12KW ALL-IN-ONE HYBRID INVERTER
12KW 48V All-in-One Hybrid Solar Inverter | Dual MPPT 160A | Dual AC Output | Pure Sine Wave | Parallel-Ready
ShanPu SP-12KW/48V is an all-in-one hybrid inverter that integrates dual MPPT solar charging, 48V battery management and dual-output DC-to-AC inversion in one unit for large residential, commercial and light industrial storage systems. Two independent MPPT channels harvest power from separate PV arrays and convert it into regulated 48V DC, charging the battery bank at up to 160A while feeding the inverter stage; the controller automatically selects between solar, utility and battery based on the configured priority mode (SUB / SBU / SUF).The dual AC output design separates critical loads from non-critical circuits, while the 160A MPPT charging current and up to 160A AC charging rapidly recharge 48V battery banks after prolonged cloudy periods or heavy discharge. The 48V architecture reduces line losses and supports higher power delivery, and the Pro model adds parallel expansion plus optional WiFi monitoring for larger projects.
Working Principle
Key Advantages
- Dual MPPT for Flexible PV Installation： Built-in dual MPPT trackers (160A total) support two independent solar arrays with different orientations, tilts or panel counts - ideal for complex rooftops. Maximum PV input reaches 15KW with a wide 60-500Vdc tracking range.
- Dual AC Output for Load Zoning： Two independent AC outputs - main output (12KW) and secondary output (6KW on standalone) - separate critical loads from non-critical loads, ensuring priority power supply to essential equipment during low-battery or grid-outage conditions.
- Up to 99% Peak Conversion Efficiency (Pro Model)： The Pro version achieves up to 99% peak efficiency from PV to AC output, minimizing energy loss during solar power conversion and maximizing self-consumption rate - reducing electricity costs over the system's lifetime.
- 160A High-Current Charging and 48V Architecture： The 160A MPPT solar charge current and up to 160A AC charge current rapidly recharge 48V battery banks, shortening recovery time after prolonged cloudy days or heavy discharge. The 48V system reduces line losses and supports higher power delivery.
- Parallel Expansion and Smart Monitoring (Pro Model)： The Pro model supports parallel connection for capacity expansion. Optional WiFi remote monitoring and multiple output priority modes (SUB / SBU / SUF) give users full control over energy source allocation and system performance via mobile devices.
Applications
- Large Residential and Villa Solar Energy Systems： The 12KW output powers large households and villas with multiple air conditioners, electric water heaters, kitchen appliances and home EV chargers. The dual MPPT design supports two separate PV arrays facing different directions, maximizing rooftop solar generation.
- Small Commercial and Retail Establishments： Ideal for small supermarkets, restaurants, guesthouses and offices where combined lighting, refrigeration, HVAC and kitchen equipment require stable 12KW continuous power. The dual AC output allows separate load zoning for critical and non-critical circuits.
- Light Industrial and Agricultural Processing： With 24000VA surge capacity and a 3:1 crest factor, the inverter drives motors, pumps, compressors and small processing machinery in workshops, farms and food-processing sites. The detachable dust cover and -10°C to 55°C operating range suit harsh industrial environments.
- Parallel-Expandable Commercial Power Stations： The Pro model supports multi-unit parallel connection, scaling total capacity beyond 12KW for larger commercial sites, small factories and community microgrids. Users can deploy one unit now and add more as energy demand grows, without scrapping existing equipment.
Typical Configurations
Step 1 - Plan the PV arrays. Design two independent arrays within the 60-500Vdc MPPT window (up to 15KW total) and keep open-circuit voltage below 500Vdc.
Step 2 - Size the 48V battery bank. Match 48V lead-acid or LiFePO4 batteries with BMS; charging current up to 160A shortens recharge time.
Step 3 - Zone the loads. Use the two AC outputs to separate critical circuits (12KW main) from non-critical loads (6KW secondary).
Step 4 - Decide parallel and monitoring. Choose the Pro model for parallel expansion and WiFi monitoring; install within the rated temperature range and IP21 environment.

FAQ
What exactly does an inverter do?
It converts DC power (e.g., from a battery) into AC power (like utility/mains electricity).
Can an inverter power a fan?
Yes, as long as the inverter's rated power exceeds the fan's power consumption. Most fans have low power draw.
What are the three types of inverters?
Square wave, modified sine wave, and pure sine wave.
How many batteries do I need for a 10,000 watt inverter?
Usually a 48V system: at least 4 × 12V 200Ah in series for 48V 200Ah. For longer runtime or higher discharge current, multiple strings can be connected in parallel.
What type of inverter is best for a 200Ah battery?
A pure sine wave inverter, with power matched to the battery voltage (for 12V systems, continuous power is recommended ≤2000W), and avoid deep discharge.
Why does this model use dual MPPT?
Two independent MPPT trackers let you connect two PV arrays with different orientations or panel counts, increasing total solar harvest on complex rooftops.
What is the dual AC output used for?
The main 12KW output and 6KW secondary output allow separate circuits, so critical loads keep priority power during low-battery or grid-outage conditions.
What information should I provide for a quotation?
Please provide the load list, PV array details, battery type and voltage, parallel requirements, quantity and destination country.
