H5001STK Hybrid Inverter

Model Number: H5001STK
Stacking of hybrid inverters is incredibly useful. Generally you are limited by the inverter in how much power and energy you can use and supply to your household. But what happens if you need more?

The Darfon H5001STK hybrid inverters feature a stacking ability so you can configure your system to fit your site specific demands. Stacking two hybrid inverters for up to 14kW to essential load with grid present and 8.8kW without. If that is not enough, you can stack a third hybrid inverter for up to 21kW to essential load with grid present and 13.2kW without.
  • Battery Capacity
    Stacking not only increases the amount of power, it also increases the energy storage capacity. Each hybrid inverter has its own charging capability and can be controlled to work together. So you can incrementally add power and storage in parallel at the same time. This makes designing and configuring sites with larger demands easier. Below are a few possible system configurations.
