Heat Your Home with Solar Surplus
Hanergy activates and adjusts your heat pump when solar surplus is available. Temperature setpoint control, HVAC mode switching, and anti-cycling protection — all automatic.
The Problem
Heat pumps are among the most energy-hungry appliances in a home. A typical air-source heat pump draws 2,000-5,000W during operation. Running on grid electricity, that adds up to significant costs over a heating season.
Meanwhile, solar surplus during the day often goes unused or exported at a low feed-in tariff. The thermal mass of a building means heating during solar hours can carry warmth well into the evening.
The Solution
Hanergy monitors solar surplus and activates the heat pump when enough power is available. For dynamic setpoint control, Hanergy adjusts the target temperature based on surplus levels. When surplus drops below the threshold, the heat pump returns to its normal schedule.
Features for Heat Pump Control
Temperature Setpoint Control
Hanergy can raise the target temperature when surplus is available, using the building's thermal mass as free energy storage.
HVAC Mode Switching
Switch between heating modes (e.g., eco to comfort) based on surplus availability, without manual intervention.
Anti-Cycling Protection
Configurable minimum on-time and off-time prevents rapid switching that can damage compressor components and reduce heat pump lifespan.
Multi-Level Priorities
Place the heat pump at multiple priority levels — basic heating at high priority, comfort boost at a lower priority when abundant surplus is available.
Example Configuration
Heat Pump
Type: Dynamic
Priority: 2
Entity: climate.heat_pump
Min power: 2,000 W
Max power: 5,000 W
Min on-time: 30 minutes
Min off-time: 15 minutes
Feedback: sensor.heat_pump_powerThis configuration places the heat pump at priority 2 (below an EV charger, for example). Hanergy activates the heat pump when at least 2,000W of surplus is available and enforces a 30-minute minimum run time to protect the compressor.
