Built as a connectorised PCB module, it brings the proven GV-5 platform into a plug-in format that can integrate directly with a host PCB, helping reduce wiring, assembly time and enclosure space in small solar-powered products.\u003c\/p\u003e\u003cp\u003eThis Li version is intended for 11.1V 3S or 14.8V 4S Li-ion LiPo, LiCoO2, LiMn or LiNi battery configurations, with selectable CC\/CV charge profiles via the charge profile pin. The default profile provides a 12.5V CV setpoint for 3S packs, while the secondary profile provides a 16.7V CV setpoint for 4S packs. That makes it well suited to engineered low-power systems where the charge voltage must be matched carefully to the battery pack design.\u003c\/p\u003e\u003cp\u003eWith high-speed Maximum Power Point Tracking and typical electrical efficiency up to 99.85%, the GV-5-MOD Li is built to harvest more usable energy from small PV modules than a basic PWM controller, particularly when light levels are changing. The controller is rated for up to 55W on the default 3S profile and up to 75W on the 4S profile, with a 27V maximum input voltage and a recommended maximum panel Voc of 22V at STC.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmbedded PCB format:\u003c\/strong\u003e 24-pin dual-row shrouded header for direct integration into OEM products and compact control boards.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual lithium profiles:\u003c\/strong\u003e Selectable 3S and 4S Li-ion CC\/CV charge profiles using the charge profile select input.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5A rated output:\u003c\/strong\u003e Supports up to 5A battery charge current and a 5A continuous load output with low voltage disconnect.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficient MPPT operation:\u003c\/strong\u003e High-speed 15Hz tracking with 99+% typical tracking efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow standby draw:\u003c\/strong\u003e 0.125mA standby consumption helps reduce parasitic drain in unattended solar systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal indication options:\u003c\/strong\u003e Red and green LED outputs support external status and error indication in a finished product.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesigned for compact engineered solar products\u003c\/h3\u003e\u003cp\u003eThe GV-5-MOD Li is a strong fit for applications such as portable equipment, environmental monitoring, asset tracking, pay stations, kiosks and other low-power off-grid electronics where a purpose-built embedded solar charging module is preferred over a cased controller. The module uses a 0.100 inch gold-plated 24-pin shrouded header and provides connections for panel, battery, load, charge profile selection and LED outputs.\u003c\/p\u003e\u003ch3\u003eImportant lithium system considerations\u003c\/h3\u003e\u003cp\u003eGenasun specifies that Li controllers use the CC\/CV charging profile indicated on the controller. The battery pack specifications must be checked to ensure the CV voltage is correct, and the power supplied by the solar array and controller must be within the battery pack design limits. Genasun also recommends using a lithium battery with a Battery Management System capable of disconnecting the solar charge controller if any cell is outside its rated temperature, current or voltage range.\u003c\/p\u003e\u003cp\u003eFor compact embedded solar builds that need efficient, low-consumption MPPT charging in a PCB module format, the GV-5-MOD Li provides a proven Genasun solution for carefully specified 3S and 4S Li-ion systems.\u003c\/p\u003e","brand":"Genasun","offers":[{"title":"Default Title","offer_id":47412920483989,"sku":"GV-5-MOD-Li","price":139.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/8974\/5557\/files\/vertical-1_0c58f625-42c9-43df-8b48-9425bbaef4d4.webp?v=1780668105","url":"https:\/\/www.exotronic.com.au\/products\/genasun-12v-5a-li-mppt-solar-charge-controller","provider":"Exotronic","version":"1.0","type":"link"}
