Max input 145Vdc,120A dual-MPPT charger,optional Zero Export to Grid, parallel stackable, The Hybrid means the inverters have Grid tied (on-Grid, or Feeding to Grid) functions, standalone off Grid functions, and MPPT solar charge controller function. The hybrid inverters COH normally convert solar panels DC power to supply loads like home appliances directly at first, and charge batteries by MPPT charger if any surplus solar power, and then feeding power to Grid if still any surplus solar power after supplying loads and charging batteries; 

When solar energy is insufficient to run connected loads, the inverter will automatically get energy from batteries if batteries are abundant. If the battery capacity is insufficient to supply loads, the hybrid inverter will get power from Utility Grid.
