The main function is protecting the connected batteries. The internal BMS collects the data and monitors all essential battery parameters. This way, the Battery Management System preserves the health of your system. The BMS will always make sure that the parameters will stay within a safe operating window. When exceeding the safe operating window, the internal safety contactor opens automatically. This will disconnect all chargers and loads. As a result, the Master LV guarantees a safe and reliable operation. \u003c\/p\u003e\u003cbr\u003e\u003cp\u003eIn addition, the Battery Management System balances the cells of the entire battery installation. This maximizes the capacity and increases the battery cell lifetime. Each MG battery has a built-in slave BMS. This monitors all individual cells in the battery module. The Master LV collects all this data, and intervenes when needed. This way it protects all batteries.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eEasy Installation \u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe Master LV is easy to install thanks to the all in one design. It requires less cables, equipment and installation components. This results in a quick Plug and Play installation. The integrated CAN-Bus protocol automatically detects your system configuration. Moreover, it updates the firmware of all batteries.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eCan-Bus Communication \u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eWith the built-in CAN-Bus connectors the Master LV communicates with the MG batteries, chargers\/loads and third party devices. The two left side ports are reserved for communication with the batteries. The two right side ports are for auxiliary communication. Different CAN-Bus protocols are available in the BMS software. NMEA2000 is the most common protocol. The Master LV includes both RJ45 and M12 connectors. This makes it suitable for any application.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eMG Connect App \u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eMonitor and control the MG Master LV with your smartphone or tablet. Easily enable bluetooth by tapping the green start button three times. Download the MG Connect app in the Play Store or App Store. The Connect App works fast and intuitive and provides direct insight into your system.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eDC Distribution \u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eThe design of the Master LV includes an internal DC-busbar. Easily connect the MG batteries on the left side. The right side of the Busbar is reserved for all kinds of chargers and loads. For example, directly connect your battery charger, electric drive and inverter on the right side. The insulation caps separate the positive and negative terminal from each other. Use a MEGA-Fuse for each positive terminal.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eSafety Contactor \u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eWhen starting up your Master LV, the safety contactor links the left side with the right side of the busbar. During the start-up, no sparks and welding occur thanks to the built-in pre-charge circuit. When shutting down your system it disconnects the batteries from the chargers and loads. Moreover, the contactor opens in case a critical parameter exceeds the limit. This is a second layer of protection.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003e96 Vdc Integration \u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eWith only 4 batteries in series you can easily create a 96Vdc system. The 96Vdc charger is CAN-Bus controlled by the MG Master LV. Connect this charger directly to the internal DC Busbar of the MG Master LV. In addition, connect your electric drive or electric hydraulic motor to the same internal DC Busbar. This principle also works with 72 Vdc electric drives, by installing 3 batteries in series. Add more strings in parallel to increase operating time (kWh).\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eEasy install:\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/yfuzHU48COY?si=VgeUHIya6Zmirut4\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cbr\u003eManufacturer Part Number: MGMLV120400\u003c\/strong\u003e\u003c\/p\u003e","brand":"MG Energy Systems","offers":[{"title":"Default Title","offer_id":56565605532022,"sku":"BAT-LI-MG-BMS-12V-0400A","price":849.19,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1078\/5560\/files\/12ca5ed9-4795-4633-9bfa-be26ed6908cd_b50e5634-516b-40ea-9136-f598241dcac5.png?v=1761930851","url":"https:\/\/shop.chastheboat.co.uk\/products\/es-battery-management-systems-mg-master-lv-12v400a-mgmlv120400","provider":"ChasNewensMarine","version":"1.0","type":"link"}
