System Diagram

Typical Application

  • Maximizing solar self-consumption. During the day, the PV system generates electricity which will be provided to
    the loads initially. Then, the excess energy will charge the battery via Deye hybrid inverter. Finally, the stored energy
    can be released when the loads require it.
  • Providing backup for critical loads: there’re independent critical load output port and grid port. It allows critical
    loads such as refrigerators, routers, lamps, computers and other critical appliances can be powered when the grid
    fails. The system can automatically switch to backup mode within 4 milliseconds. Since the automatically time is
    very short, the critical loads can work smoothly even for Non-inverter type air conditioner.
  • Reducing your electricity bills: Thanks to there’re 6 time periods for battery charge and discharge. Deye hybrid
    inverter allows user to charge the battery at the off-peak time and discharge the battery during peak time. Meanwhile,
    it supports grid peak shaving function which can limit the Max. power from grid.

Working Modes

1. Selling (Only in Cape Town, Consult your local municipality)

  • This Mode allows hybrid inverter to sell back any excess power produced by the solar panels to
    the grid.
  • If the “time of use” is active, the battery energy also can be sold into grid.
  • The PV energy will be used to power the load and charge the battery and then excess energy will flow to grid.
  • Power source priority for the load is as follows: Solar Panels. Grid. Battery (until programmable % discharge is reached).

2. Zero Export To Load

Hybrid inverter will only provide power to the backup load connected. The hybrid inverter will neither provide
power to the home load nor sell power to grid. The built-in CT will detect power flowing back to the grid and
will reduce the power of the inverter only to supply the local load and charge the battery.

Hybrid inverter will not only provide power to the backup load connected but also give
power to the home load connected. If PV power and battery power is insufficient, it will take grid energy
as supplement. The hybrid inverter will not sell power to grid. In this mode, a CT is needed. The external CT will
detect power flowing back to the grid and will reduce the power of the inverter only to supply the local load,
charge battery and home load.
