{"product_id":"fothermo-1-kw-solarheizstab-rod-1000","title":"fothermo 1 kW solar heating rod ROD-1000, direct PV connection without inverter, G 1½","description":"\u003cp\u003eThe fothermo 1 kW solar heating rod ROD-1000 is screwed into a suitable hot water tank with a G 1½ connection and heats the water with direct current straight from PV modules, without an inverter and without a 230 V grid connection for heating operation. An integrated MPP tracker controls the heating power continuously up to 1,000 W. Water temperature and power are shown on the digital display. The solar heating rod relieves the existing gas, oil or pellet heating or heat pump in domestic hot water preparation; when the sun is not shining, the existing heating system takes over.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eRetrofit into existing tanks with G 1½ socket (6\/4 inch), immersion depth 295 mm\u003c\/li\u003e\u003cli\u003eContinuously variable heating power from 0 to 1,000 W, recommended for 1,500 to 2,500 Wp PV power\u003c\/li\u003e\u003cli\u003eDigital display for power and temperature, water temperature adjustable from 5 to 65 °C\u003c\/li\u003e\u003cli\u003eSurplus output: after reaching the set maximum temperature it switches over to a further solar heating rod or a compatible micro PV inverter\u003c\/li\u003e\u003cli\u003eSupplied with two pairs of solar connectors\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eTechnical data according to the manufacturer\u003c\/h3\u003e\u003ctable\u003e\u003ctr\u003e\u003cth\u003eItem number\u003c\/th\u003e\u003ctd\u003eROD-1000\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eEAN\u003c\/th\u003e\u003ctd\u003e4260714970273\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eHeating power\u003c\/th\u003e\u003ctd\u003e0 to 1,000 W, continuously controlled\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eMax. open circuit voltage (Voc)\u003c\/th\u003e\u003ctd\u003e50 V DC\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eMin. module voltage (Vmpp)\u003c\/th\u003e\u003ctd\u003e36 V (max. 800 W heating power)\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eRecommended module voltage (Vmpp)\u003c\/th\u003e\u003ctd\u003e38 to 43 V (for 1,000 W heating power)\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eMax. input current\u003c\/th\u003e\u003ctd\u003e23 A DC, automatic current limitation\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eMax.
