Intelligent Hybrid Energy Management

The Deye 18kW hybrid inverter intelligently manages power from the solar panels, battery bank, electricity grid and generator.

The system can be configured to prioritise solar energy for immediate household or business consumption. Excess solar power can then be stored in the battery bank for use during the evening, during peak-tariff periods or when grid electricity is unavailable.

Time-of-use settings allow users to schedule up to six charging and discharging periods. This makes it possible to charge batteries during lower-cost periods and use stored energy when electricity prices or demand are higher.
