-phase / 7200W single-phase continuous output, peak surge power hits 10800VA to easily start heavy inductive loads like air conditioners, refrigerators and water pumps. Pure sine wave output protects sensitive household electronics without voltage distortion. 10ms ultra-fast switching time between bypass and inverter mode ensures zero interruption during grid blackout.

2. Dual Independent MPPT, Total 12kW PV Input

Equipped with two separate MPPT charge controllers, each supports 6000W solar panel input, total max PV power reaches 12000W. Wide PV voltage range 90~485VDC adapts to various rooftop panel layouts, max PV open circuit voltage up to 500VDC. Independent MPPT tracking avoids power loss caused by uneven shading on different solar arrays.

3. Flexible Battery Compatibility & Powerful Charging

Works with 48V lead acid and lithium iron phosphate batteries, battery working window 44.0~58.6VDC. Max 160A AC charging current and 0~220A adjustable solar charging current, combined AC+PV fast charging shortens battery replenishment time greatly. Built-in reverse connection, short circuit and overcurrent fuse protection for safe battery operation.

4. Expandable Parallel Design & Smart Energy Saving

Allows up to 6 inverters to run in parallel for capacity expansion, suitable for large villas and small commercial energy storage systems. Auto sleep power saving mode activates when load is zero, standby power consumption less than 25W to cut idle energy waste. Built-in multi-level overload protection with graded delay shutdown prevents unit damage under heavy load.

5. Full Certifications & Multi-Way Remote Monitoring

Passed UL1741 and FCC Part15 Class B certification, fully compliant with North American household electrical standards. Comes with USB, RS485, optional WiFi/GPRS communication ports, users can remotely check running data, adjust charge/discharge parameters via mobile APP or PC monitoring platform. Strong environmental adaptability: -10℃~55℃ continuous operation, 5%~95% non-condensing humidity.

1. North American Off-Grid Residential Solar Systems

Perfect match for US/Canada rural off-grid houses without stable municipal grid. Dual MPPT accepts large-capacity solar arrays, 12kW split-phase output fully supports daily household appliances, air conditioners and water heating equipment.

2. Grid-Tied Home Backup Power Storage

For suburban families connected to utility grid, it stores daytime solar power for night use and automatically switches to battery power within 10ms once blackout happens, avoiding loss of refrigerated food, security equipment and essential home loads.

3. Remote Cabins, RV Parks & Farm Power Supply

Suitable for holiday cabins, agricultural farms and RV camps in remote areas. Parallel expansion function can build large energy storage systems to supply multi-household shared power, stable performance adapts to seasonal temperature changes.

4. Small Commercial Store Standby Power

Convenience stores, small offices and workshops can use this inverter with battery packs as emergency backup, protecting cash registers, monitoring equipment and lighting from sudden power failure during peak grid outage seasons.

1. Complete wiring according to split-phase L1/L2/N standard: connect solar panels to two separate MPPT PV terminals, link battery bank to battery port, connect grid and household loads to AC input/output terminals.

2. Power on the unit, set battery type, charging current limit and working mode (off-grid / grid-tied backup) via front LCD panel.

3. Connect WiFi module to realize mobile remote monitoring, check real-time PV generation, battery SOC and load power consumption anytime.

4. Keep the unit installed in dry, ventilated indoor space; do not block air cooling vents to avoid overheating derating.

Q1: Does this inverter fit USA 120/240V split phase home circuit? 

A1: Yes, this model is specially designed for North American split-phase grid, native 120V single / 240V dual phase output, passed UL1741 certification to meet local electrical code requirements.

Q2: Can I install two groups of solar panels with different angles/shades? 

A2: Absolutely, dual independent MPPT controllers track two PV arrays separately, shading on one panel string will not reduce power output of the other group.

Q3: How many inverters can I link together to expand system capacity? 

A3: Maximum 6 identical US-R12000-48 inverters support parallel connection, ideal for large villas or small commercial solar storage projects.

Q4: Can it work with lithium batteries? Do I need extra settings? 

A4: It supports both lead-acid and LiFePO4 batteries. Just switch the battery type parameter on the LCD screen after wiring, the internal charger will auto adjust charging voltage curve accordingly.
