Climate Change Ready Solution for a Fragilized Grid
Two solar heat pump variants are available within the same unit: the hybrid and the off-grid heat pump.
The hybrid heat pump operates mainly on solar energy and is powered by the electrical grid when needed. Typically, energy produced by solar panels is used during sunny periods while the energy from the grid is used to make up the shortfall during non-sunny periods.
The heat pump does not require a grid connection to operate: the unit will automatically adjust its speed and heating or cooling capacity to the available solar power. However, a connection to the grid will be necessary if the unit needs to operate when there is no sunlight.
A DC booster can be installed on the outdoor unit of the heat pump to make it off-grid. This booster makes it work with batteries at all times. Knowing that it works only with solar energy, it allows its user to realize more energy and monetary savings.
The heat pump can be powered by any 48V battery bank (lead-acid, AGM, Gel or lithium), meaning it can be installed on any solar energy system that utilizes a 48V battery bank.
The solar heat pump connects to Wi-Fi: it can be remotely controlled using the app (available free on iOS and Android). The app allows you to adjust the temperature, the fan speed and to program the unit. Optimizing energy consumption has never been easier.
Eco-responsible, the solar heat pump uses free energy during sunny periods and limits energy needed during the non-sunny periods by using heat pump technology to heat or cool the premises. Moreover, in the case where the local electric grid uses non-renewable resources to produce its electricity, the solar heat pump helps reduce your carbon footprint.
The hybrid installation requires only solar panels and a public electrical grid. The solar panels power the heat pump during sunny periods and the grid fills in the gaps when needed. Between 1200W and 2695W of solar panels are required on the DC input side. The connection of the solar panels can be in series, parallel or both(series + parallel). On the AC side of the unit, the 220VAC public electrical grid must be connected.
Off-grid installation requires the installation of more solar equipment. Solar panels charge a battery bank through a charge controller. The battery bank feeds the DC Booster which feeds the heat pump. The quantity of solar panels to be installed is not limited by the input voltage accepted by the heat pump, but by that of the charge controller. The more powerful the charge controller is, the greater the quantity of solar panels that can be installed. However, a minimum power of 1200W is recommended.
The heat pump can be powered by any type of battery (lead-acid, AGM, Gel or lithium), as long as the battery bank voltage is 48VDC nominal. However, lithium batteries are the best option because their voltage is more stable and they can be discharged to 100%, which offers more energy for the same amp hour rating of batteries. The installation of the DC Booster is imperative for the unit to work since it converts the 48VDC of the batteries into 22VDC-335VDC.
