Buy a MY-PV heating element and make good use of excess electricity

A MY-PV immersion heater converts excess solar power into hot water, significantly increasing self-consumption. The screw-in heating elements are available in two power classes: 3 kW single-phase and 9 kW three-phase. Thanks to low thermal surface stress, the heating elements achieve an above-average lifespan. The integrated bimetallic thermostat allows for manual temperature adjustment between 34 and 78 degrees Celsius via a rotary knob on the housing.

Purchasing a MY-PV heating element is particularly worthwhile for systems of 5 kWp and above, where surplus energy is regularly generated. The stepless control utilizes even small power surpluses from 100 watts and continuously adjusts the heating output. Once the target temperature is reached, the device switches off automatically, and the power manager enters standby mode. A safety temperature limiter prevents overheating at 98 degrees Celsius. Installation is via a standard 1,5-inch thread in a fresh water or buffer tank with a maximum operating pressure of 10 bar.

The screw-in heating elements operate with a safety plug and a 2,8-meter connection cable for easy installation. The power managers automatically detect when the thermostat switches off and minimize power consumption to just a few watts. Heating elements without a thermostat are also available if required; however, temperature sensors are then mandatory. This is suitable for applications with buffer tanks above 90 degrees Celsius. The horizontal installation position and a 130-millimeter heating-free zone ensure optimal heat distribution within the tank.

Stepless power control through intelligent MY-PV technology

Stepless power control is the key feature of all MY-PV systems. Unlike conventional two-stage heating elements, the power managers operate with precise phase-angle control. The single-phase units regulate between 0 and 3 kW, while the three-phase versions regulate up to 9 kW. This technology enables the full utilization of even the smallest surpluses without grid connection or feed-in. The control process occurs in millisecond intervals and reacts to changes in the energy consumption of other household appliances.

For systems with battery storage, MY-PV takes on a hybrid storage function. The power managers communicate with compatible inverters and prioritize battery charging and hot water preparation according to predefined rules. In conjunction with MY-PV WiFi Meters, operators purchase a complete energy management system. The meters record generation, consumption, and grid feed-in via three-pole connection and transmit data to the control unit via Wi-Fi. The measuring range covers 0 to 60 amps at 230 volts with an accuracy of ±10 percent.

The touchscreen control displays all relevant operating data in real time. Users can see current PV output, heating element output, and storage tank temperature at a glance. Time windows for temperature maintenance can be programmed down to the hour. On days with little sunshine, the systems automatically draw grid power to ensure a minimum temperature. With dynamic electricity tariffs and optional optimization tools, system operators can also take advantage of favorable wholesale electricity prices for hot water preparation at night. Cloud-based optimization is fully automated without any manual intervention.

MY-PV WiFi Meter for real-time monitoring of your solar power system

The MY-PV WiFi Meter measures energy flows at the building's electrical connection and forms the basis for intelligent control strategies. The meters record all three phases separately and detect load shifts between them. The MY-PV Smart Meter technology uses current transformers that are clamped around the power line. Installation requires no interruption of the power supply and is completed in just a few minutes. Communication takes place via Wi-Fi directly with the power managers.

As an alternative to purchasing the MY-PV WiFi Meter, operators can also connect external energy management systems. The control units feature open interfaces for communication with smart home systems from various manufacturers. Excess energy information can be transmitted via Modbus TCP, REST API, or hardware-based communication. This open system architecture allows integration into existing building automation systems without proprietary restrictions. Visualization and analysis are performed either via the MY-PV portal or external platforms.

The MY-PV Energy Meter stores historical data for consumption analysis. Daily, weekly, and monthly statistics show how much surplus electricity was used for hot water. This analysis helps optimize consumption patterns and assess self-consumption rates. With multiple heating elements connected, the system coordinates power distribution according to priority. Upper heating elements in stratified storage tanks are given priority for rapid hot water availability, while lower elements recharge the tank.

Buy a MY-PV power meter for precise energy consumption measurement

When you purchase MY-PV Power Meters, you receive precise measuring instruments for bidirectional energy flows. The devices record feed-in and consumption with high accuracy and low latency. With a one-second update rate, they enable rapid control responses. Installation is in the meter cabinet on a standard DIN rail with IP20 protection. Connection to the power manager is via network cable with RJ45 connectors.

Purchasing the MY-PV Power Meter is recommended for complex installations with multiple consumers. These meters differentiate between self-generated and grid-connected electricity and control the heating accordingly. When drawing power from the grid, the controls reduce the heating output; when there is a surplus, they automatically increase it. This regulation prevents unwanted grid consumption and maximizes the use of self-generated solar energy. The algorithm takes into account the starting currents of other devices and reacts with a defined delay.

For systems with three single-phase heating elements, the three-phase power managers offer special operating modes. The devices operate on different phases and are switched on sequentially. In the case of asymmetrical power supply, the systems optimally utilize the strongest phase. This phase rotation function is particularly advantageous when modules are oriented differently. The 9 kW versions can also directly control three-phase heating elements, ensuring a symmetrical load on all phases. Switching between operating modes is done via menu selection without any hardware changes.
