Rated for up to 50W of recommended panel power and 4A charging current, it is well suited to modest off-grid power setups, marine electronics, RV and caravan auxiliary systems, remote monitoring, street lighting, security equipment and battery maintenance applications.\u003c\/p\u003e\u003cp\u003eUnlike simple PWM regulators, the GV-4 uses Maximum Power Point Tracking to help extract more usable energy from a solar panel as light levels, panel temperature and operating conditions change. Genasun specifies 99% typical tracking efficiency, 96% to 99.85% typical electrical efficiency and a fast 15Hz MPPT tracking speed, making this controller a strong choice when solar panel area is limited and every watt-hour is valuable.\u003c\/p\u003e\u003cp\u003eThis 12V lead-acid version is intended for 12V Lead-Acid, AGM, Gel, Sealed and Flooded batteries. The charge profile is multi-stage with temperature compensation, with published bulk, absorption and float voltage settings suited to many conventional 12V lead-acid applications. Battery manufacturer charging specifications should still be checked as part of system design.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e50W solar input rating:\u003c\/strong\u003e Designed for small 12V nominal solar panels with up to 50W recommended panel power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4A rated charge current:\u003c\/strong\u003e Suitable for compact lead-acid battery charging and maintenance systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-speed MPPT:\u003c\/strong\u003e Tracks the panel maximum power point at 15Hz to adapt quickly to changing sunlight.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVery low consumption:\u003c\/strong\u003e Uses 0.125mA while operating and 0.09mA at night, helping reduce battery drain during poor weather or storage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact enclosure:\u003c\/strong\u003e The 80g controller measures approximately 11cm x 5.6cm x 2.9cm for easy installation in space-limited electrical compartments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eEfficient charging for small solar systems\u003c\/h3\u003e\u003cp\u003eThe GV-4 is designed for systems that need dependable solar charging without the size and overhead of a larger regulator. It can be used to connect a small panel to a 12V lead-acid battery for loads such as lighting, communications equipment, mobile device charging through a suitable downstream system, remote instrumentation or standby battery support.\u003c\/p\u003e\u003cp\u003eGenasun highlights the GV-4’s low-light efficiency and small self-consumption as key advantages for installations that may spend long periods under cloud, partial shade or intermittent sun. The controller includes a multicolour LED status indicator for standby, charging, current limit, charged and fault conditions, giving installers a simple way to check operating state at the unit.\u003c\/p\u003e\u003ch3\u003eInstallation-focused design\u003c\/h3\u003e\u003cp\u003eThe controller uses a 4-position terminal block for 12 to 30 AWG copper conductors. The manual specifies that the controller does not include a fuse, so suitable overcurrent protection must be provided in the installation. It also notes that loads should be connected directly to the battery, as the GV-4 does not provide protection against over-discharge.\u003c\/p\u003e\u003cp\u003eThe GV-4-Pb-12V is a neat, efficient solution for small 12V lead-acid solar charging projects where compact size, MPPT harvesting and low operating draw are important buying priorities.\u003c\/p\u003e","brand":"Genasun","offers":[{"title":"Default Title","offer_id":47412920615061,"sku":"GV-4-Pb-12V","price":99.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/8974\/5557\/files\/gv4-pb-12v-middle.webp?v=1780668150","url":"https:\/\/www.exotronic.com.au\/products\/genasun-4a-mppt-12v-lead-acid-solar-charge-controller","provider":"Exotronic","version":"1.0","type":"link"}
