12kW Rated Power Built to Handle Your Highest-Draw Appliances at the Same Time

The WattCycle 12kW hybrid inverter integrates a 120V/240V pure sine wave inverter, an 24,000W MPPT solar charge controller, and a 250A AC charger into a single wall-mount unit. Combining three components into one reduces installation complexity, minimizes wiring, and frees up wall space, while ensuring every part of your solar power system works in coordination from a single interface.

True 120V/240V Split Phase Output for Every Appliance in Your Home

This split phase inverter delivers true 120V/240V output at the same time, so every appliance draws power without restrictions or manual load management. Refrigerators, microwave ovens, televisions, clothes dryers, washing machines, water heaters, ovens, air conditioners, electric stoves, and EV chargers all operate at full capacity concurrently. The same voltage compatibility extends to RV installations, making this solar power inverter a single solution for both residential and mobile power needs.

12kW Rated Power Built to Handle Your Highest-Draw Appliances at the Same Time

With 12kW of continuous rated output and an 18kW peak, this home solar inverter is sized for real household demand. The 250A battery charge current and 270A maximum discharge current give this solar inverter system the throughput to sustain heavy loads consistently, not just in brief bursts under ideal conditions.

Dual 12000W MPPT Inputs That Maximize Solar Harvest Across Your Entire Array

Two independent 12000W MPPT channels accept up to 24,000W of combined PV input, allowing panels installed on different roof sections, angles, or orientations to be managed separately. Each channel tracks its own maximum power point independently. At 98% conversion efficiency, WattCycle hybrid solar inverter captures and converts more of what your panels generate, supporting faster battery charging and longer daily operating hours on solar before drawing from grid or battery reserves.

21 Protection Functions and ≤10ms UPS Transfer Time for Safe, Uninterrupted Power

Reliable solar power starts with protection that operates automatically. This 48V hybrid inverter includes 21 built-in protection functions covering CT anti-reverse current, overload, undervoltage, short-circuit, overcurrent, overvoltage, and overtemperature, with an automatic AC circuit breaker providing additional hardware-level safeguarding. The ≤10ms UPS transfer time switches the system to battery power faster than most sensitive electronics can register a disruption, keeping computers, medical devices, and smart home systems operating without interruption during grid failures or voltage fluctuations.

Power Your Way with 4 Flexible Charging Modes

With 4 intelligent charging modes, you can easily adapt your energy strategy to changing conditions. Use solar power when available, rely on the grid when needed, or combine both sources for maximum efficiency. All settings and operation adjustments can be easily managed through the built-in LCD screen, giving you a simple and intuitive way to monitor and control your energy system. This 12kW hybrid inverter puts you in complete control of your power usage while reducing electricity costs and keeping your home powered when you need it most.

Smart Energy Management with Peak-Valley Arbitrage

Take control of your electricity costs by charging your battery when energy prices are lower and using stored power during peak-rate hours. Combined with solar generation and intelligent charging and discharging strategies, this WattCycle inverter helps optimize energy usage, improve efficiency, and create a smarter, more cost-effective home power solution.

Ultra-Quiet Operation for Flexible Home Installation

The WattCycle 12kW Hybrid Solar Inverter intelligently adjusts fan speed according to internal temperature and load conditions. Under lighter loads, it operates at near-silent levels, while the maximum noise level stays ≤60dB even during higher power demands. This quiet performance makes it suitable for installation in utility rooms, hallways, or locations near bedrooms, providing reliable energy management without adding noticeable noise to your home.

One Solar Inverter System Compatible with Every Major Battery Brand

The WattCycle 12000W split phase inverter supports SLD, FLD, GEL, and LFP (LiFePO4) battery chemistries and communicates over both CAN and RS485 protocols. Pre-configured compatibility covers leading battery brands including Pylon, Growatt, Dyness, Fox-ess, Gotion, and Pace, so integration with your existing or planned battery system requires no custom configuration. Designed for off-grid villas, commercial workshops, agricultural production facilities, and urban residences, this solar inverter system adapts to the demands of each environment without hardware modification.

FAQ about 12kW All-in-one Solar Inverter

A: The definitive upgrade in the V2 model is the massive expansion of its solar charging capacity, moving from the original 18kW (9kW + 9kW) to an industry-leading 24kW (12kW + 12kW) Dual MPPT Solar Input.

Here is exactly how this 200% oversizing capacity transforms your home power backup:

  • Conquer "Poor Weather" Anxiety: Solar panels rarely hit 100% efficiency due to winter low-sun angles, overcast skies, or morning haze. With a 24kW limit, you can over-panel your roof. Even if a storm drops your panel efficiency to 50%, your system is still pulling a full 12kW of raw power to run your home and top off your batteries.
  • Lightning-Fast Recharging: Paired with our 250A massive charging capability, the dual 12kW MPPT channels harvest maximum solar energy.
  • Zero Space & Panel Constraints: You no longer need to worry about splitting odd strings of high-wattage modern panels. The 12kW+12kW independent dual channels allow you to point panels in different directions (e.g., East/West roofs) to maximize daylight capture from sunrise to sunset.

Yes. The WattCycle 48V 12kW is a true hybrid solar inverter that operates in both on-grid and off-grid modes. In hybrid mode, it draws from solar, battery, and the grid simultaneously based on your configured priority. In off-grid mode, it operates completely independent of the utility grid, making it suitable for remote properties, off-grid cabins, and backup power systems.

A: Yes, you can. However, the inverter’s auto-sleep behavior depends on active inputs and loads:

  • Auto-Sleep Threshold: When the AC load drops below 25W, the inverter will automatically enter sleep mode after about 5 minutes to conserve battery life.
  • Solar Override: If there is active PV (solar) input, the inverter will stay awake to manage the incoming solar energy and will not enter sleep mode.
  • Pro-Tip for Evening/Night: During dusk or overcast periods when solar input drops below 15W, the inverter's standby self-consumption (80–120W) may exceed the solar generation. To prevent unnecessary battery drain at night or during weak sun conditions, we highly recommend manually turning off the inverter's AC output.

A: Yes, absolutely! While our inverter is a heavy-duty split-phase system, it natively supports Single-Phase 120V Dual Modes for standard household setups or RV integrations without complicated wiring.

Here is how to set it up as a standard 120V system:

  • AC Input (Charging): Connect your line only to L1 and N (leaving L2 disconnected).
  • AC Output (Load): Draw your power directly from L1 and N to power your standard 120V appliances or sub-panel.
  • Inverter Setting: Configure your output priority to Battery Priority (SOL).
  • The Result: The system bypasses the 240V split-phase requirement and directly outputs standard, stable 120V utility-style power—making it perfect for RV parks, mobile workshops, or simple DIY emergency backups.

Yes. This inverter delivers true 120V/240V split phase output, which is fully compatible with standard North American residential wiring. It can power 240V high-draw appliances including central air conditioners, electric dryers, water heaters, electric ovens, and EV chargers simultaneously, without requiring load management or manual switching between circuits.

When the utility grid fails or drops below acceptable voltage, this hybrid solar inverter switches to battery power in under 10 milliseconds. That transfer speed is fast enough to prevent sensitive electronics, including computers, NAS drives, medical equipment, and smart home systems, from registering any interruption. Most devices require a transfer time under 20ms to avoid a restart, so the ≤10ms response provides a reliable safety margin.
