{"product_id":"pwm-solarni-regulator-hadex-12-24v-40a-usb","title":"HADEX 12–24V\/40A PWM solar controller + USB","description":"The PWM controller allows lead-acid batteries to be charged with a current of up to 30A and enables the connection of PV panels with a maximum output voltage of 25V (for a system voltage of 12V). It is equipped with an LCD display for setting and viewing operating parameters.\u003cbr\/\u003eBrief description of PWM controllers:\nPWM solar controllers connect solar panels directly to the battery being charged and, once the set or specified battery terminal voltage is reached, subsequent regulation is achieved by pulsed current limitation or interruption. This occurs at a frequency of a few to tens of Hz, and on some controllers this is indicated by a flashing LED labelled ‘charge’ or ‘solar’. The controllers are suitable for panels with a system voltage matching that of the battery; otherwise, losses occur as part of the power is wasted due to the panel’s unsuitable V-A characteristics.\n\nTechnical specifications:\u003cbr\/\u003e\u003cbr\/\u003eRated battery voltage range for active charging: 11.5–12.8 V (23–25.6 V)\nLead-acid battery – OPEN – mode b01\nLead-acid battery – GEL – mode B02\u003cbr\/\u003ePb battery – LifePo4 – mode b03\nMax. input voltage: 25 V for a 12 V battery, 50 V for a 24 V battery\nMax. charging current: 30 A\u003cbr\/\u003eUSB output: 2 x 5V\/2A\nDimensions: 187 x 98 x 50 mm\nWeight: 370 g","brand":"HADEX","offers":[{"title":"Default Title","offer_id":54066494472530,"sku":"04280521","price":689.0,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/9624\/1490\/files\/04280521.jpg?v=1784743576","url":"https:\/\/tipa-production.myshopify.com\/en\/products\/hadex-12-24v40a-pwm-solar-controller-usb","provider":"TIPA","version":"1.0","type":"link"}
