It is designed for solar systems, battery banks, and DIY power projects that need reliable disconnect and reconnection behavior without continually draining the battery. Settings are stored in internal flash so your preferred cutoffs, delays, and modes remain after power loss.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the module prevent battery damage without draining the battery itself?\u003c\/h3\u003e\n\u003cp\u003eThe unit offers two protection modes: charging mode to stop charging when a preset voltage is reached, and discharging mode to disconnect the load when battery voltage falls below a set threshold. It supports a manual mode that consumes zero power after relay disconnection, and an automatic low-power standby that keeps standby current to about 5mA.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eManual mode: 0 mA after relay opens; requires button reset.\u003c\/li\u003e\n  \u003cli\u003eAutomatic mode: LED and electronics sleep after 60s; ~5mA standby at 18V.\u003c\/li\u003e\n  \u003cli\u003eInternal flash preserves settings after power loss.\u003c\/li\u003e\n  \u003cli\u003e40A relay handles high-current loads without added hardware.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat adjustable timers and delays can I use for startup and shutdown?\u003c\/h3\u003e\n\u003cp\u003eThe module includes flexible timing controls so you can prevent false triggers from temporary voltage dips or delay reconnection until conditions stabilize. Timers cover short start delays, disconnect delays, and long-duration scheduled cutoffs for maintenance or load cycling.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStart delay up to 99 seconds to avoid surge-related trips.\u003c\/li\u003e\n  \u003cli\u003eDisconnect delay up to 99 seconds for transient protection.\u003c\/li\u003e\n  \u003cli\u003eDisconnect timer up to 99:59:59 hours for scheduled shutdowns.\u003c\/li\u003e\n  \u003cli\u003eSet and view values using the built-in LCD and buttons.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat voltages and currents are supported, and how will this fit in my system?\u003c\/h3\u003e\n\u003cp\u003eThis protector runs across a wide DC range and supports heavy loads, making it suitable for most 12V, 24V, and higher-voltage battery assemblies up to 60V.

Installers, hobbyists, and system builders who need a dependable, configurable low-voltage cutoff and overcharge protector will benefit from the MgcSTEM 2-in-1 module. It’s ideal for off-grid solar arrays, backup battery packs, RVs, marine systems, and any project that needs automatic disconnect\/reconnect behavior without high standby drain. Choose manual mode when you want absolute zero post-disconnect consumption, or automatic mode for hands-off operation with low-power standby and quick recovery when voltage returns.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can this module work with 12V and 24V battery systems?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — it supports DC 5–60V, so it works with 12V, 24V, and higher-voltage battery setups.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What happens to settings after a power outage?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Settings are saved in internal flash memory and are restored automatically after power returns.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"MgcSTEM","offers":[{"title":"Default Title","offer_id":56832610566484,"sku":"B0G7J22RQG","price":50.69,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/mgcstem-front-panel-lcd.jpg?v=1787031799","url":"https:\/\/gardenluxe.co.uk\/products\/mgcstem-low-voltage-disconnect-charging-discharging-protector-2pcs-40a-5-60v-with-lcd","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
