Cheaply operate a smart grid ready heat pump on these specific solar inverters or lose money
Operate SG (Smart Grid Ready) Heat Pumps at lowest running cost, in combination with below compatible inverters
Heat Pumps work on the principal of a heat exchange for space and water heating or cooling. With high solar penetration, heat pumps ( not all ) have become intelligent and adapted as Smart Grid (SG) Ready. These heat pumps are intelligent because they can be switched on and off to heat water, by sensing when solar energy is in excess, a key requirement for lowest running cost.
Solar energy being the cheapest source of energy the focus of home owner is on maximizing Self Consumption for household and not sending excess solar to the grid. Using cheap solar power, Heat Pump is usually the least priority load, switched after 11am, after solar charges the home based battery.
Here is the list of Solar inverter Equipment which can work with heat pumps using compatible relay offered by the same brand.

There are other relatively “easy solutions” for controlling Heat pumps, like the $10 timers. Solar energy heats water in a fixed time window, predetermined by the home owner using a manual timer . But since timer solution is manual, it’s not intelligent or PV optimised. It will miss dynamic weather and live household load conditions.
This is why Path to Green Homes recommends the above solar inverter models where heat pumps can be optimized through Wired Relays connected to the solar inverter. There are also inverter models where heat pumps can be controlled wire less. , read here (#wirefree).
Path to Green Homes has researched that many solar inverters have provision for 4 relays which means that the solar inverter can manage three more such equipment, in addition to a heat pump. These could be an electric car , washing machine , energy storage or other household hold
Path to Green Energy recommends “single brand” solution for Heat Pump control consisting of solar inverter and relay for the best compatibility. This single solution will ensure Maximum self- consumption of solar power by prioritizing loads in this order :
1. Electric Vehicle 2. Household loads 3. Battery storage 4. Heat pump 5. If there is excess solar energy then feed to the grid.
