The direct current from the PV modules is converted into heat directly in the storage tank without an upstream inverter.\u003c\/p\u003e \u003cp\u003eThe device belongs to the 80-liter class and has an actual usable capacity of 77 liters. Thanks to the integrated mains reheating, the hybrid boiler can replace a conventional electric boiler and maintain an adjustable minimum temperature even when solar radiation is low.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eFor photovoltaic operation, a heating output of up to 550 W is available. An integrated MPP tracker adjusts the electrical operating point to the available solar power. The current water temperature, PV input power, input voltage, and total photovoltaic energy used can be read on the digital display.\u003c\/p\u003e \u003cp\u003eA second heating element enables reheating with 1,500 W via the 230 V mains supply. The desired minimum temperature is set using a rotary thermostat. If the water temperature falls below this value, the water is automatically reheated using mains electricity.\u003c\/p\u003e \u003cp\u003eThe pressure-resistant storage tank is made of enamelled steel and is additionally protected against corrosion by a magnesium anode. The thermal insulation made of CFC-free polyurethane foam reduces standby heat losses. The PVB-80-AC has energy efficiency class C, load profile M, and a sound power level of 15 dB.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eHot water preparation is primarily carried out using directly available photovoltaic energy. The mains reheating only takes over when the minimum temperature set on the thermostat is not reached. This allows the proportion of mains electricity to be reduced without having to do without weather-independent hot water supply.\u003c\/p\u003e \u003cp\u003eAt maximum PV heating output, the water temperature increases by approximately 6 °C per hour. The 1,500 W mains reheating achieves a temperature rise of about 16 °C per hour. If the storage tank is fully heated to 65 °C, approximately 180 liters of hot water at around 34 °C can be provided when mixed with cold water.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eThe photovoltaic modules are connected directly to the hybrid boiler via MC4 connectors. Multiple modules may only be connected in parallel. For the 80-liter model, a photovoltaic output of 600 to 1,200 Wp is recommended. In total, up to 2,000 Wp can be connected, while the heating output of the boiler remains limited to a maximum of 550 W.\u003c\/p\u003e \u003cp\u003eThe maximum open-circuit voltage of the connected modules must not exceed 42.4 V DC. For automatic grid-assisted reheating, the existing 230 V connection is connected to a suitable socket. Photovoltaic modules, parallel connectors, extension cables, and mounting systems are not included in the standard scope of delivery.\u003c\/p\u003e \u003c\/div\u003e \u003cstyle\u003e .product-th{margin-top:2rem}.product-th h2{margin:0 0 1rem}.product-th__table{width:100%;border-collapse:separate;border-spacing:0}.product-th__table td{padding:.95rem 1rem;vertical-align:top}.product-th__label{font-weight:700;width:38%;color:#213670}.product-th__value{color:#1f2937}.product-th__table tr:nth-child(odd) td{background:#f4f7fb}.product-th__table tr:nth-child(even) td{background:#fafbfd} \u003c\/style\u003e \u003cdiv class=\"product-th\"\u003e \u003ch2\u003eTechnical Data at a Glance\u003c\/h2\u003e \u003ctable class=\"product-th__table\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eStorage Type\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003ePressure-resistant solar electric wall-mounted storage tank\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eUsable Capacity\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e77 liters\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eSuitable for drinking water\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eYes\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eStorage tank\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eSteel with enamel coating\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eHeat exchanger\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eNone\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eInsulation\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eCFC-free rigid polyurethane foam\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eMaximum water temperature\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e65 °C\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eMaximum operating pressure\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e7 bar\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eEnergy efficiency\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eClass C, load profile M\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eDimensions\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eHeight 900 mm, width 480 mm, depth 470 mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eWeight\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e25 kg\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eInstallation\u003c\/h2\u003e \u003cp\u003eThe PVB-80-AC is intended exclusively for vertical, fixed wall mounting in a dry and frost-free room.
