System integration

Heat pump, solar, battery and EV charging — run as one system.

Heat pumps, solar PV, batteries and EV charging can be coordinated to use more electricity on site and shift demand to suitable tariff periods. We assess equipment compatibility, controls and your energy use before agreeing what the system will do.

How it works

One management system, deciding for every device.

An Energy Management System (EMS) can coordinate compatible equipment. The controls, supported devices and information available to it are confirmed during design; we do not assume every product connects to one platform.

Monitor

Confirm which generation, consumption and tariff information the selected controls can read.

Decide

Set schedules around the tariff, available generation, storage and the building’s needs.

Coordinate

Compatible devices may be scheduled around solar generation or off-peak tariffs, while maintaining heating and hot-water requirements.

Deliver

Compare expected self-consumption and running costs, and confirm the monitoring available from the selected equipment.

Flat cross-section of a two-storey UK home fitted with a rooftop solar photovoltaic array, a hybrid inverter, a battery, a smart meter, a consumer unit and an indoor heat pump. It shows one moment: a sunny afternoon, when the array is covering the whole house and the surplus is charging the battery. Direct current runs from the array through the loft and down to the inverter, which converts it to alternating current for the consumer unit; from there separate final circuits feed the household lights, sockets and appliances and, on its own circuit, the heat pump. The grid connection - a pole in the garden, an overhead service to the meter on the outside wall, and the meter tail through to the board - is drawn in full but is idle at this moment and shown in grey. The heat pump combines that electricity with environmental warmth collected from the ground, the air or water, and sends useful heat to underfloor heating, a first-floor radiator and the coil inside the hot-water cylinder. The refrigerant is sealed inside the machine and is shown both in its real service window and enlarged in a detail circle. The tap water is kept completely separate from the heating water.

  • Environmental warmth collected from the ground, air or water Warmth from your energy source
  • Heating water: warm out to the home, cooler back Hot-water cylinder; MasterTherm AquaMaster heat pump; Heating coil - heating water never mixes with your tap water; Underfloor heating in the screed; Underfloor manifold; Radiator
  • Tap water, kept completely separate from the heating water Your shower and taps; Cold water mains
  • The grid connection, drawn but not running at this moment Electricity meter; Grid connection
  • Alternating current from the inverter to the board and the house Consumer unit - the fuse board; Lights, sockets and appliances; The heat pump is a load like any other
  • Direct current from the roof to the inverter and the battery Solar PV array on the roof; Direct current to the inverter; Inverter - turns DC into AC; Battery - stores the surplus
  • Refrigerant sealed inside the heat pump

The four steps inside the heat pump

  1. 1 Collect evaporator Environmental energy warms the refrigerant until it boils. It leaves as a warm gas at low pressure.
  2. 2 Squeeze compressor Electricity drives the compressor, squeezing that gas into a much smaller space. It leaves hot and at high pressure.
  3. 3 Release condenser The hot gas hands its heat to your heating water and condenses. It leaves as a hot liquid, still at high pressure.
  4. 4 Reset expansion valve A valve drops the pressure and the liquid flashes cold. It leaves as a cold mist, ready to collect more.
What it connects

Four technologies, working to one plan.

Integration can start with a heat pump and solar PV. Battery storage or EV charging may add flexibility, subject to compatibility and a cost assessment.

Solar PV

Compatible controls can direct solar surplus to suitable loads or storage. The available functions depend on the equipment and agreed design.

Explore solar PV

Battery storage

Batteries charge from solar surplus or cheap off-peak electricity and discharge through expensive peak periods — peak shaving that cuts what the site imports when prices are highest.

Explore battery storage

Heat pump

Heating cycles are scheduled to coincide with solar generation or low-cost tariff windows and coordinated with the battery to avoid peak periods. MasterTherm units add their own remote supervision through MasterTherm Online.

EV charging

Vehicles charge when electricity is cheapest or when solar generation peaks — without overloading the site's supply.

Tariff intelligence

Built for the way electricity is priced now.

Time-of-use tariffs offer different prices during the day. Compatible controls may schedule heating, hot water or EV charging around those periods, within the comfort and operating limits agreed for the site.

Battery capacity, tariff terms and export arrangements affect when storage is useful. We assess those limits before recommending a control strategy.

Every scale

Integration for homes and commercial buildings.

Homes and residential

  • Whole-home coordination

    Heat pump, solar PV and battery working together, with smart EV charging from solar surplus.

  • Time-of-use optimisation

    Automatic scheduling around variable tariffs to cut import costs and carbon.

  • Remote monitoring

    Live generation, consumption and battery levels from an app or browser.

Commercial and industrial

  • Solar PV and battery storage

    Coordinate generation and storage around the site’s demand, electrical supply and tariff.

  • Demand-charge control

    Assess whether shifting demand or using storage can reduce peak imports under the site’s tariff.

  • Monitoring and reporting

    Continuous supervision with alerts and detailed reporting for site operators.

Questions

System integration, answered.

It means coordinating compatible technologies through an agreed control strategy. An Energy Management System (EMS) may help, but the functions and supported equipment need to be confirmed for your site.

No. Start with the equipment you have or plan to install. We check compatibility and whether coordination, storage or EV charging would add value before recommending an upgrade.

Peak shaving means reducing the highest imports from the grid, for example by shifting a load or using stored electricity. Any saving depends on the tariff and how much demand can be moved without affecting the building’s needs.

Monitoring depends on the selected equipment and controls. MasterTherm heat pumps support remote supervision through MasterTherm Online. We confirm any wider monitoring, alerts and reporting in the agreed scope.
