It is designed for small off-grid solar applications where panel space is limited, energy harvest matters, and a reliable low-power controller is required.\u003c\/p\u003e\u003ch3\u003ePurpose-built charging for 3S lithium systems\u003c\/h3\u003e\u003cp\u003eThis model uses a CC\/CV lithium charge profile with a 12.5V CV voltage and disabled battery temperature compensation. That makes it a focused choice for compatible 3S lithium packs, rather than a broad multi-battery controller that needs field programming. The integrated load output supports low voltage disconnect and reconnect at 9.3V and 10.5V, helping protect a connected load from drawing the battery down beyond the controller’s set threshold.\u003c\/p\u003e\u003cp\u003eThe GV-5-Li-12.5V is rated for a 55W panel and 5A battery output current. Genasun’s high-speed MPPT tracking operates at 15Hz, allowing the controller to respond quickly to changing light conditions such as moving shade, cloud cover, mobile platforms or compact solar installations with variable exposure.\u003c\/p\u003e\u003ch3\u003eCompact MPPT performance for small solar installs\u003c\/h3\u003e\u003cp\u003eGenasun lists typical electrical efficiency for this model at 95% to 99.85%, with typical tracking efficiency of 99+%. Its low standby consumption of 0.125mA and operating consumption of 0.190mA make it well suited to remote sensors, small portable power systems, marine electronics, telemetry, signage and other low-load solar applications where quiescent draw matters.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e5A lithium MPPT controller:\u003c\/strong\u003e Configured for 11.1V 3S lithium battery systems with a 12.5V CC\/CV charge profile.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e55W rated panel power:\u003c\/strong\u003e Suitable for small 12V nominal solar panel installations within the published voltage and current limits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow voltage disconnect:\u003c\/strong\u003e Load output disconnects at 9.3V and reconnects at 10.5V for this model.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast solar tracking:\u003c\/strong\u003e 15Hz MPPT tracking helps maintain energy harvest in variable light.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow self-consumption:\u003c\/strong\u003e 0.125mA standby consumption supports unattended low-power systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact enclosure:\u003c\/strong\u003e 11 cm x 5.6 cm x 2.9 cm body with IP40 environmental protection.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBuilt for reliable field use\u003c\/h3\u003e\u003cp\u003eThe GV-5 range uses an electrolytic-free ceramic design and a compact potted-style enclosure with conformal coating, nickel-plated brass and stainless hardware. The controller includes Genasun Overdrive adaptive power-limiting technology, which allows the controller to limit charging current when required while keeping within its operating constraints. The solar input voltage limit must always be observed.\u003c\/p\u003e\u003cp\u003eInstallation is via a 6-position terminal block for 12 to 30 AWG copper wire. The controller should be mounted with adequate airflow, protected from direct water exposure, and installed with suitable external fusing as specified by the manufacturer. For outdoor installations, the manual states the controller must be housed in an enclosure providing at least NEMA Type 3 protection.\u003c\/p\u003e\u003ch3\u003eImportant lithium system considerations\u003c\/h3\u003e\u003cp\u003eThe battery pack’s charging specifications must match the controller’s 12.5V CV lithium profile. Genasun 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, and recommends cell balancing.\u003c\/p\u003e\u003cp\u003eFor compact lithium solar charging where high efficiency, low standby draw and a small physical footprint are priorities, the GV-5-Li-12.5V provides a clean MPPT solution for matched 3S lithium battery systems.\u003c\/p\u003e","brand":"Genasun","offers":[{"title":"Default Title","offer_id":43163721400381,"sku":"GV-5-Li-12.5V","price":139.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0602\/3918\/3933\/files\/GV5-Li-12.5-Middle_f291932d-2ac9-47f0-90a7-471ad172e4c6.webp?v=1778456532","url":"https:\/\/www.solar4rvs.com.au\/products\/genasun-gv-5-12-5v-5a-lithium-mppt-solar-charge-controller","provider":"Solar 4 RVs","version":"1.0","type":"link"}
