As winter approaches, Europe faces not only cold weather but also increasing challenges from energy shortages and fluctuating electricity prices. In this complex energy landscape, the combination of solar PV (photovoltaic) systems, energy storage, and heat pumps offers a flexible and efficient solution for home heating. By integrating solar power generation, battery storage, and heat pump technology, households can intelligently manage energy use, store excess electricity during periods of low demand and drawing on this stored energy during peak demand or grid pressure. This creates a reliable, round-the-clock heating solution for zero-carbon living.
A solar heat pump system combines the benefits of solar power generation with the high efficiency of air-source or ground-source heat pumps. Solar PV panels convert sunlight into electricity, which powers the heat pump. The heat pump draws thermal energy from the air, ground, or water, delivering significantly more heat energy than the electricity it consumes—typically, 1 kW of electricity can generate 3 to 4 kW of heat.
By integrating solar PV and storage with heat pump systems, homeowners can not only power household appliances but also use their solar-generated electricity for heating. Heat pumps convert solar electricity into hot water, which can be used both for space heating and for hot water on demand. This significantly reduces the burden on traditional heating systems. With a solar heat pump solution, you no longer need to rely on oil, gas, or biomass fuels, achieving cleaner, more cost-effective heating.
A key advantage of this solution is the ability to store solar energy generated during the day and use it at night. This approach maximizes self-consumption of solar energy, further reducing dependence on fossil fuels. The financial benefits are also compelling: compared to selling electricity back to the grid at low rates, using solar energy for heating yields higher savings, especially with rising oil and gas prices. Moreover, the installation of heat pumps is straightforward and does not require major home renovations.
SolaX, a leading provider of solar and energy storage solutions, offers a heat pump integration solution that is particularly well-suited to achieving efficient, zero-carbon heating during winter. By seamlessly Integrating heat pump into SolaX inverters or energy storage systems with the SolaX Adapter Box G2, households can optimize energy use while maintaining comfort and minimizing costs.
Key equipment in the Solar string inverter+heat pump includes: X3-PRO G2, X3-MIC G2, and X1-Mini G4: Grid-tied inverters that effectively manage solar energy generation and its connection to the home or grid.
SolaX Adapter Box G2: The signal controller that connects to the heat pump via the appropriate interfaces, suitable for a variety of solar system sizes and configurations.
In addition to grid-tied PV systems, the SolaX Adapter Box G2 can be integrated with SolaX hybrid inverters like the X1-Hybrid G4 and X3-Hybrid G4, enabling intelligent control of heat pumps. This allows for efficient energy use, even when sunlight is unavailable.
SolaX's Solar + Storage + Heat Pump solution is particularly suited for:
Detached Homes: For households with larger solar PV systems, SolaX Solar + Storage + Heat Pump can maximize self-generated electricity usage and provide backup power during grid outages.
Areas with Power Supply Issues: During winter energy demand peaks, solar and battery storage systems can store excess energy generated during the day, reducing the need for expensive grid electricity during peak periods.
Periods of Negative Electricity Prices: During periods of negative electricity prices, the heat pump can run at full capacity using grid power, taking advantage of the grid’s incentives or compensation schemes to generate savings.
The SolaX Adapter Box G2 is an advanced heat pump controller, designed to integrate seamlessly with solar PV and energy storage systems. It acts as a bridge between the inverter and the heat pump, enabling intelligent management of energy usage based on real-time solar generation and battery storage levels. Let’s break down the technical aspects that make the Adapter Box G2 an indispensable component for solar-powered heating solutions.
Durability: With an IP65 rating and an operating range of -40°C to 60°C, the Adapter Box G2 can handle extreme weather conditions, making it ideal for outdoor installations.
SG Ready Control: This feature optimizes the heat pump’s performance by using excess photovoltaic energy when available. When activated, it boosts the heat pump’s power output; when deactivated, it ensures stable operation at a preset power level, minimizing reliance on grid power.
Digital Signal Control (Dry Contact Control): Using dry contact technology, this control adjusts the heat pump’s power based on external load changes, with up to 16 different power modes. It prevents the heat pump from exceeding preset limits, ensuring efficient operation and minimizing grid dependency.
Analogue Signal Control: Provides precise power adjustments through a 0-10V analogue output, allowing for fine-tuned control across up to 15 power steps. This ensures optimal efficiency and performance, even under fluctuating load conditions.
Smart Monitoring: The SolaXCloud APP allows users to monitor the system in real time, set schedules, and optimize energy use, ensuring maximum solar power self-consumption.
Comprehensive Connectivity: Seamless integration with inverters, EV chargers, and heat pumps via dedicated communication ports ensures efficient operation across devices.
SolaX’s solar and energy storage heat pump solution offers an innovative approach to zero-carbon heating during the European winter. With features like intelligent scheduling, remote monitoring, and efficient energy storage, households can optimize their solar energy usage, offering a reliable and sustainable heating option throughout the year. This may help reduce reliance on conventional energy sources and could lead to noticeable financial savings.
