Its heating output is continuously regulated between 0 and 1,000 W depending on the available photovoltaic energy.\u003c\/p\u003e \u003cp\u003eThe solar heating element is suitable for retrofitting suitable hot water tanks with a horizontally arranged G-1-1\/2-inch thread socket. It is particularly intended for tanks up to approximately 500 liters and can support hot water preparation by gas, oil, or pellet heating systems as well as heat pumps.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe photovoltaic modules are connected directly to the heating element via MC4-compatible solar connectors. No connection to the 230 V mains is required for heating operation. An integrated MPP tracker adapts the operating point to the available PV output and continuously controls the heating output.\u003c\/p\u003e \u003cp\u003eThe display shows the current water temperature, the voltage and input power of the photovoltaic modules, the power delivered at the surplus output, as well as the energy quantities recorded for hot water preparation and surplus utilization.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe ROD-1000 uses the direct current of the photovoltaic modules directly for heating the tank water without prior conversion. This allows existing solar energy to be used specifically for hot water preparation and reduces the operating time of the existing heat generator.\u003c\/p\u003e \u003cp\u003eThe recommended connected photovoltaic output of 1,500 to 2,500 W supports a high usable heating output even with varying solar radiation. A total of up to 3,000 W of photovoltaic output may be connected.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eThe connected photovoltaic modules must be wired in parallel. Their maximum open-circuit voltage must not exceed 50 V DC. For the highest possible heating output, modules with an MPP voltage of 38 to 43 V are recommended.\u003c\/p\u003e \u003cp\u003eOnce the set water temperature has been reached, the photovoltaic energy can be routed via the integrated surplus output to a second fothermo solar heating element or a micro-PV inverter approved by fothermo.
