{"product_id":"fothermo-solar-hybridboiler-pv-direktanschluss","title":"fothermo solar hybrid boiler with direct PV connection and 230 V backup heating, 30 l or 80 l","description":"\u003cp\u003eThe fothermo solar hybrid boiler is a wall-mounted electric water heater that uses solar power directly for hot water. PV modules are connected to the boiler via MC4 solar connectors without an inverter and without a battery. An integrated MPP tracker controls the PV heating power continuously up to 550 W. If the solar yield is not sufficient, the 230 V backup heater with 1,500 W heats up as soon as the water falls below the minimum temperature set on the thermostat. Without a grid connection the boiler works on solar power alone. The boiler is available with 30 l or 80 l nominal volume.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eDirect PV connection without inverter and without battery, MC4 solar connectors\u003c\/li\u003e\u003cli\u003eContinuously variable PV heating power from 0 to 550 W via one MPP tracker\u003c\/li\u003e\u003cli\u003eAutomatic 230 V backup heating with 1,500 W, thermostat with rotary knob\u003c\/li\u003e\u003cli\u003eDigital display for water temperature, PV power and solar yield\u003c\/li\u003e\u003cli\u003eEnamelled steel tank with magnesium anode, polyurethane foam insulation\u003c\/li\u003e\u003cli\u003e30 l for small draw-off quantities, 80 l for regular showering\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eTechnical data according to the manufacturer\u003c\/h3\u003e\u003ctable\u003e\u003ctr\u003e\u003cth\u003e\u003c\/th\u003e\u003cth\u003e30 l\u003c\/th\u003e\u003cth\u003e80 l\u003c\/th\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eItem number\u003c\/th\u003e\u003ctd\u003ePVB-30-AC\u003c\/td\u003e\u003ctd\u003ePVB-80-AC\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eEAN\u003c\/th\u003e\u003ctd\u003e4260714970136\u003c\/td\u003e\u003ctd\u003e4260714970150\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eStorage volume\u003c\/th\u003e\u003ctd\u003e29 l\u003c\/td\u003e\u003ctd\u003e77 l\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eMixed water 40 °C (calculated, tank 65 °C, cold water 15 °C)\u003c\/th\u003e\u003ctd\u003eapprox. 58 l\u003c\/td\u003e\u003ctd\u003eapprox. 154 l\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003ePV heating power\u003c\/th\u003e\u003ctd\u003e0 to 550 W, continuously variable\u003c\/td\u003e\u003ctd\u003e0 to 550 W, continuously variable\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eRecommended PV power\u003c\/th\u003e\u003ctd\u003e400 to 800 W\u003c\/td\u003e\u003ctd\u003e600 to 1,200 W\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eMax.
