It suits off-grid installations where a simple, cost-effective charging solution is needed, and the built-in LCD display with USB output makes it practical for smaller sites where basic monitoring and device charging matter.\u003c\/p\u003e\u003ch2\u003eKey features of this solar charge controller\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem voltage\u003c\/strong\u003e, 48V, with a 30A charge current capacity for medium-sized off-grid arrays.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharging method\u003c\/strong\u003e, PWM algorithm, tapering current as the battery approaches full charge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay\u003c\/strong\u003e, built-in LCD showing battery voltage, charge current and charge state.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSB output\u003c\/strong\u003e, charges small devices directly from the solar system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e, 0.3 kg, straightforward to mount in enclosures or on DIN rail with appropriate accessories.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow it works\u003c\/h2\u003e\u003cp\u003ePWM charge controllers connect the panel directly to the battery once the battery reaches its set voltage, then switch the connection on and off rapidly to hold the correct charge level. This suits systems where panel voltage is closely matched to the battery bank voltage. For a 48V bank, the array should be configured to a voltage compatible with PWM operation, around 60V open-circuit or less depending on temperature.\u003c\/p\u003e\u003cp\u003eThe LCD gives a clear read of system status without a separate monitoring device or app, useful on remote or standalone sites. There is no Bluetooth or VE.Direct connectivity on this unit. Installations needing remote monitoring or integration with a Victron GX device should look at the SmartSolar or BlueSolar MPPT range instead. This PWM-LCD\u0026amp;USB range suits budget-conscious, straightforward off-grid builds.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eOff-grid cabins and rural buildings with 48V battery banks, agricultural or smallholding installations, backup power systems, telecoms enclosures on 48V DC, and educational or demonstration solar setups.\u003c\/p\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eUse with 48V battery systems only. Connecting to a different voltage bank causes incorrect operation or damage. Check the array open-circuit voltage is within the controller's rated input limits before connecting, and fuse and size all wiring for the 30A charge current. Installation should be carried out by a qualified electrician or experienced installer. Not suitable for grid-tied or hybrid systems.\u003c\/p\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1 x Victron BlueSolar PWM-LCD\u0026amp;USB 48V-30A charge controller\u003c\/li\u003e\u003c\/ul\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52095575982368,"sku":"SCC040030050","price":28.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-scc040030050-1.webp?v=1785754258","url":"https:\/\/www.ledandsolar.co.uk\/products\/bluesolar-pwm-charge-controller-48v-30a","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
